Also, there is a sample Makefile in this handbook, so take a look and please follow the ordering of variables and sections in that template to make your port easier for others to read. Now, consider the following problems in sequence as you design your new Makefile: The Original Source Does it live in DISTDIR as a standard gzipped tarball named something like foozolix-1.2.tar.gz? If so, you can go on to the next step. If not, you should look at overriding any of the DISTVERSION, DISTNAME, EXTRACT_CMD, EXTRACT_BEFORE_ARGS, EXTRACT_AFTER_ARGS, EXTRACT_SUFX, or DISTFILES variables, depending on how alien a format your port's distribution file is. In the worst case, you can simply create your own do-extract target to override the default, though this should be rarely, if ever, necessary. Naming The first part of the port's Makefile names the port, describes its version number, and lists it in the correct category. <varname>PORTNAME</varname> and <varname>PORTVERSION</varname> You should set PORTNAME to the base name of your port, and PORTVERSION to the version number of the port. Package name should be unique among all of the ports tree, check that there is not already a port with the same PORTNAME and if there is add one of PKGNAMEPREFIX or PKGNAMESUFFIX. <varname>PORTREVISION</varname> and <varname>PORTEPOCH</varname> <varname>PORTREVISION</varname> The PORTREVISION variable is a monotonically increasing value which is reset to 0 with every increase of PORTVERSION (i.e., every time a new official vendor release is made), and appended to the package name if non-zero. Changes to PORTREVISION are used by automated tools (e.g., pkg version, see &man.pkg-version.8;) to highlight the fact that a new package is available. PORTREVISION should be increased each time a change is made to the port that changes the generated package in any way. That includes changes that only affect a package built with non-default options. Examples of when PORTREVISION should be bumped: Addition of patches to correct security vulnerabilities, bugs, or to add new functionality to the port. Changes to the port Makefile to enable or disable compile-time options in the package. Changes in the packing list or the install-time behavior of the package (e.g., change to a script which generates initial data for the package, like ssh host keys). Version bump of a port's shared library dependency (in this case, someone trying to install the old package after installing a newer version of the dependency will fail since it will look for the old libfoo.x instead of libfoo.(x+1)). Silent changes to the port distfile which have significant functional differences, i.e., changes to the distfile requiring a correction to distinfo with no corresponding change to PORTVERSION, where a diff -ru of the old and new versions shows non-trivial changes to the code. Examples of changes which do not require a PORTREVISION bump: Style changes to the port skeleton with no functional change to what appears in the resulting package. Changes to MASTER_SITES or other functional changes to the port which do not affect the resulting package. Trivial patches to the distfile such as correction of typos, which are not important enough that users of the package should go to the trouble of upgrading. Build fixes which cause a package to become compilable where it was previously failing (as long as the changes do not introduce any functional change on any other platforms on which the port did previously build). Since PORTREVISION reflects the content of the package, if the package was not previously buildable then there is no need to increase PORTREVISION to mark a change. A rule of thumb is to ask yourself whether a change committed to a port is something which everyone would benefit from having (either because of an enhancement, fix, or by virtue that the new package will actually work at all), and weigh that against that fact that it will cause everyone who regularly updates their ports tree to be compelled to update. If yes, the PORTREVISION should be bumped. <varname>PORTEPOCH</varname> From time to time a software vendor or &os; porter will do something silly and release a version of their software which is actually numerically less than the previous version. An example of this is a port which goes from foo-20000801 to foo-1.0 (the former will be incorrectly treated as a newer version since 20000801 is a numerically greater value than 1). The results of version number comparisons are not always obvious. pkg version (see &man.pkg-version.8;) can be used to test the comparison of two version number strings. For example: &prompt.user; pkg version -t 0.031 0.29 > The > output indicates that version 0.031 is considered greater than version 0.29, which may not have been obvious to the porter. In situations such as this, the PORTEPOCH version should be increased. If PORTEPOCH is nonzero it is appended to the package name as described in section 0 above. PORTEPOCH must never be decreased or reset to zero, because that would cause comparison to a package from an earlier epoch to fail (i.e., the package would not be detected as out of date): the new version number (e.g., 1.0,1 in the above example) is still numerically less than the previous version (20000801), but the ,1 suffix is treated specially by automated tools and found to be greater than the implied suffix ,0 on the earlier package. Dropping or resetting PORTEPOCH incorrectly leads to no end of grief; if you do not understand the above discussion, please keep after it until you do, or ask questions on the mailing lists. It is expected that PORTEPOCH will not be used for the majority of ports, and that sensible use of PORTVERSION can often preempt it becoming necessary if a future release of the software should change the version structure. However, care is needed by &os; porters when a vendor release is made without an official version number — such as a code snapshot release. The temptation is to label the release with the release date, which will cause problems as in the example above when a new official release is made. For example, if a snapshot release is made on the date 20000917, and the previous version of the software was version 1.2, the snapshot release should be given a PORTVERSION of 1.2.20000917 or similar, not 20000917, so that the succeeding release, say 1.3, is still a numerically greater value. Example of <varname>PORTREVISION</varname> and <varname>PORTEPOCH</varname> Usage The gtkmumble port, version 0.10, is committed to the ports collection: PORTNAME= gtkmumble PORTVERSION= 0.10 PKGNAME becomes gtkmumble-0.10. A security hole is discovered which requires a local &os; patch. PORTREVISION is bumped accordingly. PORTNAME= gtkmumble PORTVERSION= 0.10 PORTREVISION= 1 PKGNAME becomes gtkmumble-0.10_1 A new version is released by the vendor, numbered 0.2 (it turns out the author actually intended 0.10 to actually mean 0.1.0, not what comes after 0.9 - oops, too late now). Since the new minor version 2 is numerically less than the previous version 10, the PORTEPOCH must be bumped to manually force the new package to be detected as newer. Since it is a new vendor release of the code, PORTREVISION is reset to 0 (or removed from the Makefile). PORTNAME= gtkmumble PORTVERSION= 0.2 PORTEPOCH= 1 PKGNAME becomes gtkmumble-0.2,1 The next release is 0.3. Since PORTEPOCH never decreases, the version variables are now: PORTNAME= gtkmumble PORTVERSION= 0.3 PORTEPOCH= 1 PKGNAME becomes gtkmumble-0.3,1 If PORTEPOCH were reset to 0 with this upgrade, someone who had installed the gtkmumble-0.10_1 package would not detect the gtkmumble-0.3 package as newer, since 3 is still numerically less than 10. Remember, this is the whole point of PORTEPOCH in the first place. <varname>PKGNAMEPREFIX</varname> and <varname>PKGNAMESUFFIX</varname> Two optional variables, PKGNAMEPREFIX and PKGNAMESUFFIX, are combined with PORTNAME and PORTVERSION to form PKGNAME as ${PKGNAMEPREFIX}${PORTNAME}${PKGNAMESUFFIX}-${PORTVERSION}. Make sure this conforms to our guidelines for a good package name. In particular, you are not allowed to use a hyphen (-) in PORTVERSION. Also, if the package name has the language- or the -compiled.specifics part (see below), use PKGNAMEPREFIX and PKGNAMESUFFIX, respectively. Do not make them part of PORTNAME. Package Naming Conventions These are the conventions to follow when naming packages. This is to make the package directory easy to scan, as there are already thousands of packages and users are going to turn away if they hurt their eyes! Package names take the form of language_region-name-compiled.specifics-version.numbers. The package name is defined as ${PKGNAMEPREFIX}${PORTNAME}${PKGNAMESUFFIX}-${PORTVERSION}. Make sure to set the variables to conform to that format. language_region- &os; strives to support the native language of its users. The language- part is a two letter abbreviation of the natural language defined by ISO-639 when the port is specific to a certain language. Examples are ja for Japanese, ru for Russian, vi for Vietnamese, zh for Chinese, ko for Korean and de for German. If the port is specific to a certain region within the language area, add the two letter country code as well. Examples are en_US for US English and fr_CH for Swiss French. The language- part is set in the PKGNAMEPREFIX variable. name The first letter of the name part should be lowercase. (The rest of the name may contain capital letters, so use your own discretion when converting a software name that has some capital letters in it.) There is a tradition of naming Perl 5 modules by prepending p5- and converting the double-colon separator to a hyphen. For example, the Data::Dumper module becomes p5-Data-Dumper. Make sure that the port's name and version are clearly separated and placed into the PORTNAME and PORTVERSION variables. The only reason for PORTNAME to contain a version part is if the upstream distribution is really named that way, as in the textproc/libxml2 or japanese/kinput2-freewnn ports. Otherwise, the PORTNAME should not contain any version-specific information. It is quite normal for several ports to have the same PORTNAME, as the www/apache* ports do; in that case, different versions (and different index entries) are distinguished by the PKGNAMEPREFIX and PKGNAMESUFFIX values. -compiled.specifics If the port can be built with different hardcoded defaults (usually part of the directory name in a family of ports), the -compiled.specifics part should state the compiled-in defaults (the hyphen is optional). Examples are paper size and font units. The -compiled.specifics part is set in the PKGNAMESUFFIX variable. -version.numbers The version string follows a dash (-) and is a period-separated list of integers and single lowercase alphabetics. In particular, it is not permissible to have another dash inside the version string. The only exception is the string pl (meaning patchlevel), which can be used only when there are no major and minor version numbers in the software. If the software version has strings like alpha, beta, rc, or pre, take the first letter and put it immediately after a period. If the version string continues after those names, the numbers should follow the single alphabet without an extra period between them. The idea is to make it easier to sort ports by looking at the version string. In particular, make sure version number components are always delimited by a period, and if the date is part of the string, use the 0.0.yyyy.mm.dd format, not dd.mm.yyyy or the non-Y2K compliant yy.mm.dd format. It is important to prefix the version with 0.0. in case a release with an actual version number is made, which would of course be numerically less than yyyy. Package name must be unique among all of the ports tree, check that there is not already a port with the same PORTNAME and if there is add one of PKGNAMEPREFIX or PKGNAMESUFFIX. Here are some (real) examples on how to convert the name as called by the software authors to a suitable package name: Distribution Name PKGNAMEPREFIX PORTNAME PKGNAMESUFFIX PORTVERSION Reason mule-2.2.2 (empty) mule (empty) 2.2.2 No changes required EmiClock-1.0.2 (empty) emiclock (empty) 1.0.2 No uppercase names for single programs rdist-1.3alpha (empty) rdist (empty) 1.3.a No strings like alpha allowed es-0.9-beta1 (empty) es (empty) 0.9.b1 No strings like beta allowed mailman-2.0rc3 (empty) mailman (empty) 2.0.r3 No strings like rc allowed v3.3beta021.src (empty) tiff (empty) 3.3 What the heck was that anyway? tvtwm (empty) tvtwm (empty) pl11 Version string always required piewm (empty) piewm (empty) 1.0 Version string always required xvgr-2.10pl1 (empty) xvgr (empty) 2.10.1 pl allowed only when no major/minor version numbers gawk-2.15.6 ja- gawk (empty) 2.15.6 Japanese language version psutils-1.13 (empty) psutils -letter 1.13 Paper size hardcoded at package build time pkfonts (empty) pkfonts 300 1.0 Package for 300dpi fonts If there is absolutely no trace of version information in the original source and it is unlikely that the original author will ever release another version, just set the version string to 1.0 (like the piewm example above). Otherwise, ask the original author or use the date string (0.0.yyyy.mm.dd) as the version. Categorization <varname>CATEGORIES</varname> When a package is created, it is put under /usr/ports/packages/All and links are made from one or more subdirectories of /usr/ports/packages. The names of these subdirectories are specified by the variable CATEGORIES. It is intended to make life easier for the user when he is wading through the pile of packages on the FTP site or the CDROM. Please take a look at the current list of categories and pick the ones that are suitable for your port. This list also determines where in the ports tree the port is imported. If you put more than one category here, it is assumed that the port files will be put in the subdirectory with the name in the first category. See below for more discussion about how to pick the right categories. Current List of Categories Here is the current list of port categories. Those marked with an asterisk (*) are virtual categories—those that do not have a corresponding subdirectory in the ports tree. They are only used as secondary categories, and only for search purposes. For non-virtual categories, you will find a one-line description in the COMMENT in that subdirectory's Makefile. Category Description Notes accessibility Ports to help disabled users. afterstep* Ports to support the AfterStep window manager. arabic Arabic language support. archivers Archiving tools. astro Astronomical ports. audio Sound support. benchmarks Benchmarking utilities. biology Biology-related software. cad Computer aided design tools. chinese Chinese language support. comms Communication software. Mostly software to talk to your serial port. converters Character code converters. databases Databases. deskutils Things that used to be on the desktop before computers were invented. devel Development utilities. Do not put libraries here just because they are libraries—unless they truly do not belong anywhere else, they should not be in this category. dns DNS-related software. docs* Meta-ports for &os; documentation. editors General editors. Specialized editors go in the section for those tools (e.g., a mathematical-formula editor will go in math). elisp* Emacs-lisp ports. emulators Emulators for other operating systems. Terminal emulators do not belong here—X-based ones should go to x11 and text-based ones to either comms or misc, depending on the exact functionality. finance Monetary, financial and related applications. french French language support. ftp FTP client and server utilities. If your port speaks both FTP and HTTP, put it in ftp with a secondary category of www. games Games. geography* Geography-related software. german German language support. gnome* Ports from the GNOME Project. gnustep* Software related to the GNUstep desktop environment. graphics Graphics utilities. hamradio* Software for amateur radio. haskell* Software related to the Haskell language. hebrew Hebrew language support. hungarian Hungarian language support. ipv6* IPv6 related software. irc Internet Relay Chat utilities. japanese Japanese language support. java Software related to the Java™ language. The java category must not be the only one for a port. Save for ports directly related to the Java language, porters are also encouraged not to use java as the main category of a port. kde* Ports from the KDE Project. kld* Kernel loadable modules. korean Korean language support. lang Programming languages. linux* Linux applications and support utilities. lisp* Software related to the Lisp language. mail Mail software. math Numerical computation software and other utilities for mathematics. mbone* MBone applications. misc Miscellaneous utilities Basically things that do not belong anywhere else. If at all possible, try to find a better category for your port than misc, as ports tend to get overlooked in here. multimedia Multimedia software. net Miscellaneous networking software. net-im Instant messaging software. net-mgmt Networking management software. net-p2p Peer to peer network applications. news USENET news software. palm Software support for the Palm™ series. parallel* Applications dealing with parallelism in computing. pear* Ports related to the Pear PHP framework. perl5* Ports that require Perl version 5 to run. plan9* Various programs from Plan9. polish Polish language support. ports-mgmt Ports for managing, installing and developing &os; ports and packages. portuguese Portuguese language support. print Printing software. Desktop publishing tools (previewers, etc.) belong here too. python* Software related to the Python language. ruby* Software related to the Ruby language. rubygems* Ports of RubyGems packages. russian Russian language support. scheme* Software related to the Scheme language. science Scientific ports that do not fit into other categories such as astro, biology and math. security Security utilities. shells Command line shells. spanish* Spanish language support. sysutils System utilities. tcl* Ports that use Tcl to run. textproc Text processing utilities. It does not include desktop publishing tools, which go to print. tk* Ports that use Tk to run. ukrainian Ukrainian language support. vietnamese Vietnamese language support. windowmaker* Ports to support the WindowMaker window manager. www Software related to the World Wide Web. HTML language support belongs here too. x11 The X Window System and friends. This category is only for software that directly supports the window system. Do not put regular X applications here; most of them should go into other x11-* categories (see below). x11-clocks X11 clocks. x11-drivers X11 drivers. x11-fm X11 file managers. x11-fonts X11 fonts and font utilities. x11-servers X11 servers. x11-themes X11 themes. x11-toolkits X11 toolkits. x11-wm X11 window managers. xfce* Ports related to the Xfce desktop environment. zope* Zope support. Choosing the Right Category As many of the categories overlap, you often have to choose which of the categories should be the primary category of your port. There are several rules that govern this issue. Here is the list of priorities, in decreasing order of precedence: The first category must be a physical category (see above). This is necessary to make the packaging work. Virtual categories and physical categories may be intermixed after that. Language specific categories always come first. For example, if your port installs Japanese X11 fonts, then your CATEGORIES line would read japanese x11-fonts. Specific categories are listed before less-specific ones. For instance, an HTML editor should be listed as www editors, not the other way around. Also, you should not list net when the port belongs to any of irc, mail, news, security, or www, as net is included implicitly. x11 is used as a secondary category only when the primary category is a natural language. In particular, you should not put x11 in the category line for X applications. Emacs modes should be placed in the same ports category as the application supported by the mode, not in editors. For example, an Emacs mode to edit source files of some programming language should go into lang. Ports which install loadable kernel modules should have the virtual category kld in their CATEGORIES line. This is one of the things handled automatically by adding kmod to the USES line. misc should not appear with any other non-virtual category. If you have misc with something else in your CATEGORIES line, that means you can safely delete misc and just put the port in that other subdirectory! If your port truly does not belong anywhere else, put it in misc. If you are not sure about the category, please put a comment to that effect in your &man.send-pr.1; submission so we can discuss it before we import it. If you are a committer, send a note to the &a.ports; so we can discuss it first. Too often, new ports are imported to the wrong category only to be moved right away. This causes unnecessary and undesirable bloat in the master source repository. Proposing a New Category As the Ports Collection has grown over time, various new categories have been introduced. New categories can either be virtual categories—those that do not have a corresponding subdirectory in the ports tree— or physical categories—those that do. The following text discusses the issues involved in creating a new physical category so that you can understand them before you propose one. Our existing practice has been to avoid creating a new physical category unless either a large number of ports would logically belong to it, or the ports that would belong to it are a logically distinct group that is of limited general interest (for instance, categories related to spoken human languages), or preferably both. The rationale for this is that such a change creates a fair amount of work for both the committers and also for all users who track changes to the Ports Collection. In addition, proposed category changes just naturally seem to attract controversy. (Perhaps this is because there is no clear consensus on when a category is too big, nor whether categories should lend themselves to browsing (and thus what number of categories would be an ideal number), and so forth.) Here is the procedure: Propose the new category on &a.ports;. You should include a detailed rationale for the new category, including why you feel the existing categories are not sufficient, and the list of existing ports proposed to move. (If there are new ports pending in GNATS that would fit this category, list them too.) If you are the maintainer and/or submitter, respectively, mention that as it may help you to make your case. Participate in the discussion. If it seems that there is support for your idea, file a PR which includes both the rationale and the list of existing ports that need to be moved. Ideally, this PR should also include patches for the following: Makefiles for the new ports once they are repocopied Makefile for the new category Makefile for the old ports' categories Makefiles for ports that depend on the old ports (for extra credit, you can include the other files that have to change, as per the procedure in the Committer's Guide.) Since it affects the ports infrastructure and involves not only performing repo-copies but also possibly running regression tests on the build cluster, the PR should be assigned to the &a.portmgr;. If that PR is approved, a committer will need to follow the rest of the procedure that is outlined in the Committer's Guide. Proposing a new virtual category should be similar to the above but much less involved, since no ports will actually have to move. In this case, the only patches to include in the PR would be those to add the new category to the CATEGORIES of the affected ports. Proposing Reorganizing All the Categories Occasionally someone proposes reorganizing the categories with either a 2-level structure, or some other kind of keyword structure. To date, nothing has come of any of these proposals because, while they are very easy to make, the effort involved to retrofit the entire existing ports collection with any kind of reorganization is daunting to say the very least. Please read the history of these proposals in the mailing list archives before you post this idea; furthermore, you should be prepared to be challenged to offer a working prototype. The Distribution Files The second part of the Makefile describes the files that must be downloaded in order to build the port, and where they can be downloaded from. <varname>DISTVERSION/DISTNAME</varname> DISTNAME is the name of the port as called by the authors of the software. DISTNAME defaults to ${PORTNAME}-${DISTVERSIONPREFIX}${DISTVERSION}${DISTVERSIONSUFFIX}, and DISTVERSION defaults to ${PORTVERSION} so override it only if necessary. DISTNAME is only used in two places. First, the distribution file list (DISTFILES) defaults to ${DISTNAME}${EXTRACT_SUFX}. Second, the distribution file is expected to extract into a subdirectory named WRKSRC, which defaults to work/${DISTNAME}. Some vendor's distribution names which do not fit into the ${PORTNAME}-${PORTVERSION}-scheme can be handled automatically by setting DISTVERSION. PORTVERSION will be derived from it automatically. Only one of PORTVERSION and DISTVERSION can be set at a time. If you set DISTVERSION and the derived PORTVERSION is not right, do not use DISTVERSION, set PORTVERSION to the right value and set DISTNAME with PORTNAME with either some computation of PORTVERSION or the verbatim upstream version. The following table lists some examples of DISTVERSION and the derived PORTVERSION: DISTVERSION PORTVERSION 0.7.1d 0.7.1.d 10Alpha3 10.a3 3Beta7-pre2 3.b7.p2 8:f_17 8f.17 PKGNAMEPREFIX and PKGNAMESUFFIX do not affect DISTNAME. Also note that if WRKSRC is equal to work/${DISTNAME} while the original source archive is named something other than ${PORTNAME}-${PORTVERSION}${EXTRACT_SUFX}, you should probably leave DISTNAME alone— you are better off defining DISTFILES than having to set both DISTNAME and WRKSRC (and possibly EXTRACT_SUFX). <varname>MASTER_SITES</varname> Record the directory part of the FTP/HTTP-URL pointing at the original tarball in MASTER_SITES. Do not forget the trailing slash (/)! The make macros will try to use this specification for grabbing the distribution file with FETCH if they cannot find it already on the system. It is recommended that you put multiple sites on this list, preferably from different continents. This will safeguard against wide-area network problems. We are even planning to add support for automatically determining the closest master site and fetching from there; having multiple sites will go a long way towards helping this effort. If the original tarball is part of one of the popular archives such as SourceForge, GNU, or Perl CPAN, you may be able refer to those sites in an easy compact form using predefined macros (e.g., SF, GNU or CPAN). Simply set MASTER_SITES to one of these values. Here is an example: MASTER_SITES= GNU/make Or you can use the older expanded format, though there really are no reason to do so: MASTER_SITES= ${MASTER_SITE_GNU} MASTER_SITE_SUBDIR= make These values and variables are defined in /usr/ports/Mk/bsd.sites.mk. There are new entries added all the time, so make sure to check the latest version of this file before submitting a port. Several magic macros exist for popular sites with a predictable directory structure. For these, just use the abbreviation and the system will try to guess the correct subdirectory for you. MASTER_SITES= SF If the guess is incorrect, it can be overridden as follows. MASTER_SITES= SF/stardict/WyabdcRealPeopleTTS/${PORTVERSION} This can also be written as MASTER_SITES= SF MASTER_SITE_SUBDIR= stardict/WyabdcRealPeopleTTS/${PORTVERSION} Popular Magic <varname>MASTER_SITES</varname> Macros Macro Assumed subdirectory APACHE_JAKARTA /dist/jakarta/${PORTNAME:S,-,,/,}/source BERLIOS /${PORTNAME:L} CHEESESHOP /packages/source/source/${DISTNAME:C/(.).*/\1/}/${DISTNAME:C/(.*)-[0-9].*/\1/} DEBIAN /debian/pool/main/${PORTNAME:C/^((lib)?.).*$/\1/}/${PORTNAME} GCC /pub/gcc/releases/${DISTNAME} GH /${GH_ACCOUNT}/${GH_PROJECT}/legacy.tar.gz/${GH_TAGNAME}?dummy=/ GHC /downloads/${GH_ACCOUNT}/${GH_PROJECT}/ GNOME /pub/GNOME/sources/${PORTNAME}/${PORTVERSION:C/^([0-9]+\.[0-9]+).*/\1/} GNU /gnu/${PORTNAME} HORDE /pub/${PORTNAME} LOGILAB /pub/${PORTNAME} MATE /releases/${PORTVERSION:C/^([0-9]+\.[0-9]+).*/\1/} MOZDEV /pub/mozdev/${PORTNAME:L} CPAN /pub/CPAN/modules/by-module/${PORTNAME:C/-.*//} PYTHON /ftp/python/${PYTHON_PORTVERSION:C/rc[0-9]//} RUBYFORGE /${PORTNAME:L} SAVANNAH /${PORTNAME:L} SF /project/${PORTNAME:L}/${PORTNAME:L}/${PORTVERSION}
<varname>USE_GITHUB</varname> If the distribution file comes from a specific commit or tag on GitHub for which there is no officially released file, there is an easy way to set the right DISTNAME and MASTER_SITES automatically. These variables are available: <varname>USE_GITHUB</varname> Description Variable Description Default Mandatory GH_ACCOUNT Account name of the GitHub user hosting the project none Mandatory GH_PROJECT Name of the project on GitHub ${PORTNAME} GH_TAGNAME Name of the tag to download (2.0.1, hash, ...) Using the name of a branch here is incorrect. It is possible to do GH_TAGNAME=${GH_COMMIT} to do a snapshot ${DISTVERSION} GH_COMMIT first 7 digits of the commit that generated GH_TAGNAME (see git-describe(1)) none Mandatory
Simple Use of <varname>USE_GITHUB</varname> While trying to make a port for version 1.2.7 of pkg from the &os; user on github, at , The Makefile would end up looking like this (slightly stripped for the example): PORTNAME= pkg PORTVERSION= 1.2.7 USE_GITHUB= yes GH_ACCOUNT= freebsd GH_COMMIT= f53e577 It will automatically have MASTER_SITES set to GH GHC and WRKSRC to ${WRKDIR}/freebsd-pkg-f53e577. More Complete Use of <varname>USE_GITHUB</varname> While trying to make a port for the bleeding edge version of pkg from the &os; user on github, at , The Makefile would end up looking like this (slightly stripped for the example): PORTNAME= pkg-devel PORTVERSION= 1.3.0.a.20140411 USE_GITHUB= yes GH_ACCOUNT= freebsd GH_PROJECT= pkg GH_TAGNAME= ${GH_COMMIT} GH_COMMIT= 6dbb17b It will automatically have MASTER_SITES set to GH GHC and WRKSRC to ${WRKDIR}/freebsd-pkg-6dbb17b. <varname>EXTRACT_SUFX</varname> If you have one distribution file, and it uses an odd suffix to indicate the compression mechanism, set EXTRACT_SUFX. For example, if the distribution file was named foo.tar.gzip instead of the more normal foo.tar.gz, you would write: DISTNAME= foo EXTRACT_SUFX= .tar.gzip The USES=tar[:xxx], USES=lha or USES=zip automatically set EXTRACT_SUFX to the most common archives extensions as necessary, see for more details. If neither of these are set then EXTRACT_SUFX defaults to .tar.gz. You never need to set both EXTRACT_SUFX and DISTFILES. <varname>DISTFILES</varname> Sometimes the names of the files to be downloaded have no resemblance to the name of the port. For example, it might be called source.tar.gz or similar. In other cases the application's source code might be in several different archives, all of which must be downloaded. If this is the case, set DISTFILES to be a space separated list of all the files that must be downloaded. DISTFILES= source1.tar.gz source2.tar.gz If not explicitly set, DISTFILES defaults to ${DISTNAME}${EXTRACT_SUFX}. <varname>EXTRACT_ONLY</varname> If only some of the DISTFILES must be extracted—for example, one of them is the source code, while another is an uncompressed document—list the filenames that must be extracted in EXTRACT_ONLY. DISTFILES= source.tar.gz manual.html EXTRACT_ONLY= source.tar.gz If none of the DISTFILES should be uncompressed then set EXTRACT_ONLY to the empty string. EXTRACT_ONLY= <varname>PATCHFILES</varname> If your port requires some additional patches that are available by FTP or HTTP, set PATCHFILES to the names of the files and PATCH_SITES to the URL of the directory that contains them (the format is the same as MASTER_SITES). If the patch is not relative to the top of the source tree (i.e., WRKSRC) because it contains some extra pathnames, set PATCH_DIST_STRIP accordingly. For instance, if all the pathnames in the patch have an extra foozolix-1.0/ in front of the filenames, then set PATCH_DIST_STRIP=-p1. Do not worry if the patches are compressed; they will be decompressed automatically if the filenames end with .Z, .gz, .bz2 or .xz. If the patch is distributed with some other files, such as documentation, in a gzipped tarball, you cannot just use PATCHFILES. If that is the case, add the name and the location of the patch tarball to DISTFILES and MASTER_SITES. Then, use the EXTRA_PATCHES variable to point to those files and bsd.port.mk will automatically apply them for you. In particular, do not copy patch files into the PATCHDIR directory—that directory may not be writable. If there are multiple patches and they need mixed values for the strip parameter, it can be added alongside the patch name in PATCHFILES, e.g: PATCHFILES= patch1 patch2:-p1 This does not conflict with the master site grouping feature, the following also works: PATCHFILES= patch2:-p1:source2 The tarball will have been extracted alongside the regular source by then, so there is no need to explicitly extract it if it is a regular gzipped or compressed tarball. If you do the latter, take extra care not to overwrite something that already exists in that directory. Also, do not forget to add a command to remove the copied patch in the pre-clean target. Multiple Distribution Files or Patches from Different Sites and Subdirectories (<literal>MASTER_SITES:n</literal>) (Consider this to be a somewhat advanced topic; those new to this document may wish to skip this section at first). This section has information on the fetching mechanism known as both MASTER_SITES:n and MASTER_SITES_NN. We will refer to this mechanism as MASTER_SITES:n. A little background first. OpenBSD has a neat feature inside the DISTFILES and PATCHFILES variables which allows files and patches to be postfixed with :n identifiers. Here, n can be both [0-9] and denote a group designation. For example: DISTFILES= alpha:0 beta:1 In OpenBSD, distribution file alpha will be associated with variable MASTER_SITES0 instead of our common MASTER_SITES and beta with MASTER_SITES1. This is a very interesting feature which can decrease that endless search for the correct download site. Just picture 2 files in DISTFILES and 20 sites in MASTER_SITES, the sites slow as hell where beta is carried by all sites in MASTER_SITES, and alpha can only be found in the 20th site. It would be such a waste to check all of them if the maintainer knew this beforehand, would it not? Not a good start for that lovely weekend! Now that you have the idea, just imagine more DISTFILES and more MASTER_SITES. Surely our distfiles survey meister would appreciate the relief to network strain that this would bring. In the next sections, information will follow on the &os; implementation of this idea. We improved a bit on OpenBSD's concept. Simplified Information This section tells you how to quickly prepare fine grained fetching of multiple distribution files and patches from different sites and subdirectories. We describe here a case of simplified MASTER_SITES:n usage. This will be sufficient for most scenarios. However, if you need further information, you will have to refer to the next section. Some applications consist of multiple distribution files that must be downloaded from a number of different sites. For example, Ghostscript consists of the core of the program, and then a large number of driver files that are used depending on the user's printer. Some of these driver files are supplied with the core, but many others must be downloaded from a variety of different sites. To support this, each entry in DISTFILES may be followed by a colon and a tag name. Each site listed in MASTER_SITES is then followed by a colon, and the tag that indicates which distribution files should be downloaded from this site. For example, consider an application with the source split in two parts, source1.tar.gz and source2.tar.gz, which must be downloaded from two different sites. The port's Makefile would include lines like . Simplified Use of <literal>MASTER_SITES:n</literal> with One File Per Site MASTER_SITES= ftp://ftp.example1.com/:source1 \ ftp://ftp.example2.com/:source2 DISTFILES= source1.tar.gz:source1 \ source2.tar.gz:source2 Multiple distribution files can have the same tag. Continuing the previous example, suppose that there was a third distfile, source3.tar.gz, that should be downloaded from ftp.example2.com. The Makefile would then be written like . Simplified Use of <literal>MASTER_SITES:n</literal> with More Than One File Per Site MASTER_SITES= ftp://ftp.example1.com/:source1 \ ftp://ftp.example2.com/:source2 DISTFILES= source1.tar.gz:source1 \ source2.tar.gz:source2 \ source3.tar.gz:source2 Detailed Information Okay, so the previous section example did not reflect your needs? In this section we will explain in detail how the fine grained fetching mechanism MASTER_SITES:n works and how you can modify your ports to use it. Elements can be postfixed with :n where n is [^:,]+, i.e., n could conceptually be any alphanumeric string but we will limit it to [a-zA-Z_][0-9a-zA-Z_]+ for now. Moreover, string matching is case sensitive; i.e., n is different from N. However, the following words cannot be used for postfixing purposes since they yield special meaning: default, all and ALL (they are used internally in item ). Furthermore, DEFAULT is a special purpose word (check item ). Elements postfixed with :n belong to the group n, :m belong to group m and so forth. Elements without a postfix are groupless, i.e., they all belong to the special group DEFAULT. If you postfix any elements with DEFAULT, you are just being redundant unless you want to have an element belonging to both DEFAULT and other groups at the same time (check item ). The following examples are equivalent but the first one is preferred: MASTER_SITES= alpha MASTER_SITES= alpha:DEFAULT Groups are not exclusive, an element may belong to several different groups at the same time and a group can either have either several different elements or none at all. Repeated elements within the same group will be simply that, repeated elements. When you want an element to belong to several groups at the same time, you can use the comma operator (,). Instead of repeating it several times, each time with a different postfix, we can list several groups at once in a single postfix. For instance, :m,n,o marks an element that belongs to group m, n and o. All the following examples are equivalent but the last one is preferred: MASTER_SITES= alpha alpha:SOME_SITE MASTER_SITES= alpha:DEFAULT alpha:SOME_SITE MASTER_SITES= alpha:SOME_SITE,DEFAULT MASTER_SITES= alpha:DEFAULT,SOME_SITE All sites within a given group are sorted according to MASTER_SORT_AWK. All groups within MASTER_SITES and PATCH_SITES are sorted as well. Group semantics can be used in any of the following variables MASTER_SITES, PATCH_SITES, MASTER_SITE_SUBDIR, PATCH_SITE_SUBDIR, DISTFILES, and PATCHFILES according to the following syntax: All MASTER_SITES, PATCH_SITES, MASTER_SITE_SUBDIR and PATCH_SITE_SUBDIR elements must be terminated with the forward slash / character. If any elements belong to any groups, the group postfix :n must come right after the terminator /. The MASTER_SITES:n mechanism relies on the existence of the terminator / to avoid confusing elements where a :n is a valid part of the element with occurrences where :n denotes group n. For compatibility purposes, since the / terminator was not required before in both MASTER_SITE_SUBDIR and PATCH_SITE_SUBDIR elements, if the postfix immediate preceding character is not a / then :n will be considered a valid part of the element instead of a group postfix even if an element is postfixed with :n. See both and . Detailed Use of <literal>MASTER_SITES:n</literal> in <varname>MASTER_SITE_SUBDIR</varname> MASTER_SITE_SUBDIR= old:n new/:NEW Directories within group DEFAULT -> old:n Directories within group NEW -> new Detailed Use of <literal>MASTER_SITES:n</literal> with Comma Operator, Multiple Files, Multiple Sites and Multiple Subdirectories MASTER_SITES= http://site1/%SUBDIR%/ http://site2/:DEFAULT \ http://site3/:group3 http://site4/:group4 \ http://site5/:group5 http://site6/:group6 \ http://site7/:DEFAULT,group6 \ http://site8/%SUBDIR%/:group6,group7 \ http://site9/:group8 DISTFILES= file1 file2:DEFAULT file3:group3 \ file4:group4,group5,group6 file5:grouping \ file6:group7 MASTER_SITE_SUBDIR= directory-trial:1 directory-n/:groupn \ directory-one/:group6,DEFAULT \ directory The previous example results in the following fine grained fetching. Sites are listed in the exact order they will be used. file1 will be fetched from MASTER_SITE_OVERRIDE http://site1/directory-trial:1/ http://site1/directory-one/ http://site1/directory/ http://site2/ http://site7/ MASTER_SITE_BACKUP file2 will be fetched exactly as file1 since they both belong to the same group MASTER_SITE_OVERRIDE http://site1/directory-trial:1/ http://site1/directory-one/ http://site1/directory/ http://site2/ http://site7/ MASTER_SITE_BACKUP file3 will be fetched from MASTER_SITE_OVERRIDE http://site3/ MASTER_SITE_BACKUP file4 will be fetched from MASTER_SITE_OVERRIDE http://site4/ http://site5/ http://site6/ http://site7/ http://site8/directory-one/ MASTER_SITE_BACKUP file5 will be fetched from MASTER_SITE_OVERRIDE MASTER_SITE_BACKUP file6 will be fetched from MASTER_SITE_OVERRIDE http://site8/ MASTER_SITE_BACKUP How do I group one of the special variables from bsd.sites.mk, e.g., MASTER_SITE_SOURCEFORGE? See . Detailed Use of <literal>MASTER_SITES:n</literal> with <varname>MASTER_SITE_SOURCEFORGE</varname> MASTER_SITES= http://site1/ ${MASTER_SITE_SOURCEFORGE:S/$/:sourceforge,TEST/} DISTFILES= something.tar.gz:sourceforge something.tar.gz will be fetched from all sites within MASTER_SITE_SOURCEFORGE. How do I use this with PATCH* variables? All examples were done with MASTER* variables but they work exactly the same for PATCH* ones as can be seen in . Simplified Use of <literal>MASTER_SITES:n</literal> with <varname>PATCH_SITES</varname> PATCH_SITES= http://site1/ http://site2/:test PATCHFILES= patch1:test What Does Change for Ports? What Does Not? All current ports remain the same. The MASTER_SITES:n feature code is only activated if there are elements postfixed with :n like elements according to the aforementioned syntax rules, especially as shown in item . The port targets remain the same: checksum, makesum, patch, configure, build, etc. With the obvious exceptions of do-fetch, fetch-list, master-sites and patch-sites. do-fetch: deploys the new grouping postfixed DISTFILES and PATCHFILES with their matching group elements within both MASTER_SITES and PATCH_SITES which use matching group elements within both MASTER_SITE_SUBDIR and PATCH_SITE_SUBDIR. Check . fetch-list: works like old fetch-list with the exception that it groups just like do-fetch. master-sites and patch-sites: (incompatible with older versions) only return the elements of group DEFAULT; in fact, they execute targets master-sites-default and patch-sites-default respectively. Furthermore, using target either master-sites-all or patch-sites-all is preferred to directly checking either MASTER_SITES or PATCH_SITES. Also, directly checking is not guaranteed to work in any future versions. Check item for more information on these new port targets. New port targets There are master-sites-n and patch-sites-n targets which will list the elements of the respective group n within MASTER_SITES and PATCH_SITES respectively. For instance, both master-sites-DEFAULT and patch-sites-DEFAULT will return the elements of group DEFAULT, master-sites-test and patch-sites-test of group test, and thereon. There are new targets master-sites-all and patch-sites-all which do the work of the old master-sites and patch-sites ones. They return the elements of all groups as if they all belonged to the same group with the caveat that it lists as many MASTER_SITE_BACKUP and MASTER_SITE_OVERRIDE as there are groups defined within either DISTFILES or PATCHFILES; respectively for master-sites-all and patch-sites-all. <varname>DIST_SUBDIR</varname> Do not let your port clutter /usr/ports/distfiles. If your port requires a lot of files to be fetched, or contains a file that has a name that might conflict with other ports (e.g., Makefile), set DIST_SUBDIR to the name of the port (${PORTNAME} or ${PKGNAMEPREFIX}${PORTNAME} should work fine). This will change DISTDIR from the default /usr/ports/distfiles to /usr/ports/distfiles/DIST_SUBDIR, and in effect puts everything that is required for your port into that subdirectory. It will also look at the subdirectory with the same name on the backup master site at ftp.FreeBSD.org. (Setting DISTDIR explicitly in your Makefile will not accomplish this, so please use DIST_SUBDIR.) This does not affect the MASTER_SITES you define in your Makefile. <varname>ALWAYS_KEEP_DISTFILES</varname> If your port uses binary distfiles and has a license that requires that the source code is provided with packages distributed in binary form, e.g., GPL, ALWAYS_KEEP_DISTFILES will instruct the &os; build cluster to keep a copy of the files specified in DISTFILES. Users of these ports will generally not need these files, so it is a good idea to only add the source distfiles to DISTFILES when PACKAGE_BUILDING is defined. Use of <varname>ALWAYS_KEEP_DISTFILES</varname> .if defined(PACKAGE_BUILDING) DISTFILES+= foo.tar.gz ALWAYS_KEEP_DISTFILES= yes .endif When adding extra files to DISTFILES, make sure you also add them to distinfo. Also, the additional files will normally be extracted into WRKDIR as well, which for some ports may lead to undesirable side effects and require special handling. <varname>MAINTAINER</varname> Set your mail-address here. Please. :-) Only a single address without the comment part is allowed as a MAINTAINER value. The format used is user@hostname.domain. Please do not include any descriptive text such as a real name in this entry. That merely confuses the Ports infrastructure and most tools using it. The maintainer is responsible for keeping the port up to date and making sure that it works correctly. For a detailed description of the responsibilities of a port maintainer, refer to The challenge for port maintainers. A maintainer volunteers to keep a port in good working order. Maintainers have the primary responsibility for their ports, but not exclusive ownership. Ports exist for the benefit of the community and, in reality, belong to the community. What this means is that people other than the maintainer can make changes to a port. Large changes to the Ports Collection might require changes to many ports. The &os; Ports Management Team or members of other teams might modify ports to fix dependency issues or other problems, like a version bump for a shared library update. Some types of fixes have blanket approval from the &a.portmgr;, allowing any committer to fix those categories of problems on any port. These fixes do not need approval from the maintainer. Blanket approval does not apply to ports that are maintained by teams like autotools@FreeBSD.org, x11@FreeBSD.org, gnome@FreeBSD.org, or kde@FreeBSD.org. These teams use external repositories and can have work that would conflict with changes that would normally fall under blanket approval. Blanket approval for most ports applies to these types of fixes: Most infrastructure changes to a port (that is, modernizing, but not changing the functionality). For example, converting to staging, USE_GMAKE to USES=gmake, the new LIB_DEPENDS format... Trivial and tested build fixes. Other changes to the port will be sent to the maintainer for review and approval before being committed. If the maintainer does not respond to an update request after two weeks (excluding major public holidays), then that is considered a maintainer timeout, and the update may be made without explicit maintainer approval. If the maintainer does not respond within three months, then that maintainer is considered absent without leave, and can be replaced as the maintainer of the particular port in question. Exceptions to this are anything maintained by the &a.portmgr;, or the &a.security-officer;. No unauthorized commits may ever be made to ports maintained by those groups. We reserve the right to modify the maintainer's submission to better match existing policies and style of the Ports Collection without explicit blessing from the submitter or the maintainer. Also, large infrastructural changes can result in a port being modified without the maintainer's consent. These kinds of changes will never affect the port's functionality. The &a.portmgr; reserves the right to revoke or override anyone's maintainership for any reason, and the &a.security-officer; reserves the right to revoke or override maintainership for security reasons. <varname>COMMENT</varname> This is a one-line description of the port. Please respect the following rules: Try to keep the COMMENT value at no longer than 70 characters, as this line will be used by pkg info (see &man.pkg-info.8;) to display a one-line summary of the port; Do not include the package name (or version number of the software); The comment should begin with a capital and end without a period; Do not start with an indefinite article (i.e., A or An); Names are capitalized (for example, Apache, JavaScript, Perl); For lists of words, use the Oxford comma (e.g., green, red, and blue); Spell check the text. Here is an example: COMMENT= Cat chasing a mouse all over the screen The COMMENT variable should immediately follow the MAINTAINER variable in the Makefile. <varname>PORTSCOUT</varname> Portscout is an automated distfile check utility for the &os; Ports Collection, described in detail in . The PORTSCOUT variable defines special conditions within which the Portscout distfile scanner should be restricted. Situations where the PORTSCOUT variable should be set include: When distfiles should be ignored, whether for specific versions, or specific minor revisions. For example, to exclude version 8.2 from distfile version checks because it is known to be broken, add: PORTSCOUT= ignore:8.2 When specific versions or specific major and minor revisions of a distfile should be checked. For example, if only version 0.6.4 should be monitored because newer versions have compatibility issues with &os;, add: PORTSCOUT= limit:^0\.6\.4 When URLs listing the available versions differ from the download URLs. For example, to limit distfile version checks to the download page for the databases/pgtune port, add: PORTSCOUT= site:http://pgfoundry.org/frs/?group_id=1000416 Dependencies Many ports depend on other ports. This is a very convenient feature of most Unix-like operating systems, including &os;. Multiple ports can share a common dependency, rather than bundling that dependency with every port or package that needs it. There are seven variables that can be used to ensure that all the required bits will be on the user's machine. There are also some pre-supported dependency variables for common cases, plus a few more to control the behavior of dependencies. <varname>LIB_DEPENDS</varname> This variable specifies the shared libraries this port depends on. It is a list of lib:dir tuples where lib is the name of the shared library, dir is the directory in which to find it in case it is not available. For example, LIB_DEPENDS= libjpeg.so:${PORTSDIR}/graphics/jpeg will check for a shared jpeg library with any version, and descend into the graphics/jpeg subdirectory of your ports tree to build and install it if it is not found. The dependency is checked twice, once from within the build target and then from within the install target. Also, the name of the dependency is put into the package so that pkg install (see &man.pkg-install.8;) will automatically install it if it is not on the user's system. <varname>RUN_DEPENDS</varname> This variable specifies executables or files this port depends on during run-time. It is a list of path:dir:target tuples where path is the name of the executable or file, dir is the directory in which to find it in case it is not available, and target is the target to call in that directory. If path starts with a slash (/), it is treated as a file and its existence is tested with test -e; otherwise, it is assumed to be an executable, and which -s is used to determine if the program exists in the search path. For example, RUN_DEPENDS= ${LOCALBASE}/news/bin/innd:${PORTSDIR}/news/inn \ xmlcatmgr:${PORTSDIR}/textproc/xmlcatmgr will check if the file or directory /usr/local/news/bin/innd exists, and build and install it from the news/inn subdirectory of the ports tree if it is not found. It will also see if an executable called xmlcatmgr is in the search path, and descend into the textproc/xmlcatmgr subdirectory of your ports tree to build and install it if it is not found. In this case, innd is actually an executable; if an executable is in a place that is not expected to be in the search path, you should use the full pathname. The official search PATH used on the ports build cluster is /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin The dependency is checked from within the install target. Also, the name of the dependency is put into the package so that pkg install (see &man.pkg-install.8;) will automatically install it if it is not on the user's system. The target part can be omitted if it is the same as DEPENDS_TARGET. A quite common situation is when RUN_DEPENDS is literally the same as BUILD_DEPENDS, especially if ported software is written in a scripted language or if it requires the same build and run-time environment. In this case, it is both tempting and intuitive to directly assign one to the other: RUN_DEPENDS= ${BUILD_DEPENDS} However, such assignment can pollute run-time dependencies with entries not defined in the port's original BUILD_DEPENDS. This happens because of &man.make.1;'s lazy evaluation of variable assignment. Consider a Makefile with USE_* variables, which are processed by ports/Mk/bsd.*.mk to augment initial build dependencies. For example, USES= gmake adds devel/gmake to BUILD_DEPENDS. To prevent such additional dependencies from polluting RUN_DEPENDS, take care to assign with expansion, i.e., expand the value before assigning it to the variable: RUN_DEPENDS:= ${BUILD_DEPENDS} <varname>BUILD_DEPENDS</varname> This variable specifies executables or files this port requires to build. Like RUN_DEPENDS, it is a list of path:dir:target tuples. For example, BUILD_DEPENDS= unzip:${PORTSDIR}/archivers/unzip will check for an executable called unzip, and descend into the archivers/unzip subdirectory of your ports tree to build and install it if it is not found. build here means everything from extraction to compilation. The dependency is checked from within the extract target. The target part can be omitted if it is the same as DEPENDS_TARGET <varname>FETCH_DEPENDS</varname> This variable specifies executables or files this port requires to fetch. Like the previous two, it is a list of path:dir:target tuples. For example, FETCH_DEPENDS= ncftp2:${PORTSDIR}/net/ncftp2 will check for an executable called ncftp2, and descend into the net/ncftp2 subdirectory of your ports tree to build and install it if it is not found. The dependency is checked from within the fetch target. The target part can be omitted if it is the same as DEPENDS_TARGET. <varname>EXTRACT_DEPENDS</varname> This variable specifies executables or files this port requires for extraction. Like the previous, it is a list of path:dir:target tuples. For example, EXTRACT_DEPENDS= unzip:${PORTSDIR}/archivers/unzip will check for an executable called unzip, and descend into the archivers/unzip subdirectory of your ports tree to build and install it if it is not found. The dependency is checked from within the extract target. The target part can be omitted if it is the same as DEPENDS_TARGET. Use this variable only if the extraction does not already work (the default assumes tar) and cannot be made to work using USES=tar, USES=lha or USES=zip described in . <varname>PATCH_DEPENDS</varname> This variable specifies executables or files this port requires to patch. Like the previous, it is a list of path:dir:target tuples. For example, PATCH_DEPENDS= ${NONEXISTENT}:${PORTSDIR}/java/jfc:extract will descend into the java/jfc subdirectory of your ports tree to extract it. The dependency is checked from within the patch target. The target part can be omitted if it is the same as DEPENDS_TARGET. <varname>USES</varname> Parameters can be added to define different features and dependencies used by the port. They are specified by adding this line to the Makefile: USES= feature[:arguments] For the complete list of values, please see . USES cannot be assigned after inclusion of bsd.port.pre.mk. <varname>USE_<replaceable>*</replaceable></varname> Several variables exist to define common dependencies shared by many ports. Their use is optional, but helps to reduce the verbosity of the port Makefiles. Each of them is styled as USE_*. These variables may be used only in the port Makefiles and ports/Mk/bsd.*.mk. They are not meant for user-settable options — use PORT_OPTIONS for that purpose. It is always incorrect to set any USE_* in /etc/make.conf. For instance, setting USE_GCC=X.Y (where X.Y is version number) would add a dependency on gccXY for every port, including lang/gccXY itself! The <varname>USE_<replaceable>*</replaceable></varname> Variables Variable Means USE_GCC The port requires GCC (gcc or g++) to build. Some ports need any GCC version, some require modern, recent versions. It is typically set to any (in this case, GCC from base would be used on versions of &os; that still have it, or lang/gcc port would be installed when default C/C++ compiler is Clang); or yes (means always use stable, modern GCC from lang/gcc port). The exact version can also be specified, with a value such as 4.7. The minimal required version can be specified as 4.6+. The GCC from the base system is used when it satisfies the requested version, otherwise an appropriate compiler in built from the port, and the CC and CXX variables are adjusted accordingly.
Variables related to gmake and the configure script are described in , while autoconf, automake and libtool are described in . Perl related variables are described in . X11 variables are listed in . deals with GNOME and with KDE related variables. documents Java variables, while contains information on Apache, PHP and PEAR modules. Python is discussed in , while Ruby in . provides variables used for SDL applications and finally, contains information on Xfce. Minimal Version of a Dependency A minimal version of a dependency can be specified in any *_DEPENDS variable except LIB_DEPENDS using the following syntax: p5-Spiffy>=0.26:${PORTSDIR}/devel/p5-Spiffy The first field contains a dependent package name, which must match the entry in the package database, a comparison sign, and a package version. The dependency is satisfied if p5-Spiffy-0.26 or newer is installed on the machine. Notes on Dependencies As mentioned above, the default target to call when a dependency is required is DEPENDS_TARGET. It defaults to install. This is a user variable; it is never defined in a port's Makefile. If your port needs a special way to handle a dependency, use the :target part of the *_DEPENDS variables instead of redefining DEPENDS_TARGET. When you type make clean, its dependencies are automatically cleaned too. If you do not wish this to happen, define the variable NOCLEANDEPENDS in your environment. This may be particularly desirable if the port has something that takes a long time to rebuild in its dependency list, such as KDE, GNOME or Mozilla. To depend on another port unconditionally, use the variable ${NONEXISTENT} as the first field of BUILD_DEPENDS or RUN_DEPENDS. Use this only when you need to get the source of the other port. You can often save compilation time by specifying the target too. For instance BUILD_DEPENDS= ${NONEXISTENT}:${PORTSDIR}/graphics/jpeg:extract will always descend to the jpeg port and extract it. Circular Dependencies Are Fatal Do not introduce any circular dependencies into the ports tree! The ports building technology does not tolerate circular dependencies. If you introduce one, you will have someone, somewhere in the world, whose &os; installation will break almost immediately, with many others quickly to follow. These can really be hard to detect; if in doubt, before you make that change, make sure you have done the following: cd /usr/ports; make index. That process can be quite slow on older machines, but you may be able to save a large number of people—including yourself— a lot of grief in the process. Problems Caused by Automatic Dependencies Dependencies must be declared either explicitly or by using the OPTIONS framework. Using other methods like automatic detection complicates indexing, which causes problems for port and package management. Wrong Declaration of an Optional Dependency .include <bsd.port.pre.mk> .if exists(${LOCALBASE}/bin/foo) LIB_DEPENDS= libbar.so:${PORTSDIR}/foo/bar .endif The problem with trying to automatically add dependencies is that files and settings outside an individual port can change at any time. For example: an index is built, then a batch of ports are installed. But one of the ports installs the tested file. The index is now incorrect, because an installed port unexpectedly has a new dependency. The index may still be wrong even after rebuilding if other ports also determine their need for dependencies based on the existence of other files. Correct Declaration of an Optional Dependency OPTIONS_DEFINE= BAR BAR_DESC= Calling cellphones via bar BAR_LIB_DEPENDS= libbar.so:${PORTSDIR}/foo/bar Testing option variables is the correct method. It will not cause inconsistencies in the index of a batch of ports, provided the options were defined prior to the index build. Simple scripts can then be used to automate the building, installation, and updating of these ports and their packages. <varname>USE_</varname> and <varname>WANT_</varname> USE_ variables are set by the port maintainer to define software on which this port depends. A port that needs Firefox would set USE_FIREFOX= yes Some USE_ variables can accept version numbers or other parameters. For example, a port that requires Apache 2.2 would set USE_APACHE= 22 For more control over dependencies in some cases, WANT_ variables are available to more precisely specify what is needed. For example, consider the mail/squirrelmail port. This port needs some PHP modules, which are listed in the USE_PHP variable: USE_PHP= session mhash gettext mbstring pcre openssl xml Those modules may be available in CLI or web versions, so the web version is selected with a WANT_ variable: WANT_PHP_WEB= yes Available USE_ and WANT_ variables are defined in the files in /usr/ports/Mk. <varname>MASTERDIR</varname> If your port needs to build slightly different versions of packages by having a variable (for instance, resolution, or paper size) take different values, create one subdirectory per package to make it easier for users to see what to do, but try to share as many files as possible between ports. Typically you only need a very short Makefile in all but one of the directories if you use variables cleverly. In the sole Makefile, you can use MASTERDIR to specify the directory where the rest of the files are. Also, use a variable as part of PKGNAMESUFFIX so the packages will have different names. This will be best demonstrated by an example. This is part of japanese/xdvi300/Makefile; PORTNAME= xdvi PORTVERSION= 17 PKGNAMEPREFIX= ja- PKGNAMESUFFIX= ${RESOLUTION} : # default RESOLUTION?= 300 .if ${RESOLUTION} != 118 && ${RESOLUTION} != 240 && \ ${RESOLUTION} != 300 && ${RESOLUTION} != 400 @${ECHO_MSG} "Error: invalid value for RESOLUTION: \"${RESOLUTION}\"" @${ECHO_MSG} "Possible values are: 118, 240, 300 (default) and 400." @${FALSE} .endif japanese/xdvi300 also has all the regular patches, package files, etc. If you type make there, it will take the default value for the resolution (300) and build the port normally. As for other resolutions, this is the entire xdvi118/Makefile: RESOLUTION= 118 MASTERDIR= ${.CURDIR}/../xdvi300 .include "${MASTERDIR}/Makefile" (xdvi240/Makefile and xdvi400/Makefile are similar). The MASTERDIR definition tells bsd.port.mk that the regular set of subdirectories like FILESDIR and SCRIPTDIR are to be found under xdvi300. The RESOLUTION=118 line will override the RESOLUTION=300 line in xdvi300/Makefile and the port will be built with resolution set to 118. Man Pages If your port anchors its man tree somewhere other than PREFIX, you can use MANDIRS to specify those directories. Note that the files corresponding to manual pages should be placed in pkg-plist along with the rest of the files. The purpose of MANDIRS is to enable automatic compression of manual pages, therefore the file names should be suffixed with .gz. Info Files If your package needs to install GNU info files, they should be listed in the INFO variable (without the trailing .info), one entry per document. These files are assumed to be installed to PREFIX/INFO_PATH. You can change INFO_PATH if your package uses a different location. However, this is not recommended. These entries contain just the path relative to PREFIX/INFO_PATH. For example, lang/gcc34 installs info files to PREFIX/INFO_PATH/gcc34, and INFO will be something like this: INFO= gcc34/cpp gcc34/cppinternals gcc34/g77 ... Appropriate installation/de-installation code will be automatically added to the temporary pkg-plist before package registration. Makefile Options Many applications can be built with optional or differing configurations. Examples include choice of natural (human) language, GUI versus command-line, or type of database to support. Users may need a different configuration than the default, so the ports system provides hooks the port author can use to control which variant will be built. Supporting these options properly will make users happy, and effectively provide two or more ports for the price of one. <varname>OPTIONS</varname> Background The OPTIONS_* variables give the user installing the port a dialog showing the available options, and then saves those options to /var/db/ports/${UNIQUENAME}/options. The next time the port is built, the options are reused. When the user runs make config (or runs make build for the first time), the framework checks for /var/db/ports/${UNIQUENAME}/options. If that file does not exist, the values of OPTIONS_* are used, and a dialog box is displayed where the options can be enabled or disabled. Then the options file is saved and the configured variables are used when building the port. If a new version of the port adds new OPTIONS, the dialog will be presented to the user with the saved values of old OPTIONS prefilled. make showconfig shows the saved configuration. Use make rmconfig to remove the saved configuration. Syntax OPTIONS_DEFINE contains a list of OPTIONS to be used. These are independent of each other and are not grouped: OPTIONS_DEFINE= OPT1 OPT2 Once defined, OPTIONS are described (optional, but strongly recommended): OPT1_DESC= Describe OPT1 OPT2_DESC= Describe OPT2 OPT3_DESC= Describe OPT3 OPT4_DESC= Describe OPT4 OPT5_DESC= Describe OPT5 OPT6_DESC= Describe OPT6 ports/Mk/bsd.options.desc.mk has descriptions for many common OPTIONS. While often useful, they should be overridden if the description is insufficient for the port. When describing options, view it from the perspective of the user: What functionality does it change? and Why would I want to enable this? Do not just repeat the name. For example, describing the NLS option as include NLS support does not help the user, who can already see the option name but may not know what it means. Describing it as Native Language Support via gettext utilities is much more helpful. Option names should always be in all uppercase. They should not use mixed case or lowercase. OPTIONS can be grouped as radio choices, where only one choice from each group is allowed: OPTIONS_SINGLE= SG1 OPTIONS_SINGLE_SG1= OPT3 OPT4 OPTIONS can be grouped as radio choices, where none or only one choice from each group is allowed: OPTIONS_RADIO= RG1 OPTIONS_RADIO_RG1= OPT7 OPT8 OPTIONS can also be grouped as multiple-choice lists, where at least one option must be enabled: OPTIONS_MULTI= MG1 OPTIONS_MULTI_MG1= OPT5 OPT6 OPTIONS can also be grouped as multiple-choice lists, where none or any option can be enabled: OPTIONS_GROUP= GG1 OPTIONS_GROUP_GG1= OPT9 OPT10 OPTIONS are unset by default, unless they are listed in OPTIONS_DEFAULT: OPTIONS_DEFAULT= OPT1 OPT3 OPT6 OPTIONS definitions must appear before the inclusion of bsd.port.options.mk. The PORT_OPTIONS variable can only be tested after the inclusion of bsd.port.options.mk. Inclusion of bsd.port.pre.mk can be used instead, too, and is still widely used in ports written before the introduction of bsd.port.options.mk. But be aware that some variables will not work as expected after the inclusion of bsd.port.pre.mk, typically some USE_* flags. Simple Use of <varname>OPTIONS</varname> OPTIONS_DEFINE= FOO BAR FOO_DESC= Option foo support BAR_DESC= Feature bar support OPTIONS_DEFAULT=FOO # Will add --with-foo / --without-foo FOO_CONFIGURE_WITH= foo BAR_RUN_DEPENDS= bar:${PORTSDIR}/bar/bar .include <bsd.port.mk> Check for Unset Port <varname>OPTIONS</varname> .if ! ${PORT_OPTIONS:MEXAMPLES} CONFIGURE_ARGS+=--without-examples .endif Though, you should use the following so that the configure knob is really enabled and disabled when the option is. # Will add --with-examples / --without-examples EXAMPLES_CONFIGURE_WITH= examples Practical Use of <varname>OPTIONS</varname> OPTIONS_DEFINE= EXAMPLES OPTIONS_SINGLE= BACKEND OPTIONS_SINGLE_BACKEND= MYSQL PGSQL BDB OPTIONS_MULTI= AUTH OPTIONS_MULTI_AUTH= LDAP PAM SSL EXAMPLES_DESC= Install extra examples MYSQL_DESC= Use MySQL as backend PGSQL_DESC= Use PostgreSQL as backend BDB_DESC= Use Berkeley DB as backend LDAP_DESC= Build with LDAP authentication support PAM_DESC= Build with PAM support SSL_DESC= Build with OpenSSL support OPTIONS_DEFAULT= PGSQL LDAP SSL PGSQL_USE= pgsql=yes # Will add --enable-postgres / --disable-postgres PGSQL_CONFIGURE_ENABLE= postgres ICU_LIB_DEPENDS= libicuuc.so:${PORTSDIR}/devel/icu # Will add --with-examples / --without-examples EXAMPLES_CONFIGURE_WITH= examples # Check other OPTIONS .include <bsd.port.mk> Default Options The following options are always on by default. DOCS — build and install documentation. NLS — Native Language Support. EXAMPLES — build and install examples. IPV6 — IPv6 protocol support. There is no need to add these to OPTIONS_DEFAULT. To have them active, and show up in the options selection dialog, however, they must be added to OPTIONS_DEFINE. Feature Auto-Activation When using a GNU configure script, keep an eye on which optional features are activated by auto-detection. Explicitly disable optional features you do not wish to be used by passing respective --without-xxx or --disable-xxx in CONFIGURE_ARGS. Wrong Handling of an Option .if ${PORT_OPTIONS:MFOO} LIB_DEPENDS+= libfoo.so:${PORTSDIR}/devel/foo CONFIGURE_ARGS+= --enable-foo .endif In the example above, imagine a library libfoo is installed on the system. The user does not want this application to use libfoo, so he toggled the option off in the make config dialog. But the application's configure script detects the library present in the system and includes its support in the resulting executable. Now when the user decides to remove libfoo from the system, the ports system does not protest (no dependency on libfoo was recorded) but the application breaks. Correct Handling of an Option FOO_LIB_DEPENDS= libfoo.so:${PORTSDIR}/devel/foo # Will add --enable-foo / --disable-foo FOO_CONFIGURE_ENABLE= foo Under some circumstances, the shorthand conditional syntax can cause problems with complex constructs. If you receive errors such as Malformed conditional, an alternative syntax can be used. .if !empty(VARIABLE:MVALUE) # as an alternative to .if ${VARIABLE:MVALUE} Options Helpers There are some macros to help simplify conditional values which differ based on the options set. <varname>OPTIONS_SUB</varname> If OPTIONS_SUB is set to yes then each of the options added to OPTIONS_DEFINE will be added to PLIST_SUB and SUB_LIST, for example: OPTIONS_DEFINE= OPT1 OPTIONS_SUB= yes is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} PLIST_SUB+= OPT1="" NO_OPT1="@comment " SUB_LIST+= OPT1="" NO_OPT1="@comment " .else PLIST_SUB+= OPT1="@comment " NO_OPT1="" SUB_LIST+= OPT1="@comment " NO_OPT1="" .endif The value of OPTIONS_SUB is ignored. Setting it to any value will add PLIST_SUB and SUB_LIST entries for all options. <varname><replaceable>OPT</replaceable>_USE</varname> For each key=value pair in OPT_USE the corresponding USE_KEY variable will be set to value. If value has spaces in it, replace them with commas, they will be changed back to spaces during processing. For example: OPTIONS_DEFINE= OPT1 OPT1_USE= mysql=yes xorg=x11,xextproto,xext,xrandr is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} USE_MYSQL= yes USE_XORG= x11 xextproto xext xrandr .endif <varname><replaceable>OPT</replaceable>_CONFIGURE_ENABLE</varname> If OPT_CONFIGURE_ENABLE is set then --enable-${OPT_CONFIGURE_ENABLE} or --disable-${OPT_CONFIGURE_ENABLE} will be added to CONFIGURE_ARGS depending on the value of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_CONFIGURE_ENABLE= test is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} CONFIGURE_ARGS+= --enable-test .else CONFIGURE_ARGS+= --disable-test .endif <varname><replaceable>OPT</replaceable>_CONFIGURE_WITH</varname> If OPT_CONFIGURE_WITH is set then --with-${OPT_CONFIGURE_WITH} or --without-${OPT_CONFIGURE_WITH} will be added to CONFIGURE_ARGS depending on the status of the option OPT. An optional argument can be specified with an = symbol. This argument is only appended to the --with-opt configure option. For example: OPTIONS_DEFINE= OPT1 OPT2 OPT1_CONFIGURE_WITH= test1 OPT1_CONFIGURE_WITH= test2=exhaustive is equivalent to: OPTIONS_DEFINE= OPT1 OPT2 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} CONFIGURE_ARGS+= --with-test1 .else CONFIGURE_ARGS+= --without-test1 .endif .if ${PORT_OPTIONS:MOPT2} CONFIGURE_ARGS+= --with-test2=exhaustive .else CONFIGURE_ARGS+= --without-test2 .endif <varname><replaceable>OPT</replaceable>_CONFIGURE_ON</varname> If OPT_CONFIGURE_ON is set then its value will be appended to CONFIGURE_ARGS depending on the status of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_CONFIGURE_ON= --add-test is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} CONFIGURE_ARGS+= --add-test .endif <varname><replaceable>OPT</replaceable>_CONFIGURE_OFF</varname> If OPT_CONFIGURE_OFF is set then its value will be appended to CONFIGURE_ARGS depending on the status of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_CONFIGURE_OFF= --no-test is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ! ${PORT_OPTIONS:MOPT1} CONFIGURE_ARGS+= --no-test .endif <varname><replaceable>OPT</replaceable>_CMAKE_ON</varname> If OPT_CMAKE_ON is set then its value will be appended to CMAKE_ARGS depending on the status of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_CMAKE_ON= -DTEST:BOOL=true is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} CMAKE_ARGS+= -DTEST:BOOL=true .endif <varname><replaceable>OPT</replaceable>_CMAKE_OFF</varname> If OPT_CMAKE_OFF is set then its value will be appended to CMAKE_ARGS depending on the status of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_CMAKE_OFF= -DTEST:BOOL=false is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ! ${PORT_OPTIONS:MOPT1} CMAKE_ARGS+= -DTEST:BOOL=false .endif Dependencies For any of the following dependency type: PKG_DEPENDS EXTRACT_DEPENDS PATCH_DEPENDS FETCH_DEPENDS BUILD_DEPENDS LIB_DEPENDS RUN_DEPENDS <varname><replaceable>OPT</replaceable>_<replaceable>ABOVEVARIABLE</replaceable></varname> If OPT_ABOVEVARIABLE is defined then its value will be appended to ABOVEVARIABLE depending on the status of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_LIB_DEPENDS= liba.so:${PORTSDIR}/devel/a is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} LIB_DEPENDS+= liba.so:${PORTSDIR}/devel/a .endif <varname><replaceable>OPT</replaceable>_<replaceable>ABOVEVARIABLE</replaceable>_OFF</varname> If OPT_ABOVEVARIABLE_OFF is set then a dependency of type ABOVEVARIABLE will be added when option OPT is not selected. For example: OPTIONS_DEFINE= OPT1 OPT1_LIB_DEPENDS_OFF= liba.so:${PORTSDIR}/devel/a is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> . if ! ${PORT_OPTIONS:MOPT1} LIB_DEPENDS+= liba.so:${PORTSDIR}/devel/a .endif Generic Variables Replacement For any of the following variables: ALL_TARGET CATEGORIES CFLAGS CPPFLAGS CXXFLAGS CONFIGURE_ENV CONFLICTS CONFLICTS_BUILD CONFLICTS_INSTALL DISTFILES EXTRA_PATCHES INFO INSTALL_TARGET LDFLAGS MAKE_ARGS MAKE_ENV PATCH_SITES PATCHFILES PLIST_FILES PLIST_DIRS PLIST_DIRSTRY + + PLIST_SUB + + USES Some of these variables, at least ALL_TARGET and INSTALL_TARGET, have their default values set after the options are processed. With the following lines in the Makefile: ALL_TARGET= all DOCS_ALL_TARGET= doc If the DOCS option is enabled, ALL_TARGET will have a final value of all doc; if the option is disabled, it would have a value of all. With only the options helper line in the Makefile: DOCS_ALL_TARGET= doc If the DOCS option is enabled, ALL_TARGET will have a final value of doc; if the option is disabled, it would have a value of all. <varname><replaceable>OPT</replaceable>_<replaceable>ABOVEVARIABLE</replaceable></varname> If OPT_ABOVEVARIABLE is defined then its value will be appended to ABOVEVARIABLE depending on the status of the option OPT, for example: OPTIONS_DEFINE= OPT1 OPT1_USES= gmake OPT1_CFLAGS= -DTEST is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ${PORT_OPTIONS:MOPT1} USES+= gmake CFLAGS+= -DTEST .endif <varname><replaceable>OPT</replaceable>_<replaceable>ABOVEVARIABLE</replaceable>_OFF</varname> If OPT_ABOVEVARIABLE_OFF is set then a flag ABOVEVARIABLE will be automatically set when option OPT is not selected. For example: OPTIONS_DEFINE= OPT1 OPT1_USES_OFF=gmake is equivalent to: OPTIONS_DEFINE= OPT1 .include <bsd.port.options.mk> .if ! ${PORT_OPTIONS:MOPT1} USES+= gmake .endif Specifying the Working Directory Each port is extracted in to a working directory, which must be writable. The ports system defaults to having the DISTFILES unpack in to a directory called ${DISTNAME}. In other words, if you have set: PORTNAME= foo PORTVERSION= 1.0 then the port's distribution files contain a top-level directory, foo-1.0, and the rest of the files are located under that directory. There are a number of variables you can override if that is not the case. <varname>WRKSRC</varname> The variable lists the name of the directory that is created when the application's distfiles are extracted. If our previous example extracted into a directory called foo (and not foo-1.0) you would write: WRKSRC= ${WRKDIR}/foo or possibly WRKSRC= ${WRKDIR}/${PORTNAME} <varname>NO_WRKSUBDIR</varname> If the port does not extract in to a subdirectory at all then you should set NO_WRKSUBDIR to indicate that. NO_WRKSUBDIR= yes Conflict Handling There are three different variables to register a conflict between packages and ports: CONFLICTS, CONFLICTS_INSTALL and CONFLICTS_BUILD. The conflict variables automatically set the variable IGNORE, which is more fully documented in . When removing one of several conflicting ports, it is advisable to retain the CONFLICTS entries in those other ports for a few months to cater for users who only update once in a while. <varname>CONFLICTS_INSTALL</varname> If your package cannot coexist with other packages (because of file conflicts, runtime incompatibilities, etc.), list the other package names in the CONFLICTS_INSTALL variable. You can use shell globs like * and ? here. Package names should be enumerated the same way they appear in /var/db/pkg. Please make sure that CONFLICTS_INSTALL does not match this port's package itself. Otherwise enforcing its installation with FORCE_PKG_REGISTER will no longer work. The CONFLICTS_INSTALL check is done after the build stage and prior to the install stage. <varname>CONFLICTS_BUILD</varname> If your port cannot be built if a certain port is already installed, list the other port names in the CONFLICTS_BUILD variable. You can use shell globs like * and ? here. Package names should be enumerated the same way they appear in /var/db/pkg. The CONFLICTS_BUILD check is done prior to the build stage. Build conflicts are not recorded in the resulting package. <varname>CONFLICTS</varname> If your port cannot be built if a certain port is already installed and the resulting package cannot coexist with the other package, list the other package name in the CONFLICTS variable. You can use shell globs like * and ? here. Packages names should be enumerated the same way they appear in /var/db/pkg. Please make sure that CONFLICTS_INSTALL does not match this port's package itself. Otherwise enforcing its installation with FORCE_PKG_REGISTER will no longer work. The CONFLICTS check is done prior to the build stage and prior to the install stage. Installing Files <varname>INSTALL_*</varname> Macros Use the macros provided in bsd.port.mk to ensure correct modes of files in the port's *-install targets. Set ownership directly in pkg-plist with the corresponding entries, such as @owner owner and @group group. These operators work until being overridden, or until the end of pkg-plist, so do not forget to reset them after they are no longer needed. The default ownership is root:wheel. INSTALL_PROGRAM is a command to install binary executables. INSTALL_SCRIPT is a command to install executable scripts. INSTALL_LIB is a command to install shared libraries (but not static libraries). INSTALL_KLD is a command to install kernel loadable modules. Some architectures do not like having the modules stripped, so use this command instead of INSTALL_PROGRAM. INSTALL_DATA is a command to install sharable data, including static libraries. INSTALL_MAN is a command to install manpages and other documentation (it does not compress anything). These are basically the install command with all the appropriate flags. Do not use INSTALL_LIB to install static libraries, because stripping them render them useless. Use INSTALL_DATA instead. Stripping Binaries and Shared Libraries Do not strip binaries manually unless you have to. All binaries should be stripped, but the INSTALL_PROGRAM macro will install and strip a binary at the same time (see the next section). The INSTALL_LIB macro does the same thing to shared libraries. If you need to strip a file, but wish to use neither INSTALL_PROGRAM nor INSTALL_LIB macros, ${STRIP_CMD} will strip your program or shared library. This is typically done within the post-install target. For example: post-install: ${STRIP_CMD} ${STAGEDIR}${PREFIX}/bin/xdl When multiple files need to be stripped: post-install: .for l in geometry media body track world ${STRIP_CMD} ${STAGEDIR}${PREFIX}/lib/lib${PORTNAME}-${l}.so.0 .endfor Use &man.file.1; on a file to determine if it has been stripped. Binaries are reported by &man.file.1; as stripped, or not stripped. Additionally, &man.strip.1; will detect programs that have already been stripped and exit cleanly. Installing a Whole Tree of Files Sometimes, a large number of files must be installed while preserving their hierarchical organization. For example, copying over a whole directory tree from WRKSRC to a target directory under PREFIX. Note that PREFIX, EXAMPLESDIR, DATADIR, and other path variables must always be prepended with STAGEDIR to respect staging (see ). Two macros exist for this situation. The advantage of using these macros instead of cp is that they guarantee proper file ownership and permissions on target files. The first macro, COPYTREE_BIN, will set all the installed files to be executable, thus being suitable for installing into PREFIX/bin. The second macro, COPYTREE_SHARE, does not set executable permissions on files, and is therefore suitable for installing files under PREFIX/share target. post-install: ${MKDIR} ${STAGEDIR}${EXAMPLESDIR} (cd ${WRKSRC}/examples && ${COPYTREE_SHARE} . ${STAGEDIR}${EXAMPLESDIR}) This example will install the contents of examples directory in the vendor distfile to the proper examples location of your port. post-install: ${MKDIR} ${STAGEDIR}${DATADIR}/summer (cd ${WRKSRC}/temperatures && ${COPYTREE_SHARE} "June July August" ${STAGEDIR}${DATADIR}/summer) And this example will install the data of summer months to the summer subdirectory of a DATADIR. Additional find arguments can be passed via the third argument to the COPYTREE_* macros. For example, to install all files from the first example except Makefiles, one can use the following command. post-install: ${MKDIR} ${STAGEDIR}${EXAMPLESDIR} (cd ${WRKSRC}/examples && \ ${COPYTREE_SHARE} . ${STAGEDIR}${EXAMPLESDIR} "! -name Makefile") These macros do not add the installed files to pkg-plist. They must be added manually. For optional documentation (PORTDOCS, see ) and examples (PORTEXAMPLES), the %%PORTDOCS%% or %%PORTEXAMPLES%% prefixes must be prepended in pkg-plist. Install Additional Documentation If your software has some documentation other than the standard man and info pages that you think is useful for the user, install it under PREFIX/share/doc. This can be done, like the previous item, in the post-install target. Create a new directory for your port. The directory name should reflect what the port is. This usually means PORTNAME. However, if you think the user might want different versions of the port to be installed at the same time, you can use the whole PKGNAME. Since only the files listed in pkg-plist are installed, it is safe to always install documentation to STAGEDIR (see ). Hence .if blocks are only needed when the installed files are large enough to cause significant I/O overhead. post-install: ${MKDIR} ${STAGEDIR}${DOCSDIR} ${INSTALL_MAN} ${WRKSRC}/docs/xvdocs.ps ${STAGEDIR}${DOCSDIR} Here are some handy variables and how they are expanded by default when used in the Makefile: DATADIR gets expanded to PREFIX/share/PORTNAME. DATADIR_REL gets expanded to share/PORTNAME. DOCSDIR gets expanded to PREFIX/share/doc/PORTNAME. DOCSDIR_REL gets expanded to share/doc/PORTNAME. EXAMPLESDIR gets expanded to PREFIX/share/examples/PORTNAME. EXAMPLESDIR_REL gets expanded to share/examples/PORTNAME. The DOCS option only controls additional documentation installed in DOCSDIR. It does not apply to standard man pages and info pages. Things installed in DATADIR and EXAMPLESDIR are controlled by DATA and EXAMPLES options, respectively. These variables are exported to PLIST_SUB. Their values will appear there as pathnames relative to PREFIX if possible. That is, share/doc/PORTNAME will be substituted for %%DOCSDIR%% in the packing list by default, and so on. (See more on pkg-plist substitution here.) All conditionally installed documentation files and directories should be included in pkg-plist with the %%PORTDOCS%% prefix, for example: %%PORTDOCS%%%%DOCSDIR%%/AUTHORS %%PORTDOCS%%%%DOCSDIR%%/CONTACT %%PORTDOCS%%@dirrm %%DOCSDIR%% As an alternative to enumerating the documentation files in pkg-plist, a port can set the variable PORTDOCS to a list of file names and shell glob patterns to add to the final packing list. The names will be relative to DOCSDIR. Therefore, a port that utilizes PORTDOCS and uses a non-default location for its documentation should set DOCSDIR accordingly. If a directory is listed in PORTDOCS or matched by a glob pattern from this variable, the entire subtree of contained files and directories will be registered in the final packing list. If the DOCS option has been unset then files and directories listed in PORTDOCS would not be installed or added to port packing list. Installing the documentation at PORTDOCS as shown above remains up to the port itself. A typical example of utilizing PORTDOCS looks as follows: PORTDOCS= README.* ChangeLog docs/* The equivalents of PORTDOCS for files installed under DATADIR and EXAMPLESDIR are PORTDATA and PORTEXAMPLES, respectively. The contents of pkg-message are displayed upon installation. See the section on using pkg-message for details. pkg-message does not need to be added to pkg-plist. Subdirectories Under <varname>PREFIX</varname> Try to let the port put things in the right subdirectories of PREFIX. Some ports lump everything and put it in the subdirectory with the port's name, which is incorrect. Also, many ports put everything except binaries, header files and manual pages in a subdirectory of lib, which does not work well with the BSD paradigm. Many of the files should be moved to one of the following: etc (setup/configuration files), libexec (executables started internally), sbin (executables for superusers/managers), info (documentation for info browser) or share (architecture independent files). See &man.hier.7; for details; the rules governing /usr pretty much apply to /usr/local too. The exception are ports dealing with USENET news. They may use PREFIX/news as a destination for their files.
