- * arch.c --
- * Functions to manipulate libraries, archives and their members.
- *
- * Once again, cacheing/hashing comes into play in the manipulation
- * of archives. The first time an archive is referenced, all of its members'
- * headers are read and hashed and the archive closed again. All hashed
- * archives are kept on a list which is searched each time an archive member
- * is referenced.
- *
- * The interface to this module is:
- * Arch_ParseArchive Given an archive specification, return a list
- * of GNode's, one for each member in the spec.
- * FALSE is returned if the specification is
- * invalid for some reason.
- *
- * Arch_Touch Alter the modification time of the archive
- * member described by the given node to be
- * the current time.
- *
- * Arch_TouchLib Update the modification time of the library
- * described by the given node. This is special
- * because it also updates the modification time
- * of the library's table of contents.
- *
- * Arch_MTime Find the modification time of a member of
- * an archive *in the archive*. The time is also
- * placed in the member's GNode. Returns the
- * modification time.
- *
- * Arch_MemTime Find the modification time of a member of
- * an archive. Called when the member doesn't
- * already exist. Looks in the archive for the
- * modification time. Returns the modification
- * time.
- *
- * Arch_FindLib Search for a library along a path. The
- * library name in the GNode should be in
- * -l<name> format.
- *
- * Arch_LibOODate Special function to decide if a library node
- * is out-of-date.
- *
- * Arch_Init Initialize this module.

-/*
- * A search path consists of a list of Dir structures. A Dir structure
- * has in it the name of the directory and a hash table of all the files
- * in the directory. This is used to cut down on the number of system
- * calls necessary to find implicit dependents and their like. Since
- * these searches are made before any actions are taken, we need not
- * worry about the directory changing due to creation commands. If this
- * hampers the style of some makefiles, they must be changed.
- *
- * A list of all previously-read directories is kept in the
- * openDirectories list. This list is checked first before a directory
- * is opened.
- *
- * The need for the caching of whole directories is brought about by
- * the multi-level transformation code in suff.c, which tends to search
- * for far more files than regular make does. In the initial
- * implementation, the amount of time spent performing "stat" calls was
- * truly astronomical. The problem with hashing at the start is,
- * of course, that pmake doesn't then detect changes to these directories
- * during the course of the make. Three possibilities suggest themselves:
- *
- * 1) just use stat to test for a file's existence. As mentioned
- * above, this is very inefficient due to the number of checks
- * engendered by the multi-level transformation code.
- * 2) use readdir() and company to search the directories, keeping
- * them open between checks. I have tried this and while it
- * didn't slow down the process too much, it could severely
- * affect the amount of parallelism available as each directory
- * open would take another file descriptor out of play for
- * handling I/O for another job. Given that it is only recently
- * that UNIX OS's have taken to allowing more than 20 or 32
- * file descriptors for a process, this doesn't seem acceptable
- * to me.
- * 3) record the mtime of the directory in the Dir structure and
- * verify the directory hasn't changed since the contents were
- * hashed. This will catch the creation or deletion of files,
- * but not the updating of files. However, since it is the
- * creation and deletion that is the problem, this could be
- * a good thing to do. Unfortunately, if the directory (say ".")
- * were fairly large and changed fairly frequently, the constant
- * rehashing could seriously degrade performance. It might be
- * good in such cases to keep track of the number of rehashes
- * and if the number goes over a (small) limit, resort to using
- * stat in its place.
- *
- * An additional thing to consider is that pmake is used primarily
- * to create C programs and until recently pcc-based compilers refused
- * to allow you to specify where the resulting object file should be
- * placed. This forced all objects to be created in the current
- * directory. This isn't meant as a full excuse, just an explanation of
- * some of the reasons for the caching used here.
- *
- * One more note: the location of a target's file is only performed
- * on the downward traversal of the graph and then only for terminal
- * nodes in the graph. This could be construed as wrong in some cases,
- * but prevents inadvertent modification of files when the "installed"
- * directory for a file is provided in the search path.
- *
- * Another data structure maintained by this module is an mtime
- * cache used when the searching of cached directories fails to find
- * a file. In the past, Path_FindFile would simply perform an access()
- * call in such a case to determine if the file could be found using
- * just the name given. When this hit, however, all that was gained
- * was the knowledge that the file existed. Given that an access() is
- * essentially a stat() without the copyout() call, and that the same
- * filesystem overhead would have to be incurred in Dir_MTime, it made
- * sense to replace the access() with a stat() and record the mtime
- * in a cache for when Dir_MTime was actually called.

-.Dt MAKE 1
-.Os
-.Sh NAME
-.Nm make
-.Nd maintain program dependencies
-.Sh SYNOPSIS
-.Nm
-.Op Fl ABPSXeiknpqrstv
-.Op Fl C Ar directory
-.Op Fl D Ar variable
-.Op Fl d Ar flags
-.Op Fl E Ar variable
-.Op Fl f Ar makefile
-.Op Fl I Ar directory
-.Bk -words
-.Op Fl j Ar max_jobs
-.Op Fl m Ar directory
-.Ek
-.Op Fl V Ar variable
-.Op Fl x Ar warning_options
-.Op Ar variable Ns No = Ns Ar value
-.Op Ar target ...
-.Sh DESCRIPTION
-The
-.Nm
-utility is a program designed to simplify the maintenance of other programs.
-Its input is a list of specifications
-describing dependency relationships between the generation of
-files and programs.
-.Pp
-First of all, the initial list of specifications will be read
-from the system makefile,
-.Pa sys.mk ,
-unless inhibited with the
-.Fl r
-option.
-The standard
-.Pa sys.mk
-as shipped with
-.Fx
-also handles
-.Xr make.conf 5 ,
-the default path to which
-can be altered via the
-.Nm
-variable
-.Va __MAKE_CONF .
-.Pp
-Then the first of
-.Pa BSDmakefile ,
-.Pa makefile ,
-and
-.Pa Makefile
-that can be found in the current directory, object directory (see
-.Va .OBJDIR ) ,
-or search path (see the
-.Fl I
-option)
-will be read for the main list of dependency specifications.
-A different makefile or list of them can be supplied via the
-.Fl f
-option(s).
-Finally, if the file
-.Pa .depend
-can be found in any of the aforesaid locations, it will also be read (see
-.Xr mkdep 1 ) .
-.Pp
-When
-.Nm
-searches for a makefile, its name takes precedence over its location.
-For instance,
-.Pa BSDmakefile
-in the object directory will be favored over
-.Pa Makefile
-in the current directory.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl A
-Make archive errors non-fatal, causing
-.Nm
-to just skip the remainder
-or all of the archive and continue after printing a message.
-.It Fl B
-Try to be backwards compatible by executing a single shell per command and
-by executing the commands to make the sources of a dependency line in sequence.
-This is turned on by default unless
-.Fl j
-is used.
-.It Fl C Ar directory
-Change to
-.Ar directory
-before reading the makefiles or doing anything else.
-If multiple
-.Fl C
-options are specified, each is interpreted relative to the previous one:
-.Fl C Pa / Fl C Pa etc
-is equivalent to
-.Fl C Pa /etc .
-.It Fl D Ar variable
-Define
-.Ar variable
-to be 1, in the global context.
-.It Fl d Ar flags
-Turn on debugging, and specify which portions of
-.Nm
-are to print debugging information.
-Argument
-.Ar flags
-is one or more of the following:
-.Bl -tag -width Ds
-.It Ar A
-Print all possible debugging information;
-equivalent to specifying all of the debugging flags.
-.It Ar a
-Print debugging information about archive searching and caching.
-.It Ar c
-Print debugging information about conditional evaluation.
-.It Ar d
-Print debugging information about directory searching and caching.
-.It Ar f
-Print debugging information about the execution of for loops.
-.It Ar "g1"
-Print the input graph before making anything.
-.It Ar "g2"
-Print the input graph after making everything, or before exiting
-on error.
-.It Ar j
-Print debugging information about running multiple shells.
-.It Ar l
-Print commands in Makefiles regardless of whether or not they are prefixed
-by @ or other "quiet" flags.
-Also known as "loud" behavior.
-.It Ar m
-Print debugging information about making targets, including modification
-dates.
-.It Ar s
-Print debugging information about suffix-transformation rules.
-.It Ar t
-Print debugging information about target list maintenance.
-.It Ar v
-Print debugging information about variable assignment.
-.El
-.It Fl E Ar variable
-Specify a variable whose environment value (if any) will override
-macro assignments within makefiles.
-.It Fl e
-Specify that environment values override macro assignments within
-makefiles for all variables.
-.It Fl f Ar makefile
-Specify a makefile to read instead of the default one.
-If
-.Ar makefile
-is not an absolute pathname,
-.Nm
-will search for it as described above.
-In case
-.Ar makefile
-is
-.Sq Fl ,
-standard input is read.
-Multiple
-.Fl f
-options can be supplied,
-and the makefiles will be read in that order.
-Unlike the other command-line options,
-.Fl f
-is neither stored in
-.Va .MAKEFLAGS
-nor pushed down to sub-makes via
-.Ev MAKEFLAGS .
-See below for more details on these variables.
-.It Fl I Ar directory
-Specify a directory in which to search for makefiles and included makefiles.
-Multiple
-.Fl I
-options can be specified to form a search path.
-The system makefile directory (or directories, see the
-.Fl m
-option) is automatically appended at the tail of this path.
-.It Fl i
-Ignore non-zero exit of shell commands in the makefile.
-Equivalent to specifying
-.Sq Ic \-
-before each command line in the makefile.
-.It Fl j Ar max_jobs
-Specify the maximum number of jobs that
-.Nm
-may have running at any one time.
-Turns compatibility mode off, unless the
-.Fl B
-flag is also specified.
-.It Fl k
-Continue processing after errors are encountered, but only on those targets
-that do not depend on the target whose creation caused the error.
-.It Fl m Ar directory
-Specify a directory in which to search for
-the system makefile and makefiles included via the <...> style.
-Multiple
-.Fl m
-options can be specified to form a search path.
-This path will override the default system include path,
-.Pa /usr/share/mk .
-The system include path will always be appended to the search path used
-for "..."-style inclusions and makefile searches (see the
-.Fl I
-option).
-.Pp
-If a file or directory name in the
-.Fl m
-argument (or the
-.Ev MAKESYSPATH
-environment variable) starts with the string
-.Qq \&.../
-then
-.Nm
-will search for the specified file or directory named in the remaining part
-of the argument string.
-The search starts with the current directory of the Makefile and then works
-upward towards the root of the filesystem.
-If the search is successful,
-then the resulting directory replaces the
-.Qq \&.../
-specification in the
-.Fl m
-argument.
-If used, this feature allows
-.Nm
-to easily search in the current source tree for customized sys.mk files
-(e.g. by using
-.Qq \&.../mk/sys.mk
-as an argument).
-Note that a
-.Fl C
-that are earlier on the command line affect where
-.Fl m Qq \&.../
-searches.
-.It Fl n
-Display the commands that would have been executed, but do not actually
-execute them.
-.It Fl P
-Collate the output of a given job and display it only when the job finishes,
-instead of mixing the output of parallel jobs together.
-This option has no effect unless
-.Fl j
-is used too.
-.It Fl p
-Only print the input graph, not executing any commands.
-The output is the same as
-.Fl d Ar g1 .
-When combined with
-.Fl f Pa /dev/null ,
-only the builtin rules of
-.Nm
-are displayed.
-.It Fl Q
-Be extra quiet.
-For multi-job makes, this will cause file banners not to be generated.
-.It Fl q
-Do not execute any commands, but exit 0 if the specified targets are
-up-to-date and 1, otherwise.
-.It Fl r
-Do not process the system makefile.
-.It Fl S
-Stop processing when an error is encountered.
-Default behaviour.
-This is needed to negate the
-.Fl k
-option during recursive builds.
-.It Fl s
-Do not echo any commands as they are executed.
-Equivalent to specifying
-.Sq Ic @
-before each command line in the makefile.
-.It Fl t
-Rather than re-building a target as specified in the makefile, create it
-or update its modification time to make it appear up-to-date.
-.It Fl V Ar variable
-Print
-.Nm Ns 's
-idea of the value of
-.Ar variable ,
-in the global context.
-Do not build any targets.
-Multiple instances of this option may be specified;
-the variables will be printed one per line,
-with a blank line for each null or undefined variable.
-If
-.Ar variable
-contains a
-.Sq Ic $
-then the value will be expanded before printing.
-.It Fl v
-Be extra verbose.
-Print any extra information.
-.It Fl X
-When using the
-.Fl V
-option to print the values of variables,
-do not recursively expand the values.
-.It Ar variable Ns No = Ns Ar value
-Set the value of the variable
-.Ar variable
-to
-.Ar value .
-.It Fl x Ar warning_options
-Specify extended warning options.
-This option may be specified several times.
-A
-.Ar warning_option
-can be prefixed with
-.Dq Li no
-in which case the warning is switched off.
-The currently available options are:
-.Bl -tag -width indent
-.It Li dirsyntax
-Warn if anything except blanks and comments follows an
-.Ic .endif
-or
-.Ic .else
-directive.
-.El
-.Pp
-See also the
-.Ic .WARN
-special target.
-.El
-.Pp
-There are seven different types of lines in a makefile: file dependency
-specifications, shell commands, variable assignments, include statements,
-conditional directives, for loops, and comments.
-.Pp
-In general, lines may be continued from one line to the next by ending
-them with a backslash
-.Pq Ql \e .
-The trailing newline character and initial whitespace on the following
-line are compressed into a single space.
-.Sh FILE DEPENDENCY SPECIFICATIONS
-Dependency lines consist of one or more targets, an operator, and zero
-or more sources.
-This creates a relationship where the targets
-.Dq depend
-on the sources
-and are usually created from them.
-The exact relationship between the target and the source is determined
-by the operator that separates them.
-The three operators are as follows:
-.Bl -tag -width flag
-.It Ic \&:
-A target is considered out-of-date if its modification time is less than
-those of any of its sources.
-Sources for a target accumulate over dependency lines when this operator
-is used.
-The target is removed if
-.Nm
-is interrupted.
-.It Ic \&!
-Targets are always re-created, but not until all sources have been
-examined and re-created as necessary.
-Sources for a target accumulate over dependency lines when this operator
-is used.
-The target is removed if
-.Nm
-is interrupted.
-.It Ic ::
-If no sources are specified, the target is always re-created.
-Otherwise, a target is considered out-of-date if any of its sources has
-been modified more recently than the target.
-Sources for a target do not accumulate over dependency lines when this
-operator is used.
-The target will not be removed if
-.Nm
-is interrupted.
-.El
-.Pp
-Targets and sources may contain the shell wildcard expressions
-.Ql \&? ,
-.Ql * ,
-.Ql []
-and
-.Ql {} .
-The expressions
-.Ql \&? ,
-.Ql *
-and
-.Ql []
-may only be used as part of the final
-component of the target or source, and must be used to describe existing
-files.
-The expression
-.Ql {}
-need not necessarily be used to describe existing files.
-Expansion is in directory order, not alphabetically as done in the shell.
-.Sh SHELL COMMANDS
-Each target may have associated with it a series of shell commands, normally
-used to create the target.
-Each of the commands in this script
-.Em must
-be preceded by a tab.
-While any target may appear on a dependency line, only one of these
-dependencies may be followed by a creation script, unless the
-.Sq Ic ::
-operator is used.
-.Pp
-If the first characters of the command line are
-.Sq Ic @ ,
-.Sq Ic \- ,
-and/or
-.Sq Ic + ,
-the command is treated specially.
-A
-.Sq Ic @
-causes the command not to be echoed before it is executed.
-A
-.Sq Ic \-
-causes any non-zero exit status of the command line to be ignored.
-A
-.Sq Ic +
-causes the command to be executed even if
-.Fl n
-is specified on the command line.
-.Sh VARIABLE ASSIGNMENTS
-Variables in
-.Nm
-are much like variables in the shell, and, by tradition,
-consist of all upper-case letters.
-The five operators that can be used to assign values to variables are as
-follows:
-.Bl -tag -width Ds
-.It Ic =
-Assign the value to the variable.
-Any previous value is overridden.
-.It Ic +=
-Append the value to the current value of the variable.
-.It Ic ?=
-Assign the value to the variable if it is not already defined.
-.It Ic :=
-Assign with expansion, i.e., expand the value before assigning it
-to the variable.
-Normally, expansion is not done until the variable is referenced.
-.It Ic !=
-Expand the value and pass it to the shell for execution and assign
-the result to the variable.
-Any newlines in the result are replaced with spaces.
-.El
-.Pp
-Any whitespace before the assigned
-.Ar value
-is removed; if the value is being appended, a single space is inserted
-between the previous contents of the variable and the appended value.
-.Pp
-Variables are expanded by surrounding the variable name with either
-curly braces
-.Pq Ql {}
-or parentheses
-.Pq Ql ()
-and preceding it with
-a dollar sign
-.Pq Ql $ .
-If the variable name contains only a single letter, the surrounding
-braces or parentheses are not required.
-This shorter form is not recommended.
-.Pp
-Variable substitution occurs at two distinct times, depending on where
-the variable is being used.
-Variables in dependency lines are expanded as the line is read.
-Variables in shell commands are expanded when the shell command is
-executed.
-.Pp
-The four different classes of variables (in order of increasing precedence)
-are:
-.Bl -tag -width Ds
-.It Environment variables
-Variables defined as part of
-.Nm Ns 's
-environment.
-.It Global variables
-Variables defined in the makefile or in included makefiles.
-.It Command line variables
-Variables defined as part of the command line and variables
-obtained from the
-.Ev MAKEFLAGS
-environment variable or the
-.Ic .MAKEFLAGS
-target.
-.It Local variables
-Variables that are defined specific to a certain target.
-.El
-.Pp
-If the name of an environment variable appears in a makefile
-on the left-hand side of an assignment,
-a global variable with the same name is created, and the latter
-shadows the former as per their relative precedences.
-The environment is not changed in this case, and the change
-is not exported to programs executed by
-.Nm .
-However, a command-line variable actually replaces
-the environment variable of the same name if the latter exists,
-which is visible to child programs.
-.Pp
-There are seven local variables in
-.Nm :
-.Bl -tag -width ".ARCHIVE"
-.It Va .ALLSRC
-The list of all sources for this target; also known as
-.Sq Va > .
-.It Va .ARCHIVE
-The name of the archive file; also known as
-.Sq Va \&! .
-.It Va .IMPSRC
-The name/path of the source from which the target is to be transformed
-(the
-.Dq implied
-source); also known as
-.Sq Va < .
-.It Va .MEMBER
-The name of the archive member; also known as
-.Sq Va % .
-.It Va .OODATE
-The list of sources for this target that were deemed out-of-date; also
-known as
-.Sq Va \&? .
-.It Va .PREFIX
-The file prefix of the file, containing only the file portion, no suffix
-or preceding directory components; also known as
-.Sq Va * .
-.It Va .TARGET
-The name of the target; also known as
-.Sq Va @ .
-.El
-.Pp
-The shorter forms
-.Sq Va @ ,
-.Sq Va \&! ,
-.Sq Va < ,
-.Sq Va % ,
-.Sq Va \&? ,
-.Sq Va > ,
-and
-.Sq Va *
-are permitted for backward
-compatibility and are not recommended.
-The six variables
-.Sq Va @F ,
-.Sq Va @D ,
-.Sq Va <F ,
-.Sq Va <D ,
-.Sq Va *F ,
-and
-.Sq Va *D
-are
-permitted for compatibility with
-.At V
-makefiles and are not recommended.
-.Pp
-Four of the local variables may be used in sources on dependency lines
-because they expand to the proper value for each target on the line.
-These variables are
-.Va .TARGET ,
-.Va .PREFIX ,
-.Va .ARCHIVE ,
-and
-.Va .MEMBER .
-.Pp
-In addition,
-.Nm
-sets or knows about the following internal variables or environment
-variables:
-.Bl -tag -width ".Va .MAKEFILE_LIST"
-.It Va $
-A single dollar sign
-.Ql $ ,
-i.e.\&
-.Ql $$
-expands to a single dollar
-sign.
-.It Va MAKE
-The name that
-.Nm
-was executed with
-.Pq Va argv Ns Op 0 .
-.It Va .CURDIR
-A path to the directory where
-.Nm
-was executed.
-The
-.Nm
-utility sets
-.Va .CURDIR
-to the canonical path given by
-.Xr getcwd 3 .
-.It Va .OBJDIR
-A path to the directory where the targets are built.
-At startup,
-.Nm
-searches for an alternate directory to place target files.
-It will attempt to change into this special directory
-and will search this directory for makefiles
-not found in the current directory.
-The following directories are tried in order:
-.Pp
-.Bl -enum -compact
-.It
-${MAKEOBJDIRPREFIX}/`pwd -P`
-.It
-${MAKEOBJDIR}
-.It
-obj.${MACHINE}
-.It
-obj
-.It
-/usr/obj/`pwd -P`
-.El
-.Pp
-The first directory that
-.Nm
-successfully changes into is used.
-If either
-.Ev MAKEOBJDIRPREFIX
-or
-.Ev MAKEOBJDIR
-is set in the environment but
-.Nm
-is unable to change into the corresponding directory,
-then the current directory is used
-without checking the remainder of the list.
-If they are undefined and
-.Nm
-is unable to change into any of the remaining three directories,
-then the current directory is used.
-Note, that
-.Ev MAKEOBJDIRPREFIX
-and
-.Ev MAKEOBJDIR
-must be environment variables and should not be set on
-.Nm Ns 's
-command line.
-.Pp
-The
-.Nm
-utility sets
-.Va .OBJDIR
-to the canonical path given by
-.Xr getcwd 3 .
-.It Va .MAKEFILE_LIST
-As
-.Nm
-reads various makefiles, including the default files and any
-obtained from the command line and
-.Ic .include
-and
-.Ic .sinclude
-directives, their names will be automatically appended to the
-.Va .MAKEFILE_LIST
-variable.
-They are added right before
-.Nm
-begins to parse them, so that the name of the current makefile is the
-last word in this variable.
-.It Ev MAKEFLAGS
-The environment variable
-.Ev MAKEFLAGS
-may initially contain anything that
-may be specified on
-.Nm Ns 's
-command line,
-including
-.Fl f
-option(s).
-After processing, its contents are stored in the
-.Va .MAKEFLAGS
-global variable, although any
-.Fl f
-options are omitted.
-Then all options and variable assignments specified on
-.Nm Ns 's
-command line, except for
-.Fl f ,
-are appended to the
-.Va .MAKEFLAGS
-variable.
-.Pp
-Whenever
-.Nm
-executes a program, it sets
-.Ev MAKEFLAGS
-in the program's environment to the current value of the
-.Va .MAKEFLAGS
-global variable.
-Thus, if
-.Ev MAKEFLAGS
-in
-.Nm Ns 's
-environment contains any
-.Fl f
-options, they will not be pushed down to child programs automatically.
-The
-.Nm
-utility effectively filters out
-.Fl f
-options from the environment and command line although it
-passes the rest of its options down to sub-makes via
-.Ev MAKEFLAGS
-by default.
-.Pp
-When passing macro definitions and flag arguments in the
-.Ev MAKEFLAGS
-environment variable,
-space and tab characters are quoted by preceding them with a backslash.
-When reading the
-.Ev MAKEFLAGS
-variable from the environment,
-all sequences of a backslash and one of space or tab
-are replaced just with their second character
-without causing a word break.
-Any other occurrences of a backslash are retained.
-Groups of unquoted space, tab and newline characters cause word
-breaking.
-.It Va .MAKEFLAGS
-Initially, this global variable contains
-.Nm Ns 's
-current run-time options from the environment
-and command line as described above, under
-.Ev MAKEFLAGS .
-By modifying the contents of the
-.Va .MAKEFLAGS
-global variable, the makefile can alter the contents of the
-.Ev MAKEFLAGS
-environment variable made available for all programs which
-.Nm
-executes.
-This includes adding
-.Fl f
-option(s).
-The current value of
-.Va .MAKEFLAGS
-is just copied verbatim to
-.Ev MAKEFLAGS
-in the environment of child programs.
-.Pp
-Note that any options entered to
-.Va .MAKEFLAGS
-neither affect the current instance of
-.Nm
-nor show up in its own copy of
-.Ev MAKEFLAGS
-instantly.
-However, they do show up in the
-.Ev MAKEFLAGS
-environment variable of programs executed by
-.Nm .
-On the other hand, a direct assignment to
-.Ev MAKEFLAGS
-neither affects the current instance of
-.Nm
-nor is passed down to
-.Nm Ns 's
-children.
-Compare with the
-.Ic .MAKEFLAGS
-special target below.
-.It Va MFLAGS
-This variable is provided for backward compatibility and
-contains all the options from the
-.Ev MAKEFLAGS
-environment variable plus any options specified on
-.Nm Ns 's
-command line.
-.It Va .MAKE.PID
-The process-id of
-.Nm .
-.It Va .MAKE.PPID
-The parent process-id of
-.Nm .
-.It Va .MAKE.JOB.PREFIX
-If
-.Nm
-is run with
-.Fl j Fl v
-then output for each target is prefixed with a token
-.Ql --- target ---
-the first part of which can be controlled via
-.Va .MAKE.JOB.PREFIX .
-.br
-For example:
-.Li .MAKE.JOB.PREFIX=${.newline}---${MAKE:T}[${.MAKE.PID}]
-would produce tokens like
-.Ql ---make[1234] target ---
-or
-.Li .MAKE.JOB.PREFIX=---pid[${.MAKE.PID}],ppid[${.MAKE.PPID}]
-would produce tokens like
-.Ql ---pid[56789],ppid[1234] target ---
-making it easier to track the degree of parallelism being achieved.
-.It Va .TARGETS
-List of targets
-.Nm
-is currently building.
-.It Va .INCLUDES
-See
-.Ic .INCLUDES
-special target.
-.It Va .LIBS
-See
-.Ic .LIBS
-special target.
-.It Va MACHINE
-Name of the machine architecture
-.Nm
-is running on, obtained from the
-.Ev MACHINE
-environment variable, or through
-.Xr uname 3
-if not defined.
-.It Va MACHINE_ARCH
-Name of the machine architecture
-.Nm
-was compiled for, defined at compilation time.
-.It Va VPATH
-Makefiles may assign a colon-delimited list of directories to
-.Va VPATH .
-These directories will be searched for source files by
-.Nm
-after it has finished parsing all input makefiles.
-.El
-.Ss Variable Modifiers
-Variable expansion may be modified to select or modify each word of the
-variable (where a
-.Dq word
-is whitespace-delimited sequence of characters).
-The general format of a variable expansion is as follows:
-.Pp
-.Dl {variable[:modifier[:...]]}
-.Pp
-Each modifier begins with a colon and one of the following
-special characters.
-The colon may be escaped with a backslash
-.Pq Ql \e .
-.Bl -tag -width Cm
-.Sm off
-.It Cm :C No / Ar pattern Xo
-.No / Ar replacement
-.No / Op Cm 1g
-.Xc
-.Sm on
-Modify each word of the value,
-substituting every match of the extended regular expression
-.Ar pattern
-(see
-.Xr re_format 7 )
-with the
-.Xr ed 1 Ns \-style
-.Ar replacement
-string.
-Normally, the first occurrence of the pattern in
-each word of the value is changed.
-The
-.Ql 1
-modifier causes the substitution to apply to at most one word; the
-.Ql g
-modifier causes the substitution to apply to as many instances of the
-search pattern as occur in the word or words it is found in.
-Note that
-.Ql 1
-and
-.Ql g
-are orthogonal; the former specifies whether multiple words are
-potentially affected, the latter whether multiple substitutions can
-potentially occur within each affected word.
-.It Cm :E
-Replaces each word in the variable with its suffix.
-.It Cm :H
-Replaces each word in the variable with everything but the last component.
-.It Cm :L
-Converts variable to lower-case letters.
-(deprecated)
-.It Cm :M Ns Ar pattern
-Select only those words that match the rest of the modifier.
-The standard shell wildcard characters
-.Pf ( Ql * ,
-.Ql \&? ,
-and
-.Ql [] )
-may
-be used.
-The wildcard characters may be escaped with a backslash
-.Pq Ql \e .
-.It Cm :N Ns Ar pattern
-This is identical to
-.Cm :M ,
-but selects all words which do not match
-the rest of the modifier.
-.It Cm :O
-Order every word in the variable alphabetically.
-.It Cm :Q
-Quotes every shell meta-character in the variable, so that it can be passed
-safely through recursive invocations of
-.Nm .
-.It Cm :R
-Replaces each word in the variable with everything but its suffix.
-.Sm off
-.It Cm :S No / Ar old_string Xo
-.No / Ar new_string
-.No / Op Cm g
-.Xc
-.Sm on
-Modify the first occurrence of
-.Ar old_string
-in each word of the variable's value, replacing it with
-.Ar new_string .
-If a
-.Ql g
-is appended to the last slash of the pattern, all occurrences
-in each word are replaced.
-If
-.Ar old_string
-begins with a caret
-.Pq Ql ^ ,
-.Ar old_string
-is anchored at the beginning of each word.
-If
-.Ar old_string
-ends with a dollar sign
-.Pq Ql $ ,
-it is anchored at the end of each word.
-Inside
-.Ar new_string ,
-an ampersand
-.Pq Ql &
-is replaced by
-.Ar old_string .
-Any character may be used as a delimiter for the parts of the modifier
-string.
-The anchoring, ampersand, and delimiter characters may be escaped with a
-backslash
-.Pq Ql \e .
-.Pp
-Variable expansion occurs in the normal fashion inside both
-.Ar old_string
-and
-.Ar new_string
-with the single exception that a backslash is used to prevent the expansion
-of a dollar sign
-.Pq Ql $ ,
-not a preceding dollar sign as is usual.
-.It Ar :old_string=new_string
-This is the
-.At V
-style variable substitution.
-It must be the last modifier specified.
-If
-.Ar old_string
-or
-.Ar new_string
-do not contain the pattern matching character
-.Ar %
-then it is assumed that they are
-anchored at the end of each word, so only suffixes or entire
-words may be replaced.
-Otherwise
-.Ar %
-is the substring of
-.Ar old_string
-to be replaced in
-.Ar new_string .
-.It Cm :T
-Replaces each word in the variable with its last component.
-.It Cm :tl
-Converts variable to lower-case letters.
-.It Cm :tu
-Converts variable to upper-case letters.
-.It Cm :U
-Converts variable to upper-case letters.
-(deprecated)
-.It Cm :u
-Remove adjacent duplicate words (like
-.Xr uniq 1 ) .
-.El
-.Sh DIRECTIVES, CONDITIONALS, AND FOR LOOPS
-Directives, conditionals, and for loops reminiscent
-of the C programming language are provided in
-.Nm .
-All such structures are identified by a line beginning with a single
-dot
-.Pq Ql \&.
-character.
-The following directives are supported:
-.Bl -tag -width Ds
-.It Ic .include Ar <file>
-.It Ic .include Ar \*qfile\*q
-Include the specified makefile.
-Variables between the angle brackets
-or double quotes are expanded to form the file name.
-If angle brackets
-are used, the included makefile is expected to be in the system
-makefile directory.
-If double quotes are used, the including
-makefile's directory and any directories specified using the
-.Fl I
-option are searched before the system
-makefile directory.
-.It Ic .sinclude Ar <file>
-.It Ic .sinclude Ar \*qfile\*q
-Like
-.Ic .include ,
-but silently ignored if the file cannot be found and opened.
-.It Ic .undef Ar variable
-Un-define the specified global variable.
-Only global variables may be un-defined.
-.It Ic .error Ar message
-Terminate processing of the makefile immediately.
-The filename of the
-makefile, the line on which the error was encountered and the specified
-message are printed to the standard error output and
-.Nm
-terminates with exit code 1.
-Variables in the message are expanded.
-.It Ic .warning Ar message
-Emit a warning message.
-The filename of the makefile,
-the line on which the warning was encountered,
-and the specified message are printed to the standard error output.
-Variables in the message are expanded.
-.El
-.Pp
-Conditionals are used to determine which parts of the Makefile
-to process.
-They are used similarly to the conditionals supported
-by the C pre-processor.
-The following conditionals are supported:
-.Bl -tag -width Ds
-.It Xo
-.Ic .if
-.Oo \&! Oc Ns Ar expression
-.Op Ar operator expression ...
-.Xc
-Test the value of an expression.
-.It Xo
-.Ic .ifdef
-.Oo \&! Oc Ns Ar variable
-.Op Ar operator variable ...
-.Xc
-Test the value of a variable.
-.It Xo
-.Ic .ifndef
-.Oo \&! Oc Ns Ar variable
-.Op Ar operator variable ...
-.Xc
-Test the value of a variable.
-.It Xo
-.Ic .ifmake
-.Oo \&! Oc Ns Ar target
-.Op Ar operator target ...
-.Xc
-Test the target being built.
-.It Xo
-.Ic .ifnmake
-.Oo \&! Oc Ns Ar target
-.Op Ar operator target ...
-.Xc
-Test the target being built.
-.It Ic .else
-Reverse the sense of the last conditional.
-.It Xo
-.Ic .elif
-.Oo \&! Oc Ns Ar expression
-.Op Ar operator expression ...
-.Xc
-A combination of
-.Ic .else
-followed by
-.Ic .if .
-.It Xo
-.Ic .elifdef
-.Oo \&! Oc Ns Ar variable
-.Op Ar operator variable ...
-.Xc
-A combination of
-.Ic .else
-followed by
-.Ic .ifdef .
-.It Xo
-.Ic .elifndef
-.Oo \&! Oc Ns Ar variable
-.Op Ar operator variable ...
-.Xc
-A combination of
-.Ic .else

-.Ic .ifmake .
-.It Xo
-.Ic .elifnmake
-.Oo \&! Oc Ns Ar target
-.Op Ar operator target ...
-.Xc
-A combination of
-.Ic .else
-followed by
-.Ic .ifnmake .
-.It Ic .endif
-End the body of the conditional.
-.El
-.Pp
-The
-.Ar operator
-may be any one of the following:
-.Bl -tag -width "Cm XX"
-.It Cm ||
-Logical
-.Tn OR
-.It Cm &&
-Logical
-.Tn AND ;
-of higher precedence than
-.Sq Ic || .
-.El
-.Pp
-As in C,
-.Nm
-will only evaluate a conditional as far as is necessary to determine
-its value.
-Parentheses may be used to change the order of evaluation.
-The boolean operator
-.Sq Ic !\&
-may be used to logically negate an entire
-conditional.
-It is of higher precedence than
-.Sq Ic && .
-.Pp
-The value of
-.Ar expression
-may be any of the following:
-.Bl -tag -width Ic
-.It Ic defined
-Takes a variable name as an argument and evaluates to true if the variable
-has been defined.
-.It Ic make
-Takes a target name as an argument and evaluates to true if the target
-was specified as part of
-.Nm Ns 's
-command line or was declared the default target (either implicitly or
-explicitly, see
-.Va .MAIN )
-before the line containing the conditional.
-.It Ic empty
-Takes a variable, with possible modifiers, and evaluates to true if
-the expansion of the variable would result in an empty string.
-.It Ic exists
-Takes a file name as an argument and evaluates to true if the file exists.
-The file is searched for on the system search path (see
-.Va .PATH ) .
-.It Ic target
-Takes a target name as an argument and evaluates to true if the target
-has been defined.
-.El
-.Pp
-An
-.Ar expression
-may also be a numeric or string comparison:
-in this case, the left-hand side
-.Ar must be
-a variable expansion, whereas the right-hand side can be a
-constant or a variable expansion.
-Variable expansion is performed on both sides, after which the resulting
-values are compared.
-A value is interpreted as hexadecimal if it is
-preceded by 0x, otherwise it is decimal; octal numbers are not supported.
-.Pp
-String comparison can only use the
-.Sq Ic ==
-or
-.Sq Ic !=
-operators, whereas numeric values (both integer and floating point)
-can also be compared using the
-.Sq Ic > ,
-.Sq Ic >= ,
-.Sq Ic <
-and
-.Sq Ic <=
-operators.
-.Pp
-If no relational operator (and right-hand value) are given, an implicit
-.Sq Ic != 0
-is used.
-However be very careful in using this feature especially
-when the left-hand side variable expansion returns a string.
-.Pp
-When
-.Nm
-is evaluating one of these conditional expressions, and it encounters
-a word it does not recognize, either the
-.Dq make
-or
-.Dq defined
-expression is applied to it, depending on the form of the conditional.
-If the form is
-.Ic .if ,
-.Ic .ifdef
-or
-.Ic .ifndef ,
-the
-.Dq defined
-expression is applied.
-Similarly, if the form is
-.Ic .ifmake
-or
-.Ic .ifnmake ,
-the
-.Dq make
-expression is applied.
-.Pp
-If the conditional evaluates to true the parsing of the makefile continues
-as before.
-If it evaluates to false, the following lines are skipped.
-In both cases this continues until a
-.Ic .else
-or
-.Ic .endif
-is found.
-.Pp
-For loops are typically used to apply a set of rules to a list of files.
-The syntax of a for loop is:
-.Pp
-.Bl -tag -width indent -compact
-.It Ic .for Ar variable Ic in Ar expression
-.It <make-rules>
-.It Ic .endfor
-.El
-.Pp
-After the for
-.Ar expression
-is evaluated, it is split into words.
-The
-iteration
-.Ar variable
-is successively set to each word, and substituted in the
-.Ic make-rules
-inside the body of the for loop.
-.Sh COMMENTS
-Comments begin with a hash
-.Pq Ql #
-character, anywhere but in a shell
-command line, and continue to the end of the line.
-.Sh SPECIAL SOURCES
-.Bl -tag -width Ic
-.It Ic .IGNORE
-Ignore any errors from the commands associated with this target, exactly
-as if they all were preceded by a dash
-.Pq Ql \- .

-.Fl n
-or
-.Fl t
-options were specified.
-Normally used to mark recursive
-.Nm Ns 's .
-.It Ic .NOTMAIN
-Normally
-.Nm
-selects the first target it encounters as the default target to be built
-if no target was specified.
-This source prevents this target from being selected.
-.It Ic .OPTIONAL
-If a target is marked with this attribute and
-.Nm
-cannot figure out how to create it, it will ignore this fact and assume
-the file is not needed or already exists.
-.It Ic .PRECIOUS
-When
-.Nm
-is interrupted, it removes any partially made targets.
-This source prevents the target from being removed.
-.It Ic .SILENT
-Do not echo any of the commands associated with this target, exactly
-as if they all were preceded by an at sign
-.Pq Ql @ .
-.It Ic .USE
-Turn the target into
-.Nm Ns 's
-version of a macro.
-When the target is used as a source for another target, the other target
-acquires the commands, sources, and attributes (except for
-.Ic .USE )
-of the
-source.
-If the target already has commands, the
-.Ic .USE
-target's commands are appended
-to them.
-.It Ic .WAIT
-If special
-.Ic .WAIT
-source appears in a dependency line, the sources that precede it are
-made before the sources that succeed it in the line.
-Loops are not being

-.El
-.Sh SPECIAL TARGETS
-Special targets may not be included with other targets, i.e., they must be
-the only target specified.
-.Bl -tag -width Ic
-.It Ic .BEGIN
-Any command lines attached to this target are executed before anything
-else is done.
-.It Ic .DEFAULT
-This is sort of a
-.Ic .USE
-rule for any target (that was used only as a
-source) that
-.Nm
-cannot figure out any other way to create.
-Only the shell script is used.
-The
-.Ic .IMPSRC

-to the target's own name.
-.It Ic .END
-Any command lines attached to this target are executed after everything
-else is done.
-.It Ic .IGNORE
-Mark each of the sources with the
-.Ic .IGNORE
-attribute.
-If no sources are specified, this is the equivalent of specifying the
-.Fl i
-option.
-.It Ic .INCLUDES
-A list of suffixes that indicate files that can be included in a source
-file.
-The suffix must have already been declared with
-.Ic .SUFFIXES ;
-any suffix so declared will have the directories on its search path (see
-.Ic .PATH )
-placed in the
-.Va .INCLUDES
-special variable, each preceded by a
-.Fl I
-flag.
-.It Ic .INTERRUPT
-If
-.Nm

-.It Ic .LIBS
-This does for libraries what
-.Ic .INCLUDES
-does for include files, except that the flag used is

-.It Ic .MAIN
-If no target is specified when
-.Nm
-is invoked, this target will be built.
-This is always set, either

-The flags are as if typed to the shell, though the
-.Fl f
-option will have
-no effect.
-Flags (except for
-.Fl f )
-and variable assignments specified as the source
-for this target are also appended to the
-.Va .MAKEFLAGS
-internal variable.
-Please note the difference between this target and the
-.Va .MAKEFLAGS
-internal variable: specifying an option or variable

-(Note this disables the
-.Dq Remaking Makefiles
-feature.)
-.It Ic .PRECIOUS
-Apply the
-.Ic .PRECIOUS

-If no sources are specified, the
-.Ic .PRECIOUS
-attribute is applied to every
-target in the file.
-.It Ic .SHELL
-Select another shell.
-The sources of this target have the format
-.Ar key Ns = Ns Ar value .
-The
-.Ar key
-is one of:
-.Bl -tag -width ".Va hasErrCtl"
-.It Va path
-Specify the path to the new shell.
-.It Va name
-Specify the name of the new shell.

-other name.
-.It Va quiet
-Specify the shell command to turn echoing off.
-.It Va echo
-Specify the shell command to turn echoing on.
-.It Va filter
-Usually shells print the echo off command before turning echoing off.
-This is the exact string that will be printed by the shell and is used
-to filter the shell output to remove the echo off command.
-.It Va echoFlag
-The shell option that turns echoing on.
-.It Va errFlag
-The shell option to turn on error checking.
-If error checking is on, the shell should exit if a command returns
-a non-zero status.
-.It Va hasErrCtl
-True if the shell has error control.
-.It Va check
-If
-.Va hasErrCtl
-is true then this is the shell command to turn error checking on.
-If
-.Va hasErrCtl
-is false then this is a command template to echo commands for which error
-checking is disabled.
-The template must contain a
-.Ql %s .
-.It Va ignore
-If
-.Va hasErrCtl
-is true, this is the shell command to turn error checking off.
-If
-.Va hasErrCtl
-is false, this is a command template to execute a command so that errors
-are ignored.
-The template must contain a
-.Ql %s .
-.It Va meta
-This is a string of meta characters of the shell.
-.It Va builtins
-This is a string holding all the shell's builtin commands separated by blanks.
-The
-.Va meta
-and
-.Va builtins
-strings are used in compat mode.
-When a command line contains neither a meta
-character nor starts with a shell builtin, it is executed directly without
-invoking a shell.
-When one of these strings (or both) is empty all commands are executed
-through a shell.
-.It Va unsetenv
-If true, remove the
-.Ev ENV
-environment variable before executing any command.
-This is useful for the Korn-shell
-.Pq Nm ksh .
-.El
-.Pp
-Values that are strings must be surrounded by double quotes.
-Boolean values are specified as

-keyword.
-It is also possible to modify the parameters of the builtin shell by just
-specifying other keywords (except for
-.Va path ) .
-.It
-Using another executable for one of the builtin shells.
-This is done by specifying the path to the executable with the
-.Va path
-keyword.
-If the last component is the same as the name of the builtin shell, no
-name needs to be specified; if it is different, the name must be given:

-selects the builtin shell

-.Pa /usr/local/bin/sh .
-Like in the previous case, it is possible to modify parameters of the builtin
-shell by just specifying them.
-.It
-Using an entirely different shell.
-This is done by specifying all keywords.
-.El
-.Pp
-The builtin shells are
-.Dq Li sh ,
-.Dq Li csh

-.Dq Li ksh .
-Because

-it is unwise to specify

-.It Ic .SILENT
-Apply the
-.Ic .SILENT
-attribute to any specified sources.
-If no sources are specified, the
-.Ic .SILENT
-attribute is applied to every
-command in the file.
-.It Ic .SUFFIXES
-Each source specifies a suffix to
-.Nm .
-If no sources are specified, any previous specified suffixes are deleted.
-.It Ic .WARN
-Each source specifies a warning flag as previously described for the
-.Fl x
-command line option.
-Warning flags specified on the command line take precedence over flags
-specified in the makefile.
-Also, command line warning flags are pushed to sub-makes through the
-.Ev MAKEFLAGS
-environment variables so that a warning flag specified on the command
-line will influence all sub-makes.
-Several flags can be specified on a single
-.Ic .WARN
-target by separating them with blanks.
-.El
-.Sh REMAKING MAKEFILES
-If the special target
-.Ic .MAKEFILEDEPS
-exists in the Makefile,
-.Nm
-enables the
-.Dq Remaking Makefiles
-feature.
-After reading Makefile and all the files that are included using
-.Ic .include
-or
-.Ic .sinclude
-directives (source Makefiles)
-.Nm
-considers each source Makefile as a target and tries to rebuild it.
-Both explicit and implicit rules are checked and all source Makefiles
-are updated if necessary. If any of the source Makefiles were rebuilt,
-.Nm
-restarts from clean state.
-.Pp
-To prevent infinite loops the following source Makefile targets are ignored:
-.Bl -bullet
-.It
-.Ic ::
-targets that have no prerequisites
-.It
-.Ic \&!
-targets
-.It
-targets that have
-.Ic .PHONY
-or
-.Ic .EXEC
-attributes
-.It
-targets without prerequisites and without commands
-.El
-.Pp
-When remaking a source Makefile options
-.Ic -t
-(touch target),
-.Ic -q
-(query mode), and
-.Ic -n
-(no exec) do not take effect, unless source Makefile is specified
-explicitly as a target in
-.Nm
-command line.
-.Pp
-Additionally, system makefiles and
-.Ic .depend
-are not considered as Makefiles that can be rebuilt.
-.Sh ENVIRONMENT
-The
-.Nm
-utility uses the following environment variables, if they exist:
-.Ev MACHINE ,
-.Ev MAKE ,
-.Ev MAKEFLAGS ,
-.Ev MAKEOBJDIR ,
-.Ev MAKEOBJDIRPREFIX ,
-and
-.Ev MAKESYSPATH .

-Older versions of

-instead of
-.Ev MAKEFLAGS .
-This was removed for
-.Tn POSIX
-compatibility.
-The internal variable
-.Va MAKE
-is set to the same value as
-.Va .MAKE ;
-support for this may be removed in the future.
-.Pp
-The use of the
-.Cm :L
-and
-.Cm :U
-modifiers are deprecated
-in
-.Fx 10.0
-and the more portable (among Pmake decedents)
-.Cm :tl
-and

-.Sh HISTORY
-A
-.Nm
-command appeared in PWB UNIX.
-.Sh BUGS
-The determination of
-.Va .OBJDIR
-is contorted to the point of absurdity.
-.Pp
-In the presence of several
-.Ic .MAIN
-special targets,
-.Nm
-silently ignores all but the first.
-.Pp
-.Va .TARGETS
-is not set to the default target when
-.Nm
-is invoked without a target name and no
-.Ic .MAIN
-special target exists.
-.Pp
-The evaluation of
-.Ar expression
-in a test is very simple-minded.
-Currently, the only form that works is
-.Ql .if ${VAR} op something .
-For instance, you should write tests as
-.Ql .if ${VAR} == "string"
-not the other way around, which would give you an error.
-.Pp
-For loops are expanded before tests, so a fragment such as:
-.Bd -literal -offset indent
-\&.for ARCH in ${SHARED_ARCHS}
-\&.if ${ARCH} == ${MACHINE}
- ...
-\&.endif
-\&.endfor
-.Ed
-.Pp
-will not work, and should be rewritten as:
-.Bd -literal -offset indent
-\&.for ARCH in ${SHARED_ARCHS}
-\&.if ${MACHINE} == ${ARCH}
- ...
-\&.endif
-\&.endfor
-.Ed
-.Pp
-The parsing code is broken with respect to handling a semicolon
-after a colon, so a fragment like this will fail:
-.Bd -literal -offset indent
-HDRS= foo.h bar.h
-
-all:
-\&.for h in ${HDRS:S;^;${.CURDIR}/;}
- ...
-\&.endfor
-.Ed
-.Pp
-A trailing backslash in a variable value defined on the command line causes
-the delimiting space in the
-.Ev MAKEFLAGS
-environment variable to be preceded by that backslash.
-That causes a submake to not treat that space as a word delimiter.
-Fixing this requires a larger rewrite of the code handling command line
-macros and assignments to
-.Va .MAKEFLAGS .

- *
- * Suff_ClearSuffixes Clear out all the suffixes and defined
- * transformations.
- *
- * Suff_IsTransform Return TRUE if the passed string is the lhs
- * of a transformation rule.

- * Suff_GetPath Return the search path for the given suffix.
