This document assumes that you already know how port system works, and therefore only provides GNOME-specific hints and tips. General instructions can be found in the FreeBSD Porter's Handbook.

GNOME Makefile Macros

For ports that require GNOME, you should define the following in your port's Makefile:

 USE_GNOME=	yes
 USE_X_PREFIX=	yes

These will take care of the install prefix and requiring all the core GNOME dependencies. If your port can use GNOME, but it isn't required, you can define the following in your Makefile:

 WANT_GNOME=	yes

If the user has defined WITH_GNOME in their /etc/make.conf then GNOME components will be built. Other useful GNOME-related macros that can be define in your port's Makefile include:

  • USE_GLIB (WANT_GLIB) : The application requires (can use) Glib. Defining USE_GNOME or USE_GTK takes care of this option automatically.

  • USE_GTK (WANT_GTK) : The application may not be GNOME-compliant, but requires GTK+ widgets. This will take care of those dependencies. Note, this option should not be defined if USE_GNOME is defined.

  • USE_ESOUND (WANT_ESOUND) : The application requires (can use) esound. Normally, esound support is added by specifying USE_GNOME.

  • USE_IMLIB (WANT_IMLIB) : The application requires (can use) the Imlib image library. This is not needed if USE_GNOME is defined.

  • USE_GNOMELIBS (WANT_GNOMELIBS) : The application requires (can use) GNOME libraries. This does not import as many dependencies as USE_GNOME and should be used for applications that use GNOME, but do not need the GNOME Control Center, the GNOME capplet library, or anything from the GNOME Core.

  • USE_GNOMECTRL (WANT_GNOMECTRL) : The application requires (can use) all the GNOME libraries and the GNOME Control Center, but does not use anything from GNOME Core. This option is usually used for backend APIs.

When building GNOME ports, remember that many applications + require shared directories in ${PREFIX}/share/gnome. Ports + should be constructed in a way such that files placed in these + directories are removed before the package which created the + directories (i.e. the package that has an appropriate + @dirrm in its pkg-plist). For GNOME, the principle + parent port is gnomecore. If your port incudes + USE_GNOME= yes you should be fine. If you're + uncertain if you need to require any other packages, you can use + the script ${PORTSDIR}/Tools/scripts/gnomedepends.py + to examine your port's pkg-plist.

To see a list of what packages your port will actually require, + use the command make package-depends.

GNOME Internationalization

GNOME relies on the gettext port to do internationalization (I18N). FreeBSD currently supports two versions of gettext: 0.10.35 and 0.10.40. Most ports can use 0.10.35. However, if, when compiling your port, you get an error building the .po translation files similar to the following you will need to use the newer version of gettext:

 /usr/local/bin/msgfmt -o zh_TW.mo zh_TW.po
 zh_TW.po:255: end-of-line within string
 zh_TW.po:912: illegal control sequence
 zh_TW.po:2806: end-of-line within string
 zh_TW.po:2856: end-of-line within string
 zh_TW.po:2879: illegal control sequence
 zh_TW.po:2982: end-of-line within string
 found 6 fatal errors

To use the newer gettext, add the following to your port's Makefile:

 BUILD_DEPENDS=  msgfmt-new:${PORTSDIR}/devel/gettext-devel
 CONFIGURE_ENV+= MSGFMT=${LOCALBASE}/bin/msgfmt-new \
 				XGETTEXT=${LOCALBASE}/bin/xgettext-new

When installing GNOME applications, make sure the translation files are put in /usr/X11R6/share/locale and not /usr/X11R6/share/gnome/locale. To do this, add the following to your port's Makefile's pre-patch: section:

 pre-patch:
 	@find ${WRKSRC} -name "Makefile.in*" | xargs ${PERL} -pi -e \
 		's|\$\(datadir\)/gnome/|\$\(datadir\)/|g ; \
 		 s|\$\(datadir\)/locale|\$\(prefix\)/share/locale|g'

Also, make sure the translation files are installed as .mo files and not .gmo files. To do this, you can generally use this patch.

If your port depends on iconv, make sure you substitute all instances of iconv.h with giconv.h, and all instances of -liconv with -lgiconv.

Libtool Issues

Most if not all GNOME applications depend on GNU's libtool. They also use the GNU configure system. Newer versions of libtool have a problem with FreeBSD's USE_LIBTOOL macro. Use of this macro should be avoided. Instead, set GNU_CONFIGURE= yes, and use the following patch to prevent the installation of .la files.

The more ported applications we have, the better.
