pkg-config is a script to make putting together all the build
|
|
flags when compiling/linking a lot easier.
|
|
|
|
Report bugs at http://bugzilla.freedesktop.org/
|
|
|
|
To use pkg-config, do something like the following in your configure.ac
|
|
|
|
PKG_CHECK_MODULES([GNOME], [gtk > 1.2.8 gnomeui >= 1.2.0])
|
|
|
|
This puts the neccesary include flags to compile/link something against
|
|
libgnomeui and all its dependencies in $(GNOME_CFLAGS), and the -L/-l flags
|
|
for linking in $(GNOME_LIBS).
|
|
|
|
Users can define the PKG_CONFIG environment variable to point at the
|
|
right one, or if they cross-compile and have a correctly named pkg-config
|
|
(eg. arm-linux-pkg-config) in their PATH that will be used in preference.
|
|
|
|
Users can also define the GNOME_CFLAGS and GNOME_LIBS environment variables
|
|
if they think they know better, pkg-config will not be called if they do
|
|
that.
|
|
|
|
The "gtk > 1.2.8" part is only neccesary if you want to specifically check
|
|
if libgtk is version 1.2.8 or higher. Otherwise, the flags for gtk
|
|
will be included automatically, since libgnomeui depends on gtk.
|
|
So you could just say:
|
|
|
|
PKG_CHECK_MODULES([GNOME], [gnomeui])
|
|
|
|
for any version of gnomeui.
|
|
|
|
For more info, there's even a man page, try 'man pkg-config'

Building
|
|
========
|
|
pkg-config depends on glib. Note that glib build-depends on pkg-config,
|
|
but you can just set the corresponding environment variables (ZLIB_LIBS,
|
|
ZLIB_CFLAGS are the only needed ones when this is written) to build it.
|
|
|
|
pkg-config also either needs an earlier version of itself to find glib
|
|
or you need to set GLIB_CFLAGS and GLIB_LIBS to the correct values for
|
|
where it's installed in your system.
|
|
|
|
If this requirement is too cumbersome, a bundled copy of a recent glib
|
|
stable release is included. Pass --with-internal-glib to configure to
|
|
use this copy.
|
|
|
|
If you're cross-compiling and you need to build the bundled glib, refer
|
|
to the glib documentation for cross-compiling glib. In short, this will
|
|
require setting some autoconf cache variables in cases where glib would
|
|
need to run a program to determine the correct value. See the glib
|
|
documentation:
|
|
|
|
http://developer.gnome.org/glib/stable/glib-cross-compiling.html
|
|
|
|
If you need to use the bundled glib on Mac OS X, you'll most likely need
|
|
to build for a single architecture rather than as a universal binary.
|
|
This is because glib (as of version 2.32) does not support building for
|
|
multiple architectures out of the box. The glib2 from MacPorts or
|
|
Homebrew may be available as a universal binary and usable for
|
|
pkg-config as described above. Nothing in pkg-config itself precludes
|
|
being built as a universal binary.
