A real life example just poped-up today where the PKG_CONFIG variable is used. I am also fixing the 76 other modules where "pkg-config" is hard-coded. <BLOCKQUOTE> <PRE> <TT># To test each version, you'll want to just build it over your MacPorts:</TT> <TT>export CPPFLAGS=-I/opt/local/include -I/path/to/macports/dports/x11/xorg-server-devel/files/dri</TT> <TT>export PKG_CONFIG=/opt/local/bin/pkg-config</TT> </PRE> </BLOCKQUOTE> Reviewed by: <A HREF="http://lists.x.org/archives/xorg-devel/2009-December/004290.html">http://lists.x.org/archives/xorg-devel/2009-December/004290.html</A> On Sun, 2009-12-20 at 14:41 -0500, Gaetan Nadon wrote: <BLOCKQUOTE TYPE=CITE> Hi, This is a preventive maintenance patch to fix a dormant bug. It is intended for the git master branch. The xorg-server macro  XORG_DRIVER_CHECK_EXT() uses the hard-coded executable name "pkg-config" (without a path) rather than the variable PKG_CONFIG which is defined during configuration: <BLOCKQUOTE> <TT>checking for pkg-config... /usr/bin/pkg-config</TT> <TT>checking pkg-config is at least version 0.9.0... yes</TT> </BLOCKQUOTE> The user is invited to overwrite the value of PKG_CONFIG if need be. This feature will only work if all invocation of this program is done through PKG_CONFIG variable. All driver modules use this macro.
