Well. Even pretty fundamental GNOME stuff like gtk2-devel is still broken. Look here:
[root@localhost ~]# pkg-config --libs gtk+-2.0 -pthread -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lgdk_pixbuf-2.0 -lpangocairo-1.0 -lcairo -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lrt -lglib-2.0
-lX11 is missing (at least, maybe more). Any gtk app using pkg-config to figure which libraries are required fails to build now.
Only if the library you are compiling actually uses any libX11 APIs. If it only uses APIs from the named libraries, it will link fine.
Sure? For the libpng case I have a build failure which looks like this isn't the case (bug 565047):
<quote> /usr/bin/ld: /usr/lib/gcc/i686-redhat-linux/4.4.3/../../../libpng12.so: undefined reference to symbol 'crc32' /usr/bin/ld: note: 'crc32' is defined in DSO /lib/libz.so.1 so try adding it to the linker command line </quote>
Which made me think -lz is needed on the command line even if zlib is used only indirectly via libpng (and likewise that -lX11 should be there for gtk2 because gtk2 needs it).
cheers, Gerd
