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 -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
