Created attachment 3359 output of lshal and make no problem with ./configure but i get this error when i do make: /usr/bin/ld: ../../common/.libs/libxfpmcommon.a(libxfpmcommon_la-xfpm-brightness.o): undefined reference to symbol 'XFlush' /usr/bin/ld: note: 'XFlush' is defined in DSO /usr/lib64/libX11.so.6 so try adding it to the linker command line /usr/lib64/libX11.so.6: could not read symbols: Invalid operation here http://fedoraproject.org/wiki/UnderstandingDSOLinkChange there is a good hint of how to solve it but it's too much for me.... the complete output of make and the output of lshal are in the attacments.
