New subject: [trinity-devel] kdebase SVN FTBFS under Fedora15

26 Oct 2011


      Hello, I have some troubles compiling kdebase SVN 1260891 on Fedora 15.
I guess this is because the "direct linking" is now disabled by default 
on this distro.

To sum up things, I can compile if I set the following variable
export LDFLAGS="-ldl -lXext"
