G'day,
In case I'm not the only one who didn't know this, the current SVN version will only compile against the current Fedora 13 stable if you explicitly tell it to link an extra library (libX11).
This is what you get with a standard autogen.sh / make:
/usr/bin/ld: ui_utils.o: undefined reference to symbol 'XFree' /usr/bin/ld: note: 'XFree' 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
Running the following from the shell before config and compile fixes this:
export LDFLAGS=-lX11
This is why:
