I am not sure what program configure is trying to build here, but I bet that libX11.so contains those undefined references / does not link against libxcb.so. Can you compile other programs against this libX11.so?

Can you try compiling that program? Does it work? Cheers, Uli -- "Every once in a while, declare peace.
