Question

I am using GCC, what switches do I need to add to link with Xlib? After searching, all I could find was -lX11, but that gave me ld: library not found for -lX11

I am using a mac (10.6), but I would not like anything that is Mac specific.

Answer 1

You can usually use pkg-config to determine the flags you need to pass:

gcc my-program.c $(pkg-config --cflags --libs x11) -o my-program
