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 -lX1
-lX11
ld: library not found for -lX1
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
