A sample program for drawing things on X windows from lisp is included in the file gcl/lsp/littleXlsp.lsp
That routine invokes the corresponding C routines in XLIB. So in order to use it you must ‘faslink’ in the X routines. Directions are given at the beginning of the lisp file, for either building them into the image or using faslink.
This program is also a good tutorial on invoking C from lisp.
See also defentry and faslink.
