[cells-gtk-devel] (test-gtk:gtk-demo) failed

The demo now works, and displays the GTK  Testing window and tabs.
Everything in the demo seems to be working okay, as far as I can tell,
though it still prints some warning messages at the shell.

So, it's all fixed. Thanks for your help.

This is interesting.  At this point I am pretty sure your problem is not  
with cells-gtk, but rather with the underlying cffi.  It looks like the  
definitions of the gtk libs don't pass compilation properly, and the fact  
that you keep getting the NIL function error both suggest that the binding  
to the library does not work at all.

So let us investigate your CFFI:

- Did you install cffi 0.9.2 from here?
http://common-lisp.net/project/cffi/
(The darcs version *and* older versions don't work!)

- Do you have clisp >= 2.35 as required by cffi (cf. their homepage)

I don't know how clisp handles compilation of source files .  SBCL creates  
compiled files with the extension .fasl, and sometimes you need to remove  
those manually, because otherwise the compiler uses outdated files.
