Hello, I am rather new to lisp and have been learning by reading "Practical Common Lisp" online and "Land of Lisp". One thing I was just sort of interested in was seeing how you could use lisp to make GUIs. So, I decided to try McCLIM. Anyway, I use gentoo, so I just emerged mcclim and have version 0.9.6. I am using the clisp implementation and think I have everything set up correctly. Following the instructions on the cliki, I can do the following: (asdf:oos 'asdf:load-op :mcclim) - ends with 0 errors, 74 warnings NIL - so I think that is ok. Since I am using gentoo, I didn't do the ln -s mcclim/clim-examples.asd . since I am just using the stock directories. Then I can run: (asdf:oos 'asdf:load-op :clim-examples) - ends with 0 errors, 0 warnings NIL - so that seems ok as well. The problem is when I run: (clim-demo::run-test 'clim-demo::demodemo) I get: *** - Connection failure to X11.0 server display 0: No protocol specified I have clx installed - I also ran (asdf:oos 'asdf:load-op :clx) to ensure everything was built. If I build / load the gtkairo backend: (asdf:oos 'asdf:load-op :clim-gtkairo) Then the demos appear to run. I am sure I am doing something wrong - does anyone know what it might be though? Thanks! -C
