Dear CommonQT gurus,

trying to make my first steps using CommonQt. I downloaded and installed as per instructions on http://kvardek-du.kerno.org/2011/12/setting-up-commonqt-on-osx.html . No luck, though.

I have the following code: http://paste.lisp.org/+31SQ

This tries to load CommonQt ... and fails with:

The last debug info is indicating that find-qclass does not find the class ;-) Well, obvious question: Why?

I am used to the style warnings from SBCL - I never had problems using foreign libs despite the warning messages!

I'm not sure what pushed you towards defining your own CFFI libraries for libsmoke and loading them. That was neither necessary, nor performed in the right way.

All you need is (ql:quickload :qt)

(qt:ensure-smoke :qtcore) (qt:ensure-smoke :qtgui)

(or just (qt:make-qapplication), when you are actually writing a program, or even qt:with-main-window)
