So ... After having spent the better part of this day getting CommonQt to tun on OS X there's a couple of points to note: Do not follow any other info than that on CommonQt's Homepage. It will cause you trouble, especially if you are on OS X. ;-) The other point is related to the thread challenge I encountered. And yes, multi-threaded SBCL is able to run CommonQt on OS X if 1. You change file repl-integration.lisp line 106 from "initial thread" to "main thread" and recompile and reload the qt package. 2. You don't use Slime to interact with your REPL. The second is a real PITA. So I tried digging up a solution. The qt-repp package seemed the right thing to use. Nope: (ql:quickload :qt-repl) (qt-repl:start-gui-thread) Lisp output: WARNING: QApplication was not created in the main() thread. Using qt-repl:eval-in-gui-thread (with the mods described above) then tries to execute the evaluation in the guy thread. But no, this doesn't work: Lisp output: QCoreApplication::exec: The event loop is already running Slime repl output: CL-USER> (qt-repl:eval-in-gui-thread (qt-conv:main)) -1 and that's where I am stuck now. Further digging or suggestions are in order ;-) Thanks to Stas and Ivan for the support so far! Regards Frank

[Commonqt-devel] Qt Tutorial: Memory Fault

Me again ... Doing (ql:quickload :qt) (qt:ensure-smoke :qtcore) (qt:ensure-smoke :qtgui) (ql:quickload :qt-tutorial) and finally (qt-conv:main) results in the following errors: SBCL error output: http://paste.lisp.org/+31SS SBCL backtrace: http://paste.lisp.org/+31ST Ok, so maybe I am running into issues as described on "Known issues", "Callbacks from threads" - am I? Thanks again for looking at this. Regards Frank

Make sure that libsmoke and >libcommonqt were compiled and are using the same version of Qt. Maybe I'm misinterpreting something, but this line 1: ("foreign function: call_into_lisp") from the backtrace as shown in the lisp paste is a callback from C to Lisp for me. And right in that function hell starts ... To be honest I haven't looked at the sources of Qt yet (I don't have them installed as my disk space is a scarce resource). I am still hoping for someone having had the same problem. Thanks again for helping out. Kind regards Frank

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 .

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