Are you able to run loch from gdb and find out source code line where it fails? I have a suspicion, that it may be off-screen rendering stuff that is doing problems. It is initialized when loch starts. On some machines (especially linux with intel graphic cards), it segfaults when I try to render off-screen, but may be on some other, it can not even initialize. Especially when you are able to run all wx open-gl samples. Regards, S. On Tue, May 5, 2009 at 5:47 AM, Martin Luethi <luethi@vaw.baug.ethz.ch> wrote:

Had was bugging the mailing list about the loch segfault more than a year ago. I never could resolve it, and nobody else could. There was some indication that this might be due to some Intel Graphics card driver problem.
Your strace looks very much like mine, and there was this "resource temporarily unavailable" that might be the culprit. Somehow some X capability (DRI) cannot be accessed.
Once upon a time everything worked perfectly, but never since then. If you have any ideas how to further debug that I would be glad to hear that. Since I am not a graphics person I have now clue how to fix that. Also, all wx examples and other wx applications worked nicely, so that I am not shure whether wx is used in a wrong way.
Maybe valgrind could help, but I havn't done that yet.
Best, Martin
