Crash on Quit

[Gavin]

My app works fine and runs as it should, but when quitting it it crashes and kills all around it! Is this ogl/glut having problems cleaning up memory? Anyone else had these probs?

Easiest thing to do is start with a basic GLUT app from the SDK (like glutmech). We know it doesn't crash, so it's most likely not a GLUT prob.

Then, using this code as a starting point, add your code bit by bit, and test incrementally. As soon as your app starts killing things on quit, then you'll have a better idea of what code caused the mishap.

I get dumped into the depths of the ATI driver code in Macsbug whenever I exit several of the Mac OpenGL SDK demo apps. You are not alone )

I too have experienced these problems, ie big time crash when quiting a glut based program from menubar

It only happens if I choose quit from the menubar. If I provide a "hit Q to quit" keyboard routine and exit(0) in that routine, everything works fine.

Any better solutions/workarounds?

I may have figured it out. I noticed that the one of the glut based examples I had that worked included a line after glutCreateWindow("colorcube")

glutIdleFunc(NULL);

adding this to my crahsing sample fixed it. Other examples I had that worked passed the display function in glutIdleFunc, ie glutIdleFunc(myDisplay)

hope that helps

I am using an Idle Function though, not the display, but some other processing stuff. Anyone get any interesting error logs with it?

I installed Mac OS X (Japanese language version) few days ago. Then my glut app began to crush on quit on Mac OS 9.0.4. The app ran fine before.
Mac OS X Installer adds/replaces some system files and OpenGL library(s) in the extension folder of Mac OS 9 for 'Classic environment compatibility'.
I uninstalled Mac OS X, and restored all replaced system files in Mac OS 9.0.4 system folder.
Now my glut app runs fine.

This is my case.
I use CodeWarrior 6.

Mybe it as I did have mac osx, and have removed it, maybe a os reinstall might help...

i'll let you know

[Gavin]

Well, just compiled on unix/irix to see whats going on a bit better, no crash, no xmesa error message, no error log. Then recomile on mac, run, quite, RESTART, arrgghh

I assume that you are all on the mac-opengl mailing list. It appears that it was the classic rave that was causing my app to die on quit, as it is know fine, and happy....
