Hi,

I'd like to profile a GLUT application. After a run of the application with the +RTS -p flag, the .prof file is actually created but is always empty.

Does someone have a clue of what's going on? Would it be related to my application calling GLUT's leaveMainLoop to exit?

Yes, the problem is the default behavior of leaveMainLoop. Setting actionOnWindowClose $= MainLoopReturns does the trick. Cheers, Thu
