Bug 32905 – HOpenGL programs compiled with ghc 6.0.1 crash.

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Anatoli Tubman 2003-11-06 13:55:51 UTC]

When I try to run example HOpenGL programs from
http://www.tfh-berlin.de/~panitz/hopengl/examples/klassen.html, they exit with
segfault.

Reproducible: Always
Steps to Reproduce:
1. Download http://www.tfh-berlin.de/~panitz/hopengl/examples/src/APolygon.hs
2. ghc --make APolygon -o APolygon
3. ./APolygon

Actual Results:  
Segmentation fault

Expected Results:  
Run APolygon :)

(It works with ghc 6 on my Solaris box at work)

The program crashes in glClear(). Tracebacks are irrelevant with ghc so I'm not
including one.

I will try to have a look at this -- however, I do not have much experience
with HOpenGL myself. Do you have any idea what might be causing this, i.e.
if it has something to do with the Gentoo ebuild or might be a general problem
with the Linux version of GHC?

[Comment 2 Andres Loeh (RETIRED) 2004-01-05 14:01:49 UTC]

Dou you have the same problem with GHC 6.2?

I have not heard anything, and it seems to work for others, so I am closing this for now.

Please reopen the bug if you still experience problems.
