Hi Andreas :

Is Windows XP "true windows?"
I meant "not emulated" in VMware or something.
I can confirm your problem on one desktop: both the programs hangs, in both release and debug builds. On my laptop, that has an older OpenGL driver that does not support GL_EXT_framebuffer_object, the command osgprerender cow.os is working.
Hello Luigi,

thank you very much for this confirmation. I thought that I was going nuts ...

So this is a real bug, probably a bug of mingw rather than OSG.

I' ve compiled them with my CMake builds, so could be slitly differnet of what you have used, but the problem seem the same. I can start a fresh build with MSVC, VS7.1, but I' m pretty sure it will work I' ve used DevCpp installation as a basis for mingw/msys build. I' m not a MINGW expert, but I like the fact is an open source compiles under windows
I use it because this way I can use the same compiler on all platforms.
When I have time, I' ll try to use Devccpp to debug the project that is not working.
That would be good. I really tried to debug it with gdb, but either the crash was so bad that gdb crashed, too, or the stacktrace contained an infinite loop. Probably you will get the same problems, as DevCPP uses gdb.

The CMake build system is still under dev, but if you are interested in using/helping, let me know
You probably have good reasons to do this, and I wish you the best luck for it, but I personally think that the make-system of osg works pretty well and thus have no reason to use a different one.

Really thanks a lot for this reply, now I feel less alone in this world!

Regards,

Andreas
