Hi,
I haven't heard of problems like you describe, I would certainly
suspect a driver or build issue though. Do you have a stack trace?
Not yet, I usually use the release-version. I will try to track this
down.
I have now built debug-libraries. I don´t get a valid statcktrace, when
entering backtrace in gdb I am now at frame nr. 3 000 000, still running ...
I still have the feeling that this is some mingw / opengl issue, because
it only happens when it comes to newer opengl-stuff. I´d really hope
someone with more mingw-experience than myself could comment on this.
I cannot generate an implib from the opengl32.dll, because it has no
symbols in it.
Regards,
Andreas
Do pbuffer and frame buffer RTT work? i.e.
osgprerender cow.osg --pbuffer
This works good.
osgprerender cow.osg --fb
This works, but slow!
osgprerender cow.osg --fbo
This crashes. The output with notify-level debug is:
OpenGL extension 'GL_EXT_framebuffer_object' is supported.
OpenGL extension 'GL_ARB_vertex_program' is supported.
OpenGL extension 'GL_ARB_fragment_program' is supported.
OpenGL extension 'GL_ARB_shader_objects' is supported.
OpenGL extension 'GL_ARB_vertex_shader' is supported.
OpenGL extension 'GL_ARB_fragment_shader' is supported.
OpenGL extension 'GL_ARB_shading_language_100' is supported.
glVersion=2, isGlslSupported=YES, glslLanguageVersion=1.1
Setting up osg::CameraNode::FRAME_BUFFER_OBJECT
I suspect that there is an incompatibility with the mingw-lib and the
microsoft-dll. I will try to generate the implib from the dll myself.
It would be really nice if other mingw-users could comment on this.
Regards,
Andreas
