I have been trying to use GLIntercept (version 0.5) to track down a
rendering problem. I have used this tool successfully many times in the
past. However I have now moved to a Visual Studio Express 2008 (VC9.1)
build environment and I am encountering some problems. I rebuilt
GLIntercept for the VC9.1 environment, and updated my installation as I
have done a number of times in the past (copy the latest DLL into the
directory my app loads from). However when I run my app which is built
using OSG 2.8.2, the OSG runtime reports "Warning: detected OpenGL
error 'invalid operation' after RenderBin::draw(,)" on every frame,
this does not occur when the normal OpenGL library is used. Has any else observed this behaviour? GLIntercept also logs a number of "GLI | GL ERROR - Function wglGetPixelFormat generated error 0x0502" which seem to be as a result of a wglGetPixelFormat call from within the nVidia opengl driver interface layer. These may be something to do with my rendering problem. However it is difficult to decide what to track down due to the fact the GLIntercept itself seems to be introducing errors. Any ideas? Roger |
