HI Mohammed, The trace points to the OpenGL driver failing when trying to create the pbuffer.
osgdem uses an OpenGL graphics context to create the GL compressed textures, you can avoid the use of the GL driver if you using NVTT. To use this you'll need to install NVTT SDK and rebuild VPB against it. When running osgdem you'll need to add the --compressor-nvtt command line option to tell osgdem to use NVTT. Alternatively you could avoid use of OpenGL compressed textures by using the --RGB-24 command option. Or... just install an non broken OpenGL driver. Robert.
