[osg-users] glGetString returning NULL

[sherman wilcox]

Running latest version of OSG in SVN, calling glGetString(...) from
main render loop (single threaded osgViewer). Like this:

  while(viewer.done() == false)
  {
    viewer.frame();

    char* extensions = (char*)glGetString(GL_EXTENSIONS);
  }


extensions is always NULL. Am I doing something wrong here? Could
someone else test this?
