2383 :: Error when using openGL with X11

  I've tried to copy this into nim, produced this code . It compiles without problem but when I'm trying to execute it throws:

  
  Traceback (most recent call last)
  test.nim(59)             test
  opengl.nim(2380)         glEnable
  SIGSEGV: Illegal storage access. (Attempt to read from nil?)
  Run

  It does not seem to miss any dll, yet it can't call gl methods. I've tried openGL glut example from repo and it worked succesfully. I can't call myself expert at openGL, but C code worked. Does anyone of you have idea where the problem may lie so I can fix it?

  try adding the loadExtensions proc before calling any opengl function. Since the example does work, you can incrementally transform the working example into what you are trying to do, and see what you were missing, as soon as a change breaks the code.

  loadExtensions worked. I've seen something about that function, but looked at it and thought: Meh, can't be just that. I see now that example calls it too before any gl* methods. Anyway, thanks for help ;] Cheers.
