    Okay I found the answer in a book for perl. Obviously packing the arrays or giving reference isnt good enough
    glMaterialfv_p(GL_FRONT, GL_SPECULAR, 1, 1, 1, 1); glMaterialfv_p(GL_FRONT, GL_SHININESS, 50); glLightfv_p (GL_LIGHT0, GL_POSITION, 1, 1, 1, 0);
    did the trick
      Hi, I'm using the latest SVN rev from New Perl OpenGL Release. I found that I also had to remove the line glEnable(GL_LIGHTING); from init, or the screen was black. By the way, if you havn't seen it, there is a very nice example in the SVN rev called, that is where I found those function's need for arrays. looks like it displays DNA type shapes, maybe you will find it contains some useful ideas.

      P.S. I'm running the NVidia driver on linux.
