Hello folks,

I have a problem with creating a glcanvas in xforms. I'm using xforms 0.88 and
MesaGL 2.6, and using CC compiler on SunOS 5.5.1. To add a glcanvas, I used
fl_add_glcanvas , and it was perfectly working on demo files such as gl and
glwin, but mine was not working. It showed me the following message.

GLCanvas: OpenGL not supported
In CanvasInit [canvas.c 248] Unable to initialize canvas

On the other hand, I tried fl_add_mesacanvas in forms.h, but since that
function was not contained in libforms.a, I couldn't link with it. Is this
function already deleted from the library ? And generally in what kind of
situation does this kind of problem(can't create glcanvas) happen ? CC
compiler can cause this problem ?

Sorry for my cluelessness.
