Right, I think the only way for it to have failed there is for
make_current_gl_handler() to have failed. And I've not known that to fail
(except silently, i.e. it fails but says it has not failed, in which case
GL crashes). So this is a puzzle. Now in make_current_gl_handler() there
are the lines:
if (!ok || !(glGetError() == GL_NO_ERROR))
return CCPN_FALSE;
you could change that to:
if (!ok) /* removed glGetError() */
{
printf("make_current_gl_handler failed: %d\n", glGetError());
return CCPN_FALSE;
}
and see if it works (re-compile as usual in ccpnmr1.0/c). If that fails
(and it probably will) then we are probably stuffed. But it would be
interesting to know what the error code is. (I'll have to try and find
where that information is stored, what they mean.)
