We should really try to upgrade to a newer version. A problem is that we've made some local modifications. But that really shouldn't be a big problem, I hope. Anyway, I made a mistake. After I installed libxext-dev it turns out fltk-1.0.11 really does find OpenGL and HAVE_GL is set to 1! Thanks anyway! _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
