FYI, those using the Allegro egg already gain access to most/all gl extensions:
http://wiki.call-cc.org/eggref/4/allegro/gl Also, this portion of the Allegro egg was forked out as the glext egg, though it's poorly documented: http://wiki.call-cc.org/eggref/4/glext https://github.com/dleslie/glext -Dan On Mon, Apr 14, 2014 at 5:08 AM, Mario Domenech Goulart < mario.goul...@gmail.com> wrote: > Hi Alex, > > On Sun, 13 Apr 2014 16:12:08 -0400 Alex Charlton < > alex.n.charl...@gmail.com> wrote: > > > opengl-glew provides bindings to OpenGL’s core profile while handling > extension loading with GLEW: > > > > https://github.com/AlexCharlton/chicken-opengl-glew > > > > There are two existing eggs that have some degree of overlap with this > > one.
