Phoronix: Waffle 1.1 Gets EGL + GBM, Android Toppings

Chad Versace of Intel released Waffle 1.1.0 on Monday, which is a cross-platform library for deferring selection of the OpenGL API and windowing system until run-time. Waffle makes it easy to switch between X11 with GLX or EGL, Wayland with OpenGL ES 2.0, and other windowing / GL API options...

Wayland 0.99 has also been released.

Final release on October 22nd.

Waffle is a great idea. It's purpose is to replace stuff like GLX/WGL/CGL and the initialization parts of GLUT, right?

From what I understand, it's an abstraction layer that lets you write code which can easily run on GLX, WGL, CGL, EGL, etc without having to write code specific to one of those types. If it takes off, it should ease cross-platform porting + compatibility.

Exactly. The first project to seriously use Waffle is Piglit, where it replacs GLUT as the platform abstraction layer. GLUT had some significant shortcomings, such as no support for GL core contexts and no support for Wayland, which Waffle now solves. Some people have also expressed a desire for Cairo to use it once it gains a few more features.

In the future, I and some other Intel devs hope for Waffle to replace GLEW too. If those plans come to fruition, then its extension resolution will also support the OpenGL ES APIs.
