waffle has four "backends", each having their own dependencies. At least one "backend" must be enabled, otherwise Waffle will refuse to build. The "backends" are: - glx, which needs full OpenGL + x11-xcb - wayland, which needs wayland-client, wayland-egl and EGL - x11-egl, which needs x11-xcb and EGL - gbm, which needs gbm, libudev and EGL Backport an upstream patch fixing a build issue with musl toolchains. Add a new patch fixing build with Wayand without X11.

Waffle is a cross-platform library that allows one to defer
|
|
selection of an OpenGL API and of window system until
|
|
runtime. For example, on Linux, Waffle enables an application
|
|
to select X11/EGL with an OpenGL 3.3 core profile, Wayland
|
|
with OpenGL ES2, and other window system / API combinations.
|
|
|
|
Waffle's immediate goal is to enable Piglit [1] to test
|
|
multiple OpenGL flavors in a cross-platform way, and to allow
|
|
each Piglit test to choose its OpenGL API and window system
|
|
at runtime. A future goal is to enable the ability to record
|
|
(with another tool such APITrace [2]) an application's OpenGL
|
|
calls on one operating system or window system, and then
|
|
replay that trace on a different system.
