Notes for macOS
================
Mesa builds on macOS without modifications. However, there are some details to
be aware of.
- Mesa has a number of build-time dependencies. Most dependencies, including
Meson itself, are available in `homebrew <https://brew.sh>`, which has a
Mesa package for reference. The exception seems to be Mako, a Python module
used for templating, which you can install as `pip3 install mako`.
- macOS's default C compiler doesn't play nice with some C11 idioms used in
Mesa. To workaround, set `-Dc_std=c11`.
- macOS is picky about its build-time environment. Type `brew sh` before
building to get the Homebrew dependencies in your path.
Mesa's default builds with the Apple GLX uses Mesa as a front for the
hardware-accelerated system OpenGL framework, to provide hardware acceleration
to X11 applications on macOS running via XQuartz.
Mesa's software rasterizers also work on macOS. To build, set the build options
`-Dosmesa=true -Dglx=gallium-xlib` and select an appropriate Gallium software
rasterizer.
For native hardware, stay tuned for updates here!
