Pretty close. I lied, apparently the pthreads fix is in 0.44 https://github.com/mesonbuild/meson/commit/fc547ad05e5a8e650ae5bc2ecc7d40e4dbcc9f0f Here's my branch, but it needs rebase pretty bad, there's also a patch to use shared glapi that I added trying to see if that would get the build working that needs to be removed: https://github.com/dcbaker/mesa/tree/wip/meson-haiku Dylan
