  • llvm

Why would I want to use llvm development versions ?

For full functionality and latest features mesa trunk master needs to be build against llvm trunk master.
If you build against stable llvm things MAY work, but you're likely to lack some features and face stability issues.

Mesa-git uses a custom environment variable MESA_WHICH_LLVM for flexibility.
It has 4 values.
1 : aur llvm-minimal-git
2 : aur llvm-git
3: llvm-git from LordHeavy' unofficial repo
4: llvm from extra repo

I use value 1 95% of the time and set this in ~/.bash_rc .
If MESA_WHICH_LLVM is unset or empty, the default value of 4 (extra llvm) is used.

AUR Helpers are NOT supported

I built and test with makepkg. Building with Devtools and Clean Chroot Manager should work fine also (I test them occasionally).

This package and lib32-mesa-git use a custom method to dynamically determine which llvm version is to be used. Several AUR helpers (atleast pamac and yay) have problems with that method.

Incase you try to build mesa-git with one of those AUR helpers


run makepkg --printsrcinfo > .SRCINFO after downloading and BEFORE building.

That should help pamac and yay to handle my custom method.

  • issues
Simple issues can be dealth with through aur comments, but sometimes discussion is needed.
Use for that.
  • main difference with stable repo package
[extra]mesa is a split package, but aur mesa-git isn't.
Basically with aur mesa-git you get everything in one package, while [extra]/mesa allows you to leave out some parts if you don't want/need them.
Having a single package reduces maintenance and makes switching from stable to mesa-git rather easy, though reverting back to stable can be tricky.
  • meson settings
Those who compare PKGBUILDs will notice I don't use arch-meson, but meson setup.
I disagree with some of the settings made by arch-meson (especially the buildtype and enabling LTO by default) and feel using meson setup is cleaner.
  • how to update

run pacman Syu update non-repo packages for llvm if you use them

build mesa-git, log out , restart X .

run glxinfo to verify basic OpenGL functionality

build lib32-mesa-git

run glxinfo32 to verify basic OpenGL functionality for multilib programs

I have the same issue as @yurikoles on latest Arch testing. mesa-git and libglvnd-gles2 (and also the same for libglvnd from repos) conflict because of 'egl.pc' and 'gl.pc'

yurikoles commented on 2019-09-28 15:55

Hi @Lone_Wolf,

Yes, and I think that most users of this package is also on testing.

Lone_Wolf commented on 2019-09-28 15:53

Are you using libglvnd 1.2.0-1 from testing repo ?

yurikoles commented on 2019-09-28 15:36

error: failed to commit transaction (conflicting files)
mesa-git: /usr/lib/pkgconfig/gl.pc exists in filesystem (owned by libglvnd)

same for lib32

Are you trying to build a custom version of community/mpv or a specific aur package for mpv ?

What is the error you get ?

artivision commented on 2019-09-23 12:24

Good day, cannot build MPV with Mesa-Git on my system.

Lone_Wolf commented on 2019-09-02 13:02

Thanks for the patch, Sinistar.

I had found the bug and reported it . I'll add the patch to that BR.

Unfortunately there have been other changes in clang that make clover build fail, so i've disabled opencl support for now. build failure log at

Sinistar commented on 2019-09-01 15:41

Sometime after 8/8 a clang 10 update broke clover, patch below for those using the latest version of LLVM.

@NilsBrause It needs to be provided by libglvnd. I made an AUR package to solve this problem until nvidia merges the related MR here:

NilsBrause commented on 2019-07-25 15:15

Compared to stock mesa, this is missing "egl.pc" for use with pkg-config. Could you add this, please?
