  • 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

Switched to llvm-lw-git and associated packages for llvm trunk master.

Instructions to use other llvm trunk versions will be posted soon.

Faalagorn commented on 2019-04-17 09:17

Nothing major, but I think you should also update lib32-mesa-git with latest PKGBUILD changes :)?

Lone_Wolf commented on 2019-04-12 20:46

Mesa-git now uses aur llvm-git exclusively.

If you wish to use an alternative llvm development implementation, edit the PKGBUILD.

Lone_Wolf commented on 2019-04-09 14:34

All 3 should provide the needed llvm / clang svn.

Lone_Wolf commented on 2019-04-07 16:34

Currently there are 3 possibilities for an llvm trunk version

Aur llvm-lw-git (multiple packages, tailored to my workflow)

Aur llvm-git

LordHeavy unofficial mesa-git repo

Thanks for the alert, both mpv & vlc have glslang as (indirect) dependency, so it's present on many systems.

Will add it this weekend.

PedroHLC commented on 2019-04-03 13:42

Program glslangValidator found: NO

src/vulkan/overlay-layer/ ERROR:  Program(s) ['glslangValidator'] not found or not executable

A full log can be found at /home/main-builder/pkgwork/src/_build/meson-logs/meson-log.txt

Should glslang be added as dependency? EDIT: Yep, adding it solved.

Lone_Wolf commented on 2019-03-27 16:28

vulkan overlay support added, thanks for the reminder.

Haxk20 commented on 2019-03-26 18:07

Lone_Wolf can you please add -D vulkan-overlay-layer=true as a build option ? I use vulkan for gaming a lot and having that overlay helps a lot. Thank you

kmk3 :

The missing pkgconfig-files have no relation with mesa-libgl ( see if you want to know more)

Maintainers/users that want to replace mesa-libgl as dependency should look at what their package needs. If they just want to be sure there's OpenGL support, depend on libgl .

VanLaser: Good to know that, it may be different soon though.

Another alternative is the llvm-svn packages from lordheavy's binary mesa-git repo.
