Mesa and llvm are closely tied together. Everytime the llvm mesa is built against changes/updates , mesa needs to be rebuilt.

I expect anyone building mesa-git against one of the llvm trunk variants to be able to do that themselves, but atleast some of the people that built against repo llvm don't understand how to deal with such a rebuild.

The rest of this post is meant for those people.

  • Verify if latest PKGBUILD requirements match llvm repo versions.
  • If they don't , post to alert me of this.
  • DELAY the update of llvm/clang suite and their lib32- counterparts
  • Once the PKGBUILD does match, download it.

Option A - best one

  • run pacman -Syu to ensure your system is in sync with your mirrror server
  • build mesa-git in a clean chroot

see for the official way or for an alternative method.

  • install the newly built mesa-git
  • run pacman -Syu
  • ready

Option B - 2nd best

  • revert to repo mesa
  • pacman -Syu
  • build mesa-git
  • switch from mesa to mesa-git
  • ready

  • choosing which llvm variant to build against

WARNING : aur helpers don't support this method at all. They check .SRCINFO and that is set to build against repo llvm when it is uploaded.

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.

  • 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

Crocus gallium driver added to the PKGBUILD.

kprkpr commented on 2021-06-20 12:09

Hi! In newer mesa drivers, there is a new gallium driver, crocus You can enable at PKGBUILD? I tried and works good Thanks :)

" -D gallium-drivers=r300,r600,radeonsi,nouveau,svga,swrast,virgl,iris,zink,crocus \"

How embarrassing. Yes, I did that some time ago but was not at my pc for some weeks and totally forgot about that. Shame on me, my deepest apologies. Should have checked the first lines of my own logfile :-(

Thank you for your time and sorry for wasting it.

C compiler for the host machine: clang (clang 12.0.0 "clang version 12.0.0")
C linker for the host machine: clang ld.bfd 2.36.1
C++ compiler for the host machine: clang++ (clang 12.0.0 "clang version 12.0.0")
C++ linker for the host machine: clang++ ld.bfd 2.36.1

On archlinux default complier is cc / c++ currently gcc 11.10 .

I just tested in a clean chroot with gcc and there is no error for that target reported .

Has manjaro switched default compiler to clang or did you make that change yourself ?

Hi, thanks for your help. My system is still on pacman 5.2 (manjaro stable). I use makepkg for building.

Here is the log from the build:

Lone_Wolf commented on 2021-06-15 21:16

-lLLVM-12 suggests you're building against stable llvm and in that case you should not need any other *-git dep (except maybe for libdrm) .

Is your system / manjaro still on pacman 5.2 or now on pacman 6.0 ?

Are you using makepkg, clean chroot build or some helper ? If the latter verify if the error occurs with supported build methods like the first 2.

If you are using supported build methods, add --log to your build command . upload the logs somewhere publicly availale and post the link.

Hi, I'm on manjaro and the gcc (10 -> 11) and llvm (11 -> 12) got recently updated. I think I rebuilt every *-git dependency for mesa-git, but I still get an error from the linker about not recognized file format:

Has anyone faced the same problem or has any idea what to do?

@JoshuaAshton, Thanks for the report. PKGBUILD updated accordingly.

JoshuaAshton commented on 2021-06-06 22:24

llvm stuff needs updating

rjahanbakhshi commented on 2021-05-10 19:04

The default branch is now main instead of master in the upstream. PKGBUILD updated to point to the main.
