removed obsolete options, build now works again.

building opencl clover is disabled for now, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/11863

Those that need opencl should use rusticl instead. Note that rusticl at runtime is disabled by default, see https://docs.mesa3d.org/envvars.html#rusticl-environment-variables for info about enabling it.

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 the maintainer 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 https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_clean_chroot for the official way or https://aur.archlinux.org/packages/clean-chroot-manager 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 doesn't include this variable so it will use the default which is hardcoded to build against repo 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.

  • 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 , update mesa-git and restart X .

run glxinfo -B to verify basic OpenGL functionality

build lib32-mesa-git

run glxinfo32 -B to verify basic OpenGL functionality for multilib programs

I guess that should be possible, though i'm not sure of the benefits.

Maybe glamor / modesetting improvements ?

adding 'mesa-libgl' to 'provides' allows me to compile and install package 'xorg-server' without having to install official packages 'mesa' and 'lib32-mesa'

libclc requires hardware specific files in /usr/lib/clc .

My card is a RX 580 of polaris 10 family.

The gfx1010 suggest you have an RX 5xxx / Navi videocard ? libclc doesn't support those and may never do that.

Unfortunately rocm also doesn't seem to support them, so amd proprietary driver from opencl-amd is your only choice for opencl.

I've never been able to use the opencl that builds with mesa-git in the applications I have. I've tried running GPU calculations with Folding@Home, and benchmarking hashcat and they both fail unless I use the amdgpu driver version in the opencl-amd package. The failure message I get is in the code block below. Have you seen similar results? clinfo reports the mesa version is OpenCL 1.1.


clBuildProgram(): CL_BUILD_PROGRAM_FAILURE

fatal error: cannot open file '/usr/lib/clc/gfx1010-amdgcn-mesa-mesa3d.bc': No such file or directory

* Device #1: Kernel /usr/share/hashcat/OpenCL/shared.cl build failed.

clinfo results in a very similar error.

mesa master fails to build against lastest llvm trunk

https://gitlab.freedesktop.org/mesa/mesa/-/issues/2826

Lone_Wolf commented on 2020-04-26 13:22 (UTC)

tb0n3, the --nocheck is not the cause of that error.

I see the same errors you get. I have just checked and latest mesa-git does build against older llvm-minimal-git (11.0.0_r352002.cd8e9e8fcd3-1 from apr 21) .

It does look like recently something changed in llvm that requires adjustments in mesa .

tb0n3 commented on 2020-04-26 02:09 (UTC) (edited on 2020-04-26 02:52 (UTC) by tb0n3)

Since the big LLVM update that broke a few things I've been unable to build mesa-git. It fails due to LLVMVectorTypeKind being undefined. As the llvm checks always fail I was running --nocheck. Is it possible there's something in there that I'm missing because of this? This occurs with both llvm-git and llvm-minimal-git.

Having tried with the regular llvm packages from the regular repositories it built fine.

I have a problem with package update. I get this command output:

error: failed to prepare transaction (could not satisfy dependencies) :: installing lib32-llvm-libs (10.0.0-1) breaks dependency 'lib32-llvm-libs=9.0.1' required by lib32-mesa-git :: installing llvm-libs (10.0.0-1) breaks dependency 'llvm-libs=9.0.1' required by mesa-git
