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

@lesto autoconf is a requirement to build from AUR, it is in the base-devel package... @anadon its built from an SVN repo... or do i misunderstand what your trying to say @kode54 I have yet to try out your patch, but are you able to elaborate on what/why you have included ipo in the linker? (just curious if this will fix my issue) Finally, i figured i would answer/ask while i try to desperately to get radeonsi working :)

lesto commented on 2013-05-22 23:30 (UTC)

missing autopconf from dependencies.

anadon commented on 2013-05-22 16:13 (UTC)

Hello, Incorrect listed dependancies for llvm, and no official or aur package for llvm above 3.2.

kode54 commented on 2013-05-21 01:05 (UTC)

Here's a modified PKGBUILD to support adding custom patches to the tree. https://gist.github.com/kode54/5616844 I've also uploaded a single patch which is needed to use the current mesa-git against the current llvm-amdgpu-svn, which is LLVM version 3.4. https://gist.github.com/kode54/5616841

Hey just to post an update, i was un-able to get radeonsi support going with llvm-amdgpu-svn and according to the guy who is building the gallium drivers (my error message) has only just submitted some patches that compile properly, and it should be in there this time next month. So if anyone else has luck let me know otherwise, will have to checkout the svn next month. Thanks!

turtil commented on 2013-05-19 22:24 (UTC)

@klausenbusk Yeah I have done, i also tried snapshot and the normal llvm for kicks, however a couple of people on IRC managed to get it up and running for the R600 only, couple of them also mentioned that radeonsi is a little broken. Im going to attempt to make some changes today and see if i can grab the latest svn and get this to work. The only notable difference is that im on linux-mainline which is 3.10rc1 in an effort to get Video Acceleration working, which a couple of them did!! Keep up the good work, and if you have any other ideas let me know Thanks!

<deleted-account> commented on 2013-05-19 17:47 (UTC)

turtil, try llvm-amdgpu-svn

<deleted-account> commented on 2013-05-19 15:57 (UTC)

kode54, bison and flex is member of base-devel and should therefor not be included in makedepends. turtil, i will take a look..
