To those with the directx errors : archlinux directx-headers pacakgae is 2 releases behind upstream. Try building against aur directx-headers-git .

I don't remember what d3d12 does, but offical mesa also supports it.

@ZephyrCheez : thanks, that option lead to meson subprojects and mesa sourcetree does appear to include the data needed to use them. Adding nouveau vulkan looks doable now, no idea when there will be time to implement it.

@Beiruty, those have the same cause as the other recent build failures : changes in intel drivers.

The build issues caused by changes in intel drivers are now solved for MESA_WHICH_LLVM 1, 3 and 4 (llvm-minimal-git , llvm from lordheavy unofficial repo and offical repo llvm )

MESA_WHICH_LLVM 2 (aur llvm-git) build is still broken, but I MAY have a solution for that without having to create new packages.

The good news is that once all 4 variants built again, only minor changes should be needed to add opencl clover & opencl rusticl support.

(A lot of the work required to built the intel drivers is also useful for clover & rusticl)

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

Normally i'd try to keep packages as vanilla as possible, but without this patch the package is unusable. The patch changes only 1 file and works fine on my system. The only downside seems to be libllvmradeon9.2.so is now bigger. Patch mentioned in bug 62434 added.

With builds from http://cgit.freedesktop.org/mesa/mesa/commit/?id=f70c3853513637fa6ed38e75f73d472a9fa61213 and later : upon starting X, the r600 driver fails and X falls back to software rastering. See https://bugs.freedesktop.org/show_bug.cgi?id=62434

corrected provides/replaces

Lone_Wolf commented on 2013-03-09 13:30 (UTC)

The xmlpool bug has been solved upstream, so this package builds again. Note that we switched from lvm-amdgpu-git which was build from tstellar's llvm tree to llvm-amdgpu-svn that is build from llvm master trunk. Also i've added --enable-g3dvl to configure flags, this should improve gpu acceleration for playing videos.

Lone_Wolf commented on 2013-03-08 19:04 (UTC)

building against llvm with amdgpu from svn master gives another , not llvm related, error : In file included from dri_screen.c:33:0: ../../../../../src/mesa/drivers/dri/common/xmlpool.h:96:29: fatal error: xmlpool/options.h: No such file or directory See https://bugs.freedesktop.org/show_bug.cgi?id=59261

Lone_Wolf commented on 2013-03-08 17:27 (UTC)

the llvm-amdgpu-snapshot package gives the same build error, so i slikely still a snapshot of tom stellar's repo. I'm looking into building llvm from svn now.

Lone_Wolf commented on 2013-03-08 15:56 (UTC)

mesa-git uses a split package that is basically a git version of the mesa packages in extra. It also builds all drivers. My package is a single one that builds only r300, r600 and radeonsi drivers. It also adds "experimental" configure flags like # additonal flags not in official mesa # --enable-gallium-gbm \ # --enable-xvmc \ # --enable-xorg \ # --enable-r600-llvm-compiler \ # --with-llvm-shared-libs I'll look into the issue in the bugreport, but llvm-amdgpu-snapshot used to be a snapshot of tstellar's repo.

Build filed with the same error message as this bug report https://bugs.freedesktop.org/show_bug.cgi?id=61992 Can't we just use llvm-amdgpu-snapshot (in community repo) instead of llvm-amdgpu-git ?

sasy360 commented on 2013-03-07 21:51 (UTC)

Hi Lone_Wolf What are the differences between mesa-git and your package?
