Build order

llvm-minimal-git
spirv-headers-git
spirv-llvm-translator-minimal-git
libclc-minimal-git
mesa-minimal-git

N.B. these packages are closely tied together, make sure you build all of them in a short period of time (worst case on my system is around 3 hours) .

Build frequency

I aim to build everything (including the lib32 part) atleast once a week.

How often you build this is a personal choice, but once a month is in my opinion the absolute minimum .

In that timeframe mesa will have seen almost 1k commits, llvm/clang gets more.

Why does this package hard depend on llvm-minimal-git ?

  • performance

archlinux repo packages are build with -march=x86-64 -mtune=generic which works on lots of machines but makes limited use of modern processor capabilities. For many packages this has little impact, but with llvm my experience is different.

My local builds for llvm / mesa are done with -march=native and this has a noticeable effect on their performance.

How big the benefit of this is depends heavily on the exact hardware you use. Worse, the software setup also impacts this. The only way to find out if it benefits your system/software setup is to try it out yourself.

  • easier maintenance and troubleshooting

Since i started my first mesa trunk package late in 2010 I have maintained versions without any llvm, one llvm implementation, split versions, singular versions, versions supporting multiple llvm implementations , switch from libgl hacks libglvnd to allow mesa & nvidia to cooperate etc.

Depending on one llvm variant in a non-splitted singular version results in a simple PKGBUILD that is easy to maintain.

Troubleshooting is also much easier if maintainer uses the same llvm variant as users.

If people feel those reasons are not good enough to hard depend on llvm-minimal-git , maybe I should transfer ownership .

Why does this exist ?

Basically mesa/mesa-git build almost everything they can build.

This package tries to build just enough so everyone can use it, but disables older and/or unused components.

Check https://bbs.archlinux.org/viewtopic.php?id=261629 for a discussion about this package.

Thanks and confirmed.

Fixing was trickier then I hoped, but it works locally now.

Please try the latest (just uploaded) version.

Currently conflicts with opencl-rusticl-mesa-minimal-git

Lone_Wolf commented on 2024-09-06 21:17 (UTC)

no more manual changes to PKGBUILD needed

Lone_Wolf commented on 2024-09-05 16:53 (UTC)

An expanded version of the patch has been merged upstream with MR 309080 .

DRI3 was removed from meson options with MR 30952

Other then removing prepare() and the line with dri3 no other changes should be necessary. I tested with llvm-libs-minimal-git 20.0.0_r510230.1293ab35e406-1 .

dropped prepare to drop the patch, dropped dri3 (absolutely no idea why mason fails with dri3 if the patch isn't present), libclc, dropped all opencl parts in order to build. Guess llvm20-change-in-GetResourcesPath.patch needs updating.

Build successful after the revert to Arch repo's glslang/spirv.

Package no longer depends on spirv-tools-git & glslang-minimal-git.

If upgrading gives issues you should act as if you're building it the first time.

Lone_Wolf commented on 2024-08-09 23:39 (UTC)

The build failure was caused by this llvm commit: https://github.com/llvm/llvm-project/commit/ccb2b011e577e861254f61df9c59494e9e122b38

It was reverted with https://github.com/llvm/llvm-project/commit/a15de177728ec83f37bdd8f39d4a8f57e95c3d21 due to build failures

I did a full rebuild without issues.

Built today. Only tested DOOM Eternal and seems to be fine. Only did radeonsi/amd,swrast. Mesa-minimal-git compiled but had trouble moving opencl files to build the package. Removed all opencl related from the PKGBUILD. Built just fine afterwards.

build is broken：
