When you have this package installed applications that are built against repo-llvm/clang WILL fail unless they are rebuild against this package.

This includes QTCreator, kdevelop , mesa, intel-compute-runtime, gnome-builder to name a few.

Archlinux currently has 3 llvm git implementations

  1. This package

    • It aims to provide a full llvm/clang compiler environment for development purposes.
    • Supports cross-compiling , bindings for external stuff (python, ocaml etc) , and some things not in extra-llvm.
    • intended to be used with archlinux core,extra & community repos
    • CONFLICTS with extra llvm/clang packages
    • Currently there's no repo with binary versions
  2. llvm-minimal-git

    • focuses on providing stuff needed for AUR mesa-git. Doesn't support cross-compiling or any bindings for external stuff like ocaml & python.
    • intended to be used with archlinux core,extra & community repos
    • compatible with extra llvm/clang packages
    • no repo with binary versions
  3. packages created & maintained by Lordheavy, an arch developer

    • intended to be used with archlinux testing repos
    • sometimes has problems on systems where testing repos are disabled
    • uses same package structure as llvm/clang in official repos
    • source
    • binary versions in LordHeavys unoffical repo

I've looked good at clang-trunk , llvm-svn, repo llvm/clang packages and think this package is now on route to become a worthy successor to llvm-svn .

  • llvm-libs-git holds the runtime libraries.

    It conflicts with the repo llvm-libs package. This is the only way to make sure the llvm linker from git is used, and that's needed for a full dev environment.

  • llvm-git

    has llvm , clang, compiler-rt, ocaml & python bindings, polly , lld , lldb .

The Package now uses a new environment variable to make ninja behave, NINJAFLAGS. If you want to use it adjust the snippet below to your desired values and add it to makepkg.conf.

Incase you are satisfied with ninja defaults you don't need to do anything.

# Add to makepkg.conf
# limit ninja to 20 jobs
# requires special code in PKGBUILD
# see ninja --help for additonal options

The check() function fails rather often, but I do suggest to build with them. If build fails due to test failure you can add --nocheck to skip the tests.

Unless you have something like a terabyte of RAM, this package can only be built with the --nocheck option.

@Lone_Wolf, @onelumin,

Fixed. Thanks,

The package is broken as of last week. Commit 2980029 removed /llvm/bindings/python.


cp -a llvm/bindings/python/llvm  "$pkgdir"/usr/lib/python$_py/site-packages/

line must be removed.

Please add


to the cmake command as rusticl needs llvm build with that option .

Thanks. Do we need bindings here? I see it's turned off in the [Extra] and your llvm-minimal. If not, I'll turn it off.

Edit: Never mind the above. I'll be updating the version number as there are no Python binding providers for llvm-git.

Lone_Wolf commented on 2023-05-05 09:26 (UTC)

It's in package_llvm-git()

    cd llvm-project
    # Install Python bindings and optimize them
    cp -a llvm/bindings/python/llvm  "$pkgdir"/usr/lib/python$_py/site-packages/
    cp -a clang/bindings/python/clang  "$pkgdir"/usr/lib/python$_py/site-packages/
    _python_optimize "$pkgdir"/usr/lib/python$_py/site-packages

Can you point out where in the PKGBUILD python version is hard-coded? Thanks,

AtticFinder65536 commented on 2023-05-04 15:50 (UTC)

python 3.10 reference is hardcoded in PKGBUILD, it needs to be updated to 3.11 now

New package:

llvm-opt-git can be installed alongside llvm-git/llvm. It installs to /opt. It builds with make rather than ninja.

The diff is quite long:
