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.

A quick peek indicates flang requires mlir, so I'll have to add both projects. Will look into it.

jschwab commented on 2020-04-14 20:24

Could flang be added now that it has been merged? (

Lone_Wolf commented on 2020-03-19 23:10

build failure worked around by building tests in check() instead of build() function

itsshash , this package is intended to be build in a clean chroot.

If you want to build on a live system using makepkg (or an aur helper) , make sure to run pacman -Syu and remove any older versions of this package before starting.

ATM that won't help though, as there's a build failure.

❯ yay -Sa llvm-ocaml-git ==> Error: Could not find all required packages: ocaml=4.09.0 (Wanted by: llvm-ocaml-git)

ocaml has been updated to 4.09.1-1, so unable to build as AUR package requires ocaml=4.09.0

  • LH repo is build against official [testing] , [community-testing] and [multilib-testing] repos. His packages typically use the same structure as repo versions. Using the packages from his repo without enabling testing repos can cause weird issues.

  • chaotic-AUR repo builds packages against core/extra/community repos . He does build aur mesa-git against aur llvm-minimal-git package like I do and also builds this package.

  • This package is the only one that tries to provide a llvm trunk development suite that doesn't depend on any stable llvm parts. Its svn predecessor (maintained by kerberos who also provided binary versions) ) was the only choice for aur mesa-git. When the package switched to git , I got stuck with maintaining it. Soon I'll try to find someone else.

  • for those wanting llvm trunk solely for mesa-git, llvm-minimal-git is a better choice then llvm-git .

Is there any difference between this package, lordheavy's llvm-git/mesa-git, and chaotic-aur's llvm-git/mesa-git?

gardotd426 commented on 2020-03-06 22:08

@Lone_Wolf that's what I figured, I went ahead and added it. I've used it before on Manjaro but didn't know if there was a key out there or if I was supposed to do it like that how I did before. I'm installing everything now, thanks

Lone_Wolf commented on 2020-03-06 21:52

LH repo is unsigned, so there are no keys.

Setting TrustAll for his repo is the only way to use it.

gardotd426 commented on 2020-03-06 21:28

@Lone_Wolf what're the keys for that repo? Usually you can find the pacman-key recv-keys key numbers for unofficial repos like chaotic and valveaur but I can't find anything for mesa-git. I guess I could put a trustall in the pacman.conf but I'd like to not have to.
