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.

Ive tried to get this to work a few different ways now, but it always fails on either the ocaml_doc build or one of the checks. This combined with the rather long compile time has me flustered

LLVM_POLLY_LINK_INTO_TOOLS should be ON not OFF for polly support now.

Lone_Wolf commented on 2020-06-26 15:17

Just build and got no polly related erorrs, only clang related test failures.

Please try again and post full logs somewhere if you still have the error .

Any idea how to solve this?

EDIT: NVM, I switched to an earlier commit and the error is gone.

Thx Sinistar.

I was looking into adding python-psutil as checkdepend and had noticed time spend in check() had increased a lot but not figured out the reason yet.

Sinistar commented on 2020-06-07 19:15

Just an FYI. In the check section "check" by itself now compiles and run all test, and seems to need two dependencies "rsync" and "python-psutil". If you just want to run LLVM check use check-llvm.

@Lone_Wolf: Thanks for giving it a try!

Building flang with MLIR fails, disabling FIR/MLIR for flang also breaks build.

I've filed , but for the time being adding flang is not possible.

Lone_Wolf commented on 2020-04-14 22:02

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? (
