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
NINJAFLAGS="-j20"

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.

@Lone_Wolf This is embarrassing, but I've never really gone to this extent to get something in the AUR installed so I don't know what you mean by "log files". Reading through man makepkg I'm guessing you mean for me to use the -L switch like, LOGDEST=$PWD/logs makepkg -sirL? This?

lldb tests re-enabled.

While looking at lldb cmakelists.txt for options to solve the test failure, I noticed an option to use system-provided python-six . Using that option allowed to remove a workaround from the package_llvm-git() function.

nstgc : post log files of the build somewhere. I'll run a clean chroot build to verify dependencies.

I happen to agree with YuriKoles. If we, the end user, decide to ignore warnings we can, but they are there for a reason, even if it's a bad reason. I appreciate the effort, particularly identifying a missing dep, but it seems just having us add --nocheck is the better solution. I admit I'm not sure how this would be done (I've never made anything with the ABS), but perhaps on a failed check print a message about this being "normal" and that --nocheck is "safe"?

Also, it still still to be failing without --nocheck. I pulled the changes, and tried to clean build the package without --nocheck and I'm getting the same failures as before.

Hi @Lone_Wolf,

I'm sorry, but I think that selectively disabling tests makes no sense, if LLDB test fail it should be reported upstream instead of just pretending that there are no errors.

Lone_Wolf commented on 2020-03-03 18:16

check() function needed python module psutil, added that as checkdepend. This took care of 2+ unexpected failures, all remaing failures were in lldb-tests .

The lldb tests have shown the same failures for sometime now, and I haven't been able to figure out what causes them. I've disabled them, so for now the package should build without check() failures.

Failures during check() are unfortunately rather common for this package, check bottom lines of the pinned comment.

I'm having trouble compiling this. I'm not using an AUR helper and my Arch (not Manjaro) install is up-to-date.

Failing Tests (4):
LLVM :: tools/opt-viewer/basic.test
LLVM :: tools/opt-viewer/filter.test
LLVM :: tools/opt-viewer/suppress.test
LLVM :: tools/opt-viewer/unicode-function-name.test

Lots of failures in check() function (check-clang-tools) , but none in build() function.

Try adding ---cleanbuild to the makepkg command (or remove $srcdir yourself before building).

Confirmed and corrected. There were also other corrections needed because of python 3.8.
