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
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.

Understood, you have thought about this and how you want to use it.

Atleast mesa trunk has used this method years ago, but stopped doing it because no other packages made use of it . I have no objections to adding $pkgver-$pkgrel values in llvm-git .

Keep in mind llvm-git follows upstream default branch, so will switch from 16 to 17 when upstream branches off stable 16 .

You may want to use something like 'llvm>=16' 'llvm<17' to ensure users can switch to stable 16 once it arrives.

alerque commented on 2022-11-29 06:03 (UTC)

@Lone_Wolf I understand what you are saying about so names and versions and agree it would be nice if this package added provides for the sonames with version data so other packages could add that as a run time dependency with proper heads-up when a rebuild was needed. However I think you're wrong about my suggestion being a failure: there is no harm in adding the package version information to the provides like like I showed. It does not solve the same problem as providing the soname, but it does solve a different problem. It allows this package to be used as a makedepends with version information for packages that require to be built against a minimum version newer than what is in [community] at this point. It won't provide a run-time way to keep the soname version matched, but it does provide a build time dependency that is flexible enough to be supplied by this or another future update to the stable package(s).

Lone_Wolf commented on 2022-11-28 12:01 (UTC)

alerque, doing it that way will fail at runtime as packages aren't linked to external libraries using package versions but through sonames .

the command find-libprovides from devtools package can help to make those visible.

$ find-libprovides --ignore-internal llvm-git-16.0.0_r443217.0b74cb42312b-1-x86_64.pkg.tar.zst 
libclang.so=16-64
libclang-cpp.so=16-64
liblldb.so=16-64
liblldbIntelFeatures.so=16-64
$ find-libprovides --ignore-internal llvm-libs-git-16.0.0_r443217.0b74cb42312b-1-x86_64.pkg.tar.zst 
libLTO.so=16-64
libRemarks.so=16-64
$ find-libprovides --ignore-internal llvm-ocaml-git-16.0.0_r443217.0b74cb42312b-1-x86_64.pkg.tar.zst 
bsdtar: *.so*: Not found in archive
bsdtar: Error exit delayed from previous errors.
$

If you run the same command on other archlinux (binary) llvm pacakges, you'll get similar results.

If this package adds those sonames to provides, applications can depend on an exact version of the shared library, get a warning when sonames change and a rebuild is necessary.

This package provides llvm but it does not do so in a way that includes the version information. Hence it is not currently possible for other packages to use it as a build time dependency with a version requirement that would let them start using the stable version when a sufficient version is released and packaged in [community] like makedepends=('llvm>=16'). This is negatively effecting builds like brave where we're unable to specify the dependencies correctly.

Here is a patch that should fix it which should apply cleanly with git am < file.patch:

atticf commented on 2022-09-13 02:20 (UTC)

Hi, I needed to install python-setuptools to clear this section. (I am using a clean chroot with only base-devel installed.)

    # Include lit for running lit-based tests in other projects
    pushd llvm-project/llvm/utils/lit
    python setup.py install --root="$pkgdir" -O1
    popd

Therefore I think it needs to be a make dependency instead of an optional dependency, because it's required to clear the package_llvm-git function by default. Unless the user is expected to intervene here, in which case I apologise for disruption.

rjahanbakhshi commented on 2022-08-14 10:16 (UTC)

@sir_randomuser,

Thanks for the update. Indeed ocaml-stdlib-shims is required to build this package in a clean chroot env. I updated the PKGBUILD and added ocaml-stdlib-shims.

sir_randomuser commented on 2022-08-12 17:43 (UTC) (edited on 2022-08-12 17:53 (UTC) by sir_randomuser)

EDIT: resolved by adding ocaml-stdlib-shims to makedepends

Hi, has anyone else been unable to build LLVM past couple of days?

For me it always fails here - regardless if I build it with GCC or CLANG:

This package follows the upstream llvm project and builds the very latest commit available from upstream default branch (main). It adjusts the version number dynamically on every build .

It's been building v15 since llvm 14 got its own branch as release/llvm14 early in february .

That archlinux repos still haven't switched to the latest stable release 14 doesn't matter for this (and other llvm trunk packages ).

Besides, a package that builds any fixed branch must reflect that in the name. For llvm14 that would be llvm14-git.

Feel free to start such a NEW package.

sysgen commented on 2022-07-02 04:03 (UTC)

As of today this will no longer install LLVM-14, but instead LLVM-15. More specifically : llvm-git 15.0.0_r428699.ccf7dd5e813d-1

Please consider pinning to the branch for LLVM-14, or to a commit number, untill LLVM-14 is in the extras repo. In any case, the version number should be amended.
