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.

Please, add in provides clang-opencl-headers-git for spirv-llvm-translator-git. Also, can you add to compiled projects openmp? There is only openmp package in official repo and no openmp-git version.

Hi,

The formerly existing separate pkgbase named clang-git has been deleted ([PRQ#58222]).

You can consider creating a split sub-package named clang-git inside the llvm-git PKGBUILD.

@sir_randomuser,

Thanks, PKGBUILD updated accordingly.

@asgard see my comment, this resolves the error

LLVM version has been moved to llvm-project/cmake/Modules/LLVMVersion.cmake upstream.

pkgver needs to be changed to work correctly.

New pkgver needs to be:

pkgver() {
    cd "$srcdir"/llvm-project/cmake/Modules

    # This will almost match the output of `llvm-config --version` when the
    # LLVM_APPEND_VC_REV cmake flag is turned on. The only difference is
    # dash being replaced with underscore because of Pacman requirements.
    local _pkgver=$(awk -F 'MAJOR |MINOR |PATCH |)' \
            'BEGIN { ORS="." ; i=0 } \
             /set\(LLVM_VERSION_/ { print $2 ; i++ ; if (i==2) ORS="" } \
             END { print "\n" }' \
             LLVMVersion.cmake)_r$(git rev-list --count HEAD).$(git rev-parse --short HEAD)
    echo "$_pkgver"
}

Shouldn't extra/python-pexpect be marked as a dependency?

-- Could NOT find Python module 'pexpect'
CMake Error at /home/user/.cache/yay/llvm-git/src/llvm-project/lldb/test/CMakeLists.txt:43 (message):
  Python module 'pexpect' not found.  Please install it via pip or via your
  operating system's package manager.  For a temporary workaround, use a
  version from the LLDB tree with `LLDB_TEST_USE_VENDOR_PACKAGES=ON`

@mdupont,

Can you try to build it in a clean chroot and install the built package using pacman -U? Both convenience and classic ways should work.
