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.

That looks to have solved my issue, thank you very much :)

  • Patch updated to latest version, unfortunately llvm tests now fail due to upstream changes.

  • Cebtenzzre, upon checking I found other files missing.

I added options=('staticlibs ') .

Lone_Wolf commented on 2019-11-01 10:35 (UTC)

That specific fail is due to the enable-SSP-and-PIE-by-default patch . It comes from the extra/clang package and has given that error since the patch was added.

I'll check if it has been changed in extra llvm 9 package.

Unsure how to track this one down as the size of this build is way beyond me, any idea's what went on here? I am on Manjaro and just used pacman to do a standard update. This is the only update I am missing.

One library that is missing if staticlibs is not enabled is "/usr/lib/clang/10.0.0/lib/linux/libclang_rt.ubsan_standalone-x86_64.a". I needed that library in order to use -fsanitize=undefined with clang.

  • ConfuZzled

I never tested it, but doubt it is a good idea. building mesa-git is fast (typically 1-5 minutes on my system).

  • Cebtenzzre

/usr/lib/clang/10.0.0/lib/linux/ folder from llvm-git package holds compiler-rt runtime files. Could you provide a testcase to show what you're missing ?

Cebtenzzre commented on 2019-10-29 22:51 (UTC)

I needed to add options=('staticlibs') to the PKGBUILD to get the static libraries that are part of compiler-rt. The Arch repo package for compiler-rt sets this option.

ConfuZzled commented on 2019-10-11 11:55 (UTC)

Does this package contain everything that llvm-libs-minimal-git does? While the AUR package for mesa-git I can obviously configure to use llvm-libs-git, the package in PedroHLC's still depends on it, which causes a file conflict. Would there be any issues in making this also provide llvm-libs-minimal-git?

Sinistar commented on 2019-09-25 21:44 (UTC) (edited on 2019-09-25 21:54 (UTC) by Sinistar)

Yes I add the version to the dependency. I also split out the packages as they are in the extra repo, but do not build lld or lldb.
