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.

I decided to run ninja clang-check to see if it reported something useful and it did.

FAILED: tools/clang/test/CMakeFiles/check-clang

Comparing include files between this package, my llvm-lw-* variant and repo llvm shows this package is indeed missing some.

example : extra/compiler-rt & compiler-rt-lw-git both have usr/include/sanitizer/ & /usr/include/xray folders. llvm-git has those folders under usr/lib/clang/9.0.0/include .

It looks like compiler-rt and/or clang are not build correctly. This needs to be investigated further.

I'll see if this allows Clang to run properly.

@Lone_Wolf

some packages still depend on clang-svn/llvm-svn, for example libclc-git

PedroHLC commented on 2019-04-13 20:58 (UTC) (edited on 2019-04-13 21:00 (UTC) by PedroHLC)

Just in case someone needs, building with a systemd-nspawn container requires some capabilities, or disable tests.

Lone_Wolf commented on 2019-04-13 15:23 (UTC)

Well, I haven't found the cause of clang breakage, but did find a workaround :

Use llvm-lw-git + compiler-rt-lw-git + clang-lw-git .

QuartzDragon commented on 2019-04-13 13:36 (UTC)

Don't bother.

I got the same error even without the patch, before your latest commit.

Lone_Wolf commented on 2019-04-13 13:31 (UTC)

QuartzDragon : building in clean chroot gives same error.

I'll try building without the enable-SSP-and-PIE-by-default.patch .

Lone_Wolf commented on 2019-04-13 10:32 (UTC)

  • bpierre, was python2 installed during build ? If so, try removing python2 (temporarily) or build in a clean chroot.

  • QuartzDragon, I get the same error. I'll check if building in a clean chroot makes a difference.

  • I thought llvm-libs-git would no longer conflict with llvm-libs, but it still does. Will check how lordheavy llvm-svn does it.
