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.

Seems like problem fixed in upstream, everything builds now.

Here is log, not very informative, but maybe helps
http://pastebin.com/raw.php?i=rQsTPvGg

I also searched for *.log files in building directory and found this
./aur-clang-svn/src/llvm-build/build/CMakeFiles/CMakeError.log
http://pastebin.com/raw.php?i=igGZaTdK

I have no idea where else cmake could hide details on this error, but will try to provide any helpful info

Also report the problem upstream.

Svenstaro commented on 2012-10-11 14:15

Please pastebin the error.

Can't build after latest gcc update, standard trick with chaging _gcc_ver=4.7.2 in PKGBUILD doesn't help, build fails on 18% with message:

The current gcc version has been updated to 4.7.1, preventing this package to build as it explictily requires gcc=4.7.0.
Changing the "gcc=_gcc_ver" to "gcc>=_gcc_ver" fixes the build.

I had the same problems with includes as reuben.bond, with his modifications everything works.

I modified the PKGBUILD for easier rebuilding without the need to compile everything again every time, in case someone is interested, here's the patch: https://github.com/mosra/archlinux/commit/76d6c4b99a2e22889c016c026a3c807f2c21a958

It's not yet clear whether the bug is in GCC or LLVM/Clang. LLVM guys think it's a GCC bug (they are closing all bug reports), while the lead GCC developer thinks it might be a strict aliasing bug in LLVM/Clang. I'm afraid it won't be resolved soon, so just include the workaround ;)

Svenstaro commented on 2012-04-23 01:20

Isn't this just a workaround? Since this is the svn package, we can easily fix it by showing upstream the wrong behavior. Did you open an upstream bug? If so, please link it here.

ducakar commented on 2012-04-23 01:03

Please add "-fno-tree-pre" to CFLAGS/CXXFLAGS because clang crashes when run with "-Wall".
