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.

==> Starting build()...
-- clang project is enabled
-- clang-tools-extra project is enabled

Normally the first few lines after starting build deal with detectibng which compiler is used 

-- The C compiler identification is GNU 11.1.0
-- The CXX compiler identification is GNU 11.1.0
-- The ASM compiler identification is GNU

Also :: Downloading the latest sources for devel packages llvm-git, llvm-libs-git, llvm-ocaml-git... indicates you are using some aur helper.

That suggest some potential causes :

  • your aur helper

  • cmake using stale cached date

  • something in your makepkg.conf

Try building with makepkg --syncdeps --rmdeps . If that gives simlar results , try makepkg --cleanbuild --syncdeps --rmdeps .

@rjahanbakhshi unfortunately not, it is probably a thing on my side I just tried it

rjahanbakhshi commented on 2021-10-22 08:44 (UTC)

@weltio @Lone_Wolf

I just built it in an updated clean chroot and it was successful. Perhaps an upstream update? Can you double-check if the error still exists?

Those are the first lines of the build process, but there is no mention of lua besides "-- Enable Lua scripting support in LLDB: TRUE"

Lone_Wolf commented on 2021-10-21 22:10 (UTC)

lua_newuserdata appears to be replaced in lu 5.4, and lldb requires lua 5.3 . Looks like the dependency needs to be changed to lua53.

In your build log there should be lines similar to

-- Found SWIG: /usr/bin/swig (found suitable version "4.0.2", minimum required is "3.0")  
-- Found Lua: /usr/lib/liblua5.3.so;/usr/lib/libm.so (found suitable exact version "5.3.6") 
-- Found LuaAndSwig: /usr/lib/liblua5.3.so;/usr/lib/libm.so  
-- Enable Lua scripting support in LLDB: TRUE

Post those lines from your system.

Probably due to:

lua 5.4.3-1
lua51 5.1.5-9
lua52 5.2.4-5
lua53 5.3.6-1

right? Is there a solution for that?

Sinistar commented on 2021-10-20 00:27 (UTC)

just a heads up. libffi has been updated, so user will need to rebuild LLVM.

Lone_Wolf commented on 2021-08-23 10:08 (UTC)

Glad you found the solution , for those wanting more info :

weltio commented on 2021-08-22 22:42 (UTC) (edited on 2021-08-23 07:11 (UTC) by weltio)

I built the package with -D CMAKE_BUILD_TYPE=Debug and 

readelf --debug-dump=decodedline llvm-git/src/_build/lib/libclang.so.14.0.0

actually shows debugging content but:

readelf --debug-dump=decodedline /usr/lib/libclang.so.14.0.0

does not - is the file not installed correctly or what happens? isnt it expected to be there with debugging symbols?

Sorry for being stupid:

-options=('staticlibs')
+options=('staticlibs' 'debug' '!strip')

Lone_Wolf commented on 2021-08-16 14:44 (UTC)

Those are used by aur mesa-git to differentiate between this package and the one from lordheavy unofficial repo that also has a llvm-git package .
