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.

Lots of failures in check() function (check-clang-tools) , but none in build() function.

Try adding ---cleanbuild to the makepkg command (or remove $srcdir yourself before building).

Cannot build, get this c++: error: git: No such file or directory c++: error: working: No such file or directory c++: error: on: No such file or directory c++: error: it/llvm-git/src/_build/./lib: No such file or directory [278/7794] Building CXX object lib/MC/MCParser/CMakeFiles/LLVMMCParser.dir/AsmParser.cpp.o ninja: build stopped: subcommand failed. ==> ERROR: A failure occurred in build(). Aborting...

Confirmed and corrected. There were also other corrections needed because of python 3.8.

llvm-ocaml-git needs to be added to pkgname

Ocaml support is now (back) in its own sub-package.

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 ') .

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.
