Arch Linux User Repository

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. I understand how older llvm libs repo packages do it, not sure yet if i agree with the approach.

• llvm-git

  has llvm , clang, compiler-rt, ocaml & python bindings, polly , lld , lldb . The provides for llvm-svn have been re-added to allow others maintainers to update their packages.

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"

llvm check now works, clang check however fails. I suggest to test without nocheck first, if build fails due to test failure add--nocheck .

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.

• 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 ?

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.
