Arch Linux User Repository

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.

llvm added to provides

Is a "provide llvm" missing? I get

New packages 'llvm' and 'llvm-git' are in conflict.

on update of kdevelop-git

yeah, I meant to edit my post after I cloned your git and compiled it, but it slipped my mind.

https://aur.archlinux.org/cgit/aur.git/commit/?h=llvm-git&id=d9c33f8954a8a4c9f39d6f24402f28df018f1b5c

Without python-sphinx-automodapi build failed for documentation. after that was added lldb was found to be needed also.

Packages that don't build documentation (like llvm-minimal-git) have no need for either,

Why is lldb a makedepends, and when was it added, I do not see a commit for it here? maybe I'm missing something.

lldb is a makedepend and requires llvm-libs, clang etc.

Once llvm-git building has finsihed those are no longer needed.

Building in a clean chroot solves this, makepkg also can separate build and install.

Is llvm-git already installed when you run pikaur ? If yes, try removing it.

If no, check pikaur documentation if it can separate build and install.

: CommandLine Error: Option 'polly-detect-profitability-min-per-loop-insts' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options

upstream issue, will check if it has been reported after weekend.

A different problem: lldb cannot be resolved. I would expect that it can be installed? Why is that?

Is that reproducible for you guys? or is it a local environment problem?

@Sinistar,
Thanks for the update. PKGBUILD modified accordingly.
