During building you may encounter lots of coredumps, slowing build down or even dramatically reducing the responsiveness of your system.

See https://wiki.archlinux.org/title/Core_dump for solutions/workarounds .

Archlinux currently has 3 llvm git implementations

  1. this package

    • see other pinned comments for details

  2. llvm-git

    • 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
    • binary versions in chaotic aur unofficial repository

  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

Why does this package exist ?

Llvm & aur llvm-git are intended to provide a full development environment of llvm/clang suite that can replace eachother completely (aur llvm-git adds some xtra functionality)

llvm-minimal-git is a stripped-down llvm trunk build with these goals :

  • llvm-libs-minimal-git must coexist with stable llvm-libs
  • provide what's needed for mesa trunk (it's a hard dependency for mesa-minimal-git and a possible dependeny for mesa-git)
  • provide basic llvm/clang compiler functionality on x86-64 architecture

Some of the things that are stripped out :

  • cross-compiling support
  • bindings for ocaml
  • bindings for go
  • lld , lldb and polly
  • documentation
  • examples
  • benchmarks

Maintainers (and users) should only depend on llvm-miminal-git after verifying it satisfies what they need.

When building this you are likely to see test failures in terminal output / logs.

The command used for the tests has been changed to continue regardless of failures. Incase you don't want to run the tests you can use --nocheck option of makepkg.

thank you for your response. I just tested this build using regular makepkg -si and it works so long as I set:

-D LLVM_PARALLEL_LINK_JOBS=1
-D LLVM_ENABLED_SHARED_LIBS=ON
-D LLVM_ENABLE_LLD=ON

in the PKGBUILD, but for some reason when trying with makechrootpkg -c -r $CHROOT it gives

CMake Error at cmake/modules/HandleLLVMOptions.cmake:412 (message):
  Host compiler does not support '-fuse-ld=lld'.  Please make sure that 'lld'
  is installed and that your host compiler can compile a simple program when
  given the option '-fuse-ld=lld'.
Call Stack (most recent call first):
  CMakeLists.txt:1019 (include)

I'm very new to clean chroot building and recently moved away from using AUR helpers, so I'm struggling with researching how to fix this. I set up the chroot according to the wiki, but maybe there was something non-trivial I'm meant to do for the compiler to work correctly.

Lone_Wolf commented on 2024-10-14 10:55 (UTC)

No build issues with rev 20.0.0_r514923.bec839d8eed9 .

Could be an upstream issue, try again. If it still fails look in the aur/llvm-minimal-git folder for files ending with .log .

building in a clean chroot fails, but error is not descriptive. Steps to reproduce

[base] [mdupont@arch-g14 ~] :) cd aur 
[base] [mdupont@arch-g14 aur] :) cd llvm-minimal-git
[base] [mdupont@arch-g14 llvm-minimal-git] (master) :) makechrootpkg -c -r $CHROOT 
...
[ 43%] Built target obj.clangBasic
make: *** [Makefile:156: all] Error 2
make: Leaving directory '/build/llvm-minimal-git/src/_build'
==> ERROR: A failure occurred in build().
    Aborting...
==> ERROR: Build failed, check /home/mdupont/chroot/mdupont/build

this error is not descriptive enough for me to diagnose the problem on my own. Any hints?

@wustdsh I'm so caught up in my things that I didn't bother to look and just reported.

Original line: rm "$pkgdir"/usr/lib/clang/19/lib/{i386-pc-linux-gnu,x86_64-pc-linux-gnu}/*.a

Only removed i386-pc-linux-gnu

Left:

rm "$pkgdir"/usr/lib/clang/19/lib/x86_64-pc-linux-gnu/*.a

Builds just fine. @Lone_Wolf

ps,

curl is currently broken (curl-8.7.1-3) and git+https will fail downloading the source. Downgrading curl (8.6.0-4) works.

Lone_Wolf commented on 2024-03-25 21:42 (UTC)

Did you include base-devel when creating the chroot ?

You're not supposed to add makedepends through arch-nspawn but should let makechrootpkg determine makedepends & depends at build time. However if you do want to add makedeps that way why did you leave out libffi, ncurses, libxml2 and libxcrypt ?

Which revision are you trying to build ?

jansalleine commented on 2024-03-25 09:12 (UTC)

I get a CMake error when trying to build this in a clean chroot:

CMake Error: The inter-target dependency graph contains the following strongly connected component (cycle):
  [... a ton of targets ...]
At least one of these targets is not a STATIC_LIBRARY.  Cyclic dependencies are allowed only among static libraries.
CMake Generate step failed.  Build files cannot be regenerated correctly.

Steps to reproduce:

  • Set up clean chroot as described in the wiki
  • install dependencies: arch-nspawn $CHROOT/root pacman -S git cmake libedit python python-setuptools
  • git clone https://aur.archlinux.org/llvm-minimal-git.git
  • cd llvm-minimal-git and then makechrootpkg -c -r $CHROOT

I have encountered problems during building that indicate options=('!lto') is ignored by makepkg but OPTIONS=('!lto') does work.

See https://bbs.archlinux.org/viewtopic.php?id=293226 for more info

The issue was not having !debug in the PKGBUILD, corrected.

Lone_Wolf commented on 2024-03-12 09:42 (UTC)

thanks for the headsup, will look into it.
