Arch Linux User Repository

The point was that llvm8 did not exist in repos. It does now, so I'm moving the dep to llvm8 and updating to 0.31.0. I still consider llvm=9 unresolved until llvmlite#523 is closed.

Well, LLVM 8 is tested and works with 0.31, so requiring LLVM 7 would be wrong there

This package now uses llvm7 again until llvmlite supports the current llvm in the Arch repositories.

I just noticed we can use llvm7 to build this pacakge for now. It's supported.

@plaxx: good catch! but if you have llvm 8.0 you don't the patch at all :-)

In order to upgrade to llvm 9, I needed to build and install a compatible package while I was still on 8. Only then I could upgrade to llvm 9.

I can "from numba import jit" with that PKGBUILD and llvm-libs 9, however I later run into some mysterious jit issues with bytecode parsing...

I can confirm that python-llvmlite can be built with llvm 9. Here is the PKGBUILD which I'm using.

But I don't know how to perform a full test. I only tested import llvmlite and it works fine.

@mschu: I just compiled llvmlite and numba in a clean chroot using the patch below (plaxx's). It works for me, at least the example in numba's homepage (function monte_carlo_pi). FWIW, here are the compilation logs for llvmlite and numba

@plaxx: good catch! but if you have llvm 8.0 you don't the patch at all :-)

Thanks for the updated PKGBUILD @a821 and the patch @krachyon. However, trying to compile the package on my system I realized there's a little logic mistake in the patch.

The final test should be (parenthesis to not the whole test not just the first test):

if not (out.startswith('9.0.') or out.startswith('8.0.') or out.startswith('7.0.') or out.startswith('7.1.')):

Otherwise you can't compile the package while still on 8.0.
