works ok with llvm (19)

I needed to install llvm18 and add export LLVM_CONFIG=/usr/bin/llvm-config-18 before pkgver() to get it building now that Arch has shipped llvm 19

btw that issues has been deleted

Someone uploaded a pkgbuild which use llvm14 which is in repo instead of llvm15 which is on AUR

https://aur.archlinux.org/packages/vapoursynth-plugin-vsakarin-llvm14-git https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=vapoursynth-plugin-vsakarin-llvm14-git

What do you say about using that llvm version?

If anyone get this Reactor: Unknown command line argument '-x86-asm-syntax=intel'. Try: 'Reactor --help' Reactor: Did you mean '--stats-json=intel'? error in Av1an when using VSAkarin Plugin, merge this PR into it while building: https://github.com/AkarinVS/vapoursynth-plugin/pull/23

https://github.com/AkarinVS/vapoursynth-plugin/issues/24

Surely this plugin requires llvm15 specifically?

Has issues with llvm16 building and working due to the need for methods now private. Was able to get around this with llvm15 (you need it, not just the llvm15-libs package) and the extra line: export LLVM_CONFIG=/usr/bin/llvm-config-15 before the pkgver function.

Hi, can you disable statically linking LLVM with -Dstatic-llvm=false.
It was added here: https://github.com/AkarinVS/vapoursynth-plugin/pull/8.

This reduces the .so size by 40M and fixes conflicts.
