Build from AUR?

[mysteryx93]

Is this package available on Linux in the AUR? Every other package was there... only missing this one

[AkarinVS]

The included meson.build should work under Linux. Just make sure to have the correct llvm version (10 to 12, and 13 is not yet supported.)

If you want to compile this under Arch, you will need to downgrade LLVM since they've been shipping 13.x for months now.
There is a helper tool called downgrade which I have used to compile this plugin: https://aur.archlinux.org/packages/downgrade/

For me, I had to downgrade to 34) llvm 12.0.1 5 (the 5th version of 12.0.1 in the archives). For whatever reason, this plugin was not compiling with other versions of LLVM 12.x. This may have occurred due to a packing error, I do not know.

You may or may not have to downgrade sister packages such as llvm-libs, I did just to be safe.

You may be interested in this. This plugin is a soft requirement for https://github.com/DJATOM/vapoursynth-preview/blob/api-v4-support/vspreview/main.py and a few other functions.

ok. when go to home

Wow that was quick! Microsoft wasn't so quick to fix problems.

I still don't see it in my package manager, how long it takes to be available? I did run pacman -Syu

[sl1pkn07]

pacman not see the aur repository. you need download the PKGBUILD by hand and build yourself with makepkg or use a helper like yay or something

greetings

[mysteryx93]

ah but my "Add/Remove Software" supports it. Found the "Update" button. Working!

I hope all those VS AUR packages won't cause package conflicts... I was warned against using the AUR

[mysteryx93]

The AUR build doesn't seem to work

AttributeError: No attribute with the name akarin exists. Did you mistype a plugin namespace?

It's not getting loaded like the other plugins.

[mysteryx93]

OK that's strange. Simple script.

clip = core.akarin.Expr(clip, "x")

AttributeError: No attribute with the name akarin exists. Did you mistype a plugin namespace?

I do have /usr/lib/vapoursynth/libakarin.so that takes 44.9MB, alongside all the other plugins that do get loaded. Something wrong with that one?

I rebooted just to be sure, problem persists. That means corrupt library? Missing dependency, perhaps?

I asked about this on Discord; they could reproduce the problem but nobody has any idea what causes it. Since the lib file is there.

Does it have a runtime dependency on an older version of LLVM or it's only for compilation?

[mysteryx93]

aahhh I'd bet that the problem with vsakarin is that it uses LLVM to compile expressions on-the-fly, but needs an older version. That means that I need 2 versions of LLVM installed on my system side-by-side? How do I do that on arch-based linux?

[sl1pkn07]

that expression is compiled by library or program? with library maybe with LD_LIBRARY_PATH=>path of the llvm libraries<. if use a executable, IDK

[mysteryx93]

Probably we need llvmlibs-11 library. But simply installing that dependency still doesn't work.

@sl1pkn07 and add that path where? I'm trying to build with meson build and it's not finding llvm11-lib.

[mysteryx93]

Actually the problem may be that it was built with dynamic link to LLVM instead of being statically linked.

[mysteryx93]

I used downgrade on llvm; llvm-libs does need to be downgraded too. Once manually compiled, then it works. It still works after re-updating llvm and llvm-libs, so it will need to be tested on another computer that didn't have that manual intervention.
