Any successful WSL use? ("Windows Subsystem for Linux")

[JohnnyMarnell]

Hello @psobot old friend!

I can't seem to get pedalboard VST3's to load on WSL, in case anyone is equally masochistic and had success? (It works on Mac + Windows native and probably Linux native, but this plugin binary isn't Linux, plus I don't have a machine to test on hand).

Easy way to get more info here?

% scp /tmp/vst.py desktop_windows: ; scp /tmp/vst.py desktop_wsl:
% python3.12 /tmp/vst.py ; ssh desktop_windows 'python vst.py' ; ssh desktop_wsl 'python3.12 vst.py'

This simple hello world I'm using:

import os
import platform
from pedalboard import VST3Plugin
import sys


def vst_path():
    system = platform.system()

    if system == "Darwin":
        return "/Library/Audio/Plug-Ins/VST3/FabFilter Pro-Q 3.vst3"
    elif system == "Linux":
        if "microsoft" in platform.uname().release.lower():
            return "/mnt/c/Program Files/Common Files/VST3/FabFilter Pro-Q 3.vst3"
        else:
            raise Exception("No Linux binary, plus I no have-y machine-y")
    elif system == "Windows":
        return r"C:\Program Files\Common Files\VST3\FabFilter Pro-Q 3.vst3"
    else:
        raise Exception("Unknown environment")


print(f"OS {platform.system()} py {sys.version.split()[0]} is using {vst_path()}")
assert os.path.exists(vst_path()), "VST3 plugin not found"
plugin = VST3Plugin(vst_path())
print(f"Loaded {plugin.descriptive_name}")

@JohnnyMarnell VST plugin under linux and windows have different "implementations", so if you just try to run VST plugin meant for Windows in Linux it won't work. In addition to that I would add that generally loading, reading anything in WSL from under mnt can behave unexpectedly. For example I was recently doing some C/Rust practice and trying to chown/chmod compiled program in mnt using Makefile didn't work, moving the same code into wsl internal folder solved the issue.
