GZDoom can't start anymore - CommandLine Error: Option 'help-list' registered more than once

[Vaults]

Hello there,

Unfortunately the program has completely stopped working for me on Linux Mint 20.1. I can only run GZDoom through WINE. Whenever I boot up the program with every kind of configuration this happens in the logs (I'm using a RX 6900 XT and it started since I installed it into my machine):

I'm suspecting it has to do with conflicting LLVM versions. The ones I have installed are

$ apt list --installed | grep -i llvm

libllvm11.0-amdgpu/unknown,now 1:11.0-1247438 amd64 [installed,automatic]
libllvm11.0-amdgpu/unknown,now 1:11.0-1247438 i386 [installed,automatic]

libllvm11/focal-updates,now 1:11.0.0-2~ubuntu20.04.1 i386 [installed,automatic]

Is there a known workaround for the time being?

The new AMD drivers for Ubuntu (v21.20) have fixed the issue. I will now close it.

The versions do not conflict any longer which could have been the problem

$ apt list --installed | grep -i llvm

libllvm11/focal-updates,now 1:11.0.0-2~ubuntu20.04.1 amd64 [installed]

Hi, I'm back 😅

It seems the last version just was okay coincidentally. I'm having the same problem with the AMDGPU (open source variant) on version 21.30.

$ apt list --installed | grep -i llvm

This shouldn't have anything to do with llvm since GZDoom doesn't depend on it. I believe those messages are coming from the system trying to capture a core dump or something like that. The point it's crashing at is trying to initialize OpenGL or Vulkan depending on your ini settings, so definitely something is up with the drivers.

Try using gzdoom +vid_preferbackend 1 to switch to Vulkan if you haven't already tried that.

GZDoom runs fine on my Radeon Pro W6600, but I took the route of updating the kernel to 5.13 and using the Kisak mesa stable PPA on Ubuntu 21.04. I haven't personally installed the AMD provided drivers in years, but in theory the open source option there should provide similar results. Quite curious.
