Can't install alvr-nvidia on Arch

[pflavio]

Hello guys

I'm receiving the following error when trying to install alvr-nvidia via the AUR (using yay):

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

Someone else has also posted the same issue in the comments on the AUR page here. Is there a way to fix it? I was able to install the regular ALVR from the AUR just fine (but it didn't work for me so I wanted to try the NVIDIA version for my RTX 3060).

Please send the full log

Well it kinda fixed itself I guess. I tried running it again to get you a fresh pair of logs and now it went through. Before opening the ticket I tried it three times with the same error each time however.

In any case my Quest 2 isn't getting discovered by alvr-nvidia either so I'm guessing no VR on Linux for me unfortunately. :(

Read our troubleshooting wiki

[pflavio]

@Vixea I did and compared screenshots and I noticed that SteamVR is not showing the ALVR addon! Everything from the toubleshooting guide (especially the Linux one) should be alright though. Trying the suggested workaround now. This issue can be closed however as the initial problem is gone.

Are you launching using the button in the dashboard? Have you checked that it isnt the flatpak version of steam? Maybe try installing steam-native-runtime

[pflavio]

No it wasn't Steam error but AVLR from AUR (specifically the NVIDIA version). I initially got that one since I have a 3060. Based on the recommendation in the text I downloaded the tar.gz version from releases and there it works as designed (so far). I can launch it, stream Steam and I'm currently downloading Pavlov to see if I can play, too.

[pflavio]

So I managed to get it to work and run Half Life Alyx, but without sound. Pavlov says it's starting but nothing happens unfortunately...

For future reference, I found what the fix was: after installing CUDA, you must log out, and then log back in (or reboot). This is so that CUDA gets added to PATH. Hope this helps others!

[pflavio]

Great good to know! That would have never occurred to me. I just attributed it to it fixing itself. :D Next time I'll keep that in mind (or maybe run a command to update the path directly?)
