I added a patch that fixes the GCC 13 build.

WTF. Okay so the pkgbuild is now succeeding, even though I didn't re-clone the repo.

It failed with the same old error I posted earlier that you get with GCC 13 (even though the PKGBUILD was updated to use GCC12). So then I just did a cd ~/tmp/makepkg/nvlax-git/src/nvlax and then ran the cmake and make commands manually and it built.

So then I cd-ed back into ~/tmp/nvlax-git and ran makepkg -s and it succeeded.

So then I deleted the makepkg/nvlax-git directory and the AUR repo directory, and re-cloned and ran makepkg -s and it worked again.

I think for some reason it was using GCC13 and not picking up the envar, but it's working now.

That's weird, it used to work, I've patched files with it before, but this was back on like 525 months ago or something, like when obs-nvfbc still worked.

Oh well, at least it's applying on updates now.

ventureo commented on 2023-06-16 15:25 (UTC)

This is normal behavior for nvlax because it does not check if the library has already been patched.

Anyway, this should all be addressed to upstream, but I'm not sure it will ever be considered.

Running the literal identical command from the pacman hook fails as well, even when running as root:

# /bin/sh -c 'nvlax_encode -i /usr/lib/libnvidia-encode.so -o /usr/lib/libnvidia-encode.so; nvlax_fbc -i /usr/lib/libnvidia-fbc.so -o /usr/lib/libnvidia-fbc.so':

As for the patch failing, it does currently succeed to patch NvFBC when upgrading/installing nvidia-utils, but it fails when trying to run nvlax manually:

/bin/sh -c "nvlax_fbc -i /usr/lib/libnvidia-fbc.so -o /home/matt/tmp/libnvidia-fbc.so":

Can't even rebuild it.

This is with makepkg, not yay.

I can confirm, it seems to be working on 535.53.04.

ventureo commented on 2023-06-16 15:02 (UTC)

@gardotd426 I'm not really interested in arguing, but it works for me nonetheless.

@ventureo if you're saying it works on 535.53.04, I believe you're mistaken.
