Arch Linux User Repository

Any reason to not use the current 2023.7 (https://github.com/google/shaderc/releases/tag/v2023.7) version ?

This one build correctly and is aligned with 64 bit version available in official arch repo.

Can't build it:

lib32-shaderc - exit status 4

FYI: I know this package has been outdated for sometime. I've been waiting for the native package to receive its update. Since it has been so long, I'll produce a temporary update to bring it on par with the native, but another one will probably be out short after.

Fails to build. Please apply:

As to why this is needed, your guess is as good as mine.

I've been trying to build lib32-gst-plugins-bad for the last couple of days, and after yesterday's update to lib32-spirv-tools which finally allowed that package to be built, I've now been getting this new error while trying to build lib32-shaderc:

...

...and then a bunch of similar /usr/bin/ld errors reporting undefined references to various SPIRV functions.

I also noticed that while building the required lib32-glslang I got this (the package built successfully though):

-- spirv-tools not linked - illegal SPIRV may be generated for HLSL

Could this be the reason for the SPIRV errors? Is anyone else getting these errors?

Same issue for me here on Manjaro 21.0 with version 2020.4 as for @MarsSeed.

Update is on its way. It seems I missed a few updates, I'll have a look at my feeds to be sure I don't miss anymore.
