Hello @solonovamax, Thank you for your report. I've updated package to 4.3.0

Hi, the package is currently out of date due to cycles having been updated to 4.3.0. Further, the package build is broken. Here is a patch file which updates to 4.3.0 (& because of that fixes the build issue):

With this patch, the package successfully builds on my machine.

Building with gcc12 works

@FabioLolix Thanks for the devtools tip, I bow low before your science of packaging!

Bad news, however, about the issue: it seems to be directly related to cuda12.2 and gcc13:

https://forums.developer.nvidia.com/t/identifier-float32-is-undefined-etc-cuda-12-2-0-gcc-13-1/258930

https://forums.developer.nvidia.com/t/seeking-workaround-for-compiling-code-in-a-system-with-gcc-13/262333

As a temporary workaround, I suggest using gcc12, which is still available in the repo (prefixing with CC=cc-12 CXX=g++-12). Can you check it's ok for you?

@howetuft you can reproduce by adding cuda and optix to makedepends and build with devtools which will build in a chroot instead of your system

Hello @adro,

I cannot reproduce, but I use a previous version of cuda (11), due to old GPU.

To investigate, can you please:

1. Report your version of cuda compiler: /opt/cuda/bin/nvcc --version

2. Paste bin the full error log?

Thank you!

Can confirm that fails to build when cuda and optix are installed, without builds fine

Hi, could you try building the package with an updated system? I'm getting these errors:

/usr/include/stdlib.h(141): error: identifier "_Float32" is undefined extern _Float32 strtof32 (const char __restrict __nptr, ^ /usr/include/stdlib.h(147): error: identifier "_Float64" is undefined extern _Float64 strtof64 (const char __restrict __nptr, ^ /usr/include/stdlib.h(153): error: identifier "_Float128" is undefined extern _Float128 strtof128 (const char *__restrict __nptr, ^ Error limit reached. 100 errors detected in the compilation of "/home/adro/.cache/yay/cycles-standalone/src/cycles/src/kernel/device/cuda/kernel.cu". Compilation terminated.

Worked! Thanks!

can you confirm package builds ok for you without usd?

Yes it build fine without it

But I didn't catch the point about usd: what is an "an automagic depends"?

It is a depends that is being enabled at build time but is not present in depends=()

see this https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Automagic_dependencies

That is also happening because packages not build in an isolated environment (not build with devtools) dinamically pick-up libraries

Pratical example https://aur.archlinux.org/packages/strawberry-qt5?O=10#comment-806553

To be honest the risk with usd is very low because there are several problems building that package
