Hi all, I no longer use this package and have no interest in maintaining it. Before disowning it I'd ideally like to make someone a co-maintainer. Please reach out if you're interested. Thanks!

Hi @BenTheTechGuy, thanks for your fix for CUDA 13! I've partially copied over the diff from your PR, but won't change the CMake sources until this is merged upstream.

Below is a diff that will make this package work on CUDA 13+ and GCC 14+. The contents of cuda-13-support.patch is the changes from PR #211, which you can get in patch file form at https://github.com/xmrig/xmrig-cuda/pull/211.patch.

Sorry @edombek, unfortunately cuda 12.9 and specifically gcc14 is incompatible with xmrig-cuda. I am running into various compilation issues. I've opened an issue with upstream: https://github.com/xmrig/xmrig-cuda/issues/208.

Why gcc13 not in deps?(

can compile with the latest cuda 12.8:

/opt/cuda/include/crt/math_functions.h:5992:1: error: declaration of ‘double cospi(double)’ has a different exception specifier
 5992 | __func__(double cospi(double a));
      | ^~~~~~~~
/opt/cuda/include/crt/math_functions.h:6010:1: error: declaration of ‘float sinpif(float)’ has a different exception specifier
 6010 | __func__(float sinpif(float a));

it seems a conflict with glibc function types

if anyone find issues running xmrig-cuda against cuda 12.5 remove cuda 12.5 and install cuda 12.4. just change the PKGBUILD to match cuda 12.4 or compile xmrig-cuda manually applying the patch and using the same commands on the PKGBUILD

Hi, I've pushed a fix to PKGBUILD, it build now with CUDA 12.5.0.

Thanks @agowa for your analysis, I took your suggestions and applied them to CMake files directly.

Sorry @sidicer, I didn't see your comment sooner, thanks for looking more deeply at LTO. I've added -ffat-lto-objects to the CMake flags.

Using this gcc package: https://aur.archlinux.org/gcc12.git and this line cmake -DCMAKE_CXX_FLAGS="-ffat-lto-objects" -DCUDA_LIB=/usr/local/cuda/lib64/stubs/libcuda.so -DCUDA_TOOLKIT_ROOT_DIR=/opt/cuda -DCMAKE_C_COMPILER=/usr/bin/gcc-13 -DCMAKE_CXX_COMPILER=/usr/bin/g++-13 -S . -B build makes it compile successfully again.

/opt/cuda/bin/gcc and /opt/cuda/bin/g++ appear to no longer exist. For me this cmake command worked: cmake -DCMAKE_CXX_FLAGS="-ffat-lto-objects" -DCUDA_LIB=/usr/local/cuda/lib64/stubs/libcuda.so -DCUDA_TOOLKIT_ROOT_DIR=/opt/cuda -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_CXX_COMPILER=/usr/bin/g++ -S . -B build

regardless of that the actual build afterward still fails because ArchLinux ships GCC 14.1 and that is apparently incompatible... I get the same error as in this forum post and their resolution is basically "there is none, it's not supported."....

@hv15 I was building on a GTX780 for testing purposes which uses 11.4 Cuda version, but I installed the latest 12.* Cuda package on the system.
Will remove everything, install 11.* Cuda and update if that worked

But just a heads up as I do not think that was the issue as after building on RTX3080 with latest CUDA i got the same undefined symbol: blake256_hash error.
Hoping for a random missing library or a package 🤞

UPDATE:

Replacing -fno-lto flag with -ffat-lto-objects links libraries but uses LTO which is required for the blake256_hash to build. Currently on RTX3080 machine I was able to build xmrig-cuda and use it with this.
Apologies @hv15 for not investigating more at first

GTX780 not successful
