Hi,

nvidia-cuda-toolkit depends on gcc-13, which won't be shipped in forky.
Please update to 15 or 16, or ideally use the default version (currently
GCC 15).

Cheers,
Emilio

Hi Emilio,

CUDA's 12.4 nvcc refuses anything newer than gcc-13.  crt/host_config.h:143:

  #if __GNUC__ > 13
  #error -- unsupported GNU version! gcc versions later than 13 are not
  supported! ...
  #endif

You could probably patch it out or overwrite it
by defining __NV_NO_HOST_COMPILER_CHECK
but it is not recommended by upstream.

The minimal valid configuration to fix the bug is probably driver 580
and CUDA 12.9 (with gcc-14 support).
To be safe, I would go with driver 580 and CUDA 13.0 (with gcc-15
support). Pre-Turing GPUs still run on 580, but CUDA 13.0 dropped
compilation support.
But Forky should probably ship something newer (e.g. To better support
local AIs etc ...)

Hi,

* Dominique Belhachemi [Wed Aug 05, 2026 at 07:55:23PM -0400]:

The latest CUDA version by now is 13.4.2, and NVCC version being
13.4.92, released as of 2026-09-16, see
https://developer.download.nvidia.com/compute/cuda/redist/redistrib_13.4.2.json.

As stated by Dominique, CUDA 13.0's NVCC Compiler supports GCC 15
and Clang 20 (see e.g.
https://developer.nvidia.com/blog/whats-new-and-important-in-cuda-toolkit-13-0/).

The latest CUDA version 13.4 also supports GCC 16 and Clan 22,
according to
https://developer.nvidia.com/blog/cuda-toolkit-13-4-adds-windows-on-arm-support-and-greater-control-over-shared-gpus/

Would be great to have a current version of CUDA in forky. :)
