subj; It looks like the assumption in the ebuild comments is not true anymore: 97 # this is non-fatal and libomp checks for CUDA conditionally 98 # to ABI, so we can just ignore passing the wrong value 99 # on non-amd64 ABIs So the offloading should be enabled only for the amd64 ABI. Reproducible: Always Steps to Reproduce: 1. USE="cuda offload abi_x86_32" emerge --info '=sys-libs/libomp-13.0.0::gentoo' Actual Results: Configuration error Expected Results: Compilation

What nvidia-cuda-toolkit version are you using? I'm surprised you have /usr/lib/libcuda.so.
(In reply to Michał Górny from comment #5) > What nvidia-cuda-toolkit version are you using? I'm surprised you have > /usr/lib/libcuda.so. /usr/lib/libcuda.so is installed by nvidia-drivers[abi_x86_32], not nvidia-cuda-toolkit

As Ionen Wolkens noticed the libcuda.so is installed by nvidia-drivers: $ equery b /usr/lib/libcuda.so * Searching for /usr/lib/libcuda.so ... x11-drivers/nvidia-drivers-495.44 (/usr/lib/libcuda.so.495.44) x11-drivers/nvidia-drivers-495.44 (/usr/lib/libcuda.so -> libcuda.so.495.44)
Ok, it turned out I couldn't reproduce because I had ccache enabled... and the stupid package assumes that llvm-link must be present in the same directory as the compiler. Since it wasn't present in the ccache shadow directory, the check for llvm-link failed and it disabled nvidia stuff.

Check CHOST to determine whether to enable them.
