Not sure which version of nvidia-cuda-toolkit I should be using (all are marked ~amd64) but upgrading to 12.8 caused several errors like this when compiling opensubdiv: #$ "/usr/x86_64-pc-linux-gnu/gcc-bin/14"/gcc -D__CUDA_ARCH__=520 -D__CUDA_ARCH_LIST__=520 -D__NV_LEGACY_LAUNCH -c -x c++ -DCUDA_DOUBLE_MATH_FUNCTIONS "-march=alderlake" "-mabm" "-mno-cldemote" "-mno-kl" "-mno-sgx" "-mno-widekl" "-mshstk" "--param=l1-cache-line-size=64" "--param=l1-cache-size=32" "--param=l2-cache-size=30720" "-O2" "-pipe" "-fno-diagnostics-color" "-ggdb" -march=alderlake -mabm -mno-cldemote -mno-kl -mno-sgx -mno-widekl -mshstk --param=l1-cache-line-size=64 --param=l1-cache-size=32 --param=l2-cache-size=30720 -O2 -pipe -fno-diagnostics-color -ggdb -O2 -Wno-psabi -I"/opt/cuda/include" -I"/var/tmp/portage/media-libs/opensubdiv-3.6.0-r2/work/OpenSubdiv-3_6_0/opensubdiv" -I"/var/tmp/portage/media-libs/opensubdiv-3.6.0-r2/work/OpenSubdiv-3_6_0/glLoader" "-I/opt/cuda/bin/../targets/x86_64-linux/include" -m64 "/var/tmp/portage/media-libs/opensubdiv-3.6.0-r2/temp/tmpxft_00005c27_00000000-6_cudaKernel.cudafe1.cpp" -o "/var/tmp/portage/media-libs/opensubdiv-3.6.0-r2/work/OpenSubdiv-3_6_0_build/opensubdiv/CMakeFiles/osd_static_gpu.dir/osd/./osd_static_gpu_generated_cudaKernel.cu.o" In file included from /opt/cuda/include/crt/math_functions.h:5994, from /opt/cuda/include/crt/common_functions.h:303, from /opt/cuda/include/crt/host_runtime.h:285, from /var/tmp/portage/media-libs/opensubdiv-3.6.0-r2/temp/tmpxft_00005c27_00000000-6_cudaKernel.cudafe1.stub.c:8, from tmpxft_00005c27_00000000-6_cudaKernel.cudafe1.stub.c:1: /opt/cuda/include/crt/math_functions.h:6006:1: error: declaration of ‘double sinpi(double)’ has a different exception specifier 6006 | __func__(double sinpi(double a)); | ^~~~~~~~ /opt/cuda/include/crt/math_functions.h:2557:15: note: from previous declaration ‘double sinpi(double) noexcept’ Reproducible: Always Steps to Reproduce: 1.
