https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241550 Bug ID: 241550 Summary: Base Clang can't compile trivial CUDA program. Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: arrowd@FreeBSD.org I've obtain CUDA headers from NVIDIA distribution [1] and tried using Clang= to compile simple program. However, I got errors from CUDA's internal headers saying: In file included from <built-in>:1: In file included from /usr/lib/clang/9.0.0/include/__clang_cuda_runtime_wrapper.h:204: /usr/home/arr/cuda/var/cuda-repo-10-0-local-10.0.130-410.48/usr/local/cuda-= 10.0//include/crt/math_functions.hpp:2910:7: error: no matching function for call to '__isnan' if (__isnan(a)) { ^~~~~~~ /usr/lib/clang/9.0.0/include/__clang_cuda_device_functions.h:460:16: note: candidate function not viable: call to __device__ function from __host__ function __DEVICE__ int __isnan(double __a) { return __nv_isnand(__a); } ^ I searched the net a bit and found following upstream commit [2]. Asking th= ere, I was told that it due, citing, > FreeBSD does not provide *host*-side __isnan(double) -- the error compla= ins that it's the host code that tried to use __isnan and failed when overl= oad resolution produced a device variant. Can anything be done about this? Sorry if this PR is not relevant for FreeB= SD.
