Несмотря на то, что уже был задан почти идентичный question, ответ для OSX и больше не выполняется (и в любом случае очень хаки).
Проблема заключается в том, что при компиляции cuda с clang на окнах есть тонны переопределений в math_functions.hpp.
С некоторыми исследованиями, по-видимому, cuda решил поместить свои функции math_functions.hpp и math_functions.h в namespace std (это даже законно?) и столкнулся со всеми функциями libstdС++ в cmath и создал собственные заголовки для компиляции CUDA.
Как я могу справиться с этим? Предпочтительно не с хакерским способом, показанным в предыдущем вопросе?
Боковое примечание
В соответствии с clang документация, clang может перегружаться на основе квалификаторов __global__/__device__, не должен ли код просто компилироваться в любом случае?

Версии:
clang 4.0.0 (построено как this)
libstdС++ пришел из gcc 7.1.0
