problem when compiling c++ code

[llzlcl]

Thanks for your excellent work! But I met some problem when compiling the c++ code.

$ cmake .. -DCMAKE_CXX_COMPILER=g++-8 -DCMAKE_C_COMPILER=gcc-8

Could you please provide any instructions on it? Thank you in advance.

Hi, thank you and sorry for the delayed response!

Something seems wrong with nvcc paths, as /usr/lib/gcc/x86_64-linux-gnu/7/include/avx512fintrin.h is from g++-7 libraries, and you are specifically using g++-8 in the arguments.
It could be that nvcc is using gcc-7 as the backbone, then you can either update it to a newer nvcc or try switching to g++-7 for the rest of the project instead.

If this is still a problem, please write here.
