I find some errors when i compile with cuda 13.2.1, I tried/sd: c++14, but it didn’t work.

I didn’t have any trouble compiling it on godbolt. There may be a problem with your machine setup.

3

My compilation environment is MSVC2022 with std:c++17, cuda13.2.1

4

I have resolved the problem, thank you.

5

@wanli.teng I have encountered the same problem. How did you resolve the issue?

6

1、include add C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v13.2\include\cccl

because the include of thrustmove to cccl folder

2、use c++17 or above：-std=c++17 -Xcompiler “/std:c++17”,set in cuda c/c++ command line

3、use /Zc:preprocessor in cuda c/c++ additional compiler options

7

Thanks! We were already doing those. In our case, it was because the file was being compiled with MSVC rather than nvcc (not sure whether the fact this used to work using the 12.x CUDA Toolkit was just luck or whether something has changed in CUDA 13.x)
