如何在CMake中添加WSL下的CUDA编译器路径？

Question

我在Windows上使用Ubuntu (在WSL中)，我有CMake 3.10.1和CUDA工具包9.0。当我跑的时候

cmake ..

我发现了一个错误：

CMake Error at CMakeLists.txt:5 (project):
  No CMAKE_CUDA_COMPILER could be found.

  Tell CMake where to find the compiler by setting either the environment
  variable "CUDACXX" or the CMake cache entry CMAKE_CUDA_COMPILER to the full
  path to the compiler, or to the compiler name if it is in the PATH.

是否可以将数据自动化系统( CUDA )和CMake链接到WSL中，我如何将路径添加到CUDA？

Answer 1

您可以使用：

cmake -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.1 ..

只需将路径更改为安装的位置即可。

cuda可以通过命令安装在WSL上：

sudo apt-get install nvidia-cuda-toolkit

然后，cmake可以找到构建的路径。但是无法在WSL上运行可执行文件，因为Nvidia还不支持。
