C++ with CUDA project in CMake gives error: nvlink fatal : Could not open input file 'CMakeFiles/MY_APP.dir/src/MY_APP.cpp.o' (target: sm_35)

Question

你好，我正在处理一个 C++ 项目，并且有一个运行良好的 cmake 文件，直到我尝试将 cuda 添加到 C++ 项目中。我正在 NVIDIA Jetson Nano 上构建这个项目。

构建时出现此错误：

nvlink fatal : Could not open input file 'CMakeFiles/MY_APP.dir/src/MY_APP.cpp.o' (target: sm_35)

下方的其余错误如下所示：

CMakeFiles/MY_APP.dir/build.make:552: recipe for target 

'CMakeFiles/MY_APP.dir/cmake_device_link.o' failed
make[2]: *** [CMakeFiles/MY_APP.dir/cmake_device_link.o] Error 1
make[2]: Leaving directory '/home/me/Code/MyApp/build'
CMakeFiles/Makefile2:127: recipe for target 'CMakeFiles/MY_APP.dir/all' failed
make[1]: *** [CMakeFiles/MY_APP.dir/all] Error 2

Makefile:155: recipe for target 'all' failed
make: *** [all] Error 2
make: Leaving directory '/home/me/Code/MY_APP/build'

我运行我的 cmake 文件使用我称为 confgure.sh 的脚本，它看起来像这样：

#!/bin/sh

cmake -S . -B build -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.2 -DCMAKE_CUDA_COMPILER=/usr/local/cuda-10.2/bin/nvcc

我运行我的 make 文件使用了我称为 build.sh 的脚本，它看起来像这样：

#!/bin/sh

make -C build

我的 Cmake 文件如下所示：

我不知道如何将 CUDA 添加到我已经包含一堆 C++ 文件的项目中，我需要能够从 .cpp 文件调用我的 .cu 文件 main.cpp ，我需要在 CMake 中构建这座建筑，我正在 jetson nano 上进行。对解决此错误有帮助吗？

Answer 1

您混淆了很多与 CUDA 相关的定义和命令，包括 CMake 支持 CUDA 的早期“时代”的一些定义和命令。

除其他外：

您的 CMakeLists.txt 正在覆盖 CUDA 编译器位置的环境设置。
...实际上，无论如何您都不应该费心设置该位置，因为您已经设置了 CUDA 工具包根目录。
不要将 find_package(CUDA) 与 CMake 3.17 或 3.18 或更高版本一起使用。对于所有与工具包相关的路径，请使用 find_package(CUDAToolkit)`，它确实...好吧，更少但也更多。
不要使用 cuda_add_+后缀命令。由于 CMake 本机支持 CUDA，因此您可以使用常规 add_executable、add_library 等

您的 CMakeLists.txt 文件还有其他问题 - 并非所有问题都与 CUDA 相关，但这应该足以让您入门。不过，它本身可能无法解决您遇到的具体底线问题。

您可能想查看 public 个使用 CUDA 和最新 CMake 版本的存储库，以了解这是如何完成的。
