我刚刚安装了 CUDA 并一直在关注http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-mac-os-x/index.html

一切正常，直到我尝试将 deviceQuery 等示例代码复制到 ~/Desktop 并编译。

我在编译时收到以下错误：

/Developer/NVIDIA/CUDA-5.5/bin/nvcc -ccbin g++ -I../../common/inc  -m64 -Xcompiler -arch -Xcompiler x86_64   -gencode arch=compute_10,code=sm_10 -gencode arch=compute_20,code=sm_20 -gencode arch=compute_30,code=sm_30 -gencode arch=compute_35,code=\"sm_35,compute_35\" -o deviceQuery.o -c deviceQuery.cpp
deviceQuery.cpp:23:25: error: helper_cuda.h: No such file or directory
deviceQuery.cpp: In function ‘int main(int, char**)’:
deviceQuery.cpp:111: error: ‘SPRINTF’ was not declared in this scope
deviceQuery.cpp:116: error: ‘_ConvertSMVer2Cores’ was not declared in this scope
deviceQuery.cpp:206: error: ‘checkCudaErrors’ was not declared in this scope
deviceQuery.cpp:230: error: ‘checkCudaErrors’ was not declared in this scope
deviceQuery.cpp:241: error: ‘checkCudaErrors’ was not declared in this scope
make: *** [deviceQuery.o] Error 1

该代码将在CUDA目录中编译并运行，很明显编译器找不到helper_cuda.h，我也找不到，有人有解决方案吗？

如您的编译选项所示-I../../common/inc，helper_cuda.h位于$CUDA_HOME/samples/common/inc/.

如果要将示例复制到自定义位置，则必须复制整个目录，或修改一些代码/编译选项以在目录samples中包含人员。common/

NVIDIA CUDA Toolkit 包含源代码形式的示例程序。您应该通过更改为 ~/NVIDIA_CUDA-8.0_Samples 并键入 make 来编译它们。生成的二进制文件将放在 ~/NVIDIA_CUDA-8.0_Samples/bin 下

请确定：

$ export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}

$ export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64\ ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

$ nvcc -V

应该显示版本。

$ cd ~/some_path/NVIDIA_CUDA-8.0_Samples

$ make
