Question

我正在尝试使用Windows上的CMake编译CUDA项目。我不熟悉make或CMake，过去几天我做了一些阅读，但我仍然无法解决这个问题。我收到以下错误消息：

Chri@Riemann-PC /cygdrive/c/Apps/ThirdParty/MAGMA/magma-2.0.1/build64

使用make VERBOSE = 1命令，我收到以下错误：

它仍在使用gcc编译器（-ccbin /usr/bin/gcc.exe）。

我进入了文件：C:\Apps\ThirdParty\cygwin64\usr\share\cmake-3.3.2\Modules\FindCUDA.cmake并添加了以下行：

set(VS_DIR "C:\\Program Files (x86)\\Microsoft Visual Studio 12.0\\VC\\bin")
message(${VS_DIR})
set(CUDA_NVCC_FLAGS "-ccbin ${VS_DIR}" CACHE STRING "Semi-colon delimit multiple arguments.")

我还在nvcc.profile文件中添加了以下行：

CUDA_NVCC_FLAGS += -ccbin "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin";

仍然没有运气。我花了几天时间试图解决这个问题。我很感激在这件事上提供任何帮助。

在FindCUDA中设置主机编译器的选项为CUDA_HOST_COMPILER，请参阅FindCUDA documentation。

尝试

set(CUDA_HOST_COMPILER "<path to compiler executable>")

或者在调用cmake命令时设置它

cmake .. -DCUDA_HOST_COMPILER=<path to compiler executable>

我猜CUDA_HOST_COMPILER选项会覆盖ccbin的{{1}}设置。对于其他选项，您可以按照您尝试的方式使用CUDA_NVCC_FLAGS。（因此，标题具有误导性。这不是如何设置CUDA_NVCC_FLAGS的问题。）

我经常在Linux上使用它，但是我没有Windows环境来测试它。

使用CMake设置CUDA_NVCC_FLAGS
