我正在尝试在调试模式、VS2013 社区、x64 中构建使用 caffe 的 C++ 应用程序。为了能够构建不需要 cuda 运行的版本，我添加到包装的每个 .cu 文件中，如下所示：
#ifndef CPU_ONLY
// .cu file contents
#endif
该项目在 CPU_ONLY 模式下构建并运行良好。取消定义 CPU_ONLY 标志，项目在发布模式下构建并运行正常，但在调试中，尝试编译 *.cu 文件时出现以下错误：
Compiling CUDA source file ..\..\src\caffe\layers\base_data_layer.cu...
>

> nvcc fatal : Stray '"' character in command line
COMMAND exited with code 1.
其中 COMMAND 是下面的 nvcc 编译器调用命令，为便于阅读而换行。

在添加 CPU_ONLY 标志之前，该项目能够在调试模式下成功构建。有任何想法吗？
