Question

操作系统：ubuntu 16.04 CUDA：7.5 Cudnn：5

我正在关注使用gpu安装caffe的this教程。在这里，我想要安装opencv 3.1。但是，当系统中已经安装了CUDA时，opencv的编译就会出错。

尝试make opencv 3.1时遇到的错误是：

/usr/include/string.h: In function ‘void* __mempcpy_inline(void*, const void*, size_t)’:
/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope
   return (char *) memcpy (__dest, __src, __n) + __n;
                                          ^
CMake Error at cuda_compile_generated_gpu_mat.cu.o.cmake:266 (message):

make[2]: *** [modules/core/CMakeFiles/cuda_compile.dir/src/cuda/cuda_compile_generated_gpu_mat.cu.o] Error 1

make: *** [all] Error 2

我尝试通过向其添加行set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES")来更改opencv 3.1的CMakeLists.txt。另外，我查看了更改/usr/include/string.h提供的here的建议。但我已经有了该文件的更新版本。我无法构建opencv 3.1，因此，Caffe。
