将 OpenCV 源代码编译到 Matlab

Question

我正在尝试在 Matlab 中编译 C++ 代码。源代码使用 OpenCV 库。 当我写：

mex myfile.cpp

我收到以下错误：

致命错误C1083：无法打开包含文件：'opencv2/opencv.hpp'没有这样的文件或目录

我正在使用 Matlab r2012b 并在 Windows 7 上安装 Visual c++ 2010。

请问有什么解决办法吗？

谢谢。

编辑：我执行了以下操作，但出现另一个错误：

 mex -v -largeArrayDims Calib.cpp -I"C:\opencv\build\include" ...

Answer 1

您应该将包含标志和链接库添加到命令行。也就是说，

mex myfile.cpp -I header_path -l opencv_libraries

Answer 2

请尝试：

mex -largeArrayDims Calib.cpp -IC:\opencv\build\include -LC:\opencv\build\x86\vc10\lib...
 -l opencv_calib3d240d -l opencv_core240d -l opencv_highgui240d -l opencv_imgproc240d

顺便说一句，您链接 opencv_d.lib 而不是 opencv_.lib 文件是否有特殊原因？
