不能在 Linux 的 Matlab 中包含 OpenCV 函数

Question

我有一个.cpp，我正试图在Ubuntu 14.04中使用MATLAB R2011a进行mex操作。该文件使用一些OpenCV函数并导入相应的库：

#include <opencv/cv.h>

我在Matlab中使用以下命令进行混合：

mex -I/usr/local/include FaceDetect.cpp

由于opencv库安装在/usr/local/include/opencv中。崩溃结果如下：

Warning: You are using gcc version "4.8.2-19ubuntu1)".  The version
     currently supported with MEX is "4.3.4".
     For a list of currently supported compilers see:

collect2: error: ld returned 1 exit status
     mex: link of ' "FaceDetect.mexa64"' failed.

我尝试过使用-L和-lcv进行编译，但它仍然会崩溃。我做错了什么？

计算机视觉系统工具箱现在包括一个OpenCV接口支持包。它包括MATLAB和OpenCV数据类型之间的转换例程库，以及使用OpenCV编译mex函数的简单方法。
