Question

我们有一个名为FaceTracker的项目是用cpp编写的，我们需要从另一个用matlab编写的项目中调用它。我们成功地使用“mex”和“mexfunction”（用c编写）从matlab调用单个函数。当我们尝试调用整个项目时，我们添加了以下源文件：

#include "mex.h"
#include "FaceTracker.h"

void mexFunction(int nlhs, mxArray *plhs[],
int nrhs, const mxArray *prhs[])
{
... // code
/* Call the "main" C++ subroutine. */
FaceTracker( buflen, input_buf);
}

并尝试通过输入以下内容在matlab中编译它：“mex mexFile.cpp” 但是我们遇到了以下错误：

如何解决这些错误？提前谢谢。

Answer 1

您将必须使用-I选项指定mex编译函数的所有必需包含路径，请参阅help mex.以下是一个示例：

 mex -v -g -IC:\Users\hodhod\Documents\Jam3a\PROJECT-2012!!\FindSymetryInFaces\FaceTracker\FaceTracker\SomeMissingIncludes mexFile.cpp

从Matlab调用Cpp项目
