如何使用Visual Studio 2010调试MATLAB .mex32/.mex64文件 [英] how to debug MATLAB .mex32/.mex64 files with Visual Studio 2010

问题描述

我有一个有关调试.mex32/.mex64文件的问题.假设现在我有一个名为test.cpp的文件:

I have a question related to debugging .mex32/.mex64 files. Suppose now I have a file named test.cpp:

#include "mex.h" 
#include <iostream>
void mexFunction(int nlhs, mxArray *plhs[],
    int nrhs, const mxArray *prhs[])
{
    mexPrintf("Hello Matlab, and this is a test program\n"); 
} 

然后我可以使用Visual Studio 2010编译和构建test.mex64.然后在matlab中，我可以编写以下脚本来测试该功能:

I can then compile and build test.mex64 with Visual Studio 2010.Then in matlab, I can write the following script to test the function:

clc; 
test;

现在假设我想调试test.mex64函数，该怎么办?已采用以下程序，但失败了:

Now suppose I want to debug the test.mex64 function, what should I do? The have adopted the following procedure, but failed:

1. 在VS2010的行mexPrintf开头处切换断点.
2. 使用VS2010，从调试"->附加到进程"中选择MATLAB.exe.
3. 运行MATLAB脚本clc; test;

1. Toggle break point at the begging of the line mexPrintfwith VS2010.
2. With VS2010 from Debug->Attach to Process... select MATLAB.exe.
3. Run MATLAB script clc; test;

我获得的错误消息如下:

The error message I have obtained is as follows:

The breakpoint will not currently be hit. No symbols have been loaded for this document. 

推荐答案

我找到了解决方案:创建.mexw64函数(在本例中为test.mexw64)时，我将其复制到了MATLAB工作目录中.为了调试此功能，将test.pdb文件也复制到MATLAB工作目录也很重要.完成之后，我可以进行调试.

I have found the solution: when I created the .mexw64 function (test.mexw64 in our case), I copied it to the MATLAB work directory. In order to debug this function, it is important to copy test.pdb file to the MATLAB work directory as well. After doing that, I can debug.
