Microsoft Visual C ++ 2008和R2007b的Mex类型

问题描述

我想对vs2008和matlab2007b使用mex类型.我在下面尝试了代码.

i want to use mex type for vs2008 and matlab2007b.i tried code below.

#include<iostream>
#include <matrix.h>
#include<mex.h>
using namespace std;
void hello(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
  mexPrintf("Hello World!\n");
}

并得到此错误

'matrix.h': No such file or directory

而我在下面的Matlab Commond Win中写道

and i wrote below in matlab commond win

mex -setup
Please choose your compiler for building external interface (MEX) files: 

Would you like mex to locate installed compilers [y]/n? y

Select a compiler: 
[1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2007b\sys\lcc 

[0] None 

Compiler: 

那么使用mex类型应该怎么做?

so what is should do to use mex type?

谢谢

推荐答案

我看到两个问题:

1. 您不需要包含<matrix.h>，<mex.h>中包含了<matrix.h>.尝试:include "mex.h"而不是<mex.h>，然后删除include <matrix.h>.
2. mex -setup找不到您的Microsoft Visual C ++ 2008编译器.

1. You don't need to include <matrix.h>, <matrix.h> is included inside <mex.h>. Try: include "mex.h" instead of <mex.h>, and remove include <matrix.h>.
2. mex -setup could not locate your Microsoft Visual C++ 2008 compiler.

选择菜单应如下所示:

Please choose your compiler for building external interface (MEX) files:

Would you like mex to locate installed compilers [y]/n? y

Select a compiler:
[1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2007b\sys\lcc
[2] Microsoft Visual C++ 2008
[0] None

Select a compiler:
[1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2007b\sys\lcc
[2] Microsoft Visual C++ 2008
[0] None

由于Visual 2008比Matlab R2007b更新，因此Matlab无法自动定位Visual2008.

Since Visual 2008 is newer than Matlab R2007b, Matlab can't automatically locate Visual 2008.

有一种方法可以手动添加.

There is a way to add it manually.

请考虑:由于我没有Matlab R2007b，我无法完全验证以下说明:

Please consider: I could not fully verify the following instructions because I don't have Matlab R2007b:

分步说明:

1. 转到 https://www.mathworks.com/matlabcentral/fileexchange/18508-microsoft-visual-studio-2008-mex-and-mbuild-setup-files
2. 下载zip文件VS2008Matlab.zip(按页面右上方的下载zip"蓝色按钮).
3. 解压缩zip文件.
4. 将文件夹内容VS2008MATLABMexCompilerFilesX64复制到:C:\Program Files\MATALB\R2007b\bin\win64\mexopts(假设您的版本在默认安装文件夹中为64位).
5. 将文件夹内容VS2008MATLABMBuildCompilerFilesX64复制到:C:\Program Files\MATALB\R2007b\bin\win64\msbuildopts
6. 执行mex -setup，并确认Visual Studio 2008在列表中.

1. Go to https://www.mathworks.com/matlabcentral/fileexchange/18508-microsoft-visual-studio-2008-mex-and-mbuild-setup-files
2. Download the zip file VS2008Matlab.zip (press the "Download zip" blue button on the top right side of the page).
3. Extract the zip file.
4. Copy folder content VS2008MATLABMexCompilerFilesX64 to: C:\Program Files\MATALB\R2007b\bin\win64\mexopts (assuming your version is 64 bit in default installation folder).
5. Copy folder content VS2008MATLABMBuildCompilerFilesX64 to: C:\Program Files\MATALB\R2007b\bin\win64\msbuildopts
6. Execute mex -setup, and verify Visual Studio 2008 is in the list.
