求助：将C文件转换成MEX文件时出错

arlay

在执行MEX filename.c时，系统提示：

  Could not find the compiler "cl" on the DOS path.
  Use mex -setup to configure your environment properly.

   C:\PROGRAM FILES\MATLAB704\BIN\WIN32\MEX.PL: Error: Unable to locate compiler.

请问这是什么原因啊？“cl“是什么compiler啊？在这之前我已经mex -setup过了，选的是Microsoft Visual c/c++ 6.0编译器。是因为这个编译器不在MATLAB下吗？当我用Lcc编译器的时候就没问题。请高手指点，谢谢！

先用mbuild -setup，再用mex -setup，如果没有错误的话，应该可以编译

1、mbuild -setup,选了msvc6.0编译器；
2、mcc -m filenames, 出错：
     Could not find the compiler "cl" on the DOS path.
  Use mbuild -setup to configure your environment properly.


  C:\PROGRAM FILES\MATLAB704\BIN\WIN32\\..\WIN32\MEX.PL: Error: Unable to locate compiler.

3、把msvc60engmatopts.bat中的
      rem************************
      rem General parameters
      rem************************
      set MATLAB=%MATLAB%
      set MSVCDir=%MSVCDir%
      set MSDevDir=%MSVCDir%\..\Common\msdev98
      set PATH=%MAVCDir%\BIN;%MSDevDir%\bin;%PATH%

      改为：

      rem************************
      rem General parameters
      rem************************
      set MATLAB=%MATLAB%
      set MSVCDir=C：Program files\Micro...\VC98
      set MSDevDir=%MSVCDir%\..\Common\msdev98
      set PATH=%MAVCDir%\BIN;%MSDevDir%\bin;%PATH%

      再mcc还是出错，出错提示跟上面一样，是什么原因阿？

Subject:
Why do I get an error message regarding the "cl" compiler on the DOS path when compiling and linking engine programs in MATLAB 7.0.4 (R14SP2)?

Problem Description:
When I compile and link MATLAB Engine programs, MATLAB cannot find the compiler.
For example, type the following at the MATLAB command prompt:

optsFile = fullfile(matlabroot,'bin','win32','mexopts','msvc71engmatopts.bat');
compFile = fullfile(matlabroot,'extern','examples','eng_mat','engwindemo.c');
mex(compFile,'-f',optsFile)

The following error message occurs:
Could not find the compiler "cl" on the DOS path.
Use mex -setup to configure your environment properly.

D:\APPLICATIONS\MATLAB704\BIN\WIN32\MEX.PL: Error: Unable to locate compiler.

??? Error using ==> mex
Unable to complete successfully


Solution:
To solve the issue, set MSVCDir to the ACTUAL location of your MSVC install, for
example:
Make a copy of the "msvc71engmatopts.bat" file in the current working directory. Open and edit the file. In line 13, change the "MSVCDir" variable from:


set MSVCDir=%MSVCDir%
to:

set MSVCDir=C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7
(where C:\Program Files is the directory that contains Microsoft Visual Studio .NET 2003)

thanks a lot! ^_^

我选用的是msvc60编译器，把msvc60engmatopts.bat文件拷到当前工作目录下，然后将其中的13行
set MSVCDir=%MSVCDir%
改为
set MSVCDir=C:\Program Files\MATLAB704\extern\lib\win32\microsoft\msvc60
出错：
Could not find the compiler "cl" on the DOS path.
  Use mbuild -setup to configure your environment properly.


  C:\PROGRAM FILES\MATLAB704\BIN\WIN32\\..\WIN32\MEX.PL: Error: Unable to locate compiler

又改为：
set MSVCDir=C:\Program Files\MathWorks\MATLAB Component Runtime\v72\extern\lib\win32\microsoft\msvc60

但是依然出现同样的错误。

请问各位高手，这到底是什么原因阿？是我的MSVCDir找得不对吗？我是直接搜索的msvc60，搜到两个文件夹分别位于上面两个路径下，然后直接把路径拷贝过去的。

谢谢啦！

MSVCDir显然不对，msvc60你装哪儿上哪儿找去

Please choose your compiler for building standalone MATLAB applications:

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

Select a compiler:
[1] Borland C++Builder version 6.0
[2] Borland C++Builder version 5.0
[3] Borland C/C++ (free command line tools) version 5.5
[4] Lcc C version 2.4.1
[5] Microsoft Visual C/C++ version 7.1
[6] Microsoft Visual C/C++ version 6.0

[0] None

Compiler: 5

The default location for Microsoft Visual C/C++ compilers is C:\Program Files\Microsoft Visual Studio .NET 2003,
but that directory does not exist on this machine.  

Use C:\Program Files\Microsoft Visual Studio .NET 2003 anyway [y]/n? y

Please verify your choices:

Compiler: Microsoft Visual C/C++ 7.1
Location: C:\Program Files\Microsoft Visual Studio .NET 2003

Are these correct?([y]/n): y
Warning: Mbuild requires that the Microsoft Visual C++ 7.0
directories "Vc7" and "Common7" be located within the same parent directory.
(Expected to find a directory named "Common7" in the directory 'C:\Program Files\Microsoft Visual Studio .NET 2003'.)

这个是怎么回事啊？mex  .c文件始终是失败的。

mex imsmooth.c
  Could not find the compiler "cl" on the DOS path.
  Use mex -setup to configure your environment properly.
