求助：将C文件转换成MEX文件时出错
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！ 原帖由 arlay 于 2006-10-25 22:13 发表

先用mbuild -setup，再用mex -setup，如果没有错误的话，应该可以编译 http://forum.vibunion.com/forum/thread-23070-1-1.html一样的问题 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？ 请高手指点啊，谢谢啦！^_^ http://www.mathworks.com/support/solutions/data/1-1I5TNS.html?product=ML&solution=1-1I5TNS
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。

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 /n? n
Select a compiler:
Borland C++Builder version 6.0
Borland C++Builder version 5.0
Borland C/C++ (free command line tools) version 5.5
Lcc C version 2.4.1
Microsoft Visual C/C++ version 7.1
Microsoft Visual C/C++ version 6.0
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 /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?(/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'.)
Try to update options file: C:\Users\岳青宇\Application Data\MathWorks\MATLAB\R14SP3\compopts.bat

这个是怎么回事啊？mex.c文件始终是失败的。
mex imsmooth.c
