用mcc将m文件生成dll时提示无法找到cl编译器

jainibunan

用的matlab6.5.
我现在想在vc中调用m文件中的函数，因此想将m文件生成dll，为了充分说明问题，我把前面编译器配置过程也说一下。
mex -setup
Please choose your compiler for building external interface (MEX) files:

Would you like mex to locate installed compilers [y]/n? n
.....
mbuild -setup
Please choose your compiler for building standalone MATLAB applications:

Would you like mbuild to locate installed compilers [y]/n? n
....
两个命令后面都出现了类似的警告，如下：
Warning: Mbuild requires that the Microsoft Visual C++ 6.0
directories "VC98" and "Common" be located within the same parent directory.
(Expected to find a directory named "Common" in the directory 'e:\program files'.)
The default options file:

上面我选择的是vc6.0.
我没有理会，然后我用 mcc -t -h -L C -W lib:ppp -T link:lib myfunct.m（也是摘抄自网上的），出现了下面的提示：
Could not find the compiler "cl" on the DOS path.
  Use mbuild -setup to configure your environment properly.  

  MBUILD.BAT: Error: Unable to locate compiler.

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

??? Error: An error occurred while shelling out to mbuild (error code = 1).
Unable to build executable (specify the -v option for more information).

Error in ==> E:\MATLAB6p5\toolbox\compiler\mcc.dll

请问这是怎么回事呢？请指点一下！（但却生成了.h 和.c文件）
焦急等待中！

自己补充一下，我已按照网上资料将msvc70engmatopts.bat文件copy到work当前工作目录，并将MSVCDir改为编译器cl所在目录E:\Program Files\Bin。

嗨，一直都没人来解答，好伤心哦！
不过我自己把问题解决了，先把方法说出来，以便后来人碰到同样的问题可用。
其实问题的关键在上面提示里的那句警告：
Warning: Mbuild requires that the Microsoft Visual C++ 6.0
directories "VC98" and "Common" be located within the same parent directory.
(Expected to find a directory named "Common" in the directory 'e:\program files'.)
然后我仔细一看我的vc安装目录，不知怎搞的居然发现没有vc98目录，真是笑死人了，天天用vc竟然没发现这个问题。（我是编译器装在e盘，而可执行程序和其它公共库在c盘的）所以我就把vc卸载了，重新装了一遍（一切都装在同个目录）。一切ok，然后再mex和mbuild就一切顺利了。
所以总结是：matlab找不到编译器可能与你的vc6.0安装方式有关系。
