mex -setup error

Hi,

I am trying to setup mex on my machine, and I get the following error:



>> mex -setup
The system cannot find the path specified.
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 C version 2.4.1 in C:\PROGRA~1\MATLAB\R2006b\sys\lcc
[2] Microsoft Visual C/C++ version 7.1 in C:\Program Files\Microsoft Visual Studio .NET 2003
[3] Microsoft Visual C/C++ version 6.0 in C:\Program Files\Microsoft Visual Studio
[4] Open WATCOM C/C++ version 1.3 in C:\watcom-1.3
 
[0] None
 
Compiler: 2
 
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
 
Trying to update options file: C:\Documents and Settings\Ajay\Application Data\MathWorks\MATLAB\R2006b\mexopts.bat
From template: C:\PROGRA~1\MATLAB\R2006b\bin\win32\mexopts\msvc71opts.bat
 
Done . . .
 
??? Error using ==> mex
Unable to complete successfully.


Anyone knows what could be the problem?

Thanks,
Ajay

Matlab uses a complete -bat-File to adjust pathes and options of the compiler. All of the possible files are in one folder. It looks like one of these preset pathes or options may wrong. I would suggest to check each bat-line if they all locate to valid files.

Hi Roland,

I tried checking the bat file ( under "C:\Documents and Settings\Ajay\Application Data\MathWorks\MATLAB\R2006b"). If I try to open it (right click -> edit) I get a message "The filename, directory name, or volume label syntax is incorrect". And I just found out I cannot open any .bat file on my machine, it gives me the same error (as far as I remember it was not the case before). I have also tried uninstalling the matlab and do a fresh install, so must be something else that is messing up the .bat files. Thanks for your suggestion.

Ajay

Dear Ajay
 I too have a similar problem.I understand that after writing a C mex S function, only if we compile with the mex command will simulink identify the file,is it not? When i tried to enter the Sfunction name in the s function block of simulink and attempted simulation, the error that the such a file does not exist popped up.
I too tried to give the 'mex filename' command at the matlab command line to generate the executable...and am getting the same error as yours

"C:\MATLAB701\BIN\WIN32\MEX.PL: Error: 'filename.c' not found.
???Error using ==> mex
> Unable to complete successfully."

if u have been able to solve your problem by now, could you please help me.

Thank You
Sangeetha
