Problem with mex -setup

This is the error message I get when running mex -setup:

??? Error using ==> mex at 208 Unable to complete successfully.

I have seen other people have problems at the same line, but they get other error messages explaining why it fails, but I just get this.

I am using R2011a x64 and have tried both VC++ 2010 Express with Microsoft SDK 7.1, and VC++ 2010 Professional, as per: http://www.mathworks.co.uk/support/compilers/R2011a/win64.html

I have tried automatically detecting compatible compilers and specifying the path manually with the same result.

I have tried uninstalling everything and reinstalling them as explained here: http://www.mathworks.com/matlabcentral/answers/96611 ...and I still get the same error.

I am running Windows 8.1 x64. The files that I am trying to compile with mex I am able to compile on Linux with no problems, but I need to be able to work on Windows.

Any help would be greatly appreciated :)

The full output from the mex -setup command is:

Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2011a/win64.html

Please choose your compiler for building MEX-files:

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

Select a compiler:

[1] Microsoft Visual C++ 2010 in c:\Program Files (x86)\Microsoft Visual Studio 10.0

[0] None

Compiler: 1

Please verify your choices:

Compiler: Microsoft Visual C++ 2010

Location: c:\Program Files (x86)\Microsoft Visual Studio 10.0

Are these correct [y]/n? y

Warning: MEX-files generated using Microsoft Visual C++ 2010 require

         If you plan to redistribute your MEX-files to other MATLAB 
         users, be sure that they have the run-time libraries.

R2011a is not supported on Win8. So one never knows what can go wrong here. But basically ML detects the compiler and also updates the mexopts.bat file. So that looks good.

Can you try to compile a skelleton mex file (so only the minimum of code you need for a MEX) and see what happens? Compile with -v flag to get some verbose output.

[Dan]

Ah okay. I might try a later version of matlab then.

I'm new to mex so I'm not really sure what you mean by a skeleton mex file, but even running mex -h for help gives the same error.

Thanks for the reply!

[Friedrich]

with skelleton i mean

#include "mex.h"

void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{

}

Assuming that code above is the content of test.c call mex like this

mex test.c -v

Have now downloaded R2013a and it seems to work, very strange but thanks for your help!

For the record, running this skeleton gave the same error as before.
