Hi all, I am trying to run mex compiler for unravel.c. However, it always show the error:Error using mex (line 206)Unable to complete successfully.

Although I have try some solution such as download update for Microsoft Visual Studio 2010, the problem keep happening.

Can anyone please help me?

Thank you

PS: I am running MATLAB R2012a and using Microsoft Visual Studio 2010 Express Edition on a 64bit laptop (windows 7).

Sorry. I just show the last part of the setup.

Yes, it did ask me to choose the compiler. Here is the complete report:

mex -setup

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/R2012a/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 Software Development Kit (SDK) 7.1 in C:\Program Files (x86)\Microsoft Visual Studio 10.0

[0] None

Compiler: 1

Please verify your choices:

Compiler: Microsoft Software Development Kit (SDK) 7.1 Location: C:\Program Files (x86)\Microsoft Visual Studio 10.0

Are these correct [y]/n? y

What directory are you in at the time you try to do the compile?

Vinh Nguyen 2012-12-24

A folder inside the C disk. I tried somewhere else. But it still doesn't work.

The free versions of Microsoft products are limited in many ways. For example the "starter edition" of Office won't let you talk to it from MATLAB via ActiveX. A while ago I remember that I encountered some limitation with the Express (free) edition of Visual Studio but I don't remember what it was. Perhaps you're running into something like that. Ask someone who has the full version of Visual Studio to compile it for you, or switch to another compiler.

Your Visual studio Folder is in Program Files (x86), which is often a folder meant for 32 bit applications. Yet you are trying to compile with 64 bit MATLAB because I see win64 in this folder: C:\PROGRA~1\MATLAB\R2012a\bin\win64\. I never try to mix things like that. Are you sure that your version of Visual Studio is a 64 bit app and you're trying to compile in 64 bit MATLAB? Is it possible that the free "Express Edition" of Visual Studio only comes in a 32 bit version? What version of Visual Studio does your friend have - the Professional version or the Enterprise version? Are you sure BOTH you and your friend have the compiler? It's so expensive that usually only one person in an organization has it. Type "ver" on the command line and report what it says back here.

Actually, I firstly installed the SDK 7.1, which seems to be the 32 bit application. When I installed the SDK, I see no option for 64 bit. It does not work for me. Then I find the solution at http://www.mathworks.com/support/solutions/en/data/1-G1P8HP/

May be the problem is the combination of 32 bit SDK and 64 bit Matlab.
