Error using mex for compiling unravel.c

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).

Please show us the complete output of the mex command.

This is the output of the mex commmand:

C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: Compile of 'unravel.c' failed. 

Error using mex (line 206)
Unable to complete successfully.

Thank you.

Odd. What does

mex -setup

show ?

You got that for

mex -setup

and it did not ask you which compiler to use?

[Image Analyst]

That's strange - on my computer, it says this:

>> 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/R2012b/win64.html 

Please choose your compiler for building MEX-files: 

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

Are you sure it didn't just fail to compile because you have a syntax error?

[Vinh Nguyen]

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

Are these correct [y]/n? y

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

[Vinh Nguyen]

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.

[Vinh Nguyen]

Thank you for your advice. I have used compiled files from my friend and it works for my project.

However, I cannot still compile the C file on my computer.

[Image Analyst]

DO you mean that you compiled files on your computer that your friend gave you and they compiled fine on your computer? But yours don't? I just want to make sure you're not saying that you compiled your files on your friend's computer.

[Vinh Nguyen]

I mean my friend compile the C code for me on his computer and I use it for my project successfully. But I cannot compile on my computer.

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.

[Vinh Nguyen]

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.
