Hello,
I'm trying to learn about MEX files for a project where I will have to interface between a fortran code and matlab code.I wanted to start out with the examples for mathworks but can't get past the mex -setup. Please see the following:
>> 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/R2011b/win64.html
Please choose your compiler for building MEX-files:
Would you like mex to locate installed compilers [y]/n? n
Select a compiler:
[1] Intel C++ 12.0 (with Microsoft Visual C++ 2008 SP1 linker)
[2] Intel C++ 12.0 (with Microsoft Visual C++ 2010 linker)

Warning: The default location for Intel Visual Fortran compiler is:
"C:\Program Files (x86)\Intel\Compiler\11.1\054\"
but either that directory does not exist or the configuration
is invalid.
Use C:\Program Files (x86)\Intel\Compiler\11.1\054\ anyway [y]/n? n
Please enter the location of your compiler: [C:\Program Files (x86)\Intel\Compiler\11.1\054\] [C:\Program Files (x86)\Intel\Compiler\11.1\038\]
Please verify your choices:
Compiler: Intel Visual Fortran 11.1
Location: [C:\Program Files (x86)\Intel\Compiler\11.1\038\]
Are these correct [y]/n? y

Warning: Support for Intel Visual Fortran 11.1 will be discontinued in a

Error: Microsoft Visual Studio 2008 SP1 Professional Edition was
not found by mex -setup.
The Microsoft Visual Studio 2008 SP1 Professional Edition
linker is required to build Intel Fortran MEX-files. Please
make sure that Microsoft Visual Studio 2008 SP1 Professional
Edition is installed properly.
Error using mex (line 206)

I have intel fortran 11.1 compiler and mvs 2008shell. Any help so I can successfully link to the write compiler?

MEX is not able to find the 64-bit Visual C++ 2008 tools. I would recommend:
  1. First confirm that 64-bit Visual Studio 2008 and/or SDK 6.1 tools are installed. This version of Visual Studio may not have installed the 64-bit tools.
  2. Ensure that you can compile a simple 64-bit C program from the Visual Studio IDE and command line (the later using VCVARSALL -- you should have a Start Menu item for this)
  3. Only then try to bring the Intel compiler into the mix
If this sounds too painful, installing .NET 4.0 and then the (free) Microsoft Windows SDK 7.1 should give you the 64-bit tools you need.

To make sure the SDK environment variables gets set, I would log out and log back in (or, better yet, reboot). Then:
In Windows's Start Menu, are you able to open "All Programs" -> "Microsoft Windows SDK v7.1" -> "Windows SDK 7.1 Command Prompt" without error? You should get a Command Windows with the following message (colored yellow):
"Setting SDK environment relative to C:\Program Files\Microsoft SDKs\Windows\v7.1\.
Targeting Windows 7 x64 Debug"
If this work, type "SET" in the Command Window. Among the output should be:
VS100COMNTOOLS=c:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools\
Do you see all of this?

Hi Ken,
Yes I see this. Mathlab is now reading the compiler:

Try answering "y", when the setup is asking "Would you like mex to locate installed compilers". What does appear?

Yes, I believe so. The info states "Microsoft Visual Studio 2008 Versions 9.0.30729.1 SP".

@hojjat: 1. There are no error messages, but these are standard warning. Read them, add the required MSVC2010 redistributables when you share the compiled functions with others, use -largeArrayDims to apply 64 bit addressing. Then forget these messages.
2. Do not append a new question to an existing thread. Such thread-highjacking confuses the readers, because it will not be clear, to which question answer belong to. In addition you cannot accept an answer in a foreign thread.
3. As consequence from 1. and 2. I suggest to delete this "answer", because it is none and the question can be answered by "that's ok".

I too faced similar problem
Finally I just uninstalled all the C++2010, C++2008 and C++2005. Then Installed the 7.1 SDK , by unchecking its c++ compiler and the visual studio while installing.
Then i could still see the C++2010 (64 and 86 one), in my control panel installed program list.
I gone ahead with installing the patch.
Then the problem got solved..
Note: While u start ur matlab.. the required c++2005 and c++2008 will get installed automatically.. so no need to worry if u get a command window.
