Hi,
I would like help to install Gurobi Mex for use in Matlab R2009a (v.
7.8.0.347, 64-bit) on a Win 7 (64-bit) computer. I have followed the
instructions on http://www.convexoptimization.com/wikimization/index.php/Gurobi_Mex:_A_MATLAB_interface_for_Gurobi.
The issue surfaces when I attempt to install a compiler. I downloaded
and installed Microsoft Visual C++ 2008 Express and SDK 7.1 with
default options. Once this has been completed I am stuck, as follows:
>> mex -setup
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] Microsoft Visual C++ 2008 Express in C:\Program Files
(x86)\Microsoft Visual Studio 9.0
[0] None
Compiler: 1
Please verify your choices:
Compiler: Microsoft Visual C++ 2008 Express
Location: C:\Program Files (x86)\Microsoft Visual Studio 9.0
Are these correct [y]/n? y
*****************************************************************************
Error: Could not find the 64-bit compiler. This may indicate that
the
"X64 Compilers and Tools" or the Microsoft Windows Software
Development Kit (SDK) is not installed. To build 64-bit MEX-
files
Microsoft Visual C++ 2008 Express Edition requires that these
two
packages are installed properly.
*****************************************************************************
I have checked that the option X64 compiler is highlighted.

The error is because VC Express does not include a 64-bit compiler,
just a 32-bit one.
just a 32-bit one.
You can install the latest version Windows platform SDK, free of
charge, and check the options: compilers and x64 libraries. Then after
a system reboot, you will see a second option in "mex -setup" with
64-bit compiling.
Also I can send you a precompiled mex for 64-bit Windows.

I uploaded a mexw64 file at http://bit.ly/wLKtcl. It was compiled with
Win 7 64-bit, Matlab 2011b, Gurobi 4.6.1, and Gurobi Mex 1.61.

Hi Wotao,
When I installed Windows SDK 7.1 (http://www.microsoft.com/download/en/
details.aspx?id=8279) I selected all options including the one called
"Visual C++ Compilers" with the following description: "Visual C++
Compilers Installs the Visual Studio 2010 Visual C++ Compilers.
Includes x86, x64, and Itanium compilers for C Runtime (CRT)." and the
unit has been rebooted, but still I obtain the same response to mex -
setup. I would appreciate very much if you could please send me the
precompiled mex for 64-bit Windows as you suggested, any other
suggestions are also welcomed.
Thanks for your help, Patrik

Patrik,
That's strange. In Matlab R2010b, "mex -setup" gives two options.
[1] Microsoft Software Development Kit (SDK) 7.1 in C:\Program Files
(x86)\Microsoft Visual Studio 10.0
[2] Microsoft Visual C++ 2010 Express in C:\Program Files
(x86)\Microsoft Visual Studio 10.0
and option [1] works fine for 64-bit compiling.
Perhaps R2009a does not support the latest SDKs.
I uploaded a mexw64 file at http://bit.ly/wLKtcl.

Dear Wotao,
Thanks for your support. I downloaded the mexw64 file and saved it in
the same folder where gurobi_mex.c was kept (i.e. the folder
downloaded from SourceForge for gurobi_mex_v1.61. I then started
Matlab and added this folder (gurobi_mex_v1.61) to the path and
thereafter following the instructions on the convexoptimization site
tried the command 'compile_mex', with the following results:
----------------------
\MathWorks\MATLAB\R2009a\mexopts.bat
From template: C:\PROGRA~1\MATLAB\R2009a\bin\win64\mexopts

Before that, I also tried without first running mex -setup, identical
results.
I also thereafter tried with or without setting the path to c:
\gurobi461 (where gurobi itself is located) and to also run the
following command: 'gurobi_mex' with the following results with or
without gurobi461 on the path:
----------------

Check input & ouput.

Any suggestions would be appreciated, I am a wet-lab biologist so it
is not straightforward to sort it out. If the version of Matlab is the
problem, I will need more time to fix it as our service contract has
run out so we don't receive updates any longer.

Dear Patrik,
I am inclined to believe that your Matlab does not support latest MSVC Express or platform SDK.

Thanks Wotao, I will obtain the updated Matlab and then try again, and
let you know how it went. It will take time though, delayed by
administration etc..

Hi Wotao,
I'm a beginner, so forgive me if the question is trivial, but I have successfully followed instructions for installing Gurobi Mex in MATLAB through step 3, but when I run compile_mex
I get the following error:
Error using +
Matrix dimensions must agree.
Error in compile_mex (line 40)
grb_ver = gurobi_addr([6 7]+pos);
I am using Windows, with a 32-bit Matlab. I am wondering if the error message has something to do with the following message: "The MATLAB C and Fortran API has changed to support MATLAB variables with more than 2^32-1 elements. In the near future you will be required to update your code to utilize the new API. You can find more information about this at: http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html Building with the -largeArrayDims option enables the new API."
I really appreciate the help!

Hi Everyone!
I am having trouble getting gurobi_mex to work with older versions of gurobi specifically v5.0.2. Because you cannot directly install a license for this version you have to first install v6.03 and then download the license for this version and then install a lower version of gurobi (again in my case v5.0.2) However when I try and run gurobi_mex with the v5.0.2 I get the following error:
Error using gurobi_mex
Error: could not create environment. Please make sure that GUROBI has a license and been validated.
Does anyone have any ideas on how to fix this.
Thanks for any help!

Hi,
I'm getting the same error as Serina Lee Robinson. I've installed Gurobi v6.0.4 and trying to install gurobi mex v1.61.
@Serina, if your error is resolved please let me know how to go about it.
Thanks a lot in advance,

Hello,
I am getting the following error..
Invalid MEX-file 'C:\Program Files\MATLAB\R2016a\toolbox\gurobi652\win64\matlab\gurobi.mexw64': The specified
module could not be found.
Error in solveCobraLP (line 973)
resultgurobi = gurobi(LPproblem,param);
Error in optimizeCbModel (line 213)
solution = solveCobraLP(LPproblem);
The gurobi folder already contains the gurobi.mexw64, but I don't know what went wrong?
Can anybody help me out? Thanks in Advance,
Narendran
