trouble compiling gurobi matlab interface windows 64 bit OS

[phil.m...@gmail.com]

Hello,

I have been using the gurobi MATLAB interface for the past while on a 32 bit windows OS with no problems. However, I have installed it on a 64 bit windows system now and have trouble when I initially try to compile the gurobi interface by running the gurobi_setup.m file.

I get the following error message from matlab:

"    >> gurobi_setup

          Error using gurobi_setup (line 90)

          Invalid MEX-file 'C:\gurobi560\win64\matlab\gurobi.mexw64': The specified module could not be found.

 "

and when I look in the MATLAB folder in Gurobi, it has the gurobi.mexw64 file, so I don't understand why it says the specified module can't be found. I am probably missing some simple step, but any input on this matter would be greatly appreciated.

Cheers,

Phil

Hi Phil,

That error indicates that the dynamic loader could not find the
gurobi56.dll that the gurobi.mexw64 file depends on. The DLL should be
located in C:\gurobi560\win64\bin. The installer updates your PATH
environmental variable to point to this directory. But you may need to
restart for these changes to take affect. If a restart doesn't help,
you may have a corrupt installation. You can try downloading the
installer again and reinstalling Gurobi. An easy way to test that the
install has been successful, is to launch the interactive shell by
clicking on the Gurobi icon on your desktop. If that gives you the
gurobi> prompt, the dll should be in the correct place.

One other thing to watch out for (since you mentioned you are
switching from 32 bit): if you are using 64 bit Gurobi you must use 64
bit MATLAB.
