[Ipopt] Setting up MATLAB interface in Linux 64 bit

[Gianpaolo Gulletta]

Hi ,

It worked!
The problem was that!

Now when I type "ipopt" on the MATLAB PROMPT I get:

 >> ipopt
Invalid MEX-file '/home/gianpaolo/Ipopt/install/lib/ipopt.mexa64':
/usr/local/MATLAB/R2012b/bin/glnxa64/../../sys/os/glnxa64/libgfortran.so.3: 
version `GFORTRAN_1.4' not found (required by
/home/gianpaolo/Ipopt/install/lib/ipopt.mexa64)

What should I install exactly?

Thank you,

Gianpaolo
