Problem with gcc compiler with matlab

Hei guys,

I have intalled the ACADO toolkit. I am now trying to install the matlab interface.

My problem is the following : Matlab doesn't seem to find my gcc compiler.

I have installed gcc-4.4 as recommanded for my matlab version (R2013a --> http://www.mathworks.ch/support/comp...ml?sec=glnxa64 ), though I don't see my compiler when typing "mex -setup" in matlab...

Here is the steps to build the interface, and how it should work : http://sourceforge.net/p/acado/wiki/...ing%20Started/

And here is what i get on matlab :

>> mex -setup

Options files control which compiler to use, the compiler and link command
options, and the runtime libraries to link against.

Using the 'mex -setup' command selects an options file that is
placed in /home/raphael/.matlab/R2013a and used by default for 'mex'. An options
file in the current working directory or specified on the command line
overrides the default options file in /home/raphael/.matlab/R2013a.

To override the default options file, use the 'mex -f' command
(see 'mex -help' for more information).

The options files available for mex are:

1: /usr/local/MATLAB/R2013a/bin/mexopts.sh :
Template Options file for building MEX-files


0: Exit with no changes



I don't know if I should install my gcc in a special location... please help if you have an idea!

Thanks

Raphaël
