Hi I have just upgraded to Ubuntu 13.04 and afterwards I found out that it comes with GCC 4.7.3. When I try to compile mex files, I get the following error:

You are using gcc version "4.7.3". The version currently supported with MEX is "4.4.x"

Can anyone suggest any work around for this?

I am using MATLAB 2013a on 64 bit Ubuntu.

I have tried to install previous versions of GCC: apt-get install gcc-4.4 But it cannot locate it.

Best Regards Wajahat

Hi, Just checking if the problem has been resolved.

I am getting similar error on Ubuntu 13.04 x86_64-linux-gnu when trying to set up package SBPOP.

I have installed gcc 4.4 and gcc 4.4.7

I get no options with:

~$ sudo update-alternatives --config gcc
update-alternatives: error: no alternatives for gcc

will be listening for a solution aswell

You probably need to add some repositories if apt can't locate gcc-4.4. I'm sure if you run a google search or look around the Ubuntu forums there will be a howto or a question already asked about how to get an earlier version of gcc installed.
