Install a previous version of gcc for Matlab in Ubuntu 18.04

Raw

Using the information from the answer in this link: We install the gcc-5.5.0 instead of 6.3.0 because of the fix mentioned here The fix was backported to gcc-6-branch in r249957 and to gcc-5-branch in r249958. So it's included in gcc-5.5.0 and will be included in gcc-6.5.0

tar xvzf gcc-5.5.0.tar.gz
cd gcc-5.5.0/
./contrib/download_prerequisites
cd ~
mkdir gcc-build && cd gcc-build
/path/to/the/extracted/folder/gcc-5.5.0/configure -v --prefix=$HOME/gcc-5.5.0 --disable-multilib
