I tried to install FreeFem on Ubuntu 20.04, as recommended on Ubuntu installation.
Everything seems to be ok until I try to run my .edp script, when I get the error
FreeFem++: error while loading shared libraries: libgfortran.so.4: cannot open shared object file: No such file or directory
I found similar error messages on this forum, as well as other sources on the web, e.g. Ubuntu installation issue, and others.
Yet I am unable to solve it.
I have gfortran 11.3.0. It seems that gfortran 7 is needed, but I cannot even find a way to install it as it not on the Linux repositories.
I was hoping there would be some newer version of libgfortran.so.+, to link as in the solution I mentioned before, but I do not know how to find them.
If I issue the command, as suggested by another expert user non this forum
ls: cannot access ‘/usr/lib/libgfortran.so*’: No such file or directory
Any suggestion please? I am really eager to get my scripts up and running again.
