Compile yambo-5.0.1

[sitangshu]

Thank you Andrea,

I updated the gcc-Fortran to 8.4.0 and tried make yambo for version 5.0.2. However, at the initial libxc stage it got stuck:

Hi there,

I think this is a problem of the installation. Is gfortran pointing to the right executable ?
do you have two versions of the gcc software stack ?

Hi Andrea,

Thanks! I got the fix, seems to be working with a less gcc version.
