Libgfortran5 for ccx2.21

[Fabrice]

Hello,

I have the same issue. I could not find a solution…

CCX 2.20 not work on my Xubuntu 22.04 installation

thank you @jlucas, but I am not comfortable with compiling CCX. I will keep it as a last resort. I found an old CCX 2.17 in Ubuntu repo and installed it. It does not solve the library issue for CCX 2.20 but it does run without error. A mystery to me…
