Until last year, I was able to run CCX programs provided by Guido Dhondt with Xubuntu 18.04 and 20.4. For 22.04, I cannot make it run since a Fortran library is missing:
I cannot find in Ubuntu repository the proper package for this library. I try to install
gfortran packages hoping that this library would be provided along but I have still the same issue.
Does someone have this issue on Ubuntu ?
The required package is “libgfortran4”. It may be possible to install even if not part of the standard setup.
I found a package for a previous version of Ubuntu (focal) at UbuntuUpdates - Package "libgfortran4" (focal 20.04) →
But I cannot install the package with
dpkg: it seems it is not a debian archive…
You can always compile the program. Ive already posted a makefile and instructions which would probably work (this is with spooles only…)
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…
