Hello,
I have installed NCEPLIBS in a CentOS8 (AArch64) system and was trying to compile UPP when the linker produced the following error:
[ 86%] Linking Fortran executable ncep_post

It's unclear (to me) whether the origin of the error is because the system is AArch64 architecture or the installation of UPP or NCEPLIBS. I guess that netcdf-fortran could also be but it's installed from source and hasn't caused any issue with other apps that are running fine. Thanks.
