The symbol"utopen_" wasn't resolved during the link phase because the
UDUNITS library wasn't referenced in the f77(1) command-line. Try a
command like
f77 -o readgeneral readgeneral.f -L /usr/user6/shie/dir-t2m/local/lib -l
udunits
> (2) install.log
Looked OK.
> (3) make.log
Looked OK.
> (4) README: The commands I did (per your instruction) for installing
> udunits-1.12.9, and what it has produced
Looked OK.
