When you build netcdf, it puts certain options on the Fortran based
on the compiler and platform. From a terminal (assuming your
libraries are in /usr/local/lib) do:
nm -a /usr/local/lib/libnetcdff.a | more (this assumes that
both libnetcdff.a and libnetcdf.a were created rather than just the
one library)
then look to see how one of the undefined references in defined in
the library - it probably has some combination of leading or trailing
underscore, and when you compile anything that calls it it must have
the same options set.

You need to be consistent with your fortran compiler and its flags
between compiling netcdf and compiling FVCOM. Did you build the
fortran
part of netcdf? Look through the output of "make check" and configure
to see what it's doing in terms of the fortran. Fortran flags to
watch out for are those involving underscores
(-fno_second_underscore?).
Thank you for your suggestions --
I do not supply any options to gfortran in FVCOM and when compiling
netCDF (the result is also the same with -O2 -g — the only options
given to gfortran in netcdf compile)
I do build fortran netcdf libraries (including f77) (I also built it
separately and shared with same luck)
What else should I look for?
Mikhail.
