Try looking in config.log for the full error from the linker. It
could be a 32/64 bit mismatch between the C and gfortran defaults.
Sounds like FVCOM definitely needs the fortran interface module
(netcdf.mod).

Hi,
I'm having trouble installing/using NetCDF, and having looked at the
website I hope I've picked the right mailing list. Sorry if I'm
sending this in error.
I have a macbook pro and I'm new to compiling. I am trying to
install NetCDF to use with a modelling program called FVCOM, which I
also have to compile. I had compiled fvcom fine but then realised I
needed NetCDF libraries installed. On my first attempt to install
NetCDF, 'configure' produced this error:
checking if Fortran "byte" is C "signed char"...
configure: error: Could not link conftestf.o and conftest.o
and after searching online found that they suggested using this
line of code instead, if you didn't need fortran installed.
FC= ./configure
as I have already got gfortran installed I thought that would be ok.
It seemed to work, as after this was typed it compiled and installed
fine. However, when I tried to compile FVCOM while linking to these
libraries, it came up with this error:
Can't open module file 'netcdf.mod' for reading at (1): No such file
or directory
And there is indeed no netcdf.mod file in the 'include' directory.
I'm not sure where to go from here... as it seems to be a NetCDF
issue at this point I thought here was the best place. I read in an
archive something about telling NetCDF about the existing gfortran
libraries when it configures - but I have no idea how to do that.
Does anybody know how I fix this?
Many thanks,
Jenny
