The best place to ask questions or report bugs is
address@hidden.  That way they will get routed to someone
who is here to answer them, even if I happen to be away from my email.

I assume you mean netCDF version 3.5.0.

The nf90_strerror(ncerr) function is defined in the source file
netcdf/src/f90/netcdf_file.f90, so it should be in libnetcdf.a if that
library was correctly built and installed from the 3.5.0 sources and
if the configure script found a working Fortran 90 compiler.  As part
of installing netCDF, when you run "make test" it compiles, links, and
runs a Fortran90 test program in src/f90:

 Making `test' in directory /scratch/russ/builds/buddy0/src/f90

 /opt/SUNWspro/bin/f90 -o netcdf_test   netcdf_test.f90 netcdf.o typeSizes.o 
../libsrc/libnetcdf.a 
 *** Success ***

and that test program (src/f90/netcdf_test.f90) calls nf90_strerror
several times, so it could not have run if nf90_strerror were not in
the library.

Maybe you are trying to link to a library from a previous version of
netCDF before 3.5.0 (the first released version that included the
Fortran90 interface), or perhaps the library needs to be rebuilt since
a Fortran90 compiler was installed.  For instructions on rebuilding
the library from source, see
