20040310: building netCDF on 64-bit AMD Opteron

Bernard,

I just successfully built and tested version 3.5.1 of the netCDF package
on our Linux Opteron system:

    $ uname -a
    Linux oliver.unidata.ucar.edu 2.4.22-1.2135.nptlsmp #1 SMP Mon Dec 15 
15:45:38 EST 2003 x86_64 x86_64 x86_64 GNU/Linux

I used gcc(1) and g77(1):

    $ /usr/bin/gcc --version
    gcc (GCC) 3.3.2 20031022 (Red Hat Linux 3.3.2-1)
    ...
    $ /usr/bin/f77 --version
    GNU Fortran (GCC) 3.3.2 20031022 (Red Hat Linux 3.3.2-1)
    ...

and the following configuration command:

   CC=/usr/bin/gcc CPPFLAGS='-DNDEBUG -Df2cFortran' CFLAGS='-O -m64' 
FC=/usr/bin/g77 FFLAGS='-O -Wno-globals' CXX= ./configure

Please investigate how your attempt or buld-environment differs from
mine.

Also, the output from your "make":

> Making `all' in directory 
> /home/priv/legras/install-mdk92-amd64/src/netcdf-3.5.1/src/fortran
> 
> make[2]: Entering directory 
> `/home/priv/legras/install-mdk92-amd64/src/netcdf-3.5.1/src/fortran'
> ar cru ../libsrc/libnetcdf.a fort-attio.o fort-control.o fort-dim.o 

doesn't have compilation commands before the ar(1) command.  Did you
need to execute the command "make distclean" and re-execute the
"configure" script before attempting the build?

Regards,
Steve Emmerson
