I have just tried building netCDF-3.4 on a linux_2.2-i686 (RedHat 7.0)
platform, setting the following environment variables before running
the "configure" script:

 CC=egcs
 CPPFLAGS="-DNDEBUG -Df2cFortran"
 CFLAGS=-O
 FC=f77
 FFLAGS="-O -Wno-globals"
 CXX=/usr/bin/g++

and everything worked fine, with no error messages.

Our netCDF software doesn't reference the g2c library (-lg2c), so it
looks like this is referenced by f77 (/usr/bin/g77) on your system.

Could you test this by trying to compile, link, and run a trivial
Fortran program, such as the following 2-line program, which you could
put in a file named "hello.f":
        print *, "hello world"
        end
Then try to compile, link, and run it with
  f77 -o hello hello.f; ./hello

If you get a message about "cannot open -lg2c: ...", we will know it
is your f77 installation that needs to be fixed.  You can build
netCDF-3.4 without a Fortran interface by just setting the
environment variable FC to "" before you run the configure script (rm
config.cache first also), if you just need the C or C++ interfaces.

Alternatively, you could try the latest netcdf-3.5 beta release, which
we have also tested on a Linux 2.2 platform with 77.  It is available
from
