[netCDF #LKB-522731]: netcdf4 isntall

Edin,

The netCDF-4 software requires zlib, and szip cannot be used as a substitute
for it.

The configure script is specific to each software package, and different
configure scripts do not
necessarily take the same options.  You can determine which options are legal
for zlib by
running

  ./configure --help

from the zlib source distribution.  This will tell you that it only accepts a
small number of options
and CFLAGS is not one of them.  However, you can set the environment variable
CFLAGS to "-m64"
before running the configure script and it should work.  The comments at the
top of the zlib
configure script also include these instructions:

# To impose specific compiler or flags or install directory, use for example:
#    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
# or for csh/tcsh users:
#    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)

So depending on which kind of shell you are using, you should be able to just
do something like

  $ export CFLAGS=-m64
  $ export CC=gcc
  $ ./configure --prefix=/usr/local
  $ make test
  $ make install

or using setenv for csh or tcsh shell.  The configure script that comes with
the zlib software is
sort of old-fashioned, and evidently it was created manually rather than
generated with the
same tool used for HDF5 and netCDF-4.  So you have to be adaptable and use
whatever
instructions come with each package to install it.  They may look the same, but
the build scripts
typically have different options and conventions.  The comments in the zlib
Makefile even say
that the default installation is in /usr/local, so you actually don't need the
--prefix=/usr/local
option to the configure script.
