To do anything with DODS, you'll need to be able to unpack the archive
files you can download from the OPeNDAP site. To save space and
transmission time, the archive files are compressed with the
gzip program. You will have to have a copy of that program to
unpack the OPeNDAP software.
Most of the software you need for OPeNDAP is avaliable from the GNU archives. Refer to http://www.gnu.org for instructions. Look at http://www.gnu.org/order/ftp.html for a list of mirrors of that archive. Use the mirror closest to you, the transmission will be faster.
Follow the instructions to install each of the following software
packages. Typically, you would install a package called foo as
follows:
gzip -dc foo.tar.gz | tar xvf - cd foo ./configure make make install
This is simply a guide, of course, and the installation instructions for each software package should be followed carefully.
