# $Header: /cvsroot/nco/nco/doc/opendap.sh,v 1.14 2009/05/04 22:11:47 zender Exp $
# Purpose: Install OPeNDAP prior to building NCO as DAP-enabled clients
# NB: OPeNDAP/DODS netCDF client library versions 3.4.X are obsolete
# NCO versions > 3.0.1 support OPeNDAP client library versions > 3.5.1
# This file contains up-to-date instructions
# See file dods.sh for supporting older NCO with older DODS libraries
# Terminology:
# Protocol is DAP, its free implementation is OPeNDAP (analogous to SSH/OpenSSH)
# DODS-terminology is being obsoleted in favor of DAP-terminology
# Transition is not complete yet, so hybrid is necessary, e.g., DAP_ROOT
# Testing:
# NCO/SDO server/repositories are accessible via DAP at
# http://esmf.ess.uci.edu/cgi-bin/dods/nph-dods/dodsdata/
# http://soot.ess.uci.edu/cgi-bin/dods/nph-dods/dodsdata/
# http://dust.ess.uci.edu/cgi-bin/dods/nph-dods/dodsdata/
# Physical locations of these repositories is
# soot.ess.uci.edu:/var/www/html/dodsdata
# dust.ess.uci.edu:/var/www/html/dodsdata
# esmf.ess.uci.edu:/data/dodsdata
# WWW of repositories is
# http://dust.ess.uci.edu/dodsdata/
# http://esmf.ess.uci.edu/dodsdata/
# Example DAP-enabled commands:
# ncks -M http://dust.ess.uci.edu/nco in.nc # fails
# ncks -M -p http://dust.ess.uci.edu/nco in.nc # fails
# ncks -M -p http://dust.ess.uci.edu/cgi-bin/dods/nph-dods/dodsdata in.nc
# ncra -O -C -D 3 -p http://dust.ess.uci.edu/cgi-bin/dods/nph-dods/dodsdata in.nc in.nc ~/foo.nc

# Usage:
# Set installation directory below ${DAP_ROOT}
# ~/nco/doc/opendap.sh
# Default invocation retrieves, builds, and installs DAP in ${DATA}/tmp
# ${DATA}/tmp exists on most machines, and equals /tmp when ${DATA} is not defined
cd ${DATA}/tmp
# Remove debris from last DAP install
/bin/rm -r -f DODS* libnc-dap* libdap*

wget ftp://ftp.unidata.ucar.edu/pub/opendap/source/libnc-dap-3.7.0.tar.gz
