John-


I've been meeting with managers from our group and the EPA and it sounds
like they're interested in having me get to know the "source code" of
IDV so that I could tailor it to accommodate "ioapi", "m3io", and other
types of netcdf files... However, what I'd like to find out is if you
(or your group) would rather prefer making alterations in the source
code to accommodate the various files that EPA wants to have done or
send the source code to us and have us work on it....  I know that the
EPA would like to have this capability and what I'm doing is sharing
with you this information and finding out what your thoughts (and/or
direction) are on this....


The IDV source is freely available under the terms of the
Lesser GNU Public License (LGPL) to the EPA (or anyone
else) for use as they see fit under those guidelines.  I've
attached a document that details how to download the source
and set up the environment (it's not on line).

If you fix bugs and/or make modifications that would be
generally useful, we would consider rolling them back into
the code.  Since the EPA falls outside the UPC's support area,
the best we can offer is to help you make modifications as
time permits.
Thanks, Don, and have a very fine day, 

Thanks.  Have a good weekend.

Don

Title: Downloading and Running the Unidata IDV
Back to Table of Contents

Building the IDV from source.

$Date: 2003/04/17 19:40:12 $

Before building the IDV you need to first install Ant (http://ant.apache.org/) on your machine. Ant is similar to make - instead of a Makefile Ant uses a build.xml file (found in ucar/build.xml).

Next, download the MetApps source files from the Unidata Web Site (under Downloads->IDV->Source):

unJAR this file using "jar xvf metapps_src.jar". This will create a "metapps" directory underneath the install directory (where you unJAR'ed the file).

You should then create a lib directory as a peer of the "ucar" directory under "metapps" that holds the ancillary jar files from the IDV distribution that are needed to build the classes. The structure will look like this:

metapps
     |
     +----ucar
     |
     +----lib (holds the ancillary jar files).

Download the ancillary JAR files, idv_jars.zip, from the Downloads -> IDV -> Binary section of the Unidata Web site:

to the lib directory and unzip the file.

Now you should be able to cd to the ucar directory and run ant with the idvjar target:

    ant idvjar

This does a clean (removing all .class files), makes the IDV and creates the idv.jar file, copying it to the lib directory.

To run the IDV you can cd to the lib directory and run:

    java -Xmx512m -jar idv.jar

To simply clean the source tree do:

    ant clean

If you are doing development work within the ucar packages you can add the <install_dir> to your classpath and use the 'ant idv' target to compile the IDV source:

    ant idv

If you are compiling directly with javac you need to add the 'metapps' and all of the jar files in the lib dir (except the idv.jar) to your classpath.
