Introduction




This document describes the structure and contents of the latest version of the NAIF icy Toolkit for PC computers using LINUX operating system.

Most C compilers come with a large set of compilation options that can be used when compiling source code. The compiler options we (NAIF) used when creating the various object libraries are discussed in the section "LIB" that appears later in this document.

Directory Structure and Contents




The top level directory, icy, contains the file makeall.csh. This is a script that builds all of the object libraries and executables in the icy Toolkit.

ICY



ICY is an interface to the CSPICE library from Interactive Data Language (IDL). This interface uses the IDL dynamic linked module (DLM) functionality to provide an IDL programmer/user access to selected CSPICE routines from within the IDL environment.

This directory contains the ICY source code and a script to create the ICY shared object library.

ICYCOOK



The ICY cookbooks are sample IDL modules that demonstrate how to use ICY functions to obtain state vectors, convert between different time representations, and solve simple geometry problems.

This directory contains the ICYCOOK IDL modules.

Using the Toolkit






Top

All Users



After completing your Toolkit installation it is extremely important that you carefully read the ``whats.new'' description of changes and additions if you haven't done so prior to the installation.

The Toolkit contains two styles of documentation: a plain text version and a hyper-linked HTML version. NAIF recommends you use the HTML version because of the convenience of the hyper-linking. To do that load the top level index of the HTML documentation -- ``doc/html/index.html'' -- into a web browser.

Repeat Users



If you are not a first time user, save your own application executables in a safe place and then re-link those application programs to the newly installed library, creating new executables. NAIF suggests you carefully re-test any critical applications to be sure they are working correctly -- you may have unknowingly taken advantage of a bug in the old library that has since been fixed.

Be aware that sometimes a bug fix or a small algorithmic change in the new SPICE code could result in small changes in numeric results; this could show up in your regression test cases.

First Time Users



NAIF provides several means to help you get started using SPICE -- tutorials, ``open book'' programming lessons, several ``cookbook programs,'' and extensive documentation. Which of these will best suit your needs, and in what order you should use these materials, depends on your training/background and your immediate needs for using SPICE. NAIF suggests you become familiar with the offerings from the NAIF website (http://naif.jpl.nasa.gov), most particularly the tutorials and lessons collections. You might also take time to read the ``Introduction to the SPICE System'' document.

Please note that NAIF assumes you are familiar with how to write code in the language you have chosen, and that you know how to compile, link (``make'') and execute programs on your computer. If this is not the case you should first take some generic programming lessons before trying to tackle SPICE.
