! JDK versions and the care and feeding of your CLASSPATH 

<B>JDK Versions</B>
We have traditionally attempted to build everything under JDK 1.1.x in order to preserve some hope of compatibility with Mac OS. Now that Mac OSX include JDK 1.3 and modern linux distributions appear to have problems with JDK 1.1, moving towards JDK 1.3 seems more reasonable.

<B>Classpaths</B>
When building the source tree with make, the <CODE>linc/build/Config.xxx</CODE> file will take care of constructing an appropriate classpath for the compiler.

For running code from the source tree you may need to include some subset of the jars listed in <CODE>Config.xxx</CODE> in your classpath, along with the path to the <CODE>linc/classes</CODE> directory. In general, if you get <CODE>NoClassDefFoundError</CODE> errors, you are missing a jar file.

Note that if you are running under JDK 1.1 you need the <CODE>swingall.jar</CODE> file in your classpath for most of the CHCI software, along with <CODE>classes.zip</CODE> from the jdk directory. If you are running under later versions of the JDK (1.2+), you should not include either of these files in your classpath.
