[antlr-interest] Problem running 2.7.3rc2 (incl. quick fix)

[Simon Kellett]

I have an interesting run-time error.

> export CLASSPATH="/home/skellett/local/share/antlr-2.7.3"
> java antlr.Tool calc.g
Exception in thread "main" java.lang.NoClassDefFoundError: antlr/Tool

> java -cp /home/skellett/local/share/antlr-2.7.3 antlr.Tool calc.g
Exception in thread "main" java.lang.NoClassDefFoundError: antlr/Tool

(i.e. no differences)

However, running through truss I see that java is looking for 
/home/skellett/local/share/antlr-2.7.3/antlr/Tool.class

So I created a softlink in /home/skellett/local/share/antlr-2.7.3
> ln -s ../../src/antlr-2.7.3rc2/antlr

And java is happy !! It looks like the .class files need to be
installed in the "share" area, but I do not know if this is the
correct solution as I know nothing about Java !!
