[antlr-interest] Help!!!

[ronald.petty at milliman.com]

Hi Tonie,
Not sure this will help, but I am attempting the same thing and haven't 
finished it yet either.  To compile I did

// cd to the antlr dir, I haven't figured out the right way in cygwin to 
set my classpath
javac -cp ./antlr.jar *.java

That should fix the second issue.

Now what you can't find Main, I am not sure.

I do not have a Main.class, you have to create it I think (there may be 
one).  You list the generated files (ExprLexer.java, ExprParser.java, 
ExprParserTokenTypes.java, ExprParserTokenTypes.txt), but nothing about 
Main.java.  Was there a Main.java generated?  If not, create one and 
inside main() do

ExprLexer el = new ExprLexer(...input stream...);
ExprParser ep = new ExprParser(el);
ep.startsymbol // not sure about after this...

Hope I didn't say something incorrect (as I am learning also).

Good luck.

Ron

[antlr-interest] Help!!! 






Hello, 

I am a newbie in antlr. 

I believe I have configed the CLASSPATH correctly, because
I can use antlr.Tool expr.g to generate:

ExprLexer.java
ExprParser.java
ExprParserTokenTypes.java
ExprParserTokenTypes.txt

It seems work well.

Then I type javac *.java, nothing wrong.
But when I want to run the Main class: java Main,
I always got NoClassDefException :(

I 've tried many times and the results are same.
By the way, when I compiled the *.java files, if I compile
them individulely, I will got errors. Just like it cannot find
the antlr.* package.

If you can help me with this, it would be very nice.

Thank you!

Tonie
