This says "I couldn't find the Tool.class file in D:\antlr-2.7.6\antlr"

You should build antlr itself first.


If you can't (or won't) build antlr, make the following changes to the *original* csharp_v1.build

1. Find this line:
	    <property name="antlr.dir" value="..\..\.."/>

  Add the following below it:
	    <property name="antlr.cp" value="..\..\..\antlr.jar"/>


2. Find this line:
    <target name="generate" description="calls ANTLR to generate Lexers/Parsers">    	

   Change all occurences of ${antlr.dir} IN THIS TARGET ONLY (i.e. between <target ..> and the closing </target>) to:
	${antlr.cp}

This changes basically say, "use the version of the antlr .class files found in antlr.jar". Consequently. any changes you've made to your local copy of the antlr tool's sources would not be reflected here obviously.

Don't do this  ;-)
