The compiler can't find the .class file for the ANTLR runtime. Try:
$ java -cp antlr-3.2.jar org.antlr.Tool T.g
$ javac -cp antlr-3.2.jar *.java
$ java -cp .:antlr-3.2.jar Main
instead.
I tested it with ANTLR 3.2 (the site is down so couldn't download 3.3) with
the following class:
import org.antlr.runtime.*;
public class Main {
public static void main(String[] args) throws Exception {
ANTLRStringStream in = new ANTLRStringStream("call f;");
TLexer lexer = new TLexer(in);
CommonTokenStream tokens = new CommonTokenStream(lexer);
TParser parser = new TParser(tokens);
parser.r();
}
}
