[antlr-interest] Ang: Re: Newbie C-code generation

[mimarob at algonet.se]

Hmm I'm pretty sure I haven't got a pre installed antlr on my system

I downloaded the package from http://www.antlr.org/download/antlr-3.1
b1.tar.gz

Here is my classpath:

.;c:\Documents and Settings\qeribra\cgram\cgram\grammars;c:\Documents 
and Settings\qeribra\antlr\antlr-3.1b1\lib\antlr-3.1b1.jar;c:\Documents 
and Settings\qeribra\antlr\antlr-3.1b1\lib\antlr-2.7.7.jar;c:\Documents 
and Settings\qeribra\antlr\antlr-3.1b1\lib\stringtemplate-3.1.jar;c:
\Documents and Settings\qeribra\antlr\antlr-3.1b1\lib\antlr-runtime-
current.jar;c:\Documents and Settings\qeribra\antlr\antlr-3.1
b1\lib\gunit-1.0.2.jar


When I try to remove the antlr-2.7.7.jar I get the 

java.lang.NoClassDefFoundError: antlr/Tool

error.

I thought the antlr-3.1b1.jar was the new antlr or?

You are suing ANTLR 2.7.7 not ANTLR 3, so you cannot generate C code.
Remove the pre-installed antlr 2 package from your system and download
the ANTLR 3 atr from the dowloads section of the web site.
