Why c header file is not generated using ANTLR works 1.5?

Question

I am trying to generate c code from ANTLR.grammar file, using antlrworks 1.5 (ANTLR 3.5) on windows, but it doesn't generate any header files, for example for sample.g it generates:
sample.tokens
sampleLexer.c
sampleParser.c

but not any header files and i can't figure out why.

The grammar what i am using now, is really simple for the sake of example:

grammar sample;

options 
{
language    = C;
}

rule1:
'ABC'   
;

I also get warnings such:

[12:39:44] warning(24):  template error: context [/outputFile /parser] 1:1 could not pass through undefined attribute filterMode
[12:39:44] warning(24):  template error: context [/outputFile /parser /genericParser /_sub721 /ruleAttributeScopeFuncMacro] 1:4 no such property or can't access: null.attributes
[12:39:44] warning(24):  template error: context [/outputFile /parser /genericParser] 155:5 no such property or can't access: null.apifuncs
[12:39:44] warning(24):  template error: context [/outputFile /parser /genericParser /rule /ruleDeclarations] 4:1 no such property or can't access: null.attributes
[12:39:44] warning(24):  template error: context [/outputFile /parser /genericParser /rule /ruleInitializations] 8:1 no such property or can't access: null.attributes
[12:39:44] warning(24):  template error: context [/outputFile /lexer /lexerRule /ruleDeclarations] 4:1 no such property or can't access: null.attributes

I have find an article about similar warnings on stackoverflow:
numerous template errors generating OracleSQL grammar using Antlr-3.5-complete.jar
(this is the only thing i have found out about this and i think it may not do anything about header files not being generated)

I would appreciate any help, i would like to generate some AST trees for my c++ project from some sql grammar i have made a long ago for java, but im stuck by this interesting issue.

Note:

I have also checked out all these articles:

Answer 1

It's likely a side effect of a bug that's already been resolved for ANTLRWorks 1.5.1 (coming within the next ~week).

Answer 2

I got the same problem with 1.5.0 Using 1.5.2 solves the problem. You can download it here http://www.antlr3.org/works/
