[antlr-interest] grammar checking/compilation fails on Windows butnot on Linux

[Sam Harwell]

Change your postfixExpression to this:

 

postfixExpression

        : leftHandSideExpression (('++'|'--') => ( '++' | '--' )?)

        ;

Subject: [antlr-interest] grammar checking/compilation fails on Windows butnot on Linux

 

Hello,

I am facing here something weird.


I have a grammar which compiles fine under Linux (Ubuntu 64 bits, 4GB ram) and passes the grammar checking performed by AntlrWorks. (not even a single warning)

On a Windows XP machine (32bits, 3GB ram) both the compilation and checking fail.

The grammar file is accessible from http://code.google.com/p/jsdet/source/browse/trunk/src/grammars/JavaScript.g

Can somebody tell me if passes on his/her AntlrWorks checking feature?

thanks
