Antlr isn't really buggy, but the LL* versions (3 and up) can be
pretty picky about some things. Are you using the AntlrWorks tool to
create your grammar or are you just using a text editor?


It might help if you posted the grammar that breaks.

Antlr grammars won't work with Bison - they are not compatible.


Most tools do not have an IDE. I'm afraid I don't know of any
Unix/Linux IDEs for working with LR grammars. There are some for
Windows and some which run on JVM (which would work on any platform).
