Generate C ++ code for BNF grammar

Question

I reviewed the following software tools:

• Ragel
• ANTLR
• Bnf converter
• Boost :: Spirit
• Coco / R
• Yacc

ANTLR seems the most direct, but its documentation is lacking. Ragel looks the same, but I don’t see an easy way to convert BNF to its syntax.

What other tools are available that can accept BNF input and create an appropriate, Unicode-compatible, cross-platform, stand-alone, C ++ parser?

Thanks so much for all the suggestions.

Edit: Changed the Objective-C requirement for C ++.
