NEWBIE Questions: ANTLR 4 and C++ run time

[mehrdad ghassempoory]

I have been using the ancient ANTLR 2.7.7 with C++ run time. 

I would like to migrate to ANTLR 4, but there does not seem to 

be a live link to C++ run time in antlr.org site. Does this mean 

that C++ is not officially supported? I have seen a C++ run time 

library on https://github.com/antlr/antlr4/tree/master/runtime/Cpp. 

Is this the correct library to use? Is there any documentation on

C++ library? Where do I start? Any help or pointers is most 

welcome.

What link do you expect? Can you share an example for another supported language? I see on the download page (http://www.antlr.org/download.html) links to all supported languages. Does this count?

If something looks like a duck and behaves like a duck it’s likely a duck ;-)

Yes.

Two places mostly:

1) https://github.com/antlr/antlr4/blob/master/doc/cpp-target.md, describing the differences for the C++ target compared to Java.
2) The runtime source folder, which contains an example you should be able to compile as is (there’s a readme too).

Ask here or on Stackoverflow (preferred) for detail question you may find on the way.
