I would like to build a cpp parser using cpp and I’m using ANTLR4. I notice there is this ‘grammar’ section from the official github antlr grammar github and I’ve downloaded it. While opening the CPP file inside, I notice there is a CPP14Parser and a CPP14Lexer, also there’s another CPP file with a CPPParser in it. I’ve been running through the documentations for days but it seems it was outdated. I’ve tried running antlr-4 but later I kept getting and error when trying to compile it. However, the CMakeLists.txt and main(basically all other file) I wrote does work on an older version where things are more clean The version I successfully build. Can somene please teach me how to build the latest version of current grammar? Please let me know if any more specific context is needed! Thanks in advance!
