Generated parser code contains error #3876
Description
I create a compiler with antlr and llvm in c++. I've created the two .g4 files and in my CMakeLists.txt I call the antlr jar to generate the lexer and the parser. Then I compile all my files with the same CMakeLists file and I got these errors :
Filc/src/generated/FilParser.cpp:803:16: error: invalid use of member function ‘antlrcppfil::FilParser::ExceptionContext* antlrcppfil::FilParser::ExprContext::exception()’ (did you forget the ‘()’ ?)
803 | _localctx->exception = std::current_exception();
| ~~~~~~~~~~~^~~~~~~~~
| ()
Filc/src/generated/FilParser.cpp:804:43: error: invalid use of non-static member function ‘antlrcppfil::FilParser::ExceptionContext* antlrcppfil::FilParser::ExprContext::exception()’
804 | _errHandler->recover(this, _localctx->exception);
| ~~~~~~~~~~~^~~~~~~~~
I looking in some tutorials and on stackoverflow why i've got these errors. But I didn't found any mention of that. And in tutorials code they have the same code as me, but it compile.
So I tried to update my antlr version to version 4.11.1 (originally I use 4.8) but it doesn't change anything.
For information, I use c++ 17, and this is my CMakeLists.txt :
