glr2.cc does not work for me. I get compile errors with the resultant parser and scanner files that are generated.
To be honest, I'm not quite sure where to begin in regards to figuring out the problem. >From what I've read: "It should be upward compatible in terms of interface, feature and performance to "glr.cc". To try it out, simply use %skeleton "glr2.cc" Since I wanted to look at the %merge feature again, I decided to update everything and give that a try. I am not sure if I am messing something up or if there is an issue somewhere. Here is a summary of the situation: I'm running Windows 10, developing with MSVC 2022 and using cygwin for flex/bison. I used to use win_flex/win_bison on sourceforge but it hasn't been updated for a year, and I wanted to use the latest versions of flex and bison. I installed the 64 bit version of cygwin and installed flex/bison thru their setup interface. The flex/bison versions are: flex 2.6.4 bison (GNU Bison) 3.8.2 I then added the bin directory to my PATH and copied flexlexer.h into another directory so I could set my MSVC "Additional include dir" to it. (I can't set MSVC directly to the /usr/include since MSVC was using additional files from it which caused multiple errors. Anyways, that worked fine. After some minor changes for MSVC, I verified everything was working by recompiling my source (using glr.cc) and everything works as before. I then set my parser's skeleton to glr2.cc Flex and bison do their work, and report the expected amount of s/r r/r conflicts. I then compile the generated code but I get multiple errors compiling both files. 1>parser.cpp 1>D:\data\c\gen\runtime\parser.h(480,1): error C2535: 'gen::Parser::basic_symbol<Base> &gen::Parser::basic_symbol<Base>::operator =(const gen::Parser::basic_symbol<Base> &)': member function already defined or declared 1>D:\data\c\gen\runtime\parser.h(435): message : see declaration of 'gen::Parser::basic_symbol<Base>::operator =' 1>D:\data\c\gen\runtime\parser.h(482): message : see reference to class template instantiation 'gen::Parser::basic_symbol<Base>' being compiled 1>D:\data\c\gen\runtime\parser.h(480,1): error C2535: 'gen::Parser::basic_symbol<gen::Parser::by_kind> &gen::Parser::basic_symbol<gen::Parser::by_kind>::operator =(const gen::Parser::basic_symbol<gen::Parser::by_kind> &)': member function already defined or declared 1>D:\data\c\gen\runtime\parser.h(435): message : see declaration of 'gen::Parser::basic_symbol<gen::Parser::by_kind>::operator =' 1>D:\data\c\gen\runtime\parser.h(529): message : see reference to class template instantiation 'gen::Parser::basic_symbol<gen::Parser::by_kind>' being compiled 1>D:\data\c\gen\runtime\scanner.h(35,55): error C2039: 'semantic_type': is not a member of 'gen::Parser' 1>D:\data\c\gen\runtime\parser.h(122): message : see declaration of 'gen::Parser' ... etc (the other messages look like msvc is past the point of generating meaningful messages). Does anyone have experience with a similar setup? I wonder if I messed something up or should I send this to bug-bison? Any guidance would be appreciated. Thanks
