RE: bison %union and C++

[Hart, Justin]

Quick and dirty way...

Use pointers, they don't need to be initialized so they are legal for union.

Slightly different way...

Don't use %union to declare yystype.  Declare it as a class.  Then classes
are legal.

Subject: bison %union and C++


Hello there,

here is a question that is probably asked for a millionth time....
But, I have done a lot of googling - honestly :)

Anyway, with bison 1.49b and C++ skeleton, how do I include a C++
class into the bison's types? In theory, I would like to add
std::string into the %union section, but this is prohibited by ANSI
C++.

So, is there any way to get bison to store one of my objects on its
stack?

Thanks in advance,
Oleg Smolsky
