[Boost-users] boost::spirit and flex

Dear All,

I tried to integrate my flex scanner into boost::sprit.
I wrote my own iterator -- the value is int to represent the tokenid:

struct CScannerIterator:std::iterator<input_iterator_tag, int, ptrdiff_t, int*, int&>
{
....
        boost::any yylval;
        std::string m_sFileName;
        int m_iTokenId;
        int m_iLineNumber;
        
};

Then I tried to write my parser -- using chlit<int>(TokenId) to represent a token returned from the parser:

m_sExpression = chlit<int>(TK_INTEGER)[create_integer_expression(_rSelf.m_pStack)]

The problem is that the action for the chlit rule is getting passed an int instead of the iterator.
I need access to the yylval returned from the scanner.

Any idea on how to accomplish this?

Peter
