Re: [Boost-users] [Spirit] leaf_node_d compile time error

Hey Chris,

Hi, I'm upgrading some code from boost 1.33 to 1.38, and upgrading compilers from gcc 4.1 to 4.3.3. Code that used to work is no longer compiling, and I'm running out of ideas what might be the problem. While the real code is significantly larger, I've managed to extract the problem down to this short example.

#define BOOST_SPIRIT_USE_OLD_NAMESPACE #include "boost/spirit/include/classic_core.hpp" #include "boost/spirit/include/classic_ast.hpp"

This needs to be: #include "boost/spirit/include/classic_parse_tree.hpp"

using namespace boost::spirit;

struct Test_Parser : public grammar { template <typename ScannerT> struct definition { definition(Test_Parser const & /*self*/) {

test_filter = leaf_node_d[ ch_p('=') ] //<<<<<<< HERE ; } rule<ScannerT> test_filter; rule<ScannerT> const & start() const { return test_filter; } }; };

int main() { using namespace boost::spirit; char const * str = "="; Test_Parser parser; parse_info<> info = parse(str, parser, space_p);

And this: tree_parse_info<> info = pt_parse(str, parser, space_p); Then it should compile. HTH Regards Hartmut

}

When I use leaf_node_d[], it doesn't compile. Removing leaf_node_d, and all is well. The error is ugly, but ultimately is this: error: no type named node_factory_t in class boost::spirit::leaf_node_parser<T>::parse(const ScannerT&) const

I've spent a few hours trying to grok the code and am falling short. Any help would be appreciated.
