Boost C++ Libraries: Ticket #2234: Spirit2/Phoenix compilation error (front on iterator_range)

Re:

I don't know enough about iterator_range and Phoenix type deduction to know in which one this should be fixed... please tell me if I should submit a feature request ticket to add a const_reference typedef to iterator_range.

Perhaps it's a good idea to minimize the problem to something that calls iterator_range directly and ask the author (Thorsten Ottosen & Pavol Droba) about it on the devel list.

I think this has been fixed somewhere. The following compiles:

#include <boost/spirit/include/qi.hpp>
#include <boost/spirit/include/qi_char_.hpp>
using namespace ::boost::spirit;
using namespace ::boost::spirit::qi;
#include <boost/spirit/include/phoenix_stl.hpp>
using namespace ::boost::phoenix;
int main()
{
        rule< const wchar_t* > r;
        r = raw[ char_ ][ front(_1) ];
        return 0;
}

I can confirm that the code in the second comment compiles [ Mac OS X 10.6.2 / gcc 4.2.1/ boost trunk ], but the original poster's code does not.

junk.cpp:4: error: ‘arg_names’ is not a namespace-name
junk.cpp:4: error: expected namespace-name before ‘;’ token
junk.cpp: In function ‘int main()’:
junk.cpp:12: error: ‘wchar’ was not declared in this scope

status changed; resolution set

status new → closed
resolution → fixed

The original code was for Spirit 2.0. As reported by commenter #2, it now works on trunk (r58133).

The issue must have been solved when Spirit 2.1 was merged.
