2234,Spirit2/Phoenix compilation error (front on iterator_range),François Barel <frabar666@…>,Joel de Guzman,"The following source:

{{{
#include <boost/spirit/include/qi.hpp>
using namespace ::boost::spirit;
using namespace ::boost::spirit::qi;
using namespace ::boost::spirit::arg_names;

#include <boost/spirit/include/phoenix_stl.hpp>
using namespace ::boost::phoenix;

int main()
{
        rule< const wchar_t* > r;
        r = raw[ wchar ][ front(_1) ];

        return 0;
}
}}}

worked several months ago (before Spirit2 was brought in Boost svn), but no longer compiles with current svn-trunk, gcc gives the following error:

{{{
.../boost/spirit/home/phoenix/stl/container/detail/container.hpp:42:
  error: no type named ‘const_reference’
         in ‘const class boost::iterator_range<const wchar_t*>’
}}}

It seems due to r44555 which made attributes const in actions, as {{{boost::iterator_range}}} does not contain a {{{const_reference}}} typedef.

Note that replacing {{{front}}} with {{{*begin}}} works around the problem, since {{{boost::iterator_range}}} does contain a {{{const_iterator}}} typedef.

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}}}.",Bugs,closed,Boost 1.37.0,spirit,Boost 1.36.0,Regression,fixed,spirit phoenix action attribute const front iterator_range,
