Hi,
I am taking a code sample from the documentation of Boost.Spirit (see https=
://www.boost.org/doc/libs/1_74_0/libs/spirit/doc/html/spirit/abstracts/attr=
ibutes/primitive_attributes.html), the code is as simple as is possible, li=
ke so:
1
2
3
4
5
6
namespace karma =3D boost::spirit::karma;
int value =3D 145;
std::string str;
std::back_insert_iterator<std::string> out(str);
karma::generate(out, boost::spirit::qi::int_, value); // str =3D=
=3D "123"
I get the error in the generate call: error_invalid_expression with the tem=
plate arguments as such:
OutputIterator=3Dstd::back_insert_iterator<boost::spirit::utf8_string>,
Expr=3Dboost::spirit::int_type,
Attr=3Dint
Other errors occur explaining this main error:
error C2039: 'properties': is not a member of 'boost::spirit::tag::int_'
error C2504: 'properties': base class undefined
error C2039: 'value': is not a member of 'boost::spirit::traits::properties=
_of<boost::spirit::tag::int_>'
Please help!!
Thanks
Juan
