Hello All,
using boost::wave (with context initialized as explained in the docs example) and trying to find
out if some certain macro is defined leads to 2 errors:
1. Doc for context state:
bool is_defined_macro(std::string const &name) const;
But the source has no such function definition. I assume the signature was changed to:
template <typename IteratorT2>
bool is_defined_macro(IteratorT2 const &begin, IteratorT2 const &end)
{ return macros.is_defined(begin, end); }
Trying to fix it and using the std::string::begin() and std::string::end() members to specify the
begin and end range result in the error:
c:\boost\include\boost-1_33_1\boost\wave\util\cpp_macromap.hpp(331) : error C2228: left of
'.get_value' must have class/struct/union
type is 'char'

template instantiation 'bool
boost::wave::util::macromap<ContextT>::is_defined<IteratorT2>(const IteratorT &,const
IteratorT &)' being compiled

IteratorT=char *
]

IteratorT=token_groups::str_iter_type,

IteratorT2=char *
]
This happens in cpp_macromap.hpp line 331:
function source:
template <typename ContextT>
template <typename IteratorT>
inline bool
macromap<ContextT>::is_defined(IteratorT const &begin,
IteratorT const &end)
{
// in normal mode the name under inspection should consist of an identifier
// only
token_id id = token_id(*begin);
if (T_IDENTIFIER != id &&
!IS_CATEGORY(id, KeywordTokenType) &&
!IS_EXTCATEGORY(id, OperatorTokenType|AltExtTokenType))
{
BOOST_WAVE_THROW(preprocess_exception, invalid_macroname,
impl::get_full_name(begin, end).c_str(), main_pos);
}
IteratorT it = begin;
error line >>>>>> string_type name ((*it).get_value()); <<<<<< error line
typename defined_macros_type::iterator cit(current_macros -> find(name));
if (++it != end) {
// there should be only one token as the inspected name
BOOST_WAVE_THROW(preprocess_exception, invalid_macroname,
impl::get_full_name(begin, end).c_str(), main_pos);
}
return cit != current_macros -> end();
}
I assume compiler dereferences iterator to char and char has no member to get_value. Does anyone
have suggestions?
With Kind Regards,
