повысить языковой стандарт неполного типа border_indexing & lt; char32_t & gt;
Сначала я конвертирую строку utf-8 в utf-32, а затем хочу, чтобы уникальные слова отображались с их позициями. Я начал с повышения языкового стандарта.
#include <iostream>
#include <string>
#include <chrono>
#include <boost/shared_ptr.hpp>
#include <map>
#include <list>
#include <boost/locale.hpp>
typedef std::u32string string_type;
typedef std::pair<unsigned long, unsigned long> range_type;
typedef std::map<std::string, std::list<range_type>> wordref_type;
struct parser{
/**
* returns a map of "words" with its positions list
*/
static wordref_type parse(string_type::const_iterator b, string_type::const_iterator e){
wordref_type wordrefs;
range_type sentence;
boost::locale::boundary::segment_index<string_type::const_iterator> index(boost::locale::boundary::word, b, e);
//TODO: iterate index
return wordrefs;
}
};
int main(int argc, char** argv){
std::string input_str = "Some UTF-8 texts";
string_type buffer = boost::locale::conv::utf_to_utf<string_type::value_type>(input_str); // convert utf-8 to utf-32
wordref_type wordrefs = parser::parse(buffer.cbegin(), buffer.cend());
return 0;
}
Жалуется invalid use of incomplete type ‘const class boost::locale::boundary::boundary_indexing<char32_t>’, Что случилось ? я имею Ideone‘редактировать

Решение
Вам нужно скомпилировать форс с BOOST_LOCALE_ENABLE_CHAR32_T включить boundary_indexing<char32_t> но …
[акцент мой]Состояние поддержки C ++ 11 char16_t / char32_t
Поддержка C ++ 11
[….]char16_tа такжеchar32_tэкспериментальный, в основном не работает и не предназначен для использования в производстве с текущими последними компиляторами: GCC-4.5, MSVC10, пока основные недостатки компилятора не будут исправлены.Если вы хотите собрать или протестировать Boost.Locale с поддержкой C ++ 11 char16_t и char32_t, вы должны передать

Другие решения
Он жалуется на недопустимое использование неполного типа boost const class boost :: locale :: border :: border_indexing ’Что не так?
char32_t не поддерживается. использование
#define BOOST_LOCALE_ENABLE_CHAR32_T
Но вам нужно включить это во время строительства библиотеки, а также:
Экспериментальная поддержка строк и потоков C ++ 0x char16_t и char32_t.
