- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我首先将一个 utf-8 字符串转换为 utf-32,然后我希望将唯一的单词与其位置进行映射。我从 boost 语言环境开始。
#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;
}
它提示invalid use of incomplete type ‘const class boost::locale::boundary::boundary_indexing<char32_t>’
.怎么了 ?我有Ideone编辑它

最佳答案
It complains invalid use of incomplete type ‘const class boost::locale::boundary::boundary_indexing’ What's wrong?
char32_t
不受支持。使用
#define BOOST_LOCALE_ENABLE_CHAR32_T
但是你需要enable it在构建库期间,还有:
Experimental support for C++0x char16_t and char32_t strings and streams.
进一步查看:http://www.boost.org/doc/libs/1_64_0/libs/locale/doc/html/status_of_cpp0x_characters_support.html
If you want to build or test Boost.Locale with C++11 char16_t and char32_t support you should pass cxxflags="-DBOOST_LOCALE_ENABLE_CHAR32_T -DBOOST_LOCALE_ENABLE_CHAR16_T" to b2 during build and define BOOST_LOCALE_ENABLE_CHAR32_T and BOOST_LOCALE_ENABLE_CHAR32_T when using Boost.Locale
