我可以使用-gnu 0x标记成功编译eclipse cdt中的c 0x功能.虽然成功编译,编辑器似乎不知道c 0x,也就是说我的代码中显示了任何c 0x特性的错误.我通过将-gnu 0x标志添加到我的项目发现选项来解决.注意：在您执行其他编译并重建索引之前不会显示固定…

-E -P -v -dD “${plugin_state_location}/specs.cpp” -std=gnu++0x

我还有一个编辑器错误,我无法摆脱“符号”duration_cast’无法解决“(我有一个图片,但新用户不能发布图片)

任何人有什么想法如何解决这个问题？这是代码：

#ifndef _scoped_timer_h_
#define _scoped_timer_h_

#include <iostream>
#include <chrono>
#include "boost/noncopyable.hpp"
#include "boost/format.hpp"

using namespace std::chrono;

  // Utility class for timing and logging rates
// (ie "things-per-second").
// NB _any_ destructor invokation (including early return
// from a function or exception throw) will trigger an
// output which will assume that whatever is being measured
// has completed successfully and fully.
class scoped_timer : boost::noncopyable
{
public:


  scoped_timer(
    const std::string& what,const std::string& units,double n
  )
    :_what(what),_units(units),_how_many(n),_start(high_resolution_clock::now())
  {}

  ~scoped_timer() {
    high_resolution_clock::time_point stop = high_resolution_clock::now();
    const double t = 1e-9 * duration_cast<nanoseconds>(stop-_start).count();
    std::cout << (
      boost::format(
        "%1%: %|2$-5.3g| %|3$|/s (%|4$-5.3g|s)"
      ) % _what % (_how_many/t) % _units % t
    ) << std::endl;
  }

private:

  const std::string _what;
  const std::string _units;
  const double _how_many;
  const high_resolution_clock::time_point _start;
};

#endif
