我尝试在 SystemC 项目中使用 boost 属性树。项目用途：

gcc 4.6.3
systemc 2.2
boost 1.46

标题：

#include <typeinfo>
#include <map>
#include <vector>
#include <string>
#include <exception>
#include <boost/property_tree/ptree.hpp> <-- line 17


class PersistenceProvider
{
static PersistenceProvider* m_instance;

//! private constructor to assure there is one instance
PersistenceProvider();

std::string GetTypePath(const std::string &name) const ;
std::string GetValuePath(const std::string &name)const ;

boost::property_tree::ptree m_ptree;
public:

 //! returns the current instance of the persistence provider
  static PersistenceProvider* getInstance();

  ~PersistenceProvider();

  template <class T>
  T get(std::string path);

  template <class T>
  void set(std::string path, T data);
};

代码：

template <class T>
T PersistenceProvider::get(const std::string path)
{
const std::string typePath = GetTypePath(path);
std::string type = m_ptree.get<std::string>(typePath);
if(typeid(T).name() != type)
{
    assert("wrong type");
}

const std::string dataPath = GetValuePath(path);
return m_ptree.get<T >(dataPath);
}

template <class T>
void PersistenceProvider::set(const std::string path, const T data) 
{
std::string type = typeid(T).name();
const std::string typePath = GetTypePath(path);
m_ptree.put<std::string >(typePath, type, true);
const std::string dataPath = GetValuePath(path);
m_ptree.put<T >(dataPath, data, true);
}

但是当我将 property_tree.hpp 添加到我的头文件时，gcc 会抛出以下内容：

还有更多人说同样的话..

这发生在包含时间而不是使用时。这可能是由于缺少包含或命名空间引起的吗？
