c – 头文件中“”标记之前的预期初始值设定项”

我目前正在将许多曾经在main()中的代码重新打包到Simulation类中.我在这个类的头文件中遇到编译错误.我正在使用gcc 4.2.1版进行编译.

// Simulation.h
#ifndef SIMULATION_H
#define SIMULATION_H

typedef std::set<int> HHSet;

  ~Simulation();

  std::string ageDistFile;

  std::string hhDistTFile;
};

#endif

我希望其他文件与这个问题不太相关.当我编译时

g++ -g -o -c a.out -I /Applications/boost_1_42_0/ Host.cpp Simulation.cpp rng.cpp main.cpp Rdraws.cpp

我明白了

Simulation.h:33: error: expected initializer before '<' token
Simulation.h:102: error: 'HostContainer' does not name a type

然后是一堆与无法识别HostContainer相关的其他错误.

看起来我对HostContainer的所有正确的Boost #includes都有所了解.还有什么可能出错？

我将非常感谢有关我的代码的即时建议,疑难解答提示和其他建议.我的计划是创建一个“HostContainer.h”文件,其中包含定义其标记的typedef和结构,类似于我在EventPQ容器的“Event.h”中所做的.我认为这是合法的,良好的形式.
