boost 库的编译

kitty9fish

我现在在linux下编译一个用了boost/tokenizer.hpp库的源文件

代码如下：
#include <iostream>
#include <string>
#include <boost/tokenizer.hpp>


int main()
{
   std::string str1 = "I-have-a-dog";
   std::cout << str1 << std::endl;
   boost::char_separator<char> sep("-");
   boost::tokenizer<boost::char_separator<char> > tokens(str1, sep);

   for (tokenizer::iterator tok_iter = tokens.begin(); tok_iter != tokens.end(); ++tok_iter)
   {
      std::cout << *tok_iter << std::endl;
    }

}

用g++编译时，有错：
error: `tokenizer' has not been declared
error: `iterator' was not declared in this scope
error: expected `;' before "tok_iter"
error: `tok_iter' was not declared in this scope
请问是怎么回事？

cores

#include "boost/tokenizer.hpp"
boost库路径设置了吗？
