Boost序列化编译问题

xml-serialization boost serialization xml c++

0x26res · 技术社区 · 14 年前

我正在Windows上使用Boost序列化,我想在Linux(Ubuntu)上测试我的代码,但不幸的是它没有编译。

#include <string>
#include <fstream>

#include <boost/archive/xml_iarchive.hpp>
#include <boost/archive/xml_oarchive.hpp>


#include <boost/serialization/string.hpp>
#include <boost/serialization/nvp.hpp>
#include <boost/serialization/export.hpp>


class MyClass
{
  public:
    int something;
    MyClass();

    template<class archive> void serialize(archive& ar, const unsigned int version)
    {
      using boost::serialization::make_nvp;
      ar & make_nvp("something", something);
    }


};



MyClass::MyClass()
  : something(0)
{
}

int main(int argc, char ** argv)
{
  std::cout << "Hello";
  MyClass obj();

  std::string path = "here.xml";

  std::ifstream ifs(path.c_str());
  if (ifs.good())
  {
    boost::archive::xml_iarchive ia(ifs);
    ia >> boost::serialization::make_nvp("obj", obj);

    ifs.close();
    return true;
  }
  else
    return false;

}

这是我的编译行:

g++ test.cpp -lboost-serialization

我得到的是:

In file included from /usr/include/boost/archive/detail/interface_iarchive.hpp:23,
                 from /usr/include/boost/archive/detail/common_iarchive.hpp:21,

                 from test.cpp:6:

我可能缺少一个包含…

你遇到了 Most Vexing Parse . 在你的主要方法中,改变

MyClass obj();

到

MyClass obj;

另外,在我的Linux系统上,链接线是

g++ test.cpp -lboost_serialization

注意下划线而不是破折号,就像在示例中一样

g++ test.cpp -lboost-serialization
