c++ - boost序列化中的编译错误， undefined reference

Question

我已经包含了这些头文件。

#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/serialization/map.hpp>
#include <boost/serialization/vector.hpp>

然后我有两行:

ofstream s_dict("save_dict.archive");
boost::archive::text_oarchive oa_dict(s_dict);

编译时:

g++ -lboost_serialization -lboost_system coord.cpp

它会抛出一长串错误，其中第一个错误是:

/tmp/ccRMDC8f.o:在函数中 boost::archive::text_oarchive::text_oarchive(std::ostream&, unsigned int)':
coord.cpp:(.text._ZN5boost7archive13text_oarchiveC2ERSoj[_ZN5boost7archive13text_oarchiveC5ERSoj]+0x25): undefined reference to boost::archive::text_oarchive_impl::text_oarchive_impl(std::ostream&, unsigned int)'

它正在获得对 boost 函数的 undefined reference 。

Answer 1

尝试重新排序 g++ coord.cpp -lboost_serialization -lboost_system
