这样写：spNextOutputer->put(note+turnLevel);//note.operator+()返回的是Note对象
出现这样的错= =

然后这样就对了
Note newNote = note+turnLevel;
spNextOutputer->put(newNote);
到底发生了什么？msvc这段是没问题的。


表示不解，回去试试。

你确定你的operator+的重载没问题？

Ly::TokenOutputer::put(Ly::Token&)
改成
Ly::TokenOutputer::put(const Ly::Token&)
需要的话还可以加一个
Ly::TokenOutputer::put(Ly::Token&&)

取巧了一下= =基类加了个函数
int put(const Token& _token){return put(const_cast<Token&>(_token));}
坏方法，大家不要学
