'struct std :: _ List_iterator <sequence *>'没有名为'_Ptr'的成员。为什么？</序列*>

代码在Visual Studio中编译良好，但在使用g ++的Unix终端中编译。

g ++中弹出的错误：

在成员函数＆＃39; void SequenceDatabase :: processLine（string line）＆＃39;：

32,34,52,54：错误：＆＃39; struct std :: _ List_iterator＆＃39;没有名为＆＃39; _Ptr＆＃39;

的成员

我意识到使用_Ptr成员是为什么它不能使用g ++在Unix终端中工作，但是如何将它替换为在Visual Studio和Unix中工作？
