编译错误指向 wxWidgets\include\wx\string.h是为什么？

别人建的project，我在上面做修改，开始的时候没有问题，可以正常运行，后来加了不少代码上去，期间一直没编译，结果今天编译就出了如下的error：
c:\wxWidgets\include\wx\string.h(1570) : error C2593: 'operator +' is ambiguous
c:\wxWidgets\include\wx\string.h(1572) : error C2593: 'operator +' is ambiguous
c:\wxWidgets\include\wx\arrstr.h(233) : fatal error C1903: unable to recover from previous error(s); stopping compilation
请问下这个可能的原因是什么呢？
谢谢。

重载的operator +有问题吧

并且一直有很多关于库函数的warning，如下：

只截了一部分，请问这个又是什么原因呢？

我自己并没有关于 operator+的函数啊，怎么会有重载的问题？

#4

//wx\string.h
//233
#if defined(__VISUALC__) && (__VISUALC__ >= 1200)
  __forceinline
#endif
//1570
inline bool operator!=(const wxChar  * s1, const wxString& s2)
    { return s2.Cmp(s1) != 0; }
//1572
inline bool operator< (const wxString& s1, const wxString& s2)
    { return s1.Cmp(s2) < 0; }

可能你在追踪代码是无意中把operator!=和operator<给替换成了operator+或不下心添加或删除了什么
随便问一下你是用什么编译啊？

#5

这么多警告啊
你最好设断点跟踪一下

#6

是不是你用的wxWidgets和VC里自带的string冲突了。

应该不是我误操作了，我从来不去库里改东西的，你就当我是菜鸟新手。

把你的wxWidgets的string给注释了

估计有类库重复了
