出现如下连接错误：
Linking...
main.obj : error LNK2001: unresolved external symbol "void __cdecl treemain(void)" (?treemain@@YAXXZ)
main.obj : error LNK2001: unresolved external symbol "void __cdecl pathmain(void)" (?pathmain@@YAXXZ)
main.obj : error LNK2001: unresolved external symbol "void __cdecl sonmain(void)" (?sonmain@@YAXXZ)
Debug/main.exe : fatal error LNK1120: 3 unresolved externals
请大家指教

是不是 在类定义外面用了inline？？？？如果是就直接把inline 干掉，或者把方法直接扔到类定义里面去！
