我对 C++ 很陌生，所以我下载了一个示例 C++ 程序。示例程序在编译时似乎遇到了以下错误：-

Error   22  error LNK2019: unresolved external symbol _acsEnumServerNames@12    referenced in function "protected: virtual int __thiscall COpenTsrv::OnInitDialog(void)" (?OnInitDialog@COpenTsrv@@MAEHXZ)  Opentsrv.obj

我追踪到了引用的函数，但我不知道它有什么问题？

BOOL COpenTsrv::OnInitDialog() 
{
CDialog::OnInitDialog();

CenterWindow();


acsEnumServerNames(ST_CSTA, AddToList, (unsigned long) (CComboBox*)&m_TserverListControl);

UpdateData(FALSE);

以下是构建日志。显然还有其他错误，但想从第一个开始。

任何帮助我指出正确方向的帮助将不胜感激。

谢谢

好像你的编译成功了。只有链接不起作用。

可能链接器在抱怨，因为您定义了方法“acsEnumServerNames”的标头，但您没有提供该方法的实现。

也许您使用了头文件，但没有提供头文件所属的库？

找出“acsEnumServerNames”属于哪个包，并检查您是否在某个 .c/.cpp 文件中实现了该方法，或者该实现是否应该由您依赖的某个库提供。
