错误LNK2019解析的外部符号(error LNK2019 unresolved external

我很新的C ++，所以我下载了一个示例C ++程序。示例程序似乎砸当编译以下错误： -

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

我把它追溯到提到的功能，但我不知道什么错呢？

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，但想先从第一个。

任何帮助，我指向正确的方向将非常可以理解的。

谢谢

好像你的编译是sucessfull。只有链接没有工作。

也许接头抱怨，因为你所定义的方法“acsEnumServerNames”的头，但你没有提供该方法的实现。

也许你使用的头文件，但你没有提供给这头所属的图书馆吗？

找出哪个PAKAGE“acsEnumServerNames”属于和检查，如果你有方法的实现，在一些.C / .cpp文件，或者如果实现，应该由其他图书馆提供在其上做依托。
