C ++类

Question

当我尝试构建项目时遇到以下链接器问题。

我已经看过这里的其他帖子，据我所知，我使用的唯一外部是标准成员（并用std：:)或原语识别。有什么明显的东西我在这里不见了吗？

使用内部eclipse构建器在Win 7 professional 64bit上使用Eclipse C ++（Mars）构建。

日志：

  

link / debug / nologo /OUT:SAD-Snoop.exe“src \ ByteScanner.obj”“src \ EncType.obj”“src \ SAD-Snoop.obj”“src \ SearchHits.obj”

     

SearchHits.obj：错误LNK2019：未解析的外部符号“public：long __thiscall SearchHits :: GetHitAddress（unsigned int）”（GetHitAddress @ SearchHits @@ QAEJI @ Z）在函数“public：bool __thiscall SearchHits :: Merge”中引用class SearchHits）“（？Merge @ SearchHits @@ QAE_NV1 @@ Z）

     

SAD-Snoop.exe：致命错误LNK1120：1个未解析的外部

更改

long GetHitAddress(unsigned int hitNumber)

到

long SearchHits::GetHitAddress(unsigned int hitNumber)
