lnk4022：未修飾符號 - 如何修復？

Question

當我鏈接到我的C++ DLL程序時，我收到以下錯誤和警告：

顯然，在我的VS 2017年社區解決方案有很多init的存在，但我不知道他們來自。

的DEF文件是這樣的：

LIBRARY MTF_Garch 
EXPORTS 
    Init @1 
    OnParamsChange @2 
    Calculate @3 
    ReplaceStr @4 
    IntrfProcsRec @5 

而我是包括：

#include <windows.h> 
#include "IndicatorInterfaceUnit.h" 
#include "TechnicalFunctions.h" 
#include <string> 
#include <vector> 
#include "Garch.h" 

在Garch.h

#include <ql/auto_link.hpp> 
#include <ql/quantlib.hpp> 
#include <boost/geometry/index/detail/utilities.hpp> 
#include <ql/models/volatility/garch.hpp> 
#include <ql/math/optimization/simplex.hpp> 
#include <ql/math/optimization/levenbergmarquardt.hpp> 

我不使用ATL文件知道，儘管它是我創建的MFC DLL解決方案。剩下的我不確定它們是什麼。

因爲我對C++相當陌生，有人可以告訴我怎麼去告訴鏈接器它應該使用哪個Init（我知道有一個.def文件的EXPORT語法，但一直沒能找到文檔）或者我如何擺脫所有其他我不需要的東西。

謝謝。

您需要指定要在.def文件中導出的符號的損壞名稱。我發現這些常用方法是基於鏈接器錯誤消息中未定義符號的名稱。我將更新.def並重建。

查看您列出的候選人，您可能想要導出MTF_Garch文件中定義的符號。將您的導出文件中的「Init @ 1」行替換爲

?Init@@YGXXZ @1 

改爲。您也可以爲其他導出使用損壞的名稱，但由於鏈接器只發現一個可能的符號，因此目前不需要它們（但可能在將來）。
