c++ - 错误 C2732 : linkage specification contradicts earlier specification for 'log'

Question

我写了一些函数，并编译成一个dll模块。在我的头文件中如下:

#ifndef GET_DATAFEED_FORKDB_H
#define GET_DATAFEED_FORKDB_H

#include "..\include\stdafx.h"
#include <windows.h>

#include "..\include\TDFAPI.h"
#include "..\include\TDFAPIStruct.h"
#include "..\include\PathHelper.h"
#include "..\include\ConfigSettings.h"

// some helper functions
// ....

extern "C" void openConnect();
extern "C" void closeConnect();

#endif 

但是，当我使用 Visual Studio 2013 Professional 编译它时，出现了一些错误:

F:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\math.h(501) :
  error C2732: linkage specification contradicts earlier specification for  'log'
F:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\math.h(501) : 
 see declaration of 'log'
F:\Program Files (x86)\Microsoft Visual Studio12.0\VC\INCLUDE\xtgmath.h(104)
  :error C2732: linkage specification 
  contradicts earlier specification for 'log'
F:\Program Files (x86)\Microsoft Visual Studio12.0\VC\INCLUDE\xtgmath.h(104)
  : see declaration of 'log'
F:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\xlocale(337)
  : warning C4530: C++ exception handler used, but unwind semantics are not 
   enabled. Specify /EHsc

我没有用过数学方法。所以我尝试使用 this method解决它，但它没有用。包含的头文件不能不修改，我也试过用这个方法:

 extern "C" {
    #include "..\include\TDFAPI.h"
    #include "..\include\TDFAPIStruct.h"
    #include "..\include\k.h"
    #include "..\include\PathHelper.h"
    #include "..\include\ConfigSettings.h"
  }

，更糟糕的是，它发生了更多的错误。

刚遇到和你一样的问题。我遇到了和你一样的问题。 #include "k.h" 必须放在包含任何标准 header 之后。
