在Visual C ++ LNK2005，LNK2019链接错误 - 不知道为什么

Question

我想从nVidia的9.5 SDK构建的代码，但我得到下面的连接错误：

我不知道为什么我刚开gthese恐惧，因为我敢肯定，我设置99％，我的目录正确。

例如它不能找到的功能之一是TextureFactory :: CreateTextureFromFile但我具有其中该函数声明和定义已经添加到包括/源目录在Visual C ++设置的目录。

顶文件看起来像这样：

#include "nvafx.h"
//#include "NV_D3DCommon\NV_D3DCommonDX9.h"  // include library sub-headers
                                             // and add .lib to linker inputs
//#include "NV_D3DMesh\NV_D3DMesh.h"

//#include "shared\NV_Common.h"
//#include "shared\NV_Error.h"

#include "FogTombScene.h"
#include "ThicknessRenderProperties.h"
#include "ThicknessRenderProperties8BPC.h"
#include "../camera.h"


// When the following two lines are added I get more LNK2005 (understandable) 
// but I also still get the same LNK2019 errors as above
#include "texturefactory.h"
#include "texturefactory.cpp"

更重要的一点，如果我说的#include“TextureFactory.h”和＃包括“texturefactory.cpp”在这我得到这些错误然后将文件的顶部就没有余地歧义，功能被定义，基本上复制+粘贴到相同的源文件生成的连接错误，但我仍然得到连接错误。

我俯瞰的东西吗？

Answer 1

这happend因为：

1的.lib的源极缺少像所述tomzx或丹尼尔， 要么 2的.lib它已在Visual C的另一版本编译   尝试创建自己的文件中像记事本中的.C（不是一个.cpp），然后添加到您的项目文件.C（项目......添加到项目...文件）

对不起，我的墨西哥，我不会说英语。 Saludos。

Answer 2

您已经添加在包括/源文件夹怎么样的库文件，但？看起来更像一个库问题我（缺少的.lib）。

也许你还需要列出你的依赖在链接器 - 输入

。

LNK2005通常意味着其它附加库不正确链接。

Answer 3

您可能忘了链接到的SDK LIB文件之一。您可以设置此项目中的属性下连接器 - >输入 - >附加依赖或使用的＃编译注释。
