VS2015内联函数的链接错误 [英] VS2015 Linking errors for inline functions

问题描述

我们有一个项目，我们从VS2013转换为VS2015.该项目在VS2013中构建良好，但在VS2015中给出了链接器错误.

We have a project that we converted from VS2013 to VS2015. The project built fine in VS2013 but gives linker errors in VS2015.

我在VS2013和VS2015中创建了一个简单的测试应用，可以重现错误.

I have created a simple test app in VS2013 and VS2015 where the errors can be reproduced.

1.       该项目包含两个头文件.第一个标头(Declaration.h)包含函数声明，而第二个标头包含函数实现(Implementation.h).
2.      
3.        调用该函数的文件(LinkingErrors.cpp)仅包含声明.h

1.        The project contains two header files. First header (Declaration.h) contains function declaration whereas second header contains function implementation (Implementation.h).
2.        The function is implemented as inline.
3.        The file where the function is called (LinkingErrors.cpp) only includes declaration.h
4.        This linked fine in VS2013 but fails in VS2015.

以下是我的主要观察结果:

Following is the main observation that I have:

发现以下项目属性的组合会导致VS2015中的链接错误，但会在VS2013中成功构建.

Found that combination of following project properties causes linking errors in VS2015 but builds successfully in VS2013.

1. C/C ++属性->优化=>最大化速度(/O2)
2. C/C ++属性->优化=>仅__inline(/Ob1)

如果两个选项均设置为禁用，则可以解决VS2015中的链接错误，但我认为这不是正确的解决方案.

If both the options are set to disabled, it resolves the linking errors in VS2015 but I don’t think that the correct solution.

您好 Omkar Joshi ，

Hi Omkar Joshi,

我下载了您的代码，发现您在vs2015项目中注释了以下代码.如果我删除评论，那么效果很好.

I downloaded your code and I found that you comment the following code on the vs2015 project. If I remove the comment, it works well.

//#include "Implementation.h"

最诚挚的问候，
