链接:致命错误 LNK1561:必须在空项目中定义入口点 [英] LINK : fatal error LNK1561: entry point must be defined in empty project

问题描述

我使用 Visual Studio 2017 15.3.4 社区版创建了一个 Visual C++ 空项目，选择 Visual C++ -> 常规 -> 来自向导的空项目.我想创建一个 C++ 库(静态或动态).

I have created a Visual C++ empty project with Visual Studio 2017 15.3.4 Community edition selecting Visual C++ -> General -> Empty project from wizard. I wanted to create a C++ library (static or dynamic).

但是当我编译它时，我收到此消息:

But when I compile it I get this message:

LINK:致命错误 LNK1561:必须定义入口点

LINK : fatal error LNK1561: entry point must be defined

我已右键单击项目"，选择属性"、链接器"和高级"，入口点"选项为空.

I have right clicked on Project, select Properties, Linker and advanced and Entry Point option is empty.

我必须在那里放什么?

还有其他更好的选择来创建 C++ 库吗?

Is there another better option to create a C++ library?

推荐答案

库没有入口点，因此您可以判断项目配置不正确.您忘记更改的特定设置是项目 > 属性 > 常规 > 配置类型.选择静态库(.lib)".

A library does not have an entrypoint, so you can tell that the project is not configured correctly. The specific setting you forgot to change is Project > Properties > General > Configuration Type. Select "Static library (.lib)".

这是错误的，因为您从头开始，必须正确设置数十项从来都不是问题.对于 VS2017 RTM，您会喜欢从 Win32 > Win32 Project > Next > "Static library" 单选按钮开始.也许这改变了，我没有更新它，因为我看到了太多关于 15.3.x 的讨厌的错误报告

This went wrong because you started from scratch, having to get dozens of settings right is never not a problem. For VS2017 RTM you'll favor starting from Win32 > Win32 Project > Next > "Static library" radio button. Maybe that changed, I haven't kept it updated because I've seen too many nasty bug reports for 15.3.x
