程序静态链接到一个库，但仍然需要dll运行 [英] Program statically linked to a library but still needs dll to run

问题描述

在链接方面我有一些不明白的东西...我正在使用第三方库（GEOS库）编写程序。该程序具有依赖于geos.lib但仍需要geos.dll来运行。

There are things that I don't understand when it comes to linking... I'm writing a program using a 3rd party library (the GEOS library). This program has a dependency to geos.lib but still needs geos.dll to run.

我阅读了这个问题，我想我了解静态和动态库之间的区别。我不明白的是为什么当我静态链接一个图书馆时，我仍然需要一个DLL。

I read this question, I think I understand the difference between static and dynamic libraries. What I don't understand is why I still need a dll when I statically link a library.

推荐答案

它没有静态链接。 .lib只是一个存根库，它绑定在Windows上的.dll中。也就是说，您在编译时与.lib链接，然后在运行时会查找.dll。

It's not statically linked. The .lib is just a stub library that binds in the .dll on windows. That is, you link with the .lib at compile time, and then at runtime it will go looking for the .dll.
