程序静态链接到库，但仍需要dll运行 [英] Program statically linked to a library but still needs dll to run

问题描述

有些事情我不明白，当谈到链接...我正在使用第三方库（GEOS库）编写程序。这个程序对geos.lib有一个依赖，但仍然需要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，我想我理解静态和动态库之间的区别。我不明白为什么我静态链接库时仍需要一个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

它不是静态链接。 .lib只是一个存根库，在Windows上的.dll中绑定。也就是说，你在编译时链接到.lib，然后在运行时它会去寻找.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.
