.so和.a文件有什么区别? [英] what is the difference between .so and .a files?

问题描述

我正在尝试编译第3方库(在linux上)，并看到它正在生成libsomething.a文件，而我的其他库也是.so文件

I am trying to compile a 3rd party library( on linux) and see that it is generating libsomething.a files I have my other libraries which are .so file

但是看起来.a甚至是共享库，可以像.so lib一样使用

But it appears that even .a is shared library and can be used just like a .so lib

那么两者之间有什么区别吗?或它们只是具有相同的命名约定而已.

So is there any difference between the two ? or they are just same with different naming convention.

推荐答案

但是似乎.a还是共享库

But it appears that even .a is shared library

不是，这是一个静态库.

Nope, it's a static library.

，可以像.so lib

and can be used just like a .so lib

如果您打算链接到它，那么可以.但是您不能dlopen()一个.a文件，而该文件可以使用.so文件来完成.

If you mean linking to it, then yes. But you can't dlopen() an .a file which you could do with an .so file.
