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
我正在尝试编译一个第三方库(在linux上)，并看到它正在生成libsomething。一个文件，我有我的其他库。so文件
But it appears that even .a is shared library and can be used just like a .so lib
但似乎连a都是共享库，可以像so lib一样使用
So is there any difference between the two ? or they are just same with different naming convention.
那么这两者之间有什么区别吗?或者它们只是相同的命名惯例。

Nope, it's a static library.
不，它是一个静态库。
and can be used just like a .so lib
可以像。lib一样使用
If you mean linking to it, then yes. But you can't dlopen() an .a file which you could do with an .so file.
如果你的意思是链接到它，那么是的。但是不能使用.so文件来打开.a文件。

A .a file is a static library, while a .so file is a shared object dynamic library similar to a DLL on Windows.
. A文件是一个静态库，而.so文件是一个共享对象动态库，类似于Windows上的DLL。
A .a can included as part of a program during the compilation & .so can imported, while a program loads.
A . A可以在编译过程中作为程序的一部分被包含进来& .so可以在程序加载时被导入。

When you link against the *.a, the code from the library is included in the executable itself and the executable can be run without requiring the *.a file to be present. When you link against the *.so, that is not the case and the *.so file must be present at runtime.
当你链接到*。a，库中的代码包含在可执行文件本身中，可执行文件可以在不需要*的情况下运行。一份文件。当你链接到*。所以，情况不是这样的。所以文件必须在运行时出现。
