What is a file with extension .a?
提问by Blub
I downloaded this: https://github.com/mongodb/mongo-c-driver
我下载了这个：https: //github.com/mongodb/mongo-c-driver
And now I'm trying to use it inside my C program, but I don't know what to do with the generated .a files. What are they? I couldn't find any information, not even in the GCC manual.
现在我试图在我的 C 程序中使用它，但我不知道如何处理生成的 .a 文件。这些是什么？我找不到任何信息，甚至在 GCC 手册中也找不到。
And I built it like so:
我是这样构建的：
scons --c99
Also, can I use C99libraries with my C89 program?
另外，我可以在我的 C89 程序中使用C99库吗？

.afiles are staticlibraries typically generated by the archive tool. You usually include the header files associated with that static library and then link to the library when you are compiling.

.afiles are created with the arutility, and they are libraries. To use it with gcc, collect all .a filesin a lib/folder and then link with -L lib/and -l<name of specific library>.
.a文件是使用该ar实用程序创建的，它们是库。要与 一起使用，请将gcc所有内容收集.a files在一个lib/文件夹中，然后与-L lib/和链接-l<name of specific library>。
Collection of all .a files into lib/is optional. Doing so makes for better looking directories with nice separation of code and libraries, IMHO.
收集所有 .a 文件lib/是可选的。这样做可以使目录看起来更好，代码和库的分离很好，恕我直言。
