如何将多个库档案(.a)打包到一个档案文件中? [英] How to pack multiple library archives (.a) into one archive file?

问题描述

如何在Linux上使用binutils ar和/或GCC将多个存档文件转换为一个大存档文件.

How can I turn multiple archive files into one big archive file on Linux (using binutils ar and / or GCC).

我尝试做类似ar rcs libbig.a libsmall1.a libsmall2.a的操作，但它不起作用(结果libbig.a为空).

I tried doing things like ar rcs libbig.a libsmall1.a libsmall2.a and it doesn't work (the resulting libbig.a is empty).

推荐答案

仅在我的机器上尝试过，问题似乎是您需要从归档中提取对象，然后再将它们添加到新的归档中:

Just tried this on my machine and the problem seems to be that you need to extract the objects from the archives before adding them to the new archive:

ar x libsmall1.a
ar x libsmall2.a
ar rcs libbig.a *.o

像您一样简单地运行ar rcs会生成一个包含两个.a文件的存档，但是工具(例如nm)不愿意深入研究这些文件.

Simply running ar rcs like you did produced an archive which contained two .a files, but tools (e.g. nm) were unwilling to look deeper into these files.
