推荐答案

使用 --whole-archive 标志:

gcc -shared -o libsrp.so -Wl,--whole-archive -lsrp -Wl,--no-whole-archive

来自 ld 手册页(我的重点):

--整体存档对于 --whole-archive 选项后命令行中提到的每个存档，将存档中的每个目标文件都包含在链接中，而不是在存档中搜索所需的目标文件.这通常用于将存档文件转换为共享库，强制将每个对象都包含在生成的共享库中.此选项可以多次使用.

--whole-archive For each archive mentioned on the command line after the --whole-archive option, include every object file in the archive in the link, rather than searching the archive for the required object files. This is normally used to turn an archive file into a shared library, forcing every object to be included in the resulting shared library. This option may be used more than once.
