linux - 动态库查找ld的规则是什么？

Question

Linux 将链接器时搜索路径和运行时搜索路径分开。

对于运行时搜索路径，我在其man page (8 ld.so) 中找到了ld.so 的规则。 :

1. DT_RPATH
2. 环境 LD_LIBRARY_PATH
3. DT_RUNPATH
4. ld.so.cache
5. /lib,/usr/lib

但是对于链接器时搜索路径，ld 运气不好 :(

Man page for ld (1 ld)说，除了 -L 选项:

The default set of paths searched (without being specified with -L) depends on which emulation mode ld is using, and in some cases also on how it was configured.

The paths can also be specified in a link script with the "SEARCH_DIR" command. Directories specified this way are searched at the point in which the linker script appears in the command line.

取决于仿真模式的“默认路径集”是否表示“SEARCH_DIR”？

Answer 1

misssprite , 要查找特定 ELF 仿真的链接器搜索路径，只需运行 ld -m<emulation> --verbose | grep SEARCH_DIR
