如何打印 ld(linker) 搜索路径 [英] How to print the ld(linker) search path

问题描述

按搜索顺序打印ld 查找的搜索路径的方法是什么.

What is the way to print the search paths that in looked by ld in the order it searches.

推荐答案

您可以通过执行以下命令来做到这一点:

You can do this by executing the following command:

ld --verbose | grep SEARCH_DIR | tr -s ' ;' \012

gcc 将一些额外的 -L 路径传递给链接器，您可以使用以下命令列出这些路径:

gcc passes a few extra -L paths to the linker, which you can list with the following command:

gcc -print-search-dirs | sed '/^lib/b 1;d;:1;s,/[^/.][^/]*/../,/,;t 1;s,:[^=]*=,:;,;s,;,;  ,g' | tr ; \012

建议使用 ld.so.conf 和 ldconfig 的答案不正确，因为它们指的是运行时动态链接器搜索的路径(即每当程序执行时)，这与 <搜索的路径不同strong>ld(即当程序被链接时).

The answers suggesting to use ld.so.conf and ldconfig are not correct because they refer to the paths searched by the runtime dynamic linker (i.e. whenever a program is executed), which is not the same as the path searched by ld (i.e. whenever a program is linked).
