Subject: ldconfig is statically linked or dynamiclly linked
Date: Thu, 1 Sep 2022 17:41:39 +0800	[thread overview]
Message-ID: <3f822786-189c-1c45-9415-be3f1abe916b@gmail.com> (raw)

Hi all:

    I am confused when exec file ldconfig and ldd ldconfig on CentOS 8(glibc-2.28):

# which ldconfig
/usr/sbin/ldconfig
# file /usr/sbin/ldconfig
/usr/sbin/ldconfig: ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, for GNU/Linux 3.2.0, BuildID[sha1]=90ddd9a3e194fb2ec4edd5184d9fca4df45af636, not stripped
# ldd /usr/sbin/ldconfig
    statically linked


So ldconfig is dynamiclly linked or statically linked?


I lookup elf/Makefile:

ifeq (yes,$(use-ldconfig))
ifeq (yes,$(build-shared))
others-static   += ldconfig
others          += ldconfig
install-rootsbin += ldconfig


I think ldconfig may be statically linked, and can ldconfig be only statically linked?
