In order to know which dynamic libraries a particular binary is using, just type ldd. For example with busybox: sh-3.00# ldd /bin/busybox /bin/busybox: is setuid libcrypt.so.0 => /lib/libcrypt.so.0 (0x2aaed000) libm.so.0 => /lib/libm.so.0 (0x2ab41000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x2ab9c000) libc.so.0 => /lib/libc.so.0 (0x2abeb000) ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x2aaa8000) Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com
