From bb2fd67d0bfe16441d4b1d2e6ece83b04955b379 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 14 Aug 2015 08:50:00 +0200 Subject: [PATCH] Makefile: add missing libraries to LDLIBS Static build with CONFIG_PAM fails on Debian Jessie due to undefined references to libdl and libaudit. Static build without pam, but with libcrypt required fails as well due to undefined references to libpthread. Fix these two cases by adding the missing libraries to LDLIBS when appropriate.
