From 47601e462c6606f7a711c093fb1b03580b01ee46 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20P=C3=ADsa=C5=99?= Date: Thu, 7 Jan 2016 10:23:24 +0100 Subject: [PATCH] Work around an AC_CHECK_LIB bug in Autoconf MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit AC_CHECK_LIB([ldap], [ldap_initialize], [], [...]) should not append -lldap to LIBS variable because third AC_CHECK_LIB arugment is defined and empty. But broken autoconf-2.69-21.fc23 thinks empty is undefined and defaults to implicit if-found action. That results into linking all executables to ldap library and that is unnecessary.
