AC_CHECK_LIB([ldap], [ldap_initialize], [], [...]) should not append -lldap to
|
|
|
ebd0cbd |
LIBS variable because third AC_CHECK_LIB arugment is defined and
|
|
|
ebd0cbd |
empty.
|
|
|
ebd0cbd |
|
|
|
ebd0cbd |
But broken autoconf-2.69-21.fc23 thinks empty is undefined and
|
|
|
ebd0cbd |
defaults to implicit if-found action. That results into linking all
|
|
|
ebd0cbd |
executables to ldap library and that is unnecessary.
