[PATCH 4/4] autofs-5.1.8 - configure: LDAP function checks ignore implicit declarations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Thomas Reim <reimth@xxxxxxxxx>

Wrong CFLAGS: gcc handles implicit function declaration as warning with current
flag settings. Missing functions in libldap will not be identified.
