# This Makefile fragment is included by package Makefiles and
|
|
# buildlink3.mk files for the packages that need a thread-safe
|
|
# DNS resolver.
|
|
#
|
|
# It defines the variables RESOLV_LDFLAGS and RESOLV_LIBS,
|
|
# which are also exported into the CONFIGURE_ENV and MAKE_ENV environments.
|
|
#
|
|
# Package-settable variables:
|
|
#
|
|
# RESOLV_AUTO_VARS
|
|
# When set to "yes", the necessary flags are added automatically
|
|
# to LDFLAGS and friends.
|

# Default: no

# Keywords: resolv
