# $NetBSD: buildlink.mk,v 1.18 2002/08/07 06:10:34 jlam Exp $
#
# This Makefile fragment is included by packages that use readline().
#
# To use this Makefile fragment, simply:
#
# (1) Optionally define USE_GNU_READLINE to force use of GNU readline.
# (2) Optionally define BUILDLINK_DEPENDS.readline to the dependency pattern
# for the version of GNU readline desired.
# (3) Add ${BUILDLINK_DIR}/include to the front of the C preprocessor's header
# search path, and
# (4) Add ${BUILDLINK_DIR}/lib to the front of the linker's library search
# path.
#
# NOTE: You may need to do some more work to get libedit recognized over
# libreadline, especially by GNU configure scripts.
