# $NetBSD: Makefile.readline,v 1.4 2001/05/22 16:46:37 jlam Exp $
#
# This Makefile fragment is included by packages that use readline().
#
# If readline() is not present in the base system through libedit, then a
# dependency on devel/readline is added, the appropriate headers are linked
# into ${WRKINCDIR} (${WRKSRC}/include), and the appropriate libraries are
# linked into ${WRKLIBDIR} (${WRKSRC}/lib).
#
# To use this Makefile fragment, simply:
#
# (1) Optionally define USE_GNU_READLINE to force use of GNU readline.
# (2) Optionally define READLINE_REQD to the version of GNU readline desired.
# (3) Include this Makefile fragment in the package Makefile,
# (4) Optionally define WRKINCDIR and WRKLIBDIR,
# (5) Add link-readline-headers and link-readline-libs to the prerequisite
# targets for pre-configure,
# (6) Add ${WRKINCDIR} to the front of the C preprocessor's header search
# path, and
# (7) Add ${WRKLIBDIR} 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.
