#
#	History:
#
#	Modified by cmetz for OPIE 2.4. Add libmissing to include header path.
#		Renamed realclean to distclean. Added opieauto rules. Made
#		system program install more tolerant of non-existent files.
#	Modified by cmetz for OPIE 2.31. Moved logwtmp.o into libopie.
#	Modified by cmetz for OPIE 2.3. Removed manual config -- it's
#		Autoconf or bust. Replaced user configuration options
#		with options.h. Eliminated unused variables. Pass down
#		$(DEBUG) instead of several other variables to the
#		subdirs. Extended/standard key file support. Added
#		dependencies on subdir files. Made opietest call silent.
#		Removed opie-md4, opie-md5, and key aliases. Removed
#		test target. Make uninstall remove man page aliases.
#	Modified by cmetz for OPIE 2.22. Removed @LIBOBJS@ from MISSING for
#		Autoconf target. Re-ordered LFLAGS because some ld's won't
#		include libmissing properly if it's not at the end.
#       Modified by cmetz for OPIE 2.21. Added getusershell.o to IRIX
#               missing functions.
#       Modified by cmetz for OPIE 2.2. Added NEW_PROMPTS definition.
#               Added MISSING and new flags-passing for libmissing.
#               Quote MISSING or lose. Update TEST target for FTPD
#               variable. Removed line formatting for compile commands
#               since macro expansion confuses the issue anyway.
#               Added targets for opieserv. Added targets for opietest.
#               Removed obselete options.h target. Swapped libmissing
#               and libopie. Updated manual config options. Added more
#               explanatory text. Fixed uses of old SYSV and BSD4_3
#               symbols.
#       Modified at NRL for OPIE 2.2: Renamed LDFLAGS setting to LIBS,
#               renamed LDFLAGS in targets to LFLAGS. Added targets for
#               libopie and libmissing directories. Got rid of PROTOTYPES.
#               Added opiegen. Fixed RANLIB Autoconf target. 
#       Modified at NRL for OPIE 2.11: Fixed fatal mistype of Autoconf.
#	Modified at NRL for OPIE 2.1: Changed targets to reflect source
#		file name changes. Changed explanation and flags for static
#		linking. Changed opieinfo target. Removed WHOAMI. Added
#		Autoconf targets. Changed if conditionals to use test
#               instead of [. Changed SU_DIR to SU to help autoconf.
#               Changed FTPDIR and FTPDNAME to FTPD to help autoconf.
#               Changed HP-UX to HP-UX9 and HP-UX10. Make uninstall
#               target depend on config. HPUX *is* no longer necessary, but
#               something does have to be there. Sub in Autoconf @CC@.
#       Modified at NRL for OPIE 2.04: Re-worded explanation of SU_STAR_CHECK.
#       Modified at NRL for OPIE 2.02: Added SU_STAR_CHECK flag.
#       Modified at NRL for OPIE 2.01: Test target makes opiesu and opielogin 
#               setuid. install target clears that. uninstall target needs to
#               remove the opiekey symlinks. opieinfo target needs to 
#               substitute for $(EXISTS). ifdefs target needs to check for 
#               starting hash. $(LFLAGS) and -o should be at the end of all 
#               link commands to spoon-feed drain bamaged link editors. Added
#               A/UX defaults.
#	Modified heavily at NRL for OPIE 2.0.
#	Written at Bellcore for the S/Key Version 1 software distribution
#		(Makefile).

#============================================================================
# CONFIGURATION PARAMETERS -- CHANGE THESE TO SUIT YOUR MACHINE

# Shell to use for make(1)
# It's usually a good idea to leave this as-is. On some systems, ksh or bash
# may be necessary
SHELL=/bin/sh

# OWNER is the username who should own the OPIE binaries.
# GROUP is the groupname associated with the OPIE binaries.
#
OWNER=0
GROUP=bin

# Where should the OPIE standard and extended databases be stored?
#
# Some sites might want to put this elsewhere. If you want to use an old
# S/Key database, you should create a link from /etc/skeykeys to /etc/opiekeys.
KEY_FILE=/etc/opiekeys

# Are we debugging?
#
# The first line will build a normal version of OPIE. You should use it.
#
# The second is for brave souls porting OPIE to a new system or trying to
# debug it and should definitely NOT be used to build a production copy
# of OPIE. 
#
# The third is the above using nifty heap debugger called "Electric Fence".
DEBUG=-O
#DEBUG=-DDEBUG=1 -g
#DEBUG=-DDEBUG=1 -g -lefence

# These parameters are determined by Autoconf and are probably correct.
# If OPIE doesn't build or work right, try tweaking these.
