# General notes:
#
# A number of Make variables are used to generate the crunchgen config file.
#
#  CRUNCH_SRCDIRS: lists directories to search for included programs
#  CRUNCH_PROGS:  lists programs to be included
#  CRUNCH_LIBS:  libraries to link with
#  CRUNCH_BUILDOPTS: generic build options to be added to every program
#
# Special options can be specified for individual programs
#  CRUNCH_SRCDIR_$(P): base source directory for program $(P)
#  CRUNCH_BUILDOPTS_$(P): additional build options for $(P)
#  CRUNCH_ALIAS_$(P): additional names to be used for $(P)
#
# By default, any name appearing in CRUNCH_PROGS or CRUNCH_ALIAS_${P}
# will be used to generate a hard link to the resulting binary.
# Specific links can be suppressed by setting
# CRUNCH_SUPPRESS_LINK_$(NAME) to 1.
#

# Define Makefile variable RESCUE
CRUNCH_BUILDOPTS+= -DRESCUE
# Define compile-time RESCUE symbol when compiling components
CRUNCH_BUILDOPTS+= CRUNCH_CFLAGS=-DRESCUE

# An experiment that failed: try overriding bsd.lib.mk and bsd.prog.mk
# rather than incorporating rescue-specific logic into standard files.
#MAKEFLAGS= -m ${.CURDIR} ${.MAKEFLAGS}

# Hackery:  'librescue' exists merely as a tool for appropriately
# recompiling specific library entries.  We _know_ they're needed, and
# regular archive searching creates ugly library ordering problems.
# Easiest fix: tell the linker to include them into the executable
# first, so they are guaranteed to override the regular lib entries.
# Note that if 'librescue' hasn't been compiled, we'll just get the
# regular lib entries from libc and friends.
CRUNCH_LIBS+= ${.OBJDIR}/../librescue/*.o
