# -*- Makefile -*-

# Generic makefile for ods2
#
# This tries really hard to be OS-agnostic, because
# otherwise, every little change means updating all
# the os-specific makefiles.
#
# See makefile.<osname>, which normally includes it
#
# If your make doesn't support include, these can be
# specified manually, for example:
#   make CC=gcc "CCFLAGS=-O4 -f" OBJ=.o \
#        PHYSIO=phyunix DEFS=-DUSE_READLINE LDFLAGS=-lreadline
#
# or just combine the files you need with an editor.
#
# ###

# OS-Specific defines
# These variables are available

# Other defines = "-DDEBUG_BUILD" "-D_FILE_OFFSET_BITS=32"
#DEFS =

# Libraries, e.g. -lreadline
#LDLIBS =

# Linker flags
#LDFLAGS =

# Object file suffix
#OBJ = .o

# Executable file suffix

#EXE =

# Physical IO module
#PHYSIO = phyunix

# Extra physical IO headers
#PHYSIOH =

# VHD format options

# This processing is so the kit can contain a generic, up-to-date depends file
# I don't want to require makedepend for people to build from source.
# I do want the file to be accurate when shipped, so auto-maintained.
# makedepend will include all the system library includes, which is not
# helpful for this case.  So the sed processing removes dependencies that
# start with "/" - e.g. /usr/include and friends.
