#
# OS/161 build environment: build a program
#
# Usage:
#    TOP=../..
#    .include "$(TOP)/mk/os161.config.mk"
#    [defs go here]
#    .include "$(TOP)/mk/os161.prog.mk"
#    [any extra rules go here]
#
# Variables controlling this file:
#
# PROG				Name of program to generate.
# SRCS				.c and .S files to compile.
#
# CFLAGS			Compile flags.
# LDFLAGS			Link flags.
# LIBS				Libraries to link with.
# LIBDEPS			Full paths of LIBS for depending on.
#
# BINDIR			Directory under $(OSTREE) to install into,
#                               e.g. /bin. Should have a leading slash.
#
# Note that individual program makefiles should only *append* to
# CFLAGS, LDFLAGS, LIBS, and LIBDEPS, not assign them. Otherwise stuff
# set by os161.config.mk will get lost and bad things will happen.

# Install: we can install into either $(INSTALLTOP) or $(OSTREE).
# When building the whole system, we always install into the staging
# area. However, if you're working on a particular program it is
# usually convenient to be able to install it directly to $(OSTREE)
# instead of doing a complete top-level install.
#
# Note that we make a hard link instead of a copy by default to reduce
# overhead.
