busybox/Makefile
Eric Andersen 25f2703015 This is the initial checkin of Larry Doolittle's hush.c, using his
April 25, 2001 snapshot, adjusted a bit by me so it has cmdedit support.

This checkin also removes sh.c.  In the future sh.c will be a symlink to
your shell of choice.  For now, this symlink will default to pointing to
lash.c (as in the past).  If you change the symlink to point to hush.c,
then thats what you will get.  This symlink business is a temporary situation,
which will be cleaned up Real Soon Now(tm).

# With a modern GNU make(1) (highly recommended, that's what all the
# developers use), all of the following configuration values can be
# overridden at the command line. For example:
# make CROSS=powerpc-linux- BB_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
# If you want to add some simple compiler switches (like -march=i686),
# especially from the command line, use this instead of CFLAGS directly.
# For optimization overrides, it's better still to set OPTIMIZATION.

# Leave this set to `false' for production use.

# Do not enable this for production builds...
DODEBUG = false
# Setting this to `true' will cause busybox to directly use the system's
# password and group functions. Assuming you use GNU libc, when this is
# `true', you will need to install the /etc/nsswitch.conf configuration file
# and the required libnss_* libraries. This generally makes your embedded
# system quite a bit larger... If you leave this off, busybox will directly
# use the /etc/password, /etc/group files (and your system will be smaller, and
# I will get fewer emails asking about how glibc NSS works). Enabling this adds
# just 1.4k to the binary size (which is a _lot_ less then glibc NSS costs),
# Most people will want to leave this set to false.
USE_SYSTEM_PWD_GRP = true
# This enables compiling with dmalloc ( http://dmalloc.com/ )
# which is an excellent public domain mem leak and malloc problem
# detector. To enable dmalloc, before running busybox you will
# want to first set up your environment.
# eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
# Do not enable this for production builds...

# If you want large file summit support, turn this on.
# This has no effect if you don't have a kernel with lfs
# support, and a system with libc-2.1.3 or later.
# Some of the programs that can benefit from lfs support
# are dd, gzip, mount, tar, and mkfs_minix.
# LFS allows you to use the above programs for files
# larger than 2GB!

# We need to set APPLET_SOURCES to something like
# $(shell busybox.sh Config.h)
# but in a manner that works with VPATH and BB_SRC_DIR.
# Possible ways to approach this:
#
# 1. Explicitly search through .:$(VPATH) for busybox.sh and config.h,
# then $(shell $(BUSYBOX_SH) $(CONFIG_H) $(BB_SRC_DIR))
#
# 2. Explicity search through .:$(VPATH) for slist.mk,
# then $(shell $(MAKE) -f $(SLIST_MK) VPATH=$(VPATH) BB_SRC_DIR=$(BB_SRC_DIR))
#
# 3. Create slist.mk in this directory, with commands embedded in
# a $(shell ...) command, and $(MAKE) it immediately.
#
# 4. Use a real rule within this makefile to create a file that sets
# APPLET_SOURCE_LIST, then include that file. Has complications
# with the first trip through the makefile (before processing the
# include) trying to do too much, and a spurious warning the first
# time make is run.
#
# This is option 3:
#
#APPLET_SOURCES = $(shell \
# echo -e 'all: busybox.sh Config.h\n\t@ $$(SHELL) $$^ $$(BB_SRC_DIR)' >slist.mk; \
# make -f slist.mk VPATH=$(VPATH) BB_SRC_DIR=$(BB_SRC_DIR) \
