+TARGET_OS := linux
# 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=$HOME/busybox PREFIX=/mnt/app
+# make CROSS=powerpc-linux- CONFIG_SRC_DIR=$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.
# Set the following to `true' to make a debuggable build.
# Leave this set to `false' for production use.
-# eg: `make DODEBUG=true tests'
-# 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.

-# We need to set APPLET_SOURCES to something like

-# 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.
-#

-#
-#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) \
-#)
