|
|
# 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).

#
|
|
# 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) \
