| # With a modern GNU make(1) (highly recommended, that's what all the |

| # 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. |

| |
| # 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. |

| # This enables compiling with dmalloc ( http://dmalloc.com/ ) |
| # which is an excellent public domain mem leak and malloc problem |

| # want to first set up your environment. |

| # 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; \ |
