BusyBox

BusyBox


This is about using busybox alone , not under buildroot or uClinux-dist.

You can download the latest snapshot or stable release from busybox.net.

Busybox, .config for cross compile

I used this flags before, (but not now)

EXTRA_CFLAGS_OPTIONS="-D__uClinux__ -Dfork=vfork"

Busybox, Makefile add elf2flt flag



busybox_unstripped: .depend $(LIBBUSYBOX_SONAME) $(BUSYBOX_SRC) $(libraries-y)

$(do_link) $(PROG_CFLAGS) $(PROG_LDFLAGS) $(CFLAGS_COMBINE)

-Wl,-elf2flt="-s 16000" -Wl,-v -Wl,-d 

-o $@ -Wl,--start-group  

$(APPLETS_DEFINE) $(APPLET_SRC) 

$(BUSYBOX_DEFINE) $(BUSYBOX_SRC) $(libraries-y) 

$(LDBUSYBOX) $(LIBRARIES) 

-Wl,--end-group



busybox: busybox_unstripped

$(Q)cp busybox_unstripped busybox

# $(do_strip)



There is an important issue about busybox. It takes more memory on MMU-less arch.

So I moved away from busybox a little. I use stand alone init, sash, and servers from uClinux-dist. I built others utils into busybox. See UClinuxDist
