Yet another major rework of the BusyBox config system, using the considerably
modified Kbuild system I put into uClibc. With this, there should be no more need to modify Rules.mak since I've moved all the interesting options into the config system. I think I've got everything updated, but you never know, I may have made some mistakes, so watch closely. -Erik

If you want to build BusyBox with large file support, then enable

this option. This will have no effect if your kernel or your C

programs that can benefit from large file support include dd, gzip,

If you want to build BusyBox with a cross compiler, then you

if my cross-compiler is /usr/i386-linux-uclibc/bin/i386-uclibc-gcc

If you want to build a static BusyBox binary, which does not
|

use or require any shared libraries, then enable this option.
|

This will make BusyBox be considerable larger, so you should
|
||||
leave this option false unless you have a good reason (i.e.
|

your target platform does not support shared libraries, or

you are building an initrd which doesn't need anything but

BusyBox, etc).

help
|

Say Y here if you wish to compile BusyBox with debugging symbols.
|
||||
This will allow you to use a debugger to examine BusyBox internals
|
||||
while applets are running. This increases the size of the binary
|
||||
considerably and should only be used when doing development.
|
||||
If you are doing development and want to debug BusyBox, answer Y.

Otherwise, answer N.

config DODMALLOC

bool "Build BusyBox with dmalloc support"

|
||||
help
|
||||
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 properly set your environment, for example:
|
||||
export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
|
||||
The 'debug=' value is generated using the following command
|
||||
dmalloc -p log-stats -p log-non-free -p log-bad-space -p log-elapsed-time \
|
||||
-p check-fence -p check-heap -p check-lists -p check-blank \
|
||||
-p check-funcs -p realloc-copy -p allow-free-null
|
||||
|
||||
This will make BusyBox be considerable larger and run slower, so
|
||||
you should leave this option disabled for production use.

||||
|
||||
config DOEFENCE
|

bool "Build BusyBox with Electric-fence support"

default n

|

help
|
||||
This enables compiling with Electric-fence support. Electric
|
||||
fence is another very useful malloc debugging library which used
|
||||
your computers virtual memory hardware to detect illegal memory
|
||||
accesses. This support will make BusyBox be considerable larger
|
||||
and run slower, so you should leave this option disabled unless
|
||||
you are hunting a hard to find memory problem.
