<p>
|

To examine a busybox binary with an eye to saving bytes, build an
|
||||
optimized debug version and run the "nm" command against it, like so:
|
||||
</p>
|
||||
<p>
|
||||
make clean && make STRIPCMD=/bin/true && nm --size-sort busybox
|
||||
</p>
|
||||
<p>
|
||||
This gives a list of symbols and the amount of space allocated for
|
||||
each one, sorted by size. (Note: do not enable CONFIG_DEBUG for this,
|
||||
as that disables compiler optimization which is great for running gdb
|
||||
but misleading when trying to figure out how much space each component
|
||||
is really using under normal circumstances.)
|
||||
The busybox Makefile can generate a report of how much space is actually
|
||||
being used by each function and variable. Run "<b>make sizes</b>" (preferably
|
||||
with CONFIG_DEBUG off) to get a list of symbols and the amount of
|
||||
space allocated for each one, sorted by size.
