- 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: -

-

- make clean && make STRIPCMD=/bin/true && nm --size-sort busybox -

-

- 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 "make sizes" (preferably + with CONFIG_DEBUG off) to get a list of symbols and the amount of + space allocated for each one, sorted by size.
