Re: to reduce footprint

[Lin George]

Thanks Danny. I think -s will strip some symbols in the binaries after reading 
related part of the manual. But I have not found an answer to my concern that 
if I strip something from the binary, whether some functions will be lost in 
the binaries? I have this concern is because I think function and footprint are 
a balanced pair. If I strip (remove) anything, I may lose some functions. Could 
you kindly clarify please?


regards,
George

I'm not an expert in the field, but I know there might be a few linker flags
that can help you. For instance, ld (on Linux) has the '-s' or '-S' option
(see the ld manual for more info). I also suggest you take a look at
'strip'; that command is probably what you're looking for. Once again, the
manual can tell you far more than I can ;-)

Hope this helps,
Danny
