Hi Alexandre, What platform are you building on? Some platforms seem to end up with larger code than x86 - not entirely sure if it’s the architecture or compiler issues. Compiler flags can also make a big difference, were you using the suggested ones? I know -flto makes a difference with avr-gcc microcontroller code, it might help for Dropbear too.
You could grab the Dropbear 0.44 souce tree and see how it compares - I suspect it has got a bit larger, though not that much. ECDSA and the newer sha2 modes are the big things that come to mind and can be disabled in options.h Cheers, Matt > On Mon 16/2/2015, at 10:24 pm, Alexandre Kaskasoli > <alexkaskas...@hotmail.com> wrote: > > Hello Matt, > > There is a link on the homepage on compiling dropbear to about 110kb but the > post is from 2004. > > I've been playing around with options.h and managed to get the dropbear > server to about 195kb. > > I realise a lot of things have been added and changed in the last decade and > I'm happy with the size but was wondering if we could reach any smaller now? >
