Running it:

For normally (just vfork(), no inetd):

./dropbear -F -E 

(add -v for verbose). Note that since it's vforking, only one connection
will reliably work at a time.

For inetd-server mode, which will execv() a new dropbear inetd child each time:

./dropbear -x /path/to/dropbear -F -E

Notes for archiving... this is what you need to build dropbear 0.47.

export PATH=/usr/local/cris:$PATH
export CFLAGS="-melinux -O3 -s -symbolic -D__uClinux__"

./configure --prefix=/mnt/flash/dropbear --disable-zlib --host=cris

make MULTI="1" STATIC="1" PROGRAMS="dropbear dbclient scp"

[ paste the multiline cris-gcc command with `xargs` - MSH ]

There's custom stuff in uccrt/ which should also be archived

Doesn't work quite yet - needs some hacking to get around a buggy


Or for just dropbear without multi:

make STATIC=1

cris-gcc  -o dropbear dbutil.o buffer.o dss.o bignum.o signkey.o rsa.o
random.o queue.o atomicio.o compat.o  fake-rfc2553.o common-session.o packet.o

-static -L /usr/local/cris/lib/gcc-lib/cris/2.96/elinux/ uccrt/*.o


Saner again:

And the cris-dist debian package (we're using 1.16-1).


Build the axis dev env thing with 
"prefix=/space/axis/matt/R1_1_0-prefix ./install"

You'll actually end up with some images which could be flashed, I haven't tried

(includes /usr/local/cris too)

In dropbear dir:
  ./configure CC=gcc_cris CFLAGS="-melinux -muclibc=/space/axis/matt/R1_1_0-prefix -Wall -O2 -DELINUX" --disable-zlib --disable-syslog --host=cris LDFLAGS="-melinux -muclibc=/space/axis/matt/R1_1_0-prefix"

make, it should work.

If you strip it, it won't work. -Os should work.
