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"

cris-gcc  -melinux -s -symbolic -static -o dropbearmulti dbmulti.o atomicio.o

termcodes.o libtomcrypt/libtomcrypt.a libtommath/libtommath.a -L
/usr/local/cris/lib/gcc-lib/cris/2.96/elinux/ uccrt/*.o

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

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

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


-------------------


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
common-algo.o common-kex.o common-channel.o common-chansession.o termcodes.o

circbuffer.o svr-kex.o svr-algo.o svr-auth.o sshpty.o svr-authpasswd.o
svr-authpubkey.o svr-session.o svr-service.o svr-chansession.o svr-runopts.o
svr-agentfwd.o svr-main.o svr-x11fwd.o svr-tcpfwd.o svr-authpam.o
libtomcrypt/libtomcrypt.a libtommath/libtommath.a  -melinux -s -symbolic
-static -L /usr/local/cris/lib/gcc-lib/cris/2.96/elinux/ uccrt/*.o

Saner again:

Get http://developer.axis.com/download/old/devboard/R1_1_0/devboard-R1_1_0.tgz
And the cris-dist debian package (we're using 1.16-1).

PATH=/usr/local/cris:$PATH

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
them.

PATH=/space/axis/matt/devboard-R1_1_0/devboard/tools:$PATH
(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.
