openssh unix dev - Jul 2000 - Patch to make openssh-2.1.1p3 compile on SunOS 4.1.4

Hi,

For the last few weeks I've been struggling to get openSSL/openSSH compiled
and running under SunOS.

Specfically, openssh-2.1.1p3:
  SSH Version OpenSSH_2.1.1, protocol versions 1.5/2.0.
  Compiled with SSL (0x00905820).

on SunOS 4.1.4.

Happily I can say there is only one small change so I'm not going to even
try to generate all the associated noise you'd expect.

The function 'strtod' in entropy.c requires '#include
<floatingpoint.h>' to
work.  Without it your entropy rate from the prng_cmds file doesn't get
converted into the correcting floating-point number.

The symptom shows up during the make as:
  ...
  $ ./ssh-keygen -b 1024 -f /usr/host/etc/ssh/ssh_host_key -N "" 
  Not enough entropy in RNG

SOLUTION:  (mine :-)  Insert '#include <floatingpoint.h>' into
entropy.c

Note that this is just under SunOS.

Of less importance:  you need to compile with '-liberty' in order to get
the
system call for 'strerror' to work.

In order to do that I need to do the following 'configure' command:

  LIBS="-liberty" ./configure --prefix=/usr/local/openssh
--sysconfdir=\
    /usr/host/etc/ssh --bindir=/usr/host/bin --sbindir=/usr/host/sbin \
    --with-tcp-wrappers --with-xauth --without-pam --with-ssl-dir=\
    /usr/local/openssl --with-cflags=-I/usr/local/include \
    --with-ldflags=-L/usr/local/lib

---

Finally, is there some way to turn of the debugging compile option from the
configure line?  The only 'easy' way I could find was to edit the
'config.cache' and change
  ac_cv_prog_cc_g=${ac_cv_prog_cc_g='yes'}
to
  ac_cv_prog_cc_g=${ac_cv_prog_cc_g='no'}

Just curious.

Hope this is useful.
G.H.A.

Configure now detects the presence of this and will include it if 
necessary.

Isn't libiberty built and installed as part of some of the GNU 
packages? 

Does your libc define sys_errlist? We should be able to use it in
a replacement.

CFLAGS="" ./configure doesn't work?
