I would like to build openssh

64bit on solaris 10 U4 on a dual core opteron system

My issue is that at the link phase:

SunStudio/12/SUNWspro/bin/cc -V -o ssh ssh.o readconf.o clientloop.o
sshtty.o sshconnect.o sshconnect1.o sshconnect2.o -L. -Lopenbsd-
compat/ -L/usr/sfw/lib/amd64 -R/usr/sfw/lib/amd64 -L/usr/lib -R/usr/
lib -L/usr/sfw/lib/amd64 -lssh -lopenbsd-compat -lresolv -lcrypto -lrt
-lz -lsocket -lnsl
cc: Sun C 5.9 SunOS_i386 Patch 124868-01 2007/07/12
ld: Software Generation Utilities - Solaris Link Editors: 5.10-1.489
ld: fatal: file ssh.o: wrong ELF class: ELFCLASS64
ld: fatal: File processing errors. No output written to ssh

I need the SunStudio compilers as gcc on the system is 32 bit and will
nor build 64 bit binaries. S far as I can tell

ssh.o is a 64 bit object

file ssh.o
ssh.o: ELF 64-bit LSB relocatable AMD64 Version 1

so I am not sure what this is telling me. Has anyone succesfully built
openssh in 64bit mode on solaris?

(1) why do you include 32 bit library paths with -L/-R?
(2) why do you include /usr/lib at all?
(3) where is the -m64 flag for cc?

SunStudio and gcc with both happily build 64 bit object files if getting
passed the right flags.

Why do you want to build openssh when the system *comes* with
openssh?

It's possible that ld is calling in a 32-bit module from a library. Try
doing it with -m64 to force 64-bit mode.

because sun solaris delivers a little bit backdated version of ssh (U4
equivalent to something like 3.x i assume) , e.g. it have still no
Timeout Parameter or ControlMaster, which can speed up sequential
scripts a lot.
