Openssh shared library problem
On my system, there is a problem with programs spawned from sshd and
shared library paths. This is most easily replicated by simply
trying to scp a file to the debian-interix machine:
--
$> scp <file> administrator@debian:/tmp
scp: error in loading shared libraries
libc.so.3.5: cannot open shared object file: No such file or directory
lost connection
--
(Using bash as your shell also causes this problem BTW)
It seems that the primary method of setting these paths (because
there is no ld.so.conf?) is making a system wide setting for
LD_LIBRARY_PATH=""usr/lib/x86:/usr/X11R6/lib". Because sshd doesn't
use pam or read /etc/environment, I thought the easiest way to fix
this would be to add LD_LIBRARY_PATH to the Windows environment
variables, as most of the other variables for SUA are populated
there.
However this variable isn't passed to sshd's children AFAICT because
of this line:
--openssh-4.7p1/session.c line 1064--
[in do_setup_env() ]
/* these are the interix directory
variables... */
"INTERIX_ROOT",
"INTERIX_ROOT_WIN",
"SFUDIR",
"SFUDIR_WIN",
"SUA_ROOT",
"SUA_ROOT_WIN",
"OPENNT_ROOT",
--> /* LD_LIBRARY_PATH required? */
NULL};
--
I verified that if I add LD_LIBRARY_PATH to AcceptEnv in sshd_config
(generally a bad idea), and pass that variable from my ssh client
with SendEnv, the shared library problems go away.
So, I was attempting to comment back the line is session.c and
rebuild, but I wasn't even able to do a build from the deb source
before running into a number of issues, including this header
related one from configure during the dpkg-buildpackage of openssh.

checking dirent.h presence... yes

Before I go in detail any further, is there something obvious that
I'm missing? Nothing has compiled as in the build logs :)
The Windows OS I am using is Windows Server 2003 64 bit R2 SP2, with
all automatic updates applied that are available.
