Below is the output of the commands you requested. The naviagent
binary is 32-bit. The RPM filename has "noarch" for the architecture,
and there is no way to specify the Linux distribution or architecture
on the download page, so EMC must be doing the "one size fits all"
thing.

So you should modify $LD_LIBRARY_PATH to use the older libpthread.so,
the one from the compat-glibc package.
The output of the command below should indicate that libpthread.so.0
is taken from the /usr/lib/i386-redhat-linux3E/lib, instead of using
/lib/tls/libpthread.so.0 :
% LD_LIBRARY_PATH=/usr/lib/i386-redhat-linux3E/lib ldd
/opt/Navisphere/bin/naviagent [...] libpthread.so.0 =>
/usr/lib/i386-redhat-linux3E/lib/libpthread.so.0
[...]
If this is case, you just have to write a shell wrapper script or a
shell alias to call naviagent, something like:
% chmod +x /usr/local/bin/naviagent
% cat /usr/local/bin/naviagent
#! /bin/sh
LD_LIBRARY_PATH=/usr/lib/i386-redhat-linux3E/lib
/opt/Navisphere/bin/naviagent $@
Then modify $PATH in order to call it first:
% which naviagent
/usr/local/bin/naviagent
Try so see if it's working.
You can also take a look in ld.so(8) man page and the LD_PRELOAD
environment variable if it's still no working.

Pierre,
I tried your suggestions with no luck. Whe I specify LD_LIBRARY_PATH, it
still pulls libpthread.so.0 from the /lib/tls:
ldd /opt/Navisphere/bin/naviagent

When that didn't work, I took a look at all the libpthread files on my

Nothing looks out of place or unusual. I took your advice and read the
ld.so man page. I used the LD_DEBUG variable to get full debugging
output:
LD_DEBUG=all ldd /opt/Navisphere/bin/naviagent 2>/root/ld.debug.log
linux-gate.so.1 => (0xffffe000)
libnsl.so.1 => /lib/libnsl.so.1 (0xf7fb7000)
libdl.so.2 => /lib/libdl.so.2 (0x00495000)
libm.so.6 => /lib/tls/libm.so.6 (0x0049b000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x004ca000)
libc.so.6 => /lib/tls/libc.so.6 (0x00368000)
/lib/ld-linux.so.2 (0x0034f000)
The debug log is pretty big, so I attached it as a file. I looked
through it, but nothing looked unusual to me. Could be that I don't know
what to look for.
Any other ideas/suggestions?
almost none ... it's really strange that the libpthread.so.0 used comes
from /lib/tls and not from /usr/lib/i386-redhat-linux3E/ .
* try to play with LD_ASSUME_KERNEL=2.2.5 or LD_ASSUME_KERNEL=2.4.7
perhaps ? It's semi-documented here:
http://article.gmane.org/gmane.linux.centos.general/11770
and here: http://people.redhat.com/drepper/assumekernel.html
I've also some specialized software here (chipit) that has this sentence
in their installation notes:
--------------------------------------------------------------------------------
4) On Linux systems that by default use the new NPTL POSIX thread
library -- usually systems running a 2.6 kernel, but also some with a
recent 2.4 kernel (2.4.20 or later), e.g. RHEL3 / CentOS 3.x -- the
setup script will define the environment variable LD_ASSUME_KERNEL and
assign it a value of "2.4.7" -- unless it has been set up already by
another script/application.
--------------------------------------------------------------------------------
* Send me privately a copy of your binary (just is case).
* what about the library linux-gate.so.1 ? you have it locally ?
Someone clever has perhaps a clue ?
This is monday, a bad day :-(
