I have installed version 4.3.0.1 of Sage at
http://t2nb.math.washington.edu:8000/
This is functional. However, any attempt to import the _hashlib module fails
miserably, as you can see from this published worksheet.
http://t2nb.math.washington.edu:8000/home/pub/0/
Python is not finding the libssl.so.0.9.7 library, which are in /usr/sfw/lib. If
at the command prompt I run
$ export LD_LIBRARY_PATH=/usr/sfw/lib
$./sage
sage: import _hashlib
so it works, with no error message. But any attempt I have made to get Sage to
start at boot time and load the library fails. In order to start the Sage
server, I have a script run at boot time. I don't reproduce it all, but the
important line is this one:
su - sageserv /local-bins/start-sage
That allows this to be started at boot time by root, but run as a user
'sageserv', rather than root which would be very risky.
The script /local-bins/start-sage is:
#!/usr/bin/env bash
LD_LIBRARY_PATH=/usr/sfw/lib
export LD_LIBRARY_PATH
nohup /homes/sageserv/sage-4.3.0.1-Solaris-10-SPARC-sun4u-or-sun4v/sage
/homes/sageserv/notebook.py >> /homes/sageserv/logfile.out&
notebook.py consists of:
-bash-3.00$ cat notebook.py
import sagenb.notebook.notebook_object as n
server_pool=['sa...@localhost']
n.notebook('sage_notebook', port=8000, accounts=True, address='',
server_pool = server_pool, ulimit='-u 1000 -v 1000000 -t 3600',
open_viewer=False, timeout=20*60, secure=False, port_tries=0)
I've tried adding the LD_LIBRARY_PATH to $HOME/.bashrc, $HOME/.profile, but
still sage will not import the _hashlib module, as it can't find the OpenSSL
libraries at runtime.
My next course of action would be to edit local/bin/sage-env, and add it there,
but clearly that is not the ideal way.
It's clear that not only does the OpenSSL library need to be found at compile
time, but also at run time (no surprise there). But what is annoying, is that I
can find no way of getting LD_LIBRARY_PATH to propagate to Sage when started
from a script. It works fine if I start Sage from the command line manually, but
that is no good as a server.
Any ideas how I might solve this? Again, I do not want to mess with crle.
Manually editing sage-env might be one option, but that is not nice.
