Hi Everyone,
I have been trying to set up a sage chroot environment. I have
documented the steps I have taken here
http://www.techidiots.net/notes/sage-notebook-chroot-ubuntu
I have the chroot environment created, and sage compiled inside of
it.
If I run sage as my "server" user without dchroot it goes to the sage
prompt properly.
server@wscvsage:~$ /sage_chroot/sage/sage
----------------------------------------------------------------------
| Sage Version 4.7, Release Date:
2011-05-23 |
| Type notebook() for the GUI, and license() for
information. |
----------------------------------------------------------------------
sage: exit
Exiting Sage (CPU time 0m0.06s, Wall time 0m3.64s).
Exiting spawned Gap process.
But is i run sage with "dchroot -d /sage/sage" sage is getting the
following error
server@wscvsage:~$ dchroot -d /sage/sage
I: [sagechroot chroot] Running command: “/sage/sage”

------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred because a *compiled* component of Sage
has a bug
in it and is not properly wrapped with sig_on(), sig_off(). You
might
want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate.

/sage/local/bin/sage-sage: line 300: 1866 Segmentation

Does anyone know what might cause this error? Is it something that is
not in the chroot environment that sage needs to run properly? Is it a
permissions thing?
