[elephant-devel] trouble getting going (with open-store, ...)

[Red Daly]

Thank you for the quick and helpful response :).

With your corrections, all tests passed and I seem to be able to open a
functioning store!  However, life is not perfect yet.  The main problem
I seem to be facing right now is when I attempt to load elephant using
my slime environment (when calling (asdf:operate
'asdf:load-op :ele-bdb)).  For some reason, I lose my lisp connection.
A sample transcript of a common slime session can be found here:
http://paste.lisp.org/display/27406

This is the point of failure of a similar session:
(let ((store-spec '(:BDB "store")))
   (ele:open-store store-spec))
; loading system definition from
; /home/red/code/edufacebook/elephant-0.6.0/ele-bdb.asd into
; #<PACKAGE "ASDF1189">
; registering #<SYSTEM ELE-BDB {B6DF6B9}> as ELE-BDB
---
Lisp connection closed unexpectedly: exited abnormally with code 256

This is perhaps a slime/sbcl/other bug, but so far I haven't seen
anything like it, and since slime is so popular (and useful) perhaps
others have seen this bug or know what to do about it.

In the raw sbcl REPL I do not seem to have a problem, but only when I
attempt to load ele-bdb.

If you would like, I can post the problems I had with CMUCL when I have
more time.  (off the top of my head, I remember package locking problems
and also a problem loading cl-base64).  at the moment I am more
concerned with getting a working system in SBCL with Slime, but I would
like to help make elephant better however I can.
