[elephant-devel] Trouble loading libdb-4.5.so (SBCL, FreeBSD @ amd64)

[Linus Nordberg]

Hi,

I'm trying to get Elephant running with SBCL-1.0.16 built with threading
support, FreeBSD-6.2 on amd64, db-4.5 from ports.

I'm really too clueless to even know where to start with this.  I
suppose it might well be an SBCL or libdb issue but I thought I'd rather
check with you first.


The same problem is easily reproduced with (require 'ele-bdb) which BTW
shows that site/elephant/src/memutil/libmemutil.so is successfully
loaded (uffi-1.6.0).

The executive summary of SBCL's run-tests.sh goes like this:
--8<---------------cut here---------------start------------->8---
 Expected failure:    callback.impure.lisp / UNDERFLOW-DETECTION
 Invalid exit status: clos-cache.impure.lisp

FWIW, the threads failure looks like this:
--8<---------------cut here---------------start------------->8---
// Running /usr/local/ports/basejail/usr/ports/lang/sbcl/work/sbcl-1.0.16/tests/threads.test.sh

Please let me know if there's any more information that I should supply.
Thanks.
