Hello Elliott & Jan,<br>
<br>
ty a lot for the DLLs - especially the libberkeley-db.dll saved me may<br>
be hours today looking in the gcc & dlltool docs...<br></blockquote><div><br>No problem :-)<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
But - now it seems LWW can talk to the DLLs & DB, but:<br>
<br>
1. in the OPEN-CONTROLLER (in the bdb-controller.lisp) I get some new<br>
errors now :<br>
- (db-env-set-max-locks env max-locks) gives error 22 - invalid argument..<br>
- (db-env-set-max-transactions env max-transactions) - the same<br></blockquote><div><br>Aha! This is the same error I'm getting in SBCL.<br><br>I'll try debugging further tonight.<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
>From what I see in the code - the invocation uses meaningfull<br>
arguments, putting some debug statements tells that at least on the<br>
Lisp side we have the right constant-values which correspond with the<br>
"db.h"-declarations.<br>
<br>
So - I'm a step further with your help, but still can't even open a<br>
database. I hope - there is a solution. Of course, I could try to make<br>
the binding using directly the LW FFI, but that would be sad private<br>
solution or unnesessery source fragmentation when there is UFFI/CFFI<br>
as a base.<br>
<br>
(Now I use BDB 4.7.25, the newest UFFI in front of CFFI and the DLLs I<br>
receved today)<br>
<br>
If there is a chance for help - I would be very happy.<br>
