[fetter-devel] Verrazano / CFFI attempt - FreeTDS

[Brad Anderson]

Gents,

I'm attempting to wrap the FreeTDS 0.63 library in CFFI
(http://freetds.org) and running into some problems.

I've pulled cffi-luis tarball from 2005-12-15 and verrazano cvsroot
tarball from 2005-12-19.  I'm also using SBCL 0.9.6 on Gentoo Linux.
All of the prerequisites are installed, including PARSE-NUMBER (Rayiner,
see other email to you yesterday).


Here are my files:

% cat freetds.db-lib.binding
(defbinding "freetds.db-lib"
  (nicknames "dblib")
  (flags "")
  (include "sqldb.h" "sqlfront.h")
  (export "")
  (override ""))

% cat generate.lisp
(require 'asdf)
(require 'cffi)

(asdf:operate 'asdf:load-op 'verrazano)
(verrazano:create-binding
 (verrazano:setup-build "gccxml"
                        (make-pathname :device "/"
                                       :directory "/tmp"))
 "freetds.db-lib.binding"
 "freetds.db-lib.lisp"
 :cffi-backend
 t)




Here's the debug output:

Here's the resulting lisp file:

% cat freetds.db-lib.lisp
(defpackage "FREETDS.DB-LIB" (:use #:CFFI) (:nicknames "DBLIB") (:export))

(in-package "FREETDS.DB-LIB")
(asdf:operate 'asdf:load-op 'verrazano-support)
(cl:progn)



So something isn't working, and I lack both Lisp skills as well as C
development experience.  It's a great combination, I know ;) but I was
hoping to sneak by for a little while with your tools.  Is this a
problem w/ C vs. C++ as the source?

Any help would be appreciated.

Cheers,
Brad
