Subject: [cl-gd-devel] cl-gd on 64 bit Lisp with do-pixel
Message-ID: <fd2982320802110409v3576504bocf6ee39bfd3481ca@mail.gmail.com>

Hi,

I'm trying to use cl-gd on a 64 bit platform and I have a problem with
DO-PIXELS applied to a truecolor image:

(with-image-from-file (image "/home/hans/affe.jpg")
  (do-pixels (image)
    (format t "~A~%" (raw-pixel))))

fails with a memory access violation error, both on openmcl and on
sbcl on FreeBSD/amd64.  Do others see this, too, on 64 bit Lisps?  I
want to rule out that it is a problem with gd on FreeBSD or the fact
that I am using CFFI-UFFI-COMPAT.

I have only quickly looked at cl-gd/misc.lisp and I saw that it uses
:int as type specifier where I think a more specific data type like
uint32 or some such would have been required.  But it could all be me.

So, does anyone here run cl-gd on a 64 bit Lisp?

Thanks,
Hans

Hi,

sure enough, my problem was not rooted in CL-GD, but rather in the
fact that I was using CFFI-UFFI-COMPAT.  I'll try to avoid that now!

I'm still having problems with true color images on my 64 bit Lisps,
so if anyone with experience in that direction is reading, please
speak up! :)

Thanks,
Hans

For the records:  cl-gd just works fine on 64 bit Lisps (SBCL and CCL)
if one uses UFFI, not CFFI-UFFI-COMPAT.  UFFI works fine on CCL with a
small patch to support pointers to pointers.  If you read this in the
archive and have problems compiling cl-gd with UFFI on CCL, contact
me.

FWIW, I haven't tested this but I suspect the problem with 64-bit SBCL
and CFFI relates to a bogus declaration wrt pointer types which has been
fixed for a while in a separate branch and, as of a few minutes ago,
pushed to the main tree.
