Subject: [cl-cairo2-devel] Multiple errors
Message-ID: <654935030803200940v50eca8a4ra5bb5583f19e569e@mail.gmail.com>

I'm trying to load and use cl-cairo2 from the SVN repository.  I've
noticed multiple errors, some that I can work around, and some not.  I
am using SBCL on Debian/amd64.

1) Tutorial won't make because of missing hearts.png.
2) In the file xlib, I get a warning:
  Defining a foreign type named ATOM.  This symbol belongs to the
  COMMON-LISP package and that may interfere with other code using
  CFFI.
3) Tutorial example shows create-ps-surface passed fixnums, but it
requires   double-floats.
4) Cannot run (setf *context* (create-context *surface*)) from
example, gives error:
The function FINALIZE is undefined.
   [Condition of type UNDEFINED-FUNCTION]

and it is on 4 that I am stuck; finalize indeed seems to be undefined.

Thanks,
Liam

Hi Liam,

I just saw your message on your blog, somehow your message didn't get
to me, I checked my spam filter but it was not caught by that either.
I will investigate that...

Anyhow, I uploaded a fix to all the cl-cairo2 errors you mentioned.
Please let me know if this works.

Tamas

Hi Tamas,

Thanks for the fixes.  I will investigate when I come back to Cairo.
My interest in Cairo was twofold:  I have an old (but good!)
2d plotting program that is in need of a modern back end, and I have
built up a variety of mathematical drawing functions that use a small
postscript output package I wrote.  On close investigation, I found that
both would require a significant investment of time to port to Cairo.
I will track what's going with Cairo and I hope come back to these
projects soon.

Liam
