Good to know that you agree with that :) I will look into fixing up that patch this week. Did anything ever happen with this? Coincidentally, I had the time to look into this today (Christmas holidays :). I have completely reworked the patch, actually fully removing the CoreText calls. This removes the need for a nasty configure thing and HAVE_CORETEXT macros for now. Both Tiger and (Snow) Leopard now use ATS calls in the ATSUI backend. I have just pushed the commit to Pango's master branch: http://git.gnome.org/browse/pango/commit/?id=0f06d7758bc37a4942342d2c17a88944cbc88adb Of course it is known that ATS has been deprecated in Mac OS Leopard. Just adding some CoreText calls to the ATSUI backend is not the proper way to solve this. (Since all other parts still do deprecated ATS calls). In the very near feature, we will have to write a proper CoreText backend for Pango from scratch. But for now, usage of ATS will suffice on all platforms. regards, -kris. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

They didn't really port the backend to CoreText. It is still using the ATSUI API and they changed two function calls. I have an easy patch that puts the old calls (which were removed) back and then it builds and works fine on Tiger. I will try to clean this patch up and push it soon (and also test it on Leopard, which I was not able to do before). The real challenge will be to write a proper, real, CoreText backend for Pango. I might tackle that in the future. True, switch would have been a better term... ISTM that a configure option and a macro that selects either the ATSUI or CoreText function is the way to go, so that Pango will build both for Tiger and x86_64. Cairo needs the same treatment; right now they just skip the ATSUI functions when building in 64-bit.
