hello all,

Motivated by all the good things I saw about gtk on os x these days and repulsed by all the statistics I should be doing for my real life work, I gave a try at compiling inkscape with GTK native using MacPorts (so not using the all in one build script that Michael cook up a little while ago).

MacPorts is the OS X equivalent of apt-get, portage, yum or whatever. We use it to provide Inkscape dependencies currently and it is very convenient to compile Inkscape that way. It is both easy (all second level dependencies are managed by macports) and economic (the libraries I compile for inkscape can be used in other projects). I wanted to keep this ease of use and to leverage the work of others, so I wanted to keep using MacPorts.

The steps:

1- MacPorts includes native versions of gtk and cairo, which can be installed with: port install cairo +quartz gtk2 +quartz (gentoo and bsd users will recognize the "variants" switches added to both packages). there is a small bug in gtk which is known and solved by the patches in this ticket, at MacPorts: http://trac.macports.org/projects/macports/ticket/12566 hopefully they will commit this soon... but the bug report is quite old already.

2- Other libraries compiled against gtk or cairo need to be recompiled to use these new variants. namely: port -f uninstall cairomm gtkmm pango port install cairomm gtkmm pango this could possibly be solved by a clever use of upgrade when compiling gtk2 and cairo but I did not bother (I should have though...)

3- then compile inkscape from fresh make distsclean cd packaging/macosx/ change the compilation options to remove "--enable-osx-app" for now and then update, configure, build and install: ./osx-build-sh u a c b i compilation goes smoothly for latest svn... great great great!!! Now, on for the hard part:

4- run inkscape cd ../../Build/bin/ ./inkscape and here: (inkscape:20759): Pango-WARNING **: Error loading GDEF table 85

Emergency save activated! Emergency save completed. Inkscape will close now. If you can reproduce this crash, please file a bug at www.inkscape.org with a detailed description of the steps leading to the crash, so we can fix it.

(inkscape:20759): GLib-WARNING **: g_main_loop_run(): called recursively from within a source's check() or prepare() member, iteration not possible.

Aaaargh.

Anyway, the good points are that it is now quite easy to get GTK native in our regular building system and that Inkscape builds and links fine against it!

Now, about the crash, it may well be that my system is still kind of dirty (I have some native things but the rest of the libraries are the old ones) but I think it is more likely a bug in cairo +quartz. I'll be happy to try to track it down and see if it is fixable in Inkscape or if this needs to be solved ahead. From the gdb backtrace below it seems to involve pango_cairo_renderer_draw_glyph. If that rings a bell to anyone I'll be glad to know what you think or provide more info where it is needed. I will also probably try to reinstall a separate macports hierarchy this week end and reinstall everything with gtk native there, to be sure the dependencies are clean. We'll see.

Anyway, even if I only saw a blank window instead of Inkscape UI, I was still quite happy to see it without the X11 icon in the dock!!

Cheers,
