Re: [Gimp-developer] a GEGL integration strategy
Hi everybody, On Tue, 14 Dec 2004, Øyvind Kolås wrote: The suggestion of starting the integration process of GEGL into gimp with the paint tools came up on irc today. I have put some thought into the order such a conversion might happen in, blend pencil ... The order lists what I think is increasing level of complexity in usage of gegl for the tasks, such a multipurpose gegl tool can probably be implemented and coexist with the rest of the tools while the migration happens. Please forgive me if this question is too basic, but I don't understand in which way the paint tools are going to be implemented as GEGL ops. Will each stroke be a separate node in the graph, or will several strokes be accumulated into one node? Or am I completely misunderstanding things here? What will the graph look like after a stroke with the pencil tool? What happens when you save an image into xcf2 (or whatever it will be)? Is there a point where parts of the graph are flattened, or will all manipulations that have ever been done to the image be replayed when the image is loaded again? (I have looked through the GEGL API docs and the GGGL pages so I think I understand the graph and operation stuff, it's the integration with GIMP I'm interested to hear more about.)

Re: [Gimp-developer] CVS HEAD dependency on glib-2.6 / gtk+-2.6

So I cleaned this up. I also checked everything else related to GTK and GIMP to make sure that I had no duplicates before moving on. Did you also check that there were no files named for example libgdk-x11-2.0.so* in /usr/local/lib or anywhere else on the system except for /opt/gnome/lib? (that file is a part of GTK+) I then un-installed (just to make sure) and built GLIB, Pango, ATK and GTK. There were no apparent problems during the build process. But now when I try to run GIMP I get the following error message: gimp: error while loading shared libraries: /opt/gnome/lib/libgtk-x11-2.0.so.0: undefined symbol:gdk_threads_lock I get the same error message when I try to run Firefox and GKrellM. This is the same error message I was getting after I installed the GTK 2.4 RPMs. I tested GIMP after building each library and it was fine until GTK was installed. I can get these running again by backing out GTK to the version that shipped with my distro. I did a search of the gtk-list, gtk-app-devel-list and gtk-devel-list and there was a thread on this error message on the gtk-list. But it was a dead end as there was no solution to the problem posted in the thread. Any ideas about what might be causing this? To me that sounds like it's picking up a 2.2 version of libgdk which didn't have that symbol. You could try running: ldd /path/to/gimp-2.0 to see which shared libraries it depends on. If it seems to pick up libgdk or libgtk from any other directory than /opt/gnome/lib (if that's where you installed GTK+), then you have a problem. You could also check the result of ldd /opt/gnome/lib/libgtk-x11-2.0.so.0 You can run objdump -T /opt/gnome/lib/libgdk-x11-2.0.so.0 | grep lock to make sure that the gdk_threads_lock symbol indeed exists in the libgdk you built. It should be listed in the output from grep. Hope this helps Robert ___ Gimp-developer mailing list Gimp-developer@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

(that file is a part of GTK+) Yes I did exactly that. I did the same for glib, pango and atk. But I did not try the same for gdk since this is not listed as a dependency for GTK. Actually, it is not a dependency. GDK is a part of GTK+ that more or less abstracts the low-level interaction with the windowing system (X11, Win32 etc). So, installing GTK+ installs several library files, for example libgdk_pixbuf, libgdk and libgtk. In the same way, GLib consists of libglib, libgmodule, libgobject and libgthread; Pango has libraries like libpango, libpangoft2, libpangox, libpangoxft, libpangowin32 etc etc. And in addition some other stuff like configuration files and header files gets installed as well. If you encounter any more problems you might want to take another look in /usr/local to see if there is more old stuff there. (But don't delete files randomly ;) ) The result is full of joy as GIMP and Firefox now run with out errors. Thanks for all the help. I will now be able to follow the development of GIMP and can hopefully help guide the implementation of color management. I'm glad to hear that!

CVS HEAD is a little too fast-moving, but I don't have a problem with using the latest devel version, and I don't remember anyone else having a problem with it, either. I'd hate to have to build my own GTK+ - it is absolutely non-straight-forward on Win32, rather forth-back-forth-back... I don't find it much more complicated than building GIMP once the build environment is set up properly (though that can be a bit complicated). What might be needed are better instructions for doing that.
