object.cpp build failure on Solaris
by Christopher Wiedel 02 Jul '05

I've been trying to build Inkscape 0.41 on sparc-sun-solaris2.8, and have run into a bit of a problem. It configures fine, and when I start 'make' it initially goes well, occasionally popping out warnings like: node-context.cpp: In function `void nodepath_event_attr_changed(SPRepr*, const gchar*, const gchar*, const gchar*, bool, void*)': node-context.cpp:313: warning: cast from `GTypeInstance*' to `SPItem*' increases required alignment of target type node-context.cpp:322: warning: cast from `GTypeInstance*' to `SPItem*' increases required alignment of target type However, it blows up when it hits src/object-edit.cpp. Or more accurately, something inside it. It throws out a great many of the same type of warnings as the ones above. This doesn't appear to be the problem, since other files had the same warnings, but were able to compile. It winds up with this: object-edit.cpp: In function `void sp_offset_offset_set(SPItem*, const NR::Point&, const NR::Point&, unsigned int)': object-edit.cpp:897: warning: cast from `GTypeInstance*' to `SPOffset*' increases required alignment of target type object-edit.cpp: In function `NR::Point sp_offset_offset_get(SPItem*)': object-edit.cpp:909: warning: cast from `GTypeInstance*' to `SPOffset*' increases required alignment of target type make[2]: *** [object-edit.o] Error 1 make[2]: Leaving directory `/usr/foo/inkscape/0.41/inkscape-0.41/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/foo/inkscape/0.41/inkscape-0.41' make: *** [all] Error 2 This is using gcc 3.3.2. It doesn't appear to have any actual error message that I can find. I would appreciate any pointers. Thanks. -- Christopher Wiedel

Actually, it seems like that's exactly what's going on, judging from the way Inkboard processes messages: the new object message arrives, so Inkboard creates a new object. However, only _then_ does it actually parse the type attribute and set it. I'm reworking received_new_object_helper to extract and set the type attribute before it creates the new object. Hopefully, this'll fix the problem. -- David

Inkboard CVS updates
by David Yip 01 Jul '05

01 Jul '05

I have committed a number of fixes to the Inkboard CVS <http://sourceforge.net/projects/inkboard> that address crashes related to buffer overflows. Instructions for building and running Inkboard can be found in my request for Inkboard testers that was posted to this list. Inkboard should now be much more stable than it previously was, sans conditions like invalid Jabber usernames or passwords. (I haven't gotten around to debugging those yet; I've been chasing down another bug, which is described below.) In a session between two peers Alice and Bob, if Alice sends a star, spiral, or ellipse, it will show up correctly on Bob's canvas, and (almost) any manipulations that Alice makes will be correctly replicated on Bob's canvas. However, if Bob manipulates the star, spiral, or ellipse in any way, the changes will not be correctly replicated on Alice's canvas. Additionally, Bob will not see the object as a star, spiral, or ellipse -- he will only see it as a path. I think these two problems are related, and since I'm not sure where to start with addressing the first problem, I've been focusing on the second, in the hope that it will cure the first :) I don't think this is a case of missing information: if Bob saves the document, exits, and then reopens it, any star, spiral, or ellipse will be correctly recognized as such, and not just a path. I think there's just something that Inkboard is just not triggering correctly. If anyone has any ideas on where to look or what to look for, I'd greatly appreciate them. Another, smaller bug: gradient editing is not replicated properly. Pressing "add" will replicate the changes, but the gradient objects themselves fall out of sync. Finally, just some thoughts about the near-future integration with Inkscape: Ideally, I'd like to begin merging Inkscape with Inkboard only when all of the bugs have been ironed out of the Inkboard code. That's rather unrealistic, though, especially since the act of merging may expose new bugs anyway! :) So it may be a good idea to create a new branch in the Inkscape codebase specifically for integration with Inkboard, and then merge branches when an acceptable level of robustness is achieved. -- David

current cvs - problems compiling win32

Hello, I checked out a fresh copy from the cvs. This does not compile with mingw because a used define is commented out in the makefile. See below. I also compiled a win32 installer for the 0.42pre0.

terminology proposal
by Jakub Steiner 01 Jul '05

01 Jul '05

Hi folks, Until yesterday I haven't had a chance to play with what you call effects. Because I believe this is a misleading terminology I want to propose an alternative: Scripts ------- Scripts are little programs, written in interpreted language, that supply extended Inkscape functionality. They can work on objects, or even drav new objects on the canvas. Both Blender and GIMP projects eventually came to a conclusion that it makes no sense to separate scripts form the core functionality in terms of interface. A script should be free to register anywhere in the menus, based on its functionality. Grouping them, creating yet another menu structure, just because they are written in a particular language is not helpful to the user. Yes, it is pretty much what you call effects now. Filters ------- Filters are operations on selected objects, on their bitmap renderings even. The result of the filter replaces the original object and cannot be easily changed in future. The resulting image is stored in the file upon save. Effects ------- Effects are similar to filters, yet they are "dynamically" applied on a bitmap copy of the object at the target resolution. Only effect settings are stored in the file on save, and the effect needs to be recalculated (possibly some caching/preview voodoo needs to be applied to speed up preview). cheers -- Jakub Steiner <jimmac@...659...> Novell, Inc.

Incidentally, do you know what would be required to increase the default snap distance? It's currently quite small. -mental
