Re: Hippocanvas error :(
Tomeu, Talking with Joel, looks like hippo-canvas only builds the python bindings if the prerequisites are already installed. If not, silently omits them. I added python-cairo-dev to the ubuntu dependencies, but perhaps the python bindings should be built incondicionaly? what I did was $ sudo apt-get duild-dep python-hippocanvas but still the error remains, Marco is right, hippo.so has conflict with libhippocanvas-0-1.so that is present in the install/lib/ directory, removing these libs makes hippo.so work but poses new errors that are journal fails to load and every other activity as well logmanager.py get permission denied errors to write to .sugar/default/logs directory :-/ and some error that says Unable to create window at hexa vaule some thing and again building libhippocanvas will remove these errors but import hippo will fail :( any body tried sugar-jhbuild in Ubuntu Hardy ???

Naturally, this is somewhat the opposite of what we want to happen when running in fullscreen on screens of various resolutions, in which the subcomponents within the UI should independently scale or not, as appropriate. There's a fair amount of work to be done there as well, to make sizes and proportions appear correctly no matter the resolution.

See http://dev.laptop.org/git?p=projects/jukebox-activity;a=summary for an example of a media player activity based on gstreamer. I guess you could bundle an mp3 decoder for gstreamer inside your activity. Good luck, Tomeu -- Waqas Toor ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [Server-devel] Mesh Portal Question
Hello All, first let me define the scenario of my test, The distance between XO1 and my active antenna is 350 meters and the distance between XO2 and XO1 is almost 700 meters XO1 and XO2 can talk with each other very fine by simple mesh portal, i.e. i used chat activity between them XO1 gets connected with the school server without any hassle ( automatic ). Now what i am trying to get is to ping School server from XO2. I havent yet done any configuration or assigned any IPs, what i am testing is that of autoconfigurations XS -- XO1- XO2 now how to access XS from XO2 using Hop of XO1 Regards On Feb 12, 2008 11:40 PM, John Watlington [EMAIL PROTECTED] wrote: Giannis, Waqas indicated that he is not blinding his laptops. wad On Feb 12, 2008, at 11:08 AM, Giannis Galanis wrote: I believe in the blind table of XO-1, you have to include the anycast address C027C027C027.

Re: Activity bundle Query
Hello , but i was able to run the application from the terminal using gij command and it works fine ... so is there a way that i could bundle it what does these lines mean The exec key specifies the executable which Sugar runs to start the activity instances. Environment variables given on the exec line are expanded. Executable files should be placed into the bin/ directory in the bundle. It should support the following arguments: -b, --bundle-id Identifier of the activity bundle -a, --activity-id Identifier of the activity instance. -o, --object-id Identifier of the associated datastore object. -u, --uri URI to load. are they helpfull ?
