Re: Asking for information about programming in JAVA at Nokia device
Hello Magda, we have recently started a project with the aim to maintain a full featured free java stack for mobile linux devices, called JaLiMo. The goal is to package and tailor existing jvm-related projects, as well as develop APIs for easy integration with the target platforms. Since we have recently started, our mailing list and Web-Site will be available in a few weeks. Currently we have managed to get the recent cacaojvm (see www.cacaojvm.org), gnu classpath 0.93 (see www.classpath.org) and java-gnome 4.0.2 running on the n770. http://www.mancke-software.de/jalimo/screenshot_java-gnome.png Since our state is experimental at the moment, we have no official packages now, but you can grab some simple tar.gz archives from http://www.mancke-software.de/jalimo/. (unpack to /usr/local/ and get in touch, if you have problems with them.) They are only tested with n770, I don't know, if they are running with your n800. There is also a classpath 0.91, together with a jamvm available out there. (http://www.internettablettalk.com/forums/showthread.php?t=2896) This 0.91 has a working Swing/AWT which will be hard to get running for later classpath versions, because it needs a newer gtk. Both, the jamvm and the cacao seem to work fine. The cacaojvm (JIT) is approx. 2-3 times faster than the jamvm, but has a huge start up time (~3 sec, instead of 0.7 sec). What is the project, you are focussing on? Regards, Sebastian magda chelly schrieb: > Hello, > > I'm a student beginnig to program with a Nokia N800, > and I'm in search for some information.

Changes to Sardine meta packages
Hi, I made some changes to the meta package setup used with Sardine. There is now a new meta package hildon-application-framework-dev that is intended for use in Scratchbox when you develop for Hildon. It's primary purpose is to conflict with packages that are deprecated. You should _not_ use it in your Build-Dependencies as a shortcut. Please continue to use fine-grained dependendencies on the packages that you are actually depending on. The general idea is that the hildon-application-framework package gives you the complete functionality, and you would install it on your device; the hildon-application-framework-dev package makes sure that you have a suitable devlopment environment and you should install it in Scratchbox. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

1. N800 as a webcam device: I already recommended this idea on this list earlier for anyone looking for some n800 related project to work on.

I'm not sure N800 gadget drivers sources are available on maemo repository, and if it isn't only Nokia internal guys could do that (may be someone is writing such gadget) BUT yes it could be done in user space if you want: 1- define a network/stream protocol suitable for video like devices and write a default user space app getting data from v4l2 and sending over networking that implemets that protocol 2- write a v4l2 driver for it on desktop side this way it would work for every linux (having v4l2 device) and desktop devices regarding radio may be it could be done with Usb Audio Class (I have to look at this class) in the same way.

It would also be useful outside maemo, aka at debian and at ubuntu. So it would be nice if it can be implement at the lower levels, ie apt/dpkg. One way of implementing this is: 1) When installing package store the origin (available from the Relese file of repository) of the package into package /var/lib/dpkg/status. 2) When upgrading, refuse upgrading that package from other origins. Provide a --force-override origin for power users.

Re: Maemo at Google's Summer of Code 2007?
Hey! Do you have an idea who could try to apply in the name of Maemo? Anybody from the maemo team who is interested in this happening? Well! i would be more than happy to mentor any of the following projects if someone student wan to work on them as his Google SoC project: 1. N800 as a webcam device: I already recommended this idea on this list earlier for anyone looking for some n800 related project to work on. This would ideally involve a user-space streaming application on the device and a v4l2 device driver on the PC. Now that everyone knows there is FM radio capability on the device, the v4l2 driver could also provide that capability on the PC. 2. GOD (Gstreamer On-Demand): Remote Gstreamer pipeline/element creation and manipulation. This project would also provider wrapper lib to create distributed gstreamer pipelines. For details on this idea, please refer to my blog starting from 15 Oct 2006 (http://www.advogato.org/person/zeenix/diary.html?start=96). Although this project is not directly related to maemo/n800 but i am quite sure, n800 can be the biggest beneficiary of this project. So if anyone interested, please apply to SoC and let me know. :) -- Regards, Zeeshan Ali Design Engineer, SW Open Source Software Operations Nokia Multimedia ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: Application Manager scripting, second try
Hi Mariuses and all, I must say that I like this second try better :D One thing that I wondered is that could the "Adding catalogues interaction flow" be handled with the same [install] group syntax as the second "Installing a package from the network catalogues" flow. With the difference that the [install] group would only have a `catalogues' key and no `package' key. But at a second thought it might be a bit confusing if the catalogues are treated differently in these two cases...

Yet another possibility would be to name the catalogue groups like this: [catalogue foobar] name = ... Perhaps it would be more descriptive but I don't have a really strong preference here.

maemo-fm, feedback
Hello, I have tried to get feedback on this issue using the [EMAIL PROTECTED] list and the mozilla bugtracker but still have no luck. lets try it this way. It is very frustrating to get no feedback. We kender is I have started porting an application (shell-fm) that allows to listen to last-fm streams from the command shell. we have been searching for similar projects and I found the maemo-fm project, which seemed to be trying to reach the same goal. kender tried to contact the developer though personal mail and the "Join us button" on the project page, but he did not get an answer.We have asked on the #maemo channel, so, if someone knows the developer, but nobody seems to know him.The maemo-fm[1] project was registered 2006-09-30 but did not ever release any files or posted code. We like the name of the package and would like to take over the project. What do I need to to to accomplish this? on irc Jaffa suggested a cleaning project. Authors of non-active project would receive a mail requesting them to publish code or give the project away This would happen by sending a notice to all the "head developers of any project", if they don't answer the mail and the project is deleted or transfered. This is called a garage sale :) The mud project is having the same kind of problems with the exist ports that are listed in on the wiki, we are ready to port more applications. see http://www.maemopeople.org/index.php/jaffa/2007/01/31/mud_ports_of_existing_packages Your advice on this matter would also be appreciated. greetings [1] https://garage.maemo.org/projects/maemo-fm/ p.s. this was the bugzilla report https://maemo.org/bugzilla/show_bug.cgi?id=1071 ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

pun intended? ;-) C pointers and string operations are the first place
to start looking for segmentation faults.

Hint "std::string::compare ()"
Hint "std::operator< "
I'd start here. It has been a long time since I looked at gdb output of
someone else's code. The thing that I see as a hint is string::compare
from the std library. I am thinking <> operations, etc but
this looks to be c++ code. So go back and check how you handle your
string compare operations. What are the inputs to the string
comparisons, etc. Are your string lengths long enough? Do you have
null terminated strings. Have you properly initialized the variables
that are being used. These are things that I would look for in a
segmentation fault. These ideas may help with a porting issue too.
I inherited a bunch of Oracle Pro*C code once upon a time. I had to
clean and clean and clean that program. Much of it had to do with
making sure that the string lengths were of the right length. The other
issue was improperly initialized variables. That crap still runs in the
middle of the night. However, I have been successfully sleeping through
the night for many years now. Moreover, If gdb is taxing your mind,
there's nothing that says you can put some printf statements to locate
where the program segfaults.
I hope this helps.

Greg
