Recently I have been working on ZBedic because I wanted to update it and port it to Qt 5 so I can use it on my desktop. Long story short, porting it was too much hassle so I started a clean implementation. That project is called Frasmodic.
Good luck with your new project. If you need any tester for the Linux version, feel free to ask me.
I think it won't be possible to build a Qt 5 version on Zaurus so the best thing to do is to try to update ZBedic. For example, libbedic is statically linked. I can make some improvements to it then build a dynamically linked ZBedic. However, the question is who would use it ? I don't see so many people posting on here saying they are using Sharp ROM and the majority of users seem to use zalarm without GUI (is that correct ?)
Maybe it could be worth a shot to try to run QT5 on Alarmz under a lightweight window manager like Ratpoison. The latest version of the latter has been recently successfully ported to pdaXrom and it is said to be running well. Don't know how fast would QT5 apps run on it though.
I'm at the moment using Alarmz, but once I'll have a stable setup I'm planning to install again Cacko and check its support for Japanese writing, for ZBedic and (if it will be possible to port it) Anki, plus for checking out older apps.
I believe most people here use Alarmz under a shell or pdaXrom; I know of only one user using the stock Sharp's ROM, as he has a 5500.
I also noticed from web history that someone generated a Japanese-English dictionary from EDICT where they mixed kana and kanji keywords together in the index. I have been generating similar dictionary files myself but I separated the kana and kanji versions. Having a combined index seems very sensible, I think I can adapt my scripts so that is also in my plans.
It would be much more handy to have both kana and kanji displayed for each word result, although for now I only check for kana keywords.
Finally, I am playing with the idea of porting Kanji Nirvana to desktop. I have been poking around the source; it seems doable but I have no idea about a time frame for it.
Never seen it before, I'll definitively try it under Cacko:
http://freecode.com/projects/kaniI have noticed that Freecode is now read-only. I'm worried that it might be taken off-line someday and thus the sources would be lost, we might contact the author and ask him to move the project to e.g. Sourceforge. Also, I have found another project called Nihongo Nirvana which is more recent, is that a fork of Kanji Nirvana or just an updated version of it?
