I know there is the WinCE development with Lazarus/FPC, but I was wondering if it was possible and if anyone had done any development on any of the Linux Based hand helds available?

Thanks

Like which ones? Nokia 770 tablet?

I got an N800 for Christmas and have wanted to try cross-compiling for it, but I haven't had the chance yet.

-SG

None in particular, just wondering if anyone has had success in compiling/deploying to that particular platform.

Hello,
can't say for your Nokia, but Lazarus works on the eeePC, with a Xandros distrib
Best regards,

The eeepc has an x86 compatible processor and it has an almost "normal" desktop linux distribution, so it's not that surprising that it works. OTOH the nokia tablets use an arm processor, the distribution is derived from debian but it uses eabi and its own specialized widgetset (derived from gtk) optimized for a small (albeit high resolution) screen: hildon, aka gnome mobile.
Fpc for arm generates oabi code, not eabi (Florian did something for eabi but I hadn't really time to test it on the tablet), command line programs with no special external libs should work just fine on the nokia, writing gui programs is not possible now.

I would recommend not to use -O2 on oabi (hard float). http://bugs.freepascal.org/view.php?id=10863

Thanks for the response, all.

We are in the process of re-writing our POS application and this time around we are wanting to included hand held table ordering. While it'll most likely be WinCE/PocketPC, I wanted to check out the possibilities of a Linux based hand held as a viable alternative.

Thanks again,

You are always welcome to create a new fpGUI backend for mobile devices. ;-) Felipe worked on a few WinCE changes for fpGUI-GDI (back in the v0.4 days) and apparently wasn't to hard to get the basics working.

BTW:
What does Linux Handheld devices use for the display backend. I guess X11 would be overkill. Maybe some framebuffer driver?

QTopia ones are using QT, others have their own framebuffer, fpGUI seems to have found a place where it's most needed :)

:-) A while back someone created a DOS backend for fpGUI using developer switchable framebuffer drivers. I think he had support for 3 different drivers. I've got the code somewhere, but I never really looked at it much because he made many other changes as well (eg 8.3 filenames only etc..)

At the time I had no need for a DOS backend, but maybe some ideas could be reused for a framebuffer for mobile devices.
