[dev] ARM port
[Please FU2 d...@education.openoffice.org ] Hello, Anybody working on ARM port ? Or interested to try ? As experimental test, I did the native OOo4Kids build on OMAP3, and work on new features (to be backported in OOo) could constitute a good study case for beginners in OOo source code.

To be honest, only a stripped down version like OOoLight or OOo4Kids is today - sort of- correct to my eyes. But even if it works, other issues jump, and my question was more about innovate and search new ideas.

Hi Ian Looks like I had to moderate your mail (probably not subscribed ?)

That's one role of the OpenOffice.org Education Project to innovate, and try new tracks. Unfortunaly, we didn't receive too much of support, including lot of promises, but nothing serious ...

Certainly a version of OOo that works well on ARM technologies is very important for the future. It could even be the case that if there isn't such a thing, the project will become largely irrelevant.

No, there's powerful multi-core ARMs. And there's armhf even mitigating the floating point thing.

Sorry, but I tend to disagree : can you please tell me the arm version choosen by default in OOo source code ? I'm just working at the optimization and what I see, tells me it's not optimized at all. But I can be wrong, and you'll tell me then ... It is obvious, that the current OpenOffice.org can run (I know) on current ARM, but will be slow as hell on the machine anybody can buy, today. Nobody will use that, and a lot of work is mandatory. Of course, you can acceed experimental boards, or not-public machines, what is different.

No, there's powerful multi-core ARMs. And there's armhf even mitigating the floating point thing. Yes, but where do you buy such machines *today* ? And so far, the only multi-core ARM I'm aware is the OMAP5 : scheduled somewhere in 2012 The reality, today says : you can buy development boards, including OMAP4 (like Pandaboard), and is not multi-core.

I was too fast : PandaBoard is multi core. I have some doubts OOo will use both, but worth a try. Anyway, this will not solve the performance issue at launching time Regards, Eric -- qɔᴉɹə Education Project: http://wiki.services.openoffice.org/wiki/Education_Project Projet OOo4Kids : http://wiki.ooo4kids.org/index.php/Main_Page L'association EducOOo : http://www.educoo.org Blog : http://eric.bachard.org/news

But I can be wrong, and you'll tell me then ... Even if you were right, how does it matter? OOo also is optimized only for pentiumpro on i386. And if you wished, you can optimize for whatever ARM you see fit. What I want to say, is : - provide OOo for arm version prior to v6 does not really make sense, because too slow, not enough or embedded ram and so on. - starting v6, or even v7, is a good compromise More precisely, starting armv6 version, the efficiency improved a lot. To provide some figures, doing the test myself, using armv7 flags, decreased the binary size from 3 to 5% (average value). Now that bad, when we know OOo size on the disk. It is obvious, that the current OpenOffice.org can run (I know) on current ARM, but will be slow as hell on the machine anybody can buy, today. Nobody will use that, and a lot of work is mandatory. Wrong. I tried it on my SheevaPlug, and it's quite usable. Is it me, or there is no monitor output ? The BeagleBoard is not that powerfull, but is hdmi capable. thanks a lot for the link though.
