Foundation

After some efforts, I had everything compiled -- ffcall, foundation, appkit, etc. for the nokia. But then my test program crashed :-)

Removing extra libs (hm.. ffcall.. :-/ ) I have something working though: Foundation !

[ note that I got the NXConstantString error, so it looks like library loading order matters (lobjc / lgnustep-base)... changing the ordering in the makefiles make it works though ]

Now.. I compiled gnustep-gui and gnustep-back, both with xlib and art. But the xlib backend crash (it can't find any available font on the nokia apparently..), and the art backend (after some efforts -- #ifdef XSHM to get rid of any XShm calls...) "nearly" works: with my test application (a simple info panel) it displays a window, but without any content (plain white), and complains about bad window... Yet it seems to receive events (I can click on the invisible buttons ;-) so it looks like some art display problem, perhaps just because the nokia uses a non conventional color ordering / depth.

Well I need to come back on ffcall and check if it's the culprit or not for the crashing thing -- having ffcall won't be bad for the gui :-) and try to understand what's wrong with backart... but all in all things progress ;-)

ah, I also did a very stupid mistake the other day, compiling gcc for arm-softfloat. Naively I thought you needed a soft fp implementation, as the arm doesn't have a hardware fp. But what I didn't know is that there's two kind of soft fp -- kernel and softfloat. Worse, you can't link binaries compiled with different fp emulation. And of course, the nokia is compiled with kernel fp emulation, not arm-softfloat.. So I was good for recompiling gcc ...

Though, one good thing is that with arm-softfloat ffcall didn't compile at all (seems that the asm bits of ffcall uses the fp registers for the arm platform), while now it compiles (but as I said it seemed to be the cause of the program's crash, so it's perhaps not as encouraging as it seems ^_^ -- although I need to double-check and recompile things nicely). Considering libffi closures don't work on the arm, if ffcall works that's a good thing :)

Anyway as soon as I have something working decently I'll post a full guide to cross-compile GNUstep on the nokia (and probably some binary packages too if you just want to install it on the nokia).

Nokia 770

I received today my new shiny toy, the Nokia 770:



I put online some pictures of it..

First impressions:

• it's light ! yet it doesn't feel "crap" :-)


• the form factor is surprisingly nice (even if coming from a newton I wouldn't mind a (physically) bigger screen)


• applications are a bit slow to start. Hopefully things will improve -- even if as it is it's ok, I wouldn't mind instantaneous starts ;-)


• redrawing is a bit slow too :-/ is it because of X or gnome.. ?


• the screen is absolutely gorgeous !! really beautiful and luminous :-) (the pictures I took don't completely do it justice)


• playing movie is ok (there's a trailer for ice age 2 on the machine), but could be improved..


• lack of pppoe configuration for wifi VPN (or if there is, it's not obvious, but well, I just got it, so I perhaps overlooked something)


• installing a package is easy :-)


• The UI is quite good, as a PDA UI -- definitely better than PocketPC (well, duh..), obviously less good than the newton, but hey, it's not too bad..

So well, overall, I'm quite pleased -- the device is indeed very, very cool. Things can be improved, but it's already quite nice. The UI is ok, even if what I would like to do is (obviously ?) install GNUstep on it, and then modify GNUstep to blend on the Maemo platform (with a possible replacing of maemo in an improbable future). Anyway, as it is running linux, it seems an ideal platform for me -- both for experimenting with etoile/gnustep on a PDA (see a previous post about that, and see what I posted about the newton for what I think is good on a PDA...) and as a good client for the system I'm working on at uni...

I'm not sure if there's a market for a "web tablet" device, but I don't think that the Nokia 770 will only be a "web tablet" anyway :-) -- there's already ports of doom, abiword, the GPE pim stuff, etc.

Nokia has a winner in the linux community I think :-) -- which means that you can expect lots of software for the Nokia, and it already started... It also look like an excellent device for ebooks, administrators (as an X/VNC/ssh terminal), etc.
