Zaurus - pdaXrom / My Attempts To Build Qt4
« on: July 16, 2007, 05:00:05 pm »
Maybe, but glibc is very big library. On my PC it took more time to compile glibc then to compile qt... So it will be rather hard I think.

-- Does anybody know if there is any plan to introduce an newer compiler in pdaxrom? (I've seen a bug report about this)
-- Is it possible to build a newer glibc? mind that this point may need a rebuild of the repositories.
Compilation of gcc-4.1.2 took me around 10h (natively). But it won't solve all problems.

But more important, he pointed out that, even after succeeding he's found several errors that makes the library unusable (thanks man, you've saved me many hours of trial and error)
This errors becouse of glibc. In fact there was a small warnings like that:
Quote
qlocale.o(.text+0x116e4): In function `qdtoa(double, int, int, int*, int*, char**, char**)':
: warning: warning: feholdexcept is not implemented and will always fail
This is glibc warning (fixed in glibc 2.3.6), and that's why Qt have all those symbol errors, and etc (and that's why binary won't work). You can google it, if you don't belive. So main problem is very old glibc, not gcc.

Zaurus - pdaXrom / Qlwm Qt Window Manager

Where is this Gentoo for Zaurus? Is it easy to set up/boot? I may be interested...
Generic stage for pxa27x based pda's It have wrong kb layout, you need to unpack it to cf/sd card and manualy fix fstab and /etc/conf.d/net (to use usb-net) then you can emerge other parts of system.
Root password is gent00
http://gentoo-wiki.com/HARDWARE_PDA - here is howto.

Standart stage for pxa25x and other pda's that doesn't support iwmmxt.
Stages are rather fresh (iwmmt stage was built around 2 month ago, and xscale stage was built 10 day ago)

Here are a lot of interesting things there like portage-overlay with some pda-specific things (evtouch driver for pda's, patched xorg-kdrive with tslib support, precompiled binary packages, etc.)
Here are some additional links:

Zaurus - pdaXrom / Qlwm Qt Window Manager

Thanks for the hints!
No Problem. I was googling about Qt4 errors for a few days, after that I've realized that it is faster to kill pdaXrom and use Gentoo. Now it is compiling (30h already) without any warning...

Quote
After trying the cross compiling for a while I simply gave up, Qt is trying to build some tools to use them afterwards in its own build process... so I had to go native (at zaurus speeds)
Yeah, Qt is very big library. It should took around 50h to compile it natively.

Quote
I knew the bit about the compiler, I had to disable the precompiled headers for having something going (it complained about some pch error after 3 hours of native compiling).
In fact there is one thing that you haven't found - it says something like:
Warning: bla-bla-bla will always fail!
this is the most dangeourus thing - it is becouse of glibc (was fixed in 2.3.2 only), and that's why Qt4, even if you manage to build it won't work (in fact it shouldn't build at all - after ~8h you'll get a lot of asm-related errors becouse of that little warning).

Quote
And yes, maybe the problems I am having are related to glibc (actually this brings light to the spot!) Does anyone know if there is an updated glibc version for pdaXrom?
There was 2.3.2 for pdaXrom 1.1.0 Beta1 somewhere. But be careful - glibc 2.2.x and 2.3.x can be binary incompatible

P.S. You probably will need http://svn.debian.org/wsvn/pkg-kde/branche...file&rev=0&sc=0 and http://svn.debian.org/wsvn/pkg-kde/branche...file&rev=0&sc=0

On my side, I am still unable to compile Qt4, I'll keep trying
As I remeber Qt4 needs at least glibc 2.3.2 (pdaXrom have 2.2.5 by default). Then it is recommended (but not necessary) to use gcc 4.x (can be easiliy compiled). Configure of qt4 by default can't understand that armv5te is arm and uses arch=generic. It may result in compiller error when it tries to compile x86 asm on arm... In theory Qt4 can be build (Angstrom have packages with Qt 4.3.0), but on pdaX it is very painful becouse of outdated libs.
P.S. Since Qt4.3.0-rc1 qt have experimental support of iwmmxt instructions, but as google says it fails to build with that options. You can try configure -iwmmxt

Zaurus - pdaXrom / Dual Booting Pdaxrom And Angstrom?
« on: July 13, 2007, 06:06:35 am »
Quote
well... It would probably be useful to merge angstrom patches to the pdaxrom kernel. EABI seems like a good idea. Further it would seem like a good idea to have a unified kernel. pas that, maybe a re-compile-fest to bring older apps with compatiblity problems up to speed?
https://www.oesf.org/forums/index.php?showtopic=23865&st=75

There was a request to bring glibc 2.4/2.5, gcc 4.1.x and eabi support to pdaXrom (see bugtracker at pdaxrom.org ).
pdaXrom now have very old glibc and gcc (gcc 3.4.x doesn't support EABI properly, and glibc 2.5 have a lot of fixes for eabi support)

not been able to figure out how to make a Angstrom kernel by starting from a vanilla one.

Zaurus - pdaXrom / Help New Kernel For Pdaxrom
« on: July 12, 2007, 07:46:00 am »
I've tried to apply CFS patches (Compleatly Fair Scheduler - new CPU shceduler, that will be included in kernel 2.6.23)... It acts very-very strange... Some times it says "Oops" on startup, but if it doesn't a boot to login prompt took a lot of time - for me it was around 12h(!) to boot...

I'm now tring to combine old OZ's patches and handhelds kernel (to make unified ebuild for gentoo for both pda's I have). I thik I'll try to build it soon and post results here.

Where can I get your modified patches?

I don't know where to find libiconv for x86 Ubuntu
Maybe it is called just iconv?

P.S. But I've always thought that iconv-compatible libs are now provided by glibc...

You need either eclass.patch ( ftp://gentoo.ru/pub/eclass.arm.patch ) or native compiled bash.

I thought altboot used kexec?
Yes, it use kexec, but it also starts rather fast... So maybe it can be useful for dual booting?

Although I do not like it much currently the solution that would take the least effort for multi boot is kexec with a rare exception of r121+ pdaxrom versions that can share the same kernel (as a matter of fact on my C860 I have r198 in nand and a higly modified r121 in MMC and use just u-boot to select whic one to boot).
And what about OZ's altboot? I thought it could boot system from other than nand devices...

Would it be possible to do the same and boot from the microdrive instead ? (I'm looking for a solution to run r198 from microdrive) ?
In theory. I was trying to get Gentoo boot from microdrive, but for some reasons kernel detects partitions after booting (see at emergenc system - I got there "Unknown partiton layout" - same thing I get if when booting from microdrive)
