Creating own native qte apps

[leprechaun]

Trying to set up a building environment in linux for creating own native
qt embedded apps for the phone. So far I've only gathered information on how to cross-compile, fetched header-files for the non ezx-libs in the phone and found a suitable toolchain for cross-compiling.
Such an environment is quite massive though, the toolchain alone is 70Mb, a complete version will be far to big to send to this forum..

Well, anyway.. has anyone else been thinkering with this kind of stuff already?
Would anyone here be interested in it? What I'm aiming for is to get (at least part of) stuff like this: OPIE to run on the e680, it would also open up for more/faster emulators..

i have tried i already with a precompiled toolchain from www.snapgear.org for arm.
Then i downloaded from trolltech qt-embeded, because this is what is on the E680.
I compiled one of the example apps from qt-embeded for the phone and started it there but i got an error messages (cant remember exactly). i figured out that the precompiled toolchain was for arm without soft-float support.

Then tried to create to build an own toolchain from source but for now without success.

can you send me the link to the toolchain you found?

Check out: http://arm.nihilisme.ca/
It has both compiler and some nice papers of the arm-arch.

I downloaded the xscale one with 2.4 headers, from what i know the e680 has
kernel 2.4.20, gcc 3.3 and glibc 2.3.2, which should fit nicely with the above compiler
since the only diff would be the kernel version 2.4.19 and that shouldn't matter.
Also i've chose qte 2.3.6 since that also is the version on the phone, my thoughts are to
copy the libs from the phone and use only the headers from the source-package..

What do you think of that?

Keep on working that and plz send me the full software when it is out

Alright!! I ran a first test a few minutes ago, just test a simple hello program
no qte just stdio.. It actually works!
No much, but a start at least.. confirms that compiler is ok, and libc too I guess. I will try to compile a qte-hello program later today..

(omg this really excites me, hope it works!!)

nice work dude..... keep it up.....

p/s :: dont forget to share the app with us if its succesful...

Ax, it seems that open source qtopia headers doesnot work with these ezxlib from the phone. I have compiled and recieve lots of link errors. But with the opensourcelibqpe and libqte it worked (we must copied these lib to the phone and set LD_LIBRARY_PATH). I tried also the embeddedkonsole compiled for sharp zaurus, but it told me that '/dev/ts' not found. I recomplied libqte (replacing /dev/ts in source of the lib with /dev/touchscreen) with linux-arm-g++ in cygwin but it not worked (error: cannot load libqte). damnit. Btw, who knows if there is an arm version of gtk+ ? I tried to port an app but it uses gtk+

hm, i downloaded crosstool from http://kegel.com/crosstool/
and build a toolchain with softfloat support for arm.
(the xscale in the phone does not have a floatingpoint unit)

Then i compiled qt embeded with all the example apps. But running the example hello programm failed with "SIGILL (Illegal Instruction)".
Tried to find the problem with strace. Compiled strace with the mentioned toolchain and executed strace with the hello app. but i can't determine the problem ;(

does someone have success on compiling apps for the phone?

Console-apps are running fine. I tried strace, a smal hello world and the fb2png. But all other apps failed ;(
