Multitouch possible in theory?

[Guest Spooke]

Ahh ok, thanks for clearing that up, Good luck and I hope you two get it all working!

You doing a great job for us! <_<

[Guest BigBearMDC]

Hey guys

I'm now updating my distro, hopefully this will fix my problems.

BTW I patched the driver once more, hopefully this will solve the offset problem!

I hope that solves your problem; seeing whats posted so far it looks like you're both close to a workable alpha build. I'm really looking forward to getting my hands on what you make. I'd be happy to do any mundane (or not so mundane) testing you want doing, if you would like me to. I'd love to help out with the code but I lack enough knowledge and experience, maybe I could learn by debugging.

Same here. I am a web developer, and I know a little C++, so I may be able to help you tweak <_<

Thank you all!

I already uploaded the driver, if you want to have a look at it :mellow:

Okay, distro is now karmic koala, gcc is 4.4.1, boot.img is screwed up -.-

I now uninstalled gcc-4.3, hopefully it works now.

Otherwise I'll have to install Ubuntu once again :(

Haha, guess what - reboot -.-

This is so annoying ... I'd really like to kick my pc out of the window...

I'll reinstall the whole environment.

Okay, I now made a backup of my data.

Ubuntu 9.10 is on my thumbdrive and I'm ready to setup my enviroment <_<

Damn it!

Now I remember why I hate Linux!

This is happening to me the 3rd time!

Ubuntu screwed up my external drive, now all my data is lost <_<

Anyway @xangma:

Could you please tell me what to do to get the enviroment working?

I always used Fedora or RHEL...

Really? I thought I read somewhere that Ubuntu is the most comfortable OS to compile Android with.

Ubuntu is the build environment recommended by Android.

What I'd say is that I believe it's Ubuntu 8.04 not 9.10 that is recommended (afaik), so maybe that would be a possible solution.

Wow, thats detailed, thanks <_<

But where did you get your toolchain from ?

I used the arm-eabi-4.4.0 toolchain form the android 1.6 source.

And which distro are you using?

Karmic?

I got mine from the 2.0 source I think. It doesn't change though I don't think.

Ubuntu 9.10, is that what you meant by distro?

[Guest BigBearMDC]

Yap.

Could you maybe upload your toolchain, please?

I'd otherwise have to re-download the 2.0 source on my own.

It's like 40 or 80mb or something, think you can download it separately with http somewhere.

EDIT: Will do it laters on though =] I think.

I can't find a toolchain thats working for me <_<

I downloaded one, but it doesn't even have all the necessary files.

[Guest BigBearMDC]

BTW my phone gets now recognized too <_<

Update:

Ok, I now downloaded the 2.0 source and I'll compile the kernel with its 4.4.0 toolchain.

Stay tuned!

Source the problem ... see if you can crack open a kernel that boots right down the the ramdisk folder and kernel, then bring it back up again and see if it boots. Then you know you're not making the boot.img wrong etc etc ...
