Hi
My goal is to build Ubuntu Touch for the Ideos X5 U8800. So far, I have only had trouble finding and setting up the source for a cm-10.1 build. Finally, I gave up and built cm-11 using Blefish's device source tree. Everything works just fine.
So the question is: Can Ubuntu Touch be built using cm-11, or is cm-10.1 the only option at the moment?
Best regards,
aribk
They switched to Android 4.4 some time ago. Don't know why they haven't updated the wiki yet.

Ubuntu is based on CM? Thougt the only thing in common is parts of the kernel??
So, it will more or less be able to port ubuntu to other devices just by changing kernel and baseband?

Libhybris is being utilized by Ubuntu for Devices, Sailfish, Open webOS and others to form a base layer compatibility with Android hardware drivers (above and beyond just the baseband [radio]). This is what gets the ports to work with Android hardware... http://en.wikipedia.org/wiki/Hybris_(software)
The mainline efforts have focused on Nexus hardware and seem to have formed a consensus that CyanogenMod 10.x is the best jumping off point.

hi guys, did HTC ever release the source code for the 2.1 update?
No. htc are bell-ends and don't even release driver source code, let alone code for their "superior" gui. Hence why it takes a while to port newer versions of android to the hero. Developers have to implement loads of dirty hacks and backports using kernel binary blobs they manage to extract from the 2.1 upgrade.

well thats just bad news!!
but they did afaik release source code for the kernel for many of their phones didn't they, what i would like to know is what does this mean to developers, what can they do with the kernel source?
The kernel is just a modified linux kernel, which has been open source since the early 90's.
Developers can do quite a bit with the kernel, is is basically the bridge between hardware and software.
However, despite running Debian since Etch was the latest stable release, my knowledge of the linux kernel is limited, so you would have to ask a developer for specifics.

thanks for your help
info on webkit source please..
i was at HTC's Developer Center and i noticed that HTC released the "webkit source code" for several "Sense UI" models, including the HTC Droid Eris, which very much shares our beloved Hero's specs...
i was wondering is this webkit compatible with our GSM Hero, and why didn't HTC release the webkit source for the GSM version?
the reason i'm asking is because i want to take out libwebcore.so alone and patch it, and replace the one in Hero...
After seeing that the Galaxy Nexus is so far running kernel 3.0.1, I was wondering if it is possible to update current kernels on existing devices to a 3.x kernel. I have a little experience in at least successfully upgrading Debian to 3.1 kernel, but compiling for android is a bit different it seems.
On my G2x, which is running 2.6.32.45, I attempted to compile a 3.1 kernel, and it refused to boot into CM7. I followed the CM kernel compilation guide, but to no avail. Would this most likely be due just to error on my part during compilation or configuration, or do I need to wait for LG to make their own 3.x kernel based ROM to derive the proper drivers?
Is it even possible at all to "upgrade" to a higher kernel version if the phone manufacturer has not done so themselves already? Thanks for any input!
Yes, you will have to wait until LG releases their version. No, its not possible to upgrade to a higher kernel version if the phone manufacturer has not done so themselves (you could try to compile one based on a higher version but that would have to be from some other manufacturer and most likely it will not work). To answer your title question, yes, it most likely will be done in higher versions of android.

Thank you for replying so quickly and concisely!
That is a bit disappointing, but realistic I suppose. In the 3.1 kernel changelog there were a ton of Tegra based changes/fixes, so I figured I'd try it out on the Tegra based G2X. What is it that the newer kernels are missing that severely hinders upgrades on android as oppose to desktop (x86?) platforms?
In more realistic terms, the most likely way of being able to jump up to a higher kernel would be say, using the 3.0.1 kernel from the Galaxy Nexus dump as the source and use a current 2.6.32 config with it? I might try it out if it's a little more likely!

The newer kernels aren't missing anything. In fact, they have many more features, optimizations, and fixes which do not allow them to work on earlier versions of android.
More likely yes, but still, it most likely will not work (since these earlier version of android won't support all what higher kernels and android versions support).

Just ported this 3.1 kernel last night. I took the Linaro 3.1 Linux kernel, and integrated ashmem, pmem, binder, and lowmemorykiller.

It's for an OMAP3 platform. If you are looking to port a Tegra 2 BSP to a 3.1 kernel i'd be willing to help get it going.

That would be great! I've never considered Linaro before. From reading up on it, it seems to be an optimized kernel for ARM (and other mobile CPUs)? You might have to make a tutorial on how to customize your own kernel

I'm about to deliver some Android changes to this tree. If you are serious about supporting Tegra2 please point me to your current kernel's source code. I'll begin porting the BSP and drivers.

This looks great! Would you be including the Tegra 2 BSP and drivers into the embedded kernel? I (and any other Tegra device owners) really appreciate the help!
Here's the source for the device I have; LG G2X (P999) with a Tegra 250 (sorry about mediafire, LG doesn't allow hotlinking):
http :// www.mediafire.com/?9zt7suw7nivbr7o
If we wanted this to work on a Cyanogenmod based kernel, I guess you'd have to look at the Cyanogen Git. Here's the the P999 cyanogen git:
https :// github.com/CyanogenMod/android_device_lge_p999
You can look at getting set up with it easily here, I believe:
http :// wiki.cyanogenmod.com/wiki/Building_Kernel_from_source
Thank you for helping! If there's anything else I can help with, or resources you could post that would allow me to help you better that'd be great.
I am pulling down the sources now. It's been a busy week getting ICS up and running but now I have some time to play. I'll keep you posted on my progress.
How it's goin'?

Is everything OK?
I have a LG P350 which development has stopped but i want to keep it updated, i have my computer ready for building, also i have kernel sources, Cyanogenmod 11 and 10.1 sources too, (I don't know exactly if 10.1 sources could help) and i know that i need to apply patches to work on Armv6 but i don't know how to apply them to the source code, also i don't know if i would just need the pure source code to build or i need to do more modifications to it and finally, i don't know if the rom would work with 2.36 kernel which it's the most stable one for this device, i'm very new in this but i know that i can keep update my little phone, thank you all in advance for help.

Hello, looking at your situation here is what I can conclude. First off you will need to change things for building on ARMv6 architecture, check this out for example. But your biggest problem will be that Android 4.0+ uses Linux kernel version 3.0+, and with the 2.36 kernel you have a lot of things will be broken and need fixing. That being said if your up for the challenge for it cause that's what were all about .

Well, i got this http://forum.xda-developers.com/showthread.php?t=2144790 that is the most similar phone talking about hardware, it has 3.0 kernel working well so i thought i could port it, i found this http://stackoverflow.com/questions/15961306/porting-kernel-from-another-device so i think i would have less problems due hardware similarities (Look here http://www.gsmarena.com/compare.php3?idPhone1=3516&idPhone2=3735 ) so, if i have cm11 pure sources, i add this kernel sources and some patches i would have it booting? Sorry for this very dumb question but, i didn't get at all about the armv6 part, how to apply patches, which i would need and all that, i really want to learn about this so thank you for this answer and the next ones :good:

The best way to start is use the ARMv6 branch of Cyanogenmod 11, replace the CM 10.1 in the previous linked build guide with cm-11.0 ("repo init -u git://github.com/androidarmv6/android.git -b cm-11.0"), and then to direct the build to use your kernel take a look at this guide on integrated kernel building with Cyanogenmod.
Just starting to learn how to build ROMs from source using Ubuntu in VirtualBox, so bear with me, but is there a best version of Ubuntu to build ROMs? I've seen 14.04, 14.10, and 15.04 all thrown into the mix. Are they all more or less the same? Or is there a certain version better compatible with this type of stuff? Appreciate any help.

More or less, they wont make a difference depending on what you're building. Generally, AOSP and CM will build fine on any, but if you plan to use custom toolchains, the 15.04 is your best option because of updated libraries.
I'm using Ubuntu 14.04 STL. I think the UI and functions are useful enough.
Decided to go with 14.04 and everything worked out great. Thanks for your help guys!
Was Wondering as We got All Sources and a Good Development
Why not Somebody Port Ubuntu Touch or Firefox OS
as Both the Operating Systems Sources are Available
I Myself might have done it But I'm Out of FUP ;_;

Ubuntu touch its an good idea
This is a great idea and I'd love to see Ubuntu touch and get my hands on it
I tried sailfish os to port but it fails because the cm12.1 sorce code is not fully available and this makes it difficult for ubuntu you need cm10 or 11 resources , therefore it is almost impossible
but not perhaps maybe even
Maybe it east for me too much paperwork
Actually, Ubuntu touch is great idea though. But it's complex cuz it's need older android source code like jelly bean and kitkat source. Which mean it's impossible I think (my friend said that)
PS: Firefox OS has been dead last year.
View attachment 3872464 View attachment 3872465I again sat down at my Sailfish os port and have fixed some errors and comical he it at build without breaking what was always my problem one can hope maybe it will work
