Compiling AOSP

I cant seem to find any work around to compiling ICS or greater on a 32 bit linux system. As I understand, this is not supported anymore(atleast from 2.3.x and greater). I have a 64 bit windows computer though. Would any developer chime in and let me know what they would do?
I was thinking of just running(dual booting) ubuntu on my newer windows machine but did not know if this would work for this purpose. I really just wanted to build my own jb rom from AOSP and gradually expand my knowledge from there. Thanks for any input.

It's not recommended that you try building on a 32bit machine though there are modifications listed out there that *might* allow you to build AOSP from it. You are perfectly capable to dual booting Ubuntu on your Windows machine and that'll work fine. Even a virtual machine would work.

i first tried a virtual machine, that actually was harder to set up, it needed bios correction, network stuff, shared folders, guest extensions, cpu blablabla. in the end a single build took like 8 hours and the pc got so busy that i could barely move the mouse so the whole point of a virtual machine was kinda moot. installing ubuntu was easier than i thought. i wouldnt go for the newest version though. i did that and installing oracle java on 12.04 was not simple, actually that was the most confusing thing i ever had to deal with and i know computers since i was a boy.

funny, the tutorial i got was two pages long lol. anyway, i got it working then, ics compiled flawless. along came jb, breaking in the end because of weird proguard EOF errors. that was the point i switched to 11.something, now it works again. :cyclops:

i havent had any issues with JB compiling on a few of my machines... so far. actually just sitting down now to set up my new build VM on my esxi farm... i think 16 cores + 16gb ram should do the trick....

thanks for the input. i was under the impression running ubuntu alongside windows was probably the best. i pretty much setup everything on my laptop, got to building the jb rom from source and it spit out errors at me. I realized that I was an idiot for trying it on a 32 bit system after numerous hours of setup
I am new to doing all this myself and definitely new to trying to compile my own rom. I have experience writing some code but for think or swim which has nothing to do/doesnt help me at all with android. Thanks for the quick responses. Thought it would be awesome to learn everything. gotta start somewhere.:silly:

Ubuntu at the ready?

With the release date of the Ubuntu phone Images announced, are any developers preparing to port it the the arc? I hope the spec can handle it as I would love Ubuntu to see my beloved Arc out!

http://www.ubuntu.com/devices/phone/operators-and-oems
minimal specs are :512 mb -1 gb ram+
4-8GB eMMC + SD - we dont have enoth storge we have only 1 gb....
1ghz procesor +

Will ubuntu pwned android?
Hmmm short term answer will be NO
But long term, we wont know

what is eMMC?

What if we use a mod like data2sd adatped for Ubuntu OS? Like the users of Asus Transformer, that used fast class 10 sd cards to dump all the system related files there? Will that be a possible solution?

It depends. You don't need to port stuff like data2sd, the best solution would be to mount some directories at the sdcard which aren't immediatly needed at boot. I want it as well, but I'm still rather unexperienced with porting os'es to ARM devices. I do know something about linux.
For example: In my (basically unused) Ubuntu installation (I run Arch Linux as main OS) 75% of the total 2.5 GiB is used by the dir '/usr'. If we could mount that on the sdcard, 1 GB is plenty for the rest. Putting '/usr' on another partition/disk is not that uncommon in linux, so it should work. Also, if you download applications, most of it goes in /usr. (other directories we have to put on the sdcard are /opt (some kind of /usr) and /home ofcourse)
Space is no problem. One of the problems is that the Xperia Arc runs on an ARMv7 processor, and the Galaxy Nexus (which will receive Ubuntu Phone on 22 feb) is ARMv9.

I heard that the processor isn't a big problem, as it should run on wide range of devices. Something about kernels or something...

'Big' is relative of course. We will need to compile everything for ARMv7, because I assume Canonical won't have repositories for every architecture possible from the start. If Canonical releases ARMv7 stuff from the start, the main problem would be to get the different components to work, just like an Android ROM. Ubuntu Phone will use Android drivers they said, so hopefully it'll work.
If there's anyone that wants this on their Xperia Arc S and wants to help as well, please contact me or post something in this forum.
I will try my best to get this up and running on the Arc, but I can't promise anything. I'm not an experienced developer.

i am ready to help, although i dont have any experience with these kinds of developement.
i have an lt18i.

I think we are waiting on ubuntu to publish the wiki page about how to port it to other devices, once its up then we can have a crack at it

It is published. unfortunately i cant sync those HUGE sources because of low diskspace left (for compiling which has been taken up by other projects). hopefully as i clean up, you may expect a build soon. I said may, not will.

disc space isn't an issue over this end, how big is it?
Edit: 15GB, thats a big download.. D:

Around 15 gigs I think. With more needed for binary compiling. It says so in the guide

Im on a 40gb download limit a month, and I've already used most of it up :/

i would love to have a port of this
but unfortunatly, i am not able to help, as i do not know how to succesfully port

Hello everyone, I want, just like you, Ubuntu Touch on my Xperia Arc (S). I'm willing to spend a lot of time on it, although I'm not an experienced developer, I think I might be able to do it. For the moment, I have no immediate plans to port it, I'm first trying to understand it better. I've already encountered a lot of possible problems, but thank Canonical that they have made Ubuntu Touch so easy to port. (based on CM 10.1, using the same display driver, ...)
I would like to have a list of people that want to help or test. I'm not a real fan of doing everything in a forum, so perhaps we could make a google project or so. What do you think?

As someone's who's just switched from a dual boot of linux mint / Windows 7. To Just Ubuntu, I would be interested if it were to come to our architecture, but I thought ubuntu needed dual core processors? And obviously HDMI won't be available.
Google Apps isn't native to ubuntu right? So what kind of ecosystem would we be moving to? Also there is no lockscreen which is a little concerning, but the device itself works like BlackBerrys new OS, which is nice.

Running Ubuntu Touch as host OS and Android as Guest os with KVM on the Nexus 10

Hello.
My name is Mario. I'm a computer hobbyist. Recently I've bought the nexus 10. This project wants to virtualize android with kvm on top of ubuntu touch on the nexus 10. Someone has already did the most of the job,as you can see here :
http://www.virtualopensystems.com/media/chromebook/chromebook.pdf
they have used the arm chromebook,but IF I don't get wrong,it uses the same board,the exynos 5 with 2 arm cpu's. The only difference between the arm chromebook and the nexus 10 is the boot procedure. Virtual Open System did a proof of concept. They did not complete the project. In particular these features are missing :
Guest Sound support
A way to assign USB devices to the guest
Hardware acceleration
chroot integration in the default OS to achieve better integration with ubuntu
so the project that I would like to start wants to add these features to what virtual open systems did right now.
I know that usually Android run as Host OS and Ubuntu as guest os,but I think that Android is not a secure / powerful OS as Linux. I don't want to use it as HOST OS,but only as GUEST. Tell me what's your point of view. Thanks.

I've been wanting to a Linux tablet for years. I'm actually holding out for the Microsoft Surface Pro to liquidate stock for $300 or so if that ever happens.
The problem I see with Linux running on the Nexus 10 is its 2 GB of memory, especially for any type of VM you want to run.

But yes, this project of running Linux out right on the tablet could work very well with a stripped down OS so not to take up too much room.
I really wished Google put a memory card on these things.

Looks like someone from Samsung has done something like this with the Xen port for ARM
http://vimeo.com/78023395

Technically speaking,which kind of way do you like between the multi-rom or the virtualization solution ? And what's the best virtualization tool between KVM and XEN ?

Someone is interested to work on this project ? It could be posted on Indiegogo..

d me going there with that headline,
im keen to try ubuntu touch on my N10,
I would think ( im not a android or linux , or any other kind of prog/ eng.) that a dualboot or multirom solution would be better than virtualisation, esp on low resource machine. each rom runs on its own so no sharing of common resources?, just my uneducated guess, but Ill keep an eye on this thread,
like to see what the final, or working solution is.
great efforts , thanks

I'll save you the trouble... You flash the entire ROM over your firmware (don't worry, you can revert back to Android by flashing the firmware back).
When I ran Ubuntu Touch on my Next 10, it was... HORRIBLE. The extreme lag and performance issues made it utterly useless. Completely useless. This was about 6 months ago.
Went back and am running latest Android now, nice and speedy.

Tried Ubuntu touch as well. If Touch had been a full x86 Ubuntu experience, maybe I'd use it for a while. But it's Ubuntu with even less software than regular Ubuntu/Lunux.
So back to Android. ��
If you want to try it you can follow this guide:
https://developer.ubuntu.com/en/sta...installing-ubuntu-for-devices/#install-ubuntu

Any hope for native linux in the near future?

We already have the ability to boot multiple ROMs and plenty of kernels available. Ubuntu Touch is not being built because it is based off of CM10 (4.2) which flo/deb never ran and as a result are unsupported. However, what is stopping devs from using the kernels available to boot full ARM versions of ubuntu, debian, arch or gentoo? I've looked at the nexus 7 2012 and there has been plenty of such development, even sooner after its release. Is this nexus doomed to solely run android due to the qualcomm processor it possesses?
Also, please note, I'm not looking to run linux INSIDE android (chroot method). That is possible on just about every android device known to mankind and nothing special. I want to run linux as a ROM. This has been previously accomplished on popular tablets like the nexus 7 2012, note 10.1 and the transformer prime, just to name a few.

Bump?

Do you have any links regarding a native linux implementation on the 1st gen Nexus 7? I'd like to look into it, sounds interesting.

I found two separate attempts to bring Linux on this tablet:
wiki.merproject.org/wiki/Community_Workspace/Tegra3/Nexus7 and github.com/Bogdacutu/flo-Fedora
None of them are successful yet - I guess display (or any other debug output method) is a blocker here. AFAIK Tassadar has managed to make an UART cable - delta.fratler.de/68-raiders-lost-uart/

Managed to run Bogdancutu's flo-Fedora (updated to F20 though), but I cannot get the screen to work. Any ideas/tips?

Mind posting a link? I can't find the thread on xda.

Still chroot, not exactly native, but the screen is run through X11 as opposed to a vnc server. Pretty good actually.

Really not necessary, the nexus 7 2012 forum here on xda and a google search will yield that. Completely different SoC and other peripherals don't let the tutorials carry over.

There is a small addition there that flo's version boots but display doesn't work. I've also found attempts to run graphics via libhybris (build.merproject.org/project/packages?project=home%3Acxl000%3Anemo%3Adevel%3Ahw%3Agoogle%3Amsm%3Anexus7) but I never managed to try Mer.

Hi guys.
I managed to get the basic linux kernel v3.16-rc6 to work on the Nexus 7 2013 (WiFi).
Turns out the debug cable I originally used (delta.fratler.de/154-nexus-7-uart-unlocked/) works perfectly fine.
I use the qcom_defconfig as base and will work my way up from there, creating a n7-device tree.
In order to get linux to talk to you via the serial port, you'll need a couple of fixups though.
Namely:
codeaurora.org/cgit/quic/kernel/skales/plain/atag-fix/fixup.S – this is due to the fact that the N7 bootloader hands over the wrong memory-mapping in its ATAGS (shifted by 2 MB)
Compile it with
gcc -c fixup.S -o fixup.o; objcopy -O binary fixup.o fixup.bin
Then merge the fixup, kernel and the dtb:
cat fixup.bin zImage dtb > bootImage
Next up, to prevent the console from freezing, you need to grab this file from the qcom repo over at linaro:
git.linaro.org/landing-teams/working/qualcomm/kernel.git/commit/a751c4d71e792784f4d9f399bfda04007a6f403d
Note that the UART-port has been renamed from ttyHSL to ttyMSM.
Here's the kernel-config I used (based on qcom_defconfig): paste.debian.net/113411/
Once the dts resembles something remotely useable, I'll post it as well

Unfortunately not yet.
I'm currently having some issues getting USB to work. The patch to implement the QCOM PMIC8921 extender's GPIO ports has only been submitted 2 weeks ago and I have yet to figure out how to implement it in the devicetree - If anyone can give me some pointers to that...
I'll set up a github repo for the linaro kernel with the Nexus 7 dts this week. Once I have some rudimentary support (USB, eMMC, WLAN), I'll start upstreaming.

Still no real progress but things on the linux-arm-kernel mailing list have been moving pretty quickly so I hope we'll have a decent patch set within the next two weeks or so.
In the meantime, I wrote up a basic guide to get things started if you're interested in porting a vanilla kernel to the N7:
delta.fratler.de/168-nexus-7-kernel/

Trying Complete Linux Installer from Play Store made me personally conclude any conventional desktop Linux UI at the moment is unfit for using on gadget display. But I wonder what takes so long to simply wireless mirror screen dual view and extended desktop to dlna, Chromecast, etc 3rd party display. Phone/tablet can then function as desktop/laptop too with ultra mobile workstation also.

[Q] Anyone tried building/compiling Android for Windows RT devices?

Recently I installed Windows 10 RT on my Surface RT.
I think it's better than the Windows 8 RT and most people can agree on that.
Even after having W10 OA, there are not many apps available for this device.
I was wondering if anyone successfully built a version of android that ran on ARM Windows devices. I would like to build one compatible for the Surface RT but there are no kernel sources or device trees available. Also, there is no way to flash it with a conventional flash tool. Therefore, it cannot be built this way. But has anyone tried compiling android x86 but for ARM?
If yes, in which way did you build it?
Or if you built it in another way, in which way did you build it?
I am very interested in building a version for our Surface RT so we can finally get somewhere and get support for almost all of the apps in the android world

Sounds like a good idea, another option would be to look into the Linux4Tegra side of things, I'm not sure if it supports the Tegra 4 in the Surface2 but if it does we might have some interesting things to draw out of it...

Actually, there are suprisingly still people working on linux: https://forum.xda-developers.com/wi...-secure-boot-linux-surface-rt-t3653848/page12
First we have to get linux and then we can adapt the kernel and drivers to run android. There are very similar tablets running android like the ASUS Transformer Pad TF502T. If we use this kernel tree and build a device tree, we should get it working. I would try Lineage OS and TWRP. I think we can get maximum android Nougat for this tablet, after that, because of big kernel changes on android oreo+, we have to modify it even more. Forget about android X86. It's not a great idea.
I have compiled android custom roms before, but with all of the sources ready. In this case, we have to build a lot.
CrackTheSurface said:
Android is only a colorful touchy surface which is based on Linux, so at very first we must get Linux running.
The SoC(System on Chip) Tegra3 has Linux kernel mainline support so driver support shouldn't be that much of a problem (I am an optimist :fingers-crossed. Display output should also be possible as far as i know it uses Display Serial Interface (DSI) and is directly connected to the SoC.
The attachable keyboard is connected via i2c HID, which has also Linux kernel suppport. HDMI should also be supported out of box by the kernel. Touchscreen, WiFi, Audio, Bluetooth are the main problem points.
But now must start getting the kernel to run with an command line interface (CLI).
And installing the nvidia graphics drivers and multimedia codecs
