Compiling Android versions and kernel to Tattoo

Anyone knows where can I find informations about to compile CyanogenMod and kernel for Tattoo from source or other packages already configured for Tattoo? I want to help working in camera and FM development. I have a little experience in Linux, beagleboard and arm7 (lpc2368) programming, maybe I can help, but at first I need to learn the basics to help the working in camera and FM drivers. Sorry about my bad english. I have a lot o time disponible to help.

Take a look at CyanogenMod Wiki: http://www.cyanogenmod.com/wiki-page

I cannot find informations about the compilation process in HTC Tattoo. Can I use the process of wildfire as example?

The procedure is basically the same for all phones. You will need a vendor specific config for the Tattoo though. You can use mine from git if you want.

Thanks. I will try to compile your repository for learning. I need to download the android sdk for compile or just the 3 sources?

Follow the instructions in the CM wiki, and you will get the whole build environment, everything that's needed to compile. You will also need to download my files, either as a zip from github, or use git to clone it. And then put it in where the other phone vendor configs are - device/htc for HTC phones. Just poke around a bit and you'll understand it eventually. Takes a while to get familiar with how things work, what is where etc, so don't expect to master it in one day.

@arco: a little question, can I compile a rom and use your kernel without recompile it? I have a celeron processor and need 1 hr and half to compile a kernel

If you need one hour for kernel, Cyanogen will take 1 day. But yes, arco has kernel precompiled in his git

1,5 hours to compile the kernel? Takes about 5 minutes for me, and building the whole CM sources takes about 0,5 hours. I have an i5 [email protected], using 3 cores in an 64-bit Ubuntu Virtualbox environment.

There is any book about the android porting? I'm really confused about all the process necessary to work with the files. I never used git before, as I understanded it download just the modificated files right?

Meh, don't bother with my CM9 port, the code for that build is ancient in technological terms. I'll be compiling CM10 or AOKP JB for you guys next month when my bandwidth meter restarts. I waster a LOT of bandwidth trying to sync the CM10 code and having it run into a fatal error at the end. Such a piss off.

I like Ubuntu a lot. I've only used 11.10, and 12.04 but I personally prefer 11.10 due to the fact that 12.04 is "only experimentally supported for compiling ROM's and not guarenteed to work". I also find 11.10 to be significantly more stable and smooth than 12.04, but it could be because of my older computer and processor.
If you're good with technology and computers (Which you most likely are since you're on XDA) then you should have no problem learning how to use Ubuntu. There are a little bit more quirks in Ubuntu than in Windows, and the problems typically have to be fixed in the Terminal, but it's not that bad. I personally enjoy using Ubuntu, I found it to be very easy to learn how to use. (But I'm a major nerd )
Edit: If you want to know anything else about Ubuntu, let me know and I'll fire up my VM.

My pleasure I've read them all, and tried out a majority of them myself. Some work, some don't but they all teach you valuable lessons and are worth reading. Not all of them are for Sense ROM's, only some of them are. I also really want to compile CM10 which is why I also have a lot of AOSP links. Some are also app tutorials, I'm also trying to learn how to write apps.

That's an impressive list, thanks for sharing.

Well, you need a lot of work to get a working build, as i currently compile CM9 for SXL.
Recommended distros: Ubuntu 12.04 Precise / Linux Mint 13 Maya with Cinnamon interface to have the best linux experience << The best linux distro i ever used
Packages: Well, you need to check the Paranoid site to download the repo for ICS or JB variant of source-code.
Commands: Lots of commands, there are tutorials online. Example >> here
After this, you will need the device tree for SXL, i have one that is deprecated (not updated for some time), it does not work the variant uploaded here, but i will upload it.
You will need the vendor files, i also have the files but as the build of CM9 don't work, i haven't upload them anywhere untill i can get an at least experimental build that boots
Link for android device tree for sxl by me here
There is a lot of work and there aren't any specific guides on how to do this, you need to join communities and be a pain on the ass for them untill you learn how to do this.
I hope this helps anyways

thanks a lot I think I start tomorrow I'm a little tired

Hi just so you know you won't be able to compile Paranoid Android for ICS from source as it was never released.
If you can get JB to work then you will not only be a hero but also be able to use Paranoid Android source

I have a problem I can not download the sources of the paranoid in any way
help (or build the sources normal Android?)

Did you follow a guide how to set up the environment in linux? Or Mac.. the way you can download sources is git clone and then the git link. There are many guides on doing that part. Also when I download source it times out in a 4 mb/s connection and I need to use a better connecyion

aa ok but the guide I was reading did not say that it was necessary to clone each of the sources piece by piece, but he said to use a single link.
I have linux mint 14 with cinnamon (from the 13 consigliatami lextmazter I do not work)
both in Italy and in spite of my connection is approximately 16 mb / s (88% above the national average)

I do not recommend Linux Mint 14 as it is new edition, based on new Ubuntu version 12.10 if i remember good, don't know for sure, that's why, on Ubuntu 12.04 building is supported, even though on some guides it is said that on 12.04 it is experimental, well, it was, now it should be stable.
Also, if you want to port things like Paranoid or PAC you should start with AOSP or CM9 or AOKP, to put it short, versions that have guides and source codes on their sites. In my opinion CM is the best thing to start with, that's why i started CM9, after that you can easily port every 4.0.4 AOSP based ROM.
The same thing applies to JB, if you can port or build AOSP or CM10, you can port every JB AOSP based ROM very easily following only a few basic steps, that's how things work in this hood
Off-topic: I was a little distracted from building/testing/devving because of the school affairs, but today i will resume my work on CM9, if things work well, i will have a bootable build this very evening.

same as lexmazter, sound correct. the hard part is build CM9 rom, rest is pretty easy.
Lexmazter, i am about to try take a ramdisk from cm9 primou and make changes in every lines and see if i can get it to work with runnymede. if it does we will have a working aosp bootimg. i have compiled a zimage from source and it works with wifi and bt and so on in sense rom, also zimage works with cm9 with wifi.
lexmazter, can you please take a bencmark test with antutu 3.0.1, the new one, and post screenshot of the score and wich rom you are in ? they have made the test much diffrend so score is diffrend in 3.0.1 than older , so i have nothing to compare it to

5941 no OC with LTX Kernel v0.7 and Sense 3.0 by fshami, also, i think i found the right ramdisk for now for CM9, it solved the dalvik-permissions, now i still need to boot the build, still trying to figure what is wrong here and why it hangs after Android is upgrading... >> Starting applications.
I can work more on my device now as i have a cheap second phone to use if for calls and sms.

so then I decided, when I start buildare the source of AOSP Android 4.2 jellybean I think it's easier for me to start.
I had to use because the new mint old man crashed always

As a recommandation, i would recommend building AOSP 4.0.4, it is easier to start and has more chances of working, after that, you have the experience and the headstart to work on 4.1 and only after that on 4.2.
Just start with baby-steps, it is easier and increases the chances of success.

Well, i recommend this because i'm still building 4.0.4 and i haven't successfully booted a build, so that's why i say this, because if you get the 4.0.4, in short terms, all you need to change for 4.1 is the graphics driver, but for 4.2 i don't know for sure, too new for me and i'm still trying to get 4.0.4 to air

then my kernel is not so bad 5838 with sense 4.1 v. 1.5.1 and still missing some improvments
which ramdisk are you using, zimage from stock rom should get it to boot, but the ramdisk as you know need to be changed to cm9. when you compile from source it should also make a ramdisk that will fits the rom, i think it is best to check what the diffrence in the new ramdisk and the old one with VM errors and then fix them, perhaps it will boot then ? one specific compiled by you ? post a logcat in your cm9, had also some bootloop in my cm9 port but got it booting.

just enter the irc channel, will talk more there, no need to spam the forum with this.
The boothanging is because of the audio, the ramdisk is good, i use the LTX v0.7 zImage and ramdisk from stock edited to fit the build.
Also, the ramdisk is not made with the build, maybe if you compile the kernel with the rom, and for this you need to put the kernel online and othe things, and because of proxy, i can't and won't do that. For more details, like i said, find me on the irc.

[Q] How to port I9300 roms to I9305?

Hello , I'm very disappointed of the interest of the developpers for the LTE variant of the S3 so i wanted to port i9300 roms from myself , according to hardware , the only changes are the modem and the ram right ? So how could i port these roms ? From no specific knowings , i'd like to at least learn how to do it without big risks of brick so help please .
Thank you and sorry for english mistakes if i've done some.

this is not a easy question for random guys like me with almost zero knowledge about developing, although on the other hand a developer could simply explain how its done by f.e. making a thread about porting roms specifically to our i9305 in noobs language (if possible) but i doubt that this will happen, as it is very much time consuming and a lot of thinking and typing work. personally i think a thread like this would bring some life into our i9305s threads, dont you think so..?
to get you already started with some learning and discovering for yourself, read further..
the best method for porting roms is IMO building from source, but this is not as easy as it sounds..
first you will need to set up a build environment. I assume youre using Windows OS, now if you got a 64 bit system this is exactly what you need.. fortunately for you and others there is a custom branch of the Ubuntu OS thanks to @sylentprofet to use with Oracles VB/VM (Virtual Box/Machine) already preconfigured for building or porting roms (both require building/developing experience though) all you need to do is download the source and commit, fork, cherry-pick etc. if you decide to step into the android development world, you will learn more step by step however having some basic knowledge like terminal commands and git commands would be useful.
Also you need to get familiar with github and how it is used, check out here
I recommend lots of research though before actually taking any actions!! all these things will make you feel :silly: at times, but do not give up! for there were is a will, theres a way
good luck :good:

your welcome bro :good:
i really have no idea about how linaro is used in combination with kernel, you really have to google that one or get in contact with a dev. willing to help you out i think the kernel is automatically installed with your build when youre initializing/syncing repos and with commands in terminal its executed to build it. you can of course compile own kernel with modifications but as i said it needs lots of research, wish i could help you..
try for now some basics with the guide for gaining more experience and who knows what you will be capable of in next 2/3 months or less

CM 12.1 For S2

Could someone educate me on what it takes to get CM 12.1 on to the S2?
I understand that you have to root, install TWRP, and flash the ROM but who actually puts together CM 12.1 rom together and makes it compatible for the S2? Is it the official CM team or a developer on this forum who takes the time and energy to put it all together?
Thank you for your help in educating me......

There is no Cyanogen for our tablet for the moment
You can check here : http://download.cyanogenmod.org/

So it is the CM Team that takes the time, energy, and resources to put it together for the S2?
I will keep an eye on the CM website and hope they put something together soon. I wish I had someway to contribute but my skill set is very limited.
Thanks

No.. it takes someone with enough knowledge to build it for our hardware. I've never done it, but I'm attempting. Learning as I go... emphasis on attempting.

Okay - That makes sense.... I will help test if you get to that point.

Would be nice with cm12 but probably with lots of drawbacks. Samsung won't release source code of drivers and could be problematic with exynos nor will fingerprintscanner work.

CM is always buggy and lots of features wont work or plain buggy. Bloat is very minimal and works quite smoothly stock. Dont blame you if you like the "fun" of constantly flashing roms and waitkng for bug fixes.

Hey there. As a dev myself I will explain you the difference between official CM builds (build = the ROM) and unofficial builds. Official builds are made by the pros. The guys that are in the CyanogenMod group. They know how things work and patch them due their high knowledge. They will try to update the ROM regularly and fix it as well as they can. Then there are the unofficial builds from people like me. It depends what your skills are and with what board you are working (Exynos is a pain in the ass). Not to forget what version of android your device is currently running. Unofficial builds can be buggy and could take some time to get fixed. However devs will listen to the feedback of the community too.
