I've had a look around and I can't see much information on this.
Is there a decent guide, or can anyone post some information on how one would go about compiling a Froyo (or any other release) build from source?
I'm not daunted by the technical complexity and I have no problem putting together a VM to build in and in fact, I did that to build Chrome OS not too long ago.
From what I can see I would just create a git clone of the latest code branch and compile it, although it looks like I would also need some drivers. Where would I get these from?
Would my newly compiled image need to be signed somehow before I could install it?
I have a general understanding of what I need to do, but there are some gaps in my knowledge
Hope this helps,.... Pulser pointed me towards it,... I haven't had a go myself yet as I've been busy,....
Have fun,....

Thanks - that was pretty much what I was looking for.
I'm a bit pressed for time as well recently, but hopefully I can try a build at the weekend.

As a matter of fact, you've got an example how to compile for dream/sapphire on the android source website.
Read up.
Thread Moved to Q&A.
well that guide
well that guide is not for building aosp roms is it ?
can anyone help me to learn a bit more than android!
I heared about compile form source and biuld form source...And I can't understand what diferences between compile from source and port! can U explain easily?
for example should I want to bring superOxygen Rom in my x10 , should I port it with cm as base or compile form source?!
thx
for short:
porting means you are making rom to your device from another device, you will be just moving libs, editing ramdisk, etc.
compiling from source means you make a complete rom from scratch including programming own drivers, libs in some situations.
If source is avaiable fot superOxygen then you can try compiling it yourself, but editing, or adding your drivers is necessary, and anyway its harder than porting, but gives better result in fact because you can program everything to make it work and you aren't dependant on binary files like in porting.
When porting, hardware should be close to one you have in your X10, because most things will not work when processor differs, wifi modules, gsm etc. You take files from any X10 rom and replace ones that are with same name in another rom (oxygen here).
Thanks very much man!
I took your advices...it was good advices but what is your idea about this:
If I port Superoxygen from Nexus1 for my x10 and (use stable AOSP as base) , then can I say I make a superOxygen Rom?
compiling from source is how much difficult?! I'm 17...! , I have a link that teach compile from source... Is it need some Knowledges that is impossible for me?!
heh, im 17 too and I don't have much knowledge, but looking on pcfighter(a gt540 developer) im impressed, hes 17 too and does a great job, so it depends on time spent and interests
when you port oxygen, you can just say that you ported and not made it. credits go to the maker and you for just making it work on x10
I'm looking now how to compile for gt540 but can't find any idea how to make it strict for gt540 compiling from source tutorials are mostly for nexus s and nexus 4g because most of are just remade of what you can find on official android developer page and its easier. For unsupported device its even harder, you have to work with what you already have and add it first to sources then ... more things to do. I'm beginner with that too, just pulled sources yesterday and looking how to make it work :] so don't expect so much help in this way :]. Just telling you overall how this looks
For compiling you need to know Java and C programing language.

@mesaj! do you know c and gava programing languge?! ofcourse I worked c++ a little...
Thanks now I also know what the difference is.
In easy terminology. Compiling a ROM is building a ROM from the source code so it means you are building a ROM from the ground up. Porting a ROM to your phones means to take a ROM built for another phone and to get it working on yours. That's the simplest way to think of it. I have in my signature a guide for compiling a ROM. Oh and I'm newly 18

Hi, I've managed to setup a building environment from DerArtem git sources, now facing some strange behaviour hope someone can help me:
ten day ago I succesfully built all, now till about 3 days after repo sync I've got linking error on external/webkit, so after some googling I realized something were changed in CM9 sources. I've added in Artem's BoardConfig.mk this line
Code:
ENABLE_WEBGL := true
after that change all went good.
Is it the right way, or are there other patches to apply?
Another one:
before cm9-rc1 I could select full_betelgeuse from lunch/brunch menu now I have to write at command line: lunch full_betelgeuse-userdebug because full_betelgeuse is not available in the lunch menu (before it was the 5th choice)
Is there something missing in the build chain?
Thank you.
I can't help you but please share your ROM once you manage to get a working ROM with the latest CM9 build.

Hello there guys,
As we all know we only have 3? 4? developers for the HOX+ . And they are really doing all they can to help keep the phone upto date.
But as we all know they are all busy and can't update their roms that much any longer.
EDIT: Lloir already has a guide : http://forum.xda-developers.com/showthread.php?t=2187266 but I don't think he covers how to fix camera and gps and stuff
So! Is it possible to make guide on how to compile the rom from the source? I know tombridden and lloir already made a one post guide on how to build some roms but it was too specific.
I now have an extra machine (a laptop) with 500gb free storage and ubuntu as the main OS. It's quite powerful too with 6gb RAM and i7. So Why not use it to help the community while others are busy? In the meantime I will look around for some guides for other phones but I don't think they will help that much.
And please include the answers to those questions if you make a guide:
1- What to do to fix camera/GPS/wifi/Data/sensors ?
2- What approach should I take when compiling a new ROM. For example: there are no developers for PACMAN , how will it differ during compiling between it and AOKP/CM/AOSP .
I am talking about a rom that wasn't approached by Lloir so he won't have the repos for them. What to do then?
Thanks a lot and I can't wait to help
@Lloir @tombriden @PippoX3 @mike1986. and any other developer out there.
you can start by looking at XDA-University
The reply is correct. All of us moved first steps studying at XDA University.
Anyway the case is more complex than others.
For this device there are really few developers. Other device have a lot of support from constructors, many dev and the team-work result in a lot of kernels/roms to flash for the final user.
If you wanna taste the happyness for build a rom, I'll send you a guide to setup your ubuntu, download the sources and build.
But in this case, where enrc2b is not officially support, the things are more difficult.
You must have a minimal practical with java, cpp, android and kernel code (if so).
For the moment I'm in trouble to build an AOKP 4.2.2 with new kernel. I haven't device to try, 'cause the hard is build&&try continuosly.
Not the fact to have a pc turned on for hours and hours.... and the eyes&&mind open for hours and hours... but the patience to continuously try time after time.
Now I am in a dead point... many users like have S2W enable on new CM kernel... but.... the kernel won't!
Thanks a lot anyway. Thanks to @Lloir, @tombriden, @maxwen and alls who's workin' for this device.
Stay tuned....

That's what i did already. I set up the periphals/kernel/device info GITs and now i am looking for the roms, I found CM and stuff but I can't find PURE AOSP , does that mean i must download it and upload it?
I also have Oracle java installed. Do I have to have open JDK?

Now that we begin to have a solid CM base, will possible to build at least CM for enrc2b for noobs too.
And eventually "port" device/kernel" parts to others platforms. So who like e.g. PA can do...
If you agree, I can paste my personal appoints to a guide, from client setup (Sun java don't works) to the build zip rom.
Updated and corrected to last KK.

Hi all,
In short i want to modify Android 4.2.2 on my MK802IIIS to allow me to use an external USB WIFI Adapter. The one i have uses a Ralink (MediaTek) RT5372 chipset.
I'm not a beginner, but by no means an expert. I have compiled firmware for my Linux based routers. But compiling Android, or parts of, seems much more complicated. I only want to add support for a USB adapter. Do i need to build the kernel from scratch, or can i create a module? Do i need to cross compile a module or can it be "made" in Ubunutu and just copied across?
I have searched for a RT5372.ko file online, finding references to RT5370, but i dont think it's the same.
I downloaded the driver from the Mediatek website and proceeded to attempt to create a .ko file by making it in Ubuntu but it only created a RT5372STA.dat file. Does this driver need to be cross compilied for android? Also how do i turn it in to a module that i can just load into my currently installed ROM?
I have been poking around for a while so i havent covered everhything i've tried. I'd really like to understand how building for Android works. If anyone can answer any of these questions for me, it'd help me imensely. Or if there is a resource covering these topics that i have yet to come across please point me at it. I know there are a lot of very detailed How-To's for compliling but i seem to get lost with the amount of detail.
Many thanks
More info regarding my setup:
Building in Ubuntu 14.04, 64bit.
The current ROM appears to have been built using the Linaro 4.6.2 toolchain, so u have downloaded that, currently stored in /home/wriggerz/RK3066/Toolchains
Also downloaded the RK3066 Kernel Source, stored in /home/wriggerz/RK3066/RK3066-Kernel
The RT5372 driver has been extracted to /home/wriggerz/RT5572NEW
I've been mashing bits of different guides and suggestions found on other forums together to try and frankenstien this KO module. From within the drivers folder i ran the two commands below. From what i've read this needs to be done to specify which "Toolchain" and "Compiler" to use.
Code:
export CROSS_COMPILE=~/home/wriggerz/rk3066/toolchains/arm-eabi-linaro-4.6.2/bin/arm-eabi-
export ARCH=arm
Then i ran the make command like below to try and have the driver built for the correct Toolchain with the correct Compiler:
Code:
make ARCH=arm CROSS_COMPILE=arm-eabi-linaro-4.6.2
However i get the following response:
Code:
make -C tools

Someone knowledgeable will hopefully look at the steps i have just taken to rip it to shreds...... :fingers-crossed:
If not, is there anyone with any ideas of where i'm going wrong?
I think i've put this in the wrong section....
If anyone has to go out of their way to move it they have my sincere apologies.

First of all, I would suggest to recompile the kernel and the entire source code (like when building CM), it is way better than insmodding modules every time, and you have less errors to solve. I'm currently writing a guide about building Cyanogenmod to support awus036h wireless adapter, maybe I can have a look for yours too, shouldn't be too hard. There are two or there good references around, however I'm trying to out all of them together in this new one I want to publish. Hope this will help you too.
Don't download a .KO from internet, it's not going to work. You would not only need to build for the specific device, but also for the specific kernel, which may vary from build to build, that's why I recommend to compile the whole kernel. Please consider to download a ROM's source code or your device kernel.

Thanks for the helpful response Ciuffy.
Before i ask any more potetnially stupid questions i will do some research on that approach. I look forward to seeing your guide. For now i may be back for some direction.

I do like the ROM i'm on at the minute. NeoTV CR 2.0 (4.2.2), works really well, snappier than others i;ve tried and the benchmark results are pretty good too, but there are a couple of issues with it:
Busybox isnt installed and doesnt install.
Commands dont seem to work in terminal.
Now it doesnt really matter, as i wont be Insmodding the driver now, but it would be nice to have. How do i stay as cose to my current ROM as possible while re-compiling? Do i need to contact the ROM creator and ask them for the source? Should it be available on the web somewhere? Or can i "rip" it off the device? My main goal is to add driver support to the kernel from the drivers srouce files. But it would be nice to have busybox installed too. Was thinking i might re-comile the whole rom, but that be like trying to run before i can stand..... But, learning is amazing, and i learn best by doing!!
Main question: Whats the easiest way to re-compile my current kernel? Do i need source files from the ROM creator? I have asked but havent had a repsonse yet, but it's only been about 16 hours, not even that.

Definetely, you should find the kernel source code, I think you can find it on Github, I'll give a look at it. I honestly don't think you can reverse engineer the kernel and recompile it.
Edit: I can't seem to find it. It is also possibile that the source code was not released.

Stupid Question: Is the SDK the same thing as the source?
If so i think i found what i need to build from scratch here: http://www.cnx-software.com/2013/08/20/rockchip-rk3066-android-4-2-2-hdmi-tv-stick-sdk-leaked/
If thats right, i need to find a way to add the driver i found to the source so it's included in the compilation.
Boom, think i found my base... And answered my previous question. SDK is not source.

SDK stands for Software Development Kit, in other words the environment that lets you build applications and related for a specific platform.
So, you found the source you were looking for?

Sure did, i also now know which compiler i need.... arm-linux-gnueabi-4.7.
Now to find out how to add the driver i have downloaded to the kernel.
From what i've read i need to "make" the driver, cross compiling in the process, then put some of the resulting files in situ within the kernel source. (along these lines: http://stackoverflow.com/questions/11710022/adding-new-driver-code-to-linux-source-code).

Excuse me, are you then going to compile the enitre kernel? Waiting for your answer, there should be an easier way to do this.
Ciuffy's SM-G900F CM 12.1 spirit hath marked this way. Thank if helped your soul.
I was going to, based on your suggestion to compile from scratch, but i have most likely mis-understood what it was you were getting at.
Also, i have downloaded a bunch of toolchains and i have arm-linux-androideabi-4.7, but is that the same as arm-linux-gnueabi-4.7
Again, i could be barking up the completely wrong tree. Which is a shame, as i thought i was actually getting somewhere..... hahaha!

Yes, I was in fact suggesting you to build from scratch, thinking you could include modules for your adapter in the kernel configuration. However, I can't find what kernel module is exactly going to do it. I found rt2800usb, however I am not sure. You may try to include support for rt2800 and also build the kernel module from the driver source code, as explained in that link for example.

If by cross compiling you mean building the kernel module while also compiling the source code and then loading it in the running kernel, yes, as long as you downloaded the drivers compatible with the Linux kernel on your Android.
You can either use the instruction on that link on StackExchange, or follow the "How to build them?" section here:

Seems i've still got some stuff to get my head around. I'll re-read up and come back.
FAIL!!!
Tried flashing the unit with the ROM i was going to compile a kernel for. Looked to go well, but wouldn't boot past the boot splash screen. And after rebooting wouldnt boot at all. Obviously some fundamental incompatibility, or the fact that it cant handle the overclock....
Problem is i have previously broken the OTG port so i have no way to flash using ADB, not until i get a cable soldered in it's place.
Really just wanted to explain why i may be absent from this topic for a bit. I'm going to make some calls to see if any nearby electronics shops can do the job. Once done i'll be back.

In case you misunderstood: I just wanted to point out that once compiled the kernel modules along with the kernel, you don't keed to flash the kernel, only insmod the modules.
Hope you can solve the OTG problem, waiting for your response.
