Hello,
I believe a lot of us would like to do it, so let's please describe here how-to:

Excellent initiative, I could write a short howto for Arch Linux later.
But one thing though, it might be a good idea to mention in the first post that you can't actually boot a custom kernel yet.

Indeed agree, but to try we need to have it!
My topic about compiling kernel sources has already many infos so do you think another similar topic is really necessary ?

Your thread is excellent but I'd guess that this thread would be more oriented towards "hand-holding", really basic guides. Your topic was very broad requiring going to the android developers site and reading their docs on cross-compilation. Gathering that info into easier guides could be beneficial, if not to demystify the process.
As it stands right now just compiling modules seems almost insurmountable. But if the information needed could be condensed into simple guides it could show that while it takes considerable time and effort it's not an impossible task even for developers not familiar with cross-compiling kernels.
And information information on setting up cross-compilers for Win, Mac and popular Linux distros is nice to have available in an easy to find topic anyway.
IMHO, the easiest way to make modules would be a virtualbox image already set up with arm gcc, kernel sources and X10 kernel config. It's a long process to set everything up; virtualbox makes this easier and cross platform.

Yes, french for me is a bit difficult
Ok i managed to make Ubuntu on my Parallels, just finished with the gcc. Let's see how it works.
Maybe i will share it.
kernel config is included in the /etc folder if I remember well, hope it's the same for the mini X10
It's actually in /proc

Hi zdzihu,
I managed somehow install arm gcc on my Ubuntu. Now it's time for the tools.
So i would like to ask what config should i use arm v4? V5?
I am so tired with this linux things, but finally at least the demo busybox compiled well
So i tried to compile with arm-v5te config but for flash read (which is normaly working) it says
Code:
# ./dump_image system /sdcard/tt.bin
error reading system: Inappropriate ioctl for device
My task it not to run flash tools available, but my own, to compile all myself, to try to do the trick with the CPU to accept kernel, that i compiled.
Thanks.
The Snapdragon is armv7 compliant, so that should be your target.

Are you using that tool to build the toolchain? In that case it might not have the option to build for that arch. The best way to make sure you get the correct one is to build it manually from scratch.

Looks like there is no other tut to build the toolchain. I searched days and nights to find something working.
I even compiled bysybox with it and it works on my x10!
But i found some sources of flash backup, called nandtools, compiled them well, no errors but the exec files are 4x bigger than the precompiled ones... And it makes the IOControl error..
the NDK won't compile, it requires Makefile or Android.mk and those are real headache to learn.
The Makefile from the archive is not compatible with NDK's make system and so on...
And so 2 weeks..
Pufff.. I am so tired if just linux things
Any hand?
Hi there, ARM is backward compatibile so compiled for v5 should run just fine. Problem must be somewhere else... I'm at work at the moment so I can't help much
By the way, there was some kind of dedicated flash tool posted already HERE, maybe you could check with jerpelea for re-upload?

You see, i need to compile mine, i have enough tools here already working, but my task is to compile my own and that's why i need a toolchain.
NDK is ok for the kernel, i compiled it already. But the native applications are not supported fully. Like write is deprecated and you can't use this function, and lot other limitations. So independent toolchain would help.
That's the point.

hey everyone, I've been with android since release on the g1 and have followed it since. but now I'm tired of being just a user and want to learn how to develope roms. I would rather have some one teach me first hand, but links to some places that helped you would be great too. So again, Im looking for a dev who would want to teach me, if some money is wanted, that's fine. thanks for reading. reply here and/or PM me. I am very serious about learning, I dont just want little tips/tricks or pointers.
Edit: I have a bit of skill in C++ and Java, but nothing too significant. I lost interest in writing programs, same with apps, no interest, everything has been done over and over again.
I have created a site specifically just for this. I have a link in the signature but feel free to just click here @green rom project

Some sort of a guide to developing roms. even porting. not an "all in one" guide. thats unrealistic and would most likely suck, seeing as its such a broad subject.
that site, is... i dont even know. not to insult you, but i found it to be useless. the single guide you have on there is for setting up the htc kitchen, which i figured out in 5 minutes on my own. I would suggest making a "Guides" section of that site, so it isnt JUST forums, and adding, well, GUIDES. you pointed me there to help me, but there was nothing on the forums even close to helping me.
What os are you running? Have you succesfully compiled the source yet either aosp or cm?
CyanogenMod's github is a great place to learn repo the source. Read the commits @ github.com/cyanogenmod all commits are commented to make reading changes easier.
Aosp is also on [email protected] github.com/android building aosp can be more tricky.
Cm is aosp with many custom packages included to see what is and isn't aosp [email protected] github.com/CyanogenMod/android
default.xml contains references to what packages are cyanogen and what is aosp
Either way you need to start by getting very familiar with
github.com/CyanogenMod/android_vendor_cyanogenmod
Look in the products folder at the .mk files
and how they are invoked by core/Makefile in
github.com/CyanogenMod/android_build
Also pay attention to build/envsetup.sh

your last post was quite helpful. Barely anything at all.
best bet start by getting the source to compile... sounds simple but can be tricky
most importantly get to know ~/android/system/build
you can't produce a custom rom without understanding when and how everything is compiled

"Dont forget to hit the thanks button if i helped you"
I'm new to the Dev world myself... I've done a lot of reading and research and I've gotten to the point of building and modding Roms to contribute to the community here. I've only done rom's for the Eris, which isn't as complex as some of the other devices, but I'm willing to share my knowledge if you need it.
The basics you will need:
1. Linux (I've tried doing this in windows, not worth the hassle!), either ubuntu or linux mint work well (Mint is a windows "like" os, so it might be easier to start with that).
2. Android SDK Kit (You can google it)
3. APK Manager (If you need to decompile APK's to make changes, this tool makes things a lot easier!)
4. Android Kitchen (A must if you are porting and to keep your Rom's cleaned up!)
5. A working understanding of XML and some java code is extremely helpful!
6. Time and Commitment! Devving, by any standard, is a time consuming process! You can easily make a Rom, but keeping the masses happy requires updates to nightly sources and time to rebuild what you've started!
I've spent so much time updating, compiling, modding and theming that my family voices plenty of complaints! But, the reward of building something that works and seeing others benefit from your creation is well worth the effort! Balancing your time, if you have a family to consider, is key to succeeding with this!
If you'd like more help, send me a PM! I'll work with you as much as I can!
I setup the kitchen, as i previously said, but didnt find any use for it except maybe adding minor features to a completely stock rom. i have linux set up with the SDK. i just dont know where to go from there...even compiling from source

Sent you a PM back, bro.
Having Linux, SDK and the Kitchen setup gets you about 75% of the way there!
The basic steps to compiling from source run through the Terminal in Linux. You will need to pull in the CM repository (the link jbirdvegas posted will give the instructions to do that). Once the repository is setup, you will need to load the proprietary files for the device you're building for in order to sync the correct source. (repo sync -j16 will sync the source and build your folders for compiling). You will need to plug in your phone through USB and extract the proprietaries through ADB. Example, my build location in Linux is "android/system" in that folder there will be a device folder with folders for each device brand and build. My eris is listed in CM as desirec, so my drive folder location is "android/system/devices/htc/desirec". In order to pull my proprietary files, I would have to do the following:
1. In terminal; "cd android/system/devices/htc/desirec" (This puts me in the correct build folder)
2. su (puts terminal in root) - type in password
3. "./adb kill-server" (shuts down adb)
4. "./adb start-server" (starts adb)
5. "exit" (puts you back in standard terminal)
6. "./adb devices" (verify your device shows - if you get ????????, adb did not start right)
7. "./extract-files.sh" (this will extract the proprietary files from your device and place them in the device folder for building)
8. "cd"
9. "cd android/system" (puts you back in the CM build folder)
Once that's done, all you basically need to do after that is:
"source build/envsetup.sh" (Setup source build)
"lunch" (this will give you a list of builds - pick your device)
"make -j# bacon" (# is the number of processors your phone has +1)
The Repo Sync and Make commands will take time, but once you've finished the Make cycle, your Rom (if there were no errors) will be compiled, signed and ready to flash on your device. From there, you can use the kitchen to add "tweaks" to your rom (CM sources are usually pre-setup, but you can still add things like "data/app" access to your Rom).
Hopefully this takes you to the next step. PM me if you run into problems, I'll help you through it.
If you get abd shows your device as ??????????

jbirdvegas has it right on the adb correction if your device isn't found. I'll look for setting up the rules and post the link a little later.
Glacier doesn't have instructions yet, but there are CM builds for it. If you follow the evo instructions that will get you setup. Just replace supersonic with glacier to get your device established. There wasn't one for the Eris, either, and the EVO instructions are what I used.
Also, if you're building for GB and you're on a 32-bit system, it will tell you you cannot build it. There is a bypass; I'm using a 32-bit system and just removed the "end" statement in the make file. My builds work just fine, so bypassing the environment won't mess up your builds...
You can download the ROM files from here: http://goo.gl/ETPsm
Sorry I haven't had the time to package it for CWM. Hoping somebody here can do that for me.

If you don't know how to flash it, then it's best for you to not even try.
It's an ALPHA (or even before an alpha) made from SDK image ported (quickly) to the Nexus One.
This means a lot of things are not working, it's not stable and can not be used as "main rom".
Just wait, "usable" ICS roms will come but now it's just too soon.

Too many things to list that's not working. Here's what's working: touchscreen, hard buttons, battery indicator, accelerometer.

Well maybe because people don't know how to do it. And as for the current rom the major problem is the hardware acceleration and the camera. Maybe We can find it (The binairies) at opensource.samsung.com
It should be easier than phones because you don't have to worry about not screwing with voice, data, and stuff like that. Just get it on and get all the apps working correctly. Radios are always the hardest.
I've also been triyng to compile the source for the player but i wasnt able to do so, the thing is that the source compiles fine with the pre-adjustments it comes with, i mean the androidboard.mk ( i think thats the name of the file not sure), but when i changed the variables for a armv5 build, which is the core of the device and the ones that comes in the same file on the opensource.samsung soource, it just doesnt compile and throws some kind of errors about some libraries that i didnt touched. i dont know what i had been doing wrong.
I Also found this video in which they show whats in every folder, and how to build and add packages from source to the build:
http://marakana.com/forums/android/general/269.html
This is a detail process description from the official android site to build from source, very similar like the one zaclimon found:
http://source.android.com/source/initializing.html
The source from samsung doesnt have all the drivers, just the alsa audio driver, i guess we gonna have to find a way to get the binaries like cyanogen did, maybe get some scripts they use and try to do it ourselves:
http://wiki.cyanogenmod.com/wiki/Sa...le_CyanogenMod_(Linux)#Copy_proprietary_files
it is done through the adb, but the thing is to get those files, maybe we could ask that fellow some help for this step, since he has the experience.

The core is a ARMv7 right? because the hummingbird processor is a ARMv7. Maybe it did failed because of that? I found the gpu drivers from the opensource. Check in the kernel folder. If I can give you the gpu file if you want. Well tell me what files you are missing i'll find to give it to you. (Well I don't know how to program so I try do to my best.)

Maybe it is easier than the official source, they modify the source and takes out some things that cellphones dont need 'cause the source it's made for all devices, so it could be smaller and easier to compile, i'm gonna try this port and let ya' know, it will take a while since the source it's huge
Would be great if a couple of us do it, if you can @zaclimon try it, you don't need ubuntu, if you know which libaries that command has (sudo apt-get install build-essential). I have debian and i compiled the source just fine, debian has a minimal installation (no X11) but to compile source you dont need anything else!

i'm willing to engineer a generic build, described in the video tutorial and making the necessary adjustments for the ARMv7 board...
this is my first attempt at compiling Android source, so maybe we will have something or maybe i will have a good ol' brick...thanks for the great tutorial and video @zaclimon this has definitely shed some light on porting ICS for SGP

Yes they are supposed to be there. But I have download all the source code of the firmware from opensource.samsung.com
Me and sodomywar are working with the internationnal version of the SGP4. If you want to join you're welcome.
EDIT: No problem for the tutorials.

Google is your friend
So this is where i'm at currently. I'm trying to compile and I got this error:
Code:
build/core/base_rules.mk:166: *** system/extras/ext4_utils: MODULE.TARGET.EXECUTABLES.setup_fs already defined by device/samsung/galaxyplayer. Stop.
Does anyone know how to remove that error?
EDIT: nvm I managed to remove this error.
Hi,
As a noob i came across a word related to android "compiling". What does compiling exactly mean?
Not very experienced with android but compiling usually means converting codes to executables

Zip->unzip
Compile->install
sony xperia ray
ics 4.0.4 rooted
stock rom

i do but i am not sure does compling mean making a rom?
Nono...see in terms of android.
Decompiling= breaking some files into many parts
Compiling=Joining the broken parts to get back the original file back.
Its usually associated with Decompiling and Compiling apk files to mod them or stuffs.
Dont worry we all were "noobs" once

It's not too different from the usual programming definition of compiling. When you write a programme, you write it in a higher language that reads almost like English (unless if you are a nut case/genius who likes coding in assembly). However, for a computer (in this case your phone) to run it you have to translate the programme into machine readable language first. This translation process is called compiling.

I am afraid that is not the correct definition of compiling. The apk file is just a zip file of media files and code. When you break apart an apk file all that you are doing is just unzipping. The codes are still inaccessible. To be able to read them humanly you need to decompile the codes, which is usually impossible. That is why people need to post source codes.
Compiling takes quite a bit of computing power and can take hours if your code is long. Packaging and signing an apk? Not si much.

phew........... dat was a lot... hahaha i read a tutorial here that says "compile a gingerbread rom" so will that tut make me a gb rom??
It should, just make sure it's meant for your phone

here's the link
http://forum.xda-developers.com/showthread.php?t=1598713
so what do u think?
That guide was for porting roms made for other devices using roms that already exist for your device. For example, someone has already made a cm7 rom for your device, but you want a miui rom. Since miui is based on cm7, you can use the guide to create a miui rom for your device. However, if nobody has made a cm7 rom for your device, you cannot use that guide to port miui rom.
If you read the guide carefully, it's just a while load of copy and paste work, hence not compiling. The guide teaches you to take advantage of existing work done by other people instead of starting from the scratch, but it can't teach you to build a rom from scratch.

i totally agree with you but in the start of the post the guy says "Android Source | Compile GB | Compile ICS | Compile JB ~ Thanks dastin1015 |- Building/Compiling - Durations" what does that mean? will the link to the tut help me make a gingerbread for my ics based device??
and last advice will porting any roms to my device has any threat to it like bricking???
I took a look at those links. The first link is simply what it says - the basic source code for Android. The other compile links contain instructions on how to compile the source code into roms. They do not teach you how to write the source code for different devices, which is the most difficult part of porting a rom. Anyone can learn to compile a rom from pre written codes. It's the writing part that matters. You need to find the drivers and other proprietary codes for your device.
The guides can help you get started on making a gingerbread rom, but it won't fix the hundreds of bugs you are sure to encounter.
As for bricking, there's always going to a chance that flashing a rom might brick your device.

thaknz a lot for ur help
To sum up in basic words, compiling is turning a code from a high language into machine code so the computer can read it.
Also , if you din't know what is compiling i don't think you should be making roms
