[GUIDE] Get Android 2.2 source for n00bs

I did this in Ubuntu 10.4 linux that i installed on a 14gig partition of my laptop.
You can do this in VMware or make a partition of your HDD and download wubi.exe to install linux on your partition... its easier than installing windows. You can use this to help develop if you know anything, or as i have done, used it to get the uncompiled .9.png's to edit for themeing, bypassing the draw9patch step cause the guides are already there ready to go through eclipse IDE.
INSTALL ALL LINUX UPDATES THAT WILL POPUP WITH AUTO-UPDATER BEFORE GETTING SOURCE.
on to the good stuff.... open up the terminal and run the following commands
Code:
sudo nano /etc/apt/sources.list
Then add the following to the bottom by scrolling down with your arrow keys and pasting by right clicking, CTRL-V WONT WORK.

Code:
deb http://cz.archive.ubuntu.com/ubuntu jaunty-updates main multiverse
Hit CTRL O and ENTER to save and CTRL X to return to the command line. Now lets get the repo packages cached onto your box using the following command.
Code:
sudo apt-get update
install Java 5 SDK and all the other little packages needed to build Android with this command.
32-bit x86
Code:
sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind
64-bit x86
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl sun-java5-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev
Code:
sudo update-java-alternatives -s java-1.5.0-sun
Code:
sudo ln -s /usr/lib32/libX11.so.6 /usr/lib32/libX11.so
moving on
INSTALLING REPO
You can install repo tool any place in your path. We choose a bin directory in our home folder:
Code:
$cd ~
$mkdir bin
$export PATH=$PATH:~/bin
$curl https://android.git.kernel.org/repo >~/bin/repo
$chmod a+x ~/bin/repo
DOWNLOADING ANDROID SOURCE CODE:
Create an empty directory to hold your working files:
Code:
$mkdir mydroid
$cd mydroid
# Run repo init to bring down the latest version of Android with all its most recent bug fixes. You must specify a URL for the manifest:
Code:
$repo init -u git://android.git.kernel.org/platform/manifest.git
NOTE: using -b option we can choose which android version to install:
Code:
$repo init -u git://android.git.kernel.org/platform/manifest.git -b froyo
To pull down files to your working directory from the repositories as specified in the default manifest, run
Code:
$repo sync
NOTE: mydroid directory size grows up to 3.6G.
BUILDING ANDROID
Simply on top of your android directory execute make command:
Code:
$cd mydroid
$make
After some time it will finish.
We get the installed file list in this file:
out/target/product/generic/installed-files.txt
Also some images are created in the same directory: (system.img userdata.img ramdisk.img)
mydroid$ ls out/target/product/generic/
android-info.txt data obj ramdisk.img symbols system.img
clean_steps.mk installed-files.txt previous_build_config.mk root system userdata.img
We have built android source code but now we want to test it:
run the Android Emulator, which comes within the Android SDK
http://developer.android.com/guide/developing/tools/emulator.html
Download Android SDK
http://developer.android.com/sdk/index.html
Install Android SDK
http://developer.android.com/sdk/installing.html

ill post the location of the framework-res.apk drawables and stock app apks to edit for those of you interested in theming.

I appreciate the effort but isn't this almost the same from android central by gbhil?

Made this because of all the errors i ran into and gathered all my sources of research of linux commands like changing your $PATH and installing java after my machine wouldnt find it in the repository, or not being able to get repo installed. Im just trying to help. I would have sourced gbhil if i took it from there. And this isnt a college essay, work cited pages arent necessary, its a courtesy out of respect. Besides... my sources where from blogs and most didnt have anything to do with android. Just throwin that out there. ©

Assuming you've installed an openjdk-6-jdk package, you can override the normal build restriction of Java 5 by editing the file build/core/main.mk and changing the Java version test to match against "1.6" instead of "1.5". You'll need to do it in two places, once for java and once for javac. I never had to do this to build Cyanogenmod, but you may need to for AOSP.

Decad3nce, thanks for posting so fast. The funny thing is I figured it out within 5 minutes of posting but got sucked in to finalizing my source code that I am now just getting back to the post. There are several here in this forum that really help out and you are one of them. I am just now getting brave enough to start cooking but catch on fast. Can't wait to see what you, nfinite and beezy do to the wildfire port!

[HOWTO] Create your own AOSP 100% stock

EDIT: Just updated post 2 you probably want to read both this post and that post before trying to build.
you can skip the part of getting the official source and the cyanogen source by just doing
Code:
repo init -u git://github.com/CyanogenMod/android.git -b froyo
First some prereqs You must be using linux and building for an evo 4G aka htc_supersonic
Install the android SDK as instructed here: http://developer.android.com/sdk/installing.html
You will need JDK most linux distros have this in the respositorys.
Then just follow step 2 and make sure that you can run adb from any directory in terminal.
Now to the good stuff.
You will now need to open a terminal window and run the following as root
Code:
cd /usr/bin/; curl http://android.git.kernel.org/repo > repo; chmod a+x /usr/bin/repo
now as user do the following
Code:
mkdir ~/android
cd ~/andoid
repo init -u git://android.git.kernel.org/platform/manifest.git
repo sync
This can take FOREVER like 4-5 hours so you might want to let it go when you go to sleep.
Depending on how fast your computer is the following step can take a long time too
Code:
cd ~/andoid
make
This will build the source code for a generic device it should build everything correctly if you have all of the compilers and what not. If it fails just install the app that it is complaining about.
Now for the EVO specific stuff
Code:
cd ~/android/device/htc
git clone http://github.com/CyanogenMod/android_device_htc_supersonic.git supersonic
That will get the build files however you are going to have to edit them to get it to work.
~/android/device/htc/supersonic/BoardConfig.mk needs to be edited
Code:
TARGET_RECOVERY_UI_LIB := librecovery_ui_supersonic librecovery_ui_htc
TARGET_RECOVERY_UPDATER_LIBS += librecovery_updater_htc
should be
Code:
#TARGET_RECOVERY_UI_LIB := librecovery_ui_supersonic librecovery_ui_htc
#TARGET_RECOVERY_UPDATER_LIBS += librecovery_updater_htc
Some other files may have to be edited to your liking. Personaly I changed ADWLauncher to launcher2 and removed all of the cyanogen stuff.
Now to setup the build enviroment.
Code:
cd ~/android
cp ./vendor/cyanogen/products/cyanogen_supersonic.mk ./buildspec.mk
. build/envsetup.sh
lunch cyanogen_supersonic-eng
Now to do the building.
Code:
make CYANOGEN_WITH_GOOGLE=true otapackage ## if you want google apps (market etc.)
make otapackage ## 100% Open Source only!
By the way for some reason you have to inclued the otapackage even if you just want the .img files because otherwise it crashes at least for me.
Let me know if you encounter any problems and I will try to help.

UPDATES
Copy your ~android folder somewhere and replace ~/android in this tutorial with the directory that you copied it to. This will allow you to update the overlay when needed.
To add google files you will need to do this
Code:
cd ~/android/vendor/cyanogen
./get-google-files
This gets the htc files and I think taht it might be required.
Code:
cd ~/android/device/htc/supersonic
./extract-files.sh
To make a clean rom like mine do the following:
Edit the file ~/android/vendor/cyanogen/products/common.mk to your liking. I just changed the build name and rom version.
I added the files sysrw and sysro ad you can see in the file just put them in a directory and tell it where they are and where you want them. Also I commented out rommanager.apk as I don't like or use it. Also I use RA recovery so it wont work for me anyway.
Also edit the file ~/android/vendor/cyanogen/products/cyanogen_supersonic.mk
I chaged teh build number to the latest spring and removed the boot animation as I like the stock android one better (and it is faster).
YOU NEED TO do this if you want a keyboard...
edit ~/android/vendor/cyanogen/Android.mk and remove LatinIME!
Now we delete some files.
go to ~/android/packages/apps
delete any application that you don't want. You can optionally add program source code that you do want.
I deleted CM* and Protips
I also edited some code in Settings to remove Cyanogen stuff. Actually I took the stock android stuff an edited that with one little fix but I forgot what it was. Just try to build and it will tell you in an error message.

Really cool

Awesome! Thanks so much for posting this.

thanks dude!!

Thanks man.

question...
im having an issue with this step
Code:
cd ~/adnroid
cp ./vendor/cyanogen/products/cyanogen_supersonic.mk ./buildspec.mk
. build/envsetup.sh
lunch cyanogen_supersonic-eng
specifically (lets ignore the type in the instructions
Code:
$ cp ./vendor/cyanogen/products/cyanogen_supersonic.mk ./buildspec.mk
cp: cannot stat `./vendor/cyanogen/products/cyanogen_supersonic.mk': No such file or directory
$ find ~/android -name "cyanogen_supersonic.mk"
$ echo $?
0
anyone else having this issue?

So what is the difference between this and running CM6?
Will this avoid the market issues with CM6?
Once it's built, how do you get it installed on the phone?

Here is the link to cyanogens wiki how too......
http://wiki.cyanogenmod.com/index.php?title=Compile_CyanogenMod_for_Supersonic

Anyway to do this on Windows 7? Another question, would this still work if I just ran Ubuntu from disk?

Thanks, will def.ly give this a try soon...

[DEV GUIDE] Build CM7 from source in its current state. Updated: 2011/05/16-23:52

PLEASE READ THIS BEFORE CONTINUING:
We are changing to a new build system which will result in an updated but VERY different ROM underneath the hood. There is a HIGH POSSIBILITY that building in the current state could BRICK your device, potentially PERMANENTLY. PLEASE DO NOT FLASH unless you are HIGHLY confident you know what you're doing.
For kernel building, see post #2.
For known issues and changelog, see post #3.
Kanged from the CM-Wiki. Yes it's a wiki, yes I could have created an epic page, but we aren't official yet.
Install ADB
Install the Android SDK.
Install the Build Packages
Install using the package manager of your choice:
For 32-bit & 64-bit systems:
Code:
git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool
For 64-bit only systems:
Code:
g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline5-dev gcc-4.3-multilib g++-4.3-multilib
NOTE: On Ubuntu 10.10, and variants, you need to enable the parter repository to install sun-java6-jdk:
Code:
add-apt-repository "deb http://archive.canonical.com/ maverick partner"
Create the Directories
You will need to set up some directories in your build environment.
To create them:
Code:
mkdir -p ~/bin
mkdir -p ~/android/system
Install the Repository
Enter the following to download make executable the "repo" binary:
Code:
curl http://android.git.kernel.org/repo > ~/bin/repo
chmod a+x ~/bin/repo
NOTE: You may need to reboot for these changes to take effect.
Now enter the following to initialize the repository:
Code:
cd ~/android/system/
repo init -u git://github.com/EpicCM/android.git -b teamhacksung-merge
repo sync -j16
Download RomManager and Google Files
NOTE: This only needs to be done when an update to RomManager or GoogleApps is released. If you are up-to-date, you may skip to Building CyanogenMod.
Code:
cd ~/android/system/
./build.sh prepare
Building CyanogenMod
First, check for updates in the source:
Code:
cd ~/android/system/
repo sync
Configure Build & Compile
Now, the environment must be configured to build and the ROM compiled, from code, for the epic.
Code:
cd ~/android/system/
. build/envsetup.sh
./build.sh epic
Build failed? Check post #3 for common problems and solutions.
Install
1. The build system should create a flashable zipfile. Place it on the root of your sdcard.
Optional: Download Google Apps for CyanogenMod 7 and place it on the root of the SD card.
2. Boot into a custom recovery like ClockworkMod Recovery and flash the CM7 update.zip. Then flash google apps if you like.
Please don't flash yet, unless you want an expensive doorstop.

This section of the guide will inform you on how to build a CM7-compatible kernel using our github sources.
Download the Code
Due to the way the new build system works, you'll need the entire CM source to build a proper kernel. (Sorry)
Follow the steps in post #1 to initialize and download our entire CM source repository.
Keeping your code up-to-date:
Code:
cd ~/android/system
repo sync
Toolchain setup
The new build system automatically utilizes the toolchain included in CM7 source.
Prepare to build
The kernel build script requires a few environment vars be set by the CM build system.
Code:
cd ~/android/system/
. build/envsetup.sh
lunch cyanogen_epic-eng
Compile the kernel
Code:
cd ~/android/system/kernel/samsung/2.6.35/
./build.sh epic
cd ~/android/system/releasetools/
./kernel.sh epic
You should now have a flashable zip in out/target/product/epic/
Please don't flash yet, unless you want an expensive doorstop.
This is also incompatible with stock roms, and unless you're amazing, never will be compatible.

KNOWN BUILD-TIME ISSUES
WARNING: These fixes may cause your repo to become out-of-sync from the official repo. Make sure you know how to revert these changes so repo sync doesn't fail.
Error: New build does not boot.
Fix: Working on it
KNOWN RUN-TIME ISSUES
Will update this when it runs.
GUIDE CHANGELOG:
20110516-2352: New build system from teamhacksung.
20110506-1842: Switched to our forks of teamhacksung work.
CODE CHANGELOG:

yes, that's something that we can't easily fix in our own device repo. you could always remove the crespo folder as a temporary fix, but we need to push a patch upstream that fixes crespo makefiles. I will be adding this to known issues shortly.

Yes, it's mentioned in the instructions.
Alternatively, you can use VMWare to do compiling from Windows. That's how I'd set up my old development system. There are tons of free Ubuntu 10.10 vm images.

Updated. Sorry for the mistake in Copy Proprietary Files. That should fix a compile error related to libcamera.

Audio in and out works if you leave it at default values.
If you absolutely want to compile with galaxys audio, it looks like ./extract-files.sh might not be pulling that file? Check ~/android/system/vendor/samsung/epic/proprietary/lib/egl/ for that file.

[Guide]Make your own rom(CM9/EVERVOLV) and kernel from source code | Advanced users

I think many want to know how this stuff is actually done,so....read
Kernel Development
U need Linux or Mac OS .The End
I can confirm the below method works on Ubuntu 11.10,32 bit(or other linux distros/mac u need different packages)
1)Open terminal and download these packages(for both 32/64 bit)
Code:
apt-get install git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
For 64 bit ,install more packages,otherwise leave
Code:
ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
2)Download kernel source code for pico ,which u will compile,from www.htcdev.com (if u want to compile kernel for ics/jb,use lirokoa's source code from www.github.com/lirokoa/htc_pico_kernel )
Extract the archive somewhere safe
3)Download toolchain needed to compile the kernel from www.github.com/sakindia123/android_toolchains
We'll use arm-eabi-4.4.3 for pico

Now let's assume u have correctly set up your machine
extract the sources and everything else u downloaded....then go into the top directory
Code:
cd Kernel
u enter into the root of the kernel directory with this
then type :
Code:
gedit Makefile
The Make file will open.........look out for this and change CROSS_COMPILE= "your toolchain path"
EXAMPLE:
Code:
CROSS_COMPILE ?= /home/sarthak/Downloads/Toolchains/arm-eabi-4.4.3/bin/arm-eabi-
This will open up the Makefile in a gedit,and the changed values will correspond to wherever u placed your toolchain...
Make the kernel config
Code:
make msm7627a_defconfig
NOTE- Do "make htc_pico_defconfig" is making ics/jb kernel
This will make a working kernel config acc. to the source code
Now,make the necessary changes in your source.When you are done,type:
Code:
make -jX
,where X=no.op cpu threads multiplied by 1 or 2.
Sit down and have a smoke!
The resulting kernel will be in Kernel/arch/arm/boot/zImage
Easy,ain't it?
Remember,this guide doesnt teach u how to make particular changes,it just helps u setting up your build environment and compiling from a given source.

Packaging kernel for flashing on target device
- Take a stock boot.img(or any boot.img that works with the rom)
- Downloads boot image tools from -> https://github.com/sakindia123/boot-image-tools and keep them somewhere
- Place boot.img in source_img folder inside the boot.img-tools folder(create if not there)
- Enter the boot tools directory
- Unpack:
Code:
$ mkdir -p unpack
$ tools/unpackbootimg -i source_img/boot.img -o unpack
-Extracting boot.img-ramdisk.gz
Code:
$ mkdir -p boot
$ cd boot
$ gzip -dc ../unpack/boot.img-ramdisk.gz | cpio -i
$ cd ../
Packing a new ramdisk:
Code:
$ tools/mkbootfs boot | gzip > unpack/boot.img-ramdisk-new.gz
Create a new boot.img:
Code:
$ mkdir -p target_img
$ tools/mkbootimg --kernel unpack/boot.img-zImage --ramdisk unpack/boot.img-ramdisk-new.gz -o target_img/boot.img --base `cat unpack/boot.img-base`
Done!
Now take the boot.img from target_img folder and flash via fastboot.Also push the compiled modules or else wifi wont work
Code:
fastboot flash boot boot.img && fastboot reboot
adb push drivers/net/wireless/bcmdhd/bcmdhd.ko /system/lib/modules
adb push drivers/net/kineto_gan.ko /system/lib/modules
NOTE: If u are compiling kernel for stock/sense roms,wifi module will be found in drivers/net/wireless/bcm4330b2/bcm4330.ko
Enjoy !

Compile rom from source
1) Make your own CyanogenMod9 nightly
So cant wait for the developer to release the next build?gettin' itchy?
Compile on your own!
- Packages
For 64-bit systems(For ICS and above,u need 64 bit and above)
Code:
apt-get install git-core gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev:i386 g++-multilib mingw32 openjdk-6-jdk pngcrush schedtool tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386
- Create working directories for the build environment:
mkdir -p ~/bin
mkdir -p ~/android/system
- Get Google's repo tool
Code:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
Reboot
- Sync the Repository
Code:
cd ~/android/system/
repo init -u git://github.com/CyanogenMod/android.git -b ics
repo sync -j16
NOTE- USe -j4 if u have slow net connection!
Wait for a few hours depending upon your net connection,it will download 4-5 GB or more
Then ,after syncing finishes,in the root of the source,open the hidden folder ".repo"
create a file local_manifest.xml and put this xml code to sync relevant repos for compiling cm9 for pico
PHP:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="lirokoa/android_device_htc_pico_ics" path="device/htc/pico" revision="ics" />
<project name="sakindia123/ics-vendor-pico" path="vendor/htc/pico" revision="master" />
</manifest>
then save and do "repo sync " again
- Compile the actual rom
This is fun bit.Make changes to the sourc code if u want to fix bugs or experiment,then,in the root of working directory,type
Code:
. build/envsetup.sh
brunch pico -jX
NOTE- REPLACE X with the no. of cores on your computer,do not enter X
Wait for it to compile(depends on how crap the computer is)
When it finishes compiling,output will be in out/target/product/pico/cm9-UNOFFICIAL-xxxxxxxx.zip
Flash the zip via recovery
Enjoy

Compile Evervolv Nightly
SO u dont want cm9,u want to compile evervolv,eh?
Follow the setups upto "Get Google's repo tool" in cm9 guide,but instead of cm9 source ,sync this
Code:
cd ~/android/system/
repo init -u git://github.com/cm2pico/android.git -b ics
repo sync -j16
After syncing,do this
Code:
nano vendor/ev/vendorsetup.sh
in the text editor that opens up,type
[/CODE]add_lunch_combo ev_pico-eng[/CODE]
Then to compile,
Code:
. build/envsetup.sh
lunch
Select pico in menu and type
Code:
make -jX otapackage
Replace X with no. of cores on pc!
pico up output zip from out/target/product/pico/Evervolv-2.2.0.zip

Nice think I might try this. I'm running osx is there different tools avalible or am I better off installing win or Linux in a vm

time to download
well i have airtel broadband connection(unlimited) on 256 kbps, i get a downloading speed of 30-40 kbps.
so, i wanted to ask you all the size of all the sources/data required to compile a single ROM and time taken to download all those things.

cm9 about 4-5gb, evervolv ics about 6-6.5gb
unlike cm7 where you had to download all supported devices which added additional size to main source (16gb or so) cm9 (by default) and evervolv (from sakindia123 that includes device tree and vendor prop files) both only download the main source only which makes the downloads less in size...........for you it would take a long time to download afew hours (i have 15mbps or 1.5meg a sec so didnt take long) once all setup and synced a single cm9 build takes me just over 1hr and evervolv slightly more, all depends on your hardware ie ram, processor etc.....have fun

really the best way is to fully download in 1 go but in terminal you press Ctrl + z (on Ubuntu) to stop the process and then carry it on later, although it wont sync the whole project until all source is downloaded............

i`ve not used 12.04 for anything, i used 11.10 for cm7 and cm9 but found had to use 10.04.4 (lucid) for evervolv ics (aosp code, not cm modified code) i think jb aosp was compiled on 10.04.4 by android aosp team

[GUIDE] Building Pure Nexus

Introduction
Hello everyone, this is a guide to get you up and running with your own build of Pure Nexus for the Nexus 5X. In this thread, you will learn how to get your computer set up to build and the commands you will need to run. Please read the entire guide and the FAQ. Additionally, this is a developer's thread, there should be no off topic discussion.
Compilation Guide
This is available on my Github, where it may be a little more up to date.
0. Getting started
In this guide, I will go over how to build Pure Nexus on your Linux machine. This particular tutorial will focus on Ubuntu 16.04 as that is what I use (Mint 18 is also good) but this should work with any version of Linux; it does need to be 64-bit however. I will leave the installation of that up to you, Google is a wonderful resource. If you don't have a good computer but still want to build, check out this thread on XDA: http://forum.xda-developers.com/chef-central/android/guide-how-to-build-rom-google-cloud-t3360430
1. Set up your environment
1. Automatically
Code:
sudo apt-get install git-core
git clone https://github.com/akhilnarang/scripts
cd scripts
ls
bash <script-name>
<script-name> should be one of the scripts in the folder for your particular architecture.
2. Manually
1. Install Java 8
Code:
sudo apt-get update
sudo apt-get install openjdk-8-jdk
sudo apt-get install openjdk-8-jre
2. Install other build tools
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip
2. Configure repo and git
If you have any problems with the below commands, try running as root:
Code:
sudo -s
Git is an open source version control system which is incredibly robust for tracking changes across repositories. Repo is Google's tool for working with Git in the context of Android. More reading if you are interested: https://source.android.com/source/developing.html
Run these commands to get repo working (only do this if you did the manual set up method above:
Code:
mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Run these commands to get git working:
Code:
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
3. Download the source
First, before downloading the source, create a folder for the source and move into it.
Code:
mkdir ~/<foldername> (eg. mkdir ~/PN or ~/PureNexus)
cd ~/<foldername>
Then, we need to grab the manifest and sync down the repositories. Here are the commands to do this for Pure Nexus for Nougat (make sure you are in the source folder you made above):
Code:
repo init -u https://github.com/PureNexusProject/manifest.git -b n
repo sync --force-sync
Here is the process generally for other ROMs:
When you go to build a ROM, you must download its source. All, if not most, ROMs will have their source code available on Github. To properly download the source, follow these steps:
Go to your ROM's Github (e.g. http://github.com/PureNexusProject)
Search for a manifest (usually called manifest or android_manifest).
Go into the repo and make sure you are in the right branch (located right under the Commits tab).
Go into the README and search for a repo init command. If one exists, copy and paste it into the terminal and hit enter.
If one does not exist, you can make one with this formula:
Code:
repo init -u <url_of_manifest_repo>.git -b <branch_you_want_to_build>
For example:
Code:
repo init -u http://github.com/PureNexusProject/manifest.git -b n
After the repo has been initialized, run this command to download the source:
Code:
repo sync --force-sync
This process can take a while depending on your internet connection.
4. Build it!
At this point, it'd be a good idea to set up ccache. ccache is a compiler cache, it stores previously compiled files in a directory and pulls from that instead of recompiling if nothing has changed. This speeds up compilation a LOT. If you want to use it, follow the below steps:
Open up your .bashrc file in your home directory using a text editor or nano and append this to the end of it:
Code:
export USE_CCACHE=1
Then type:
Code:
source ~/.bashrc
After that, run one of the below command (replacing the # with how many GBs of ccache you want, 50 is recommended)
Use this one if you used the manual method of set up in section 1:
Code:
prebuilts/misc/linux-x86/ccache/ccache -M #G
Use this one if you used the automatic method of set up in section 1:
Code:
ccache -M #G
After that, it's time to build!
Code:
. build/envsetup.sh
breakfast bullhead
mka bacon
After that, your computer will build the flashable zip file and if you see something that says make completed, you've done it!
Any time that you want to rebuild, type the following commands:
Code:
repo sync --force-sync
. build/envsetup.sh
breakfast bullhead
mka clobber
mka bacon
I also have a script to do this on my Github here
Frequently Asked Questions
1.1 Q: I got an error, what do I do??
1.1 A: Well to start, if it is anything with Ninja, I would go ahead and disable it. You can add this to your .bashrc file:
Code:
export USE_NINJA=false
Then type this
Code:
source ~/.bashrc
. build/envsetup.sh
breakfast bullhead
mka clobber
mka bacon
If it is saying you ran out of memory, follow this post.
If it isn't Ninja related, check out @AzraelsKiss's post here, where he has documented a few common issues. If none of those apply, post here with a detailed list of what you have done and we will do our best to help you.
1.2 Q: Can you guys share your personal builds?
1.2 A: No, personal builds are just that: personal. Beans releases whenever he feels that the release is ready for the masses and if a bunch of personal builds are floating around, that tarnishes the Pure Nexus name. We are more than happy to help get you up and running but we will not be sharing our builds. Thanks for understanding!

this wont work on Windows, right?

If you read at the end of the OP, it says:
"1.2 Q: Can you guys share your personal builds?

Reason being, because if we start compiling these and handing it out like it's no ones business, we're going to run Pure Nexus into the ground and people will start uploading them on AFH and it'll be one big mess. My guess is, this is just a courtesy by the original poster to those of us who can't wait.
My two cents.:laugh::highfive:

i'm on it!!!!! thank you very much!!! download is taking forever ugh

Building it right now! Thanks

I think this would work in Cygwin. I used to compile stuff for the PS3 way back. I'd have a lot of reading to do if I wanted to build this for my phone.

Which gapps to use with this?

Open Gapps micro are working fine.

Out of curiosity, realistically how much disk space would be required to download everything and compile with a 50GB cache? I got everything downloaded and the compile ran but threw some warnings (most of which may have been benign). When the compile terminated with an error, I had about 40MB left on my Linux Mint 18 partition so I assume it ran out of space I started with about 70GB free space
I deleted everything and decided to try again if and when I have a larger partition to play with..... I am currently dual booting on a Windows machine and didn't think to allocate that much space to Mint.
