How to build custom ROM for enchilada(One Plus 6)? - OnePlus 6 Questions & Answers

I am new to AOSP development and want to flash a custom ROM for One Plus 6. I have done the following things:
1. Sync compatible source code with Enchilada:
- Find the build version of One Plus 6: Run adb shell getprop | grep ‘ro.build.id’ This will print OPM1.171019.011.
- Find the similar version at:https://source.android.com/setup/start/build-numbers.html#source-code-tags-and-builds. I found
OPM1.171019.011 android-8.1.0_r1 Oreo Pixel 2 XL, Pixel 2, Pixel XL, Pixel, Pixel C, Nexus 6P, Nexus 5X 2017-12-05
- Initialize repo using repo init -u https://android.googlesource.com/platform/manifest -b android-8.1.0_r1
- Finally, sync the code using repo sync
2. Find the proprietary binaries for the device. I have searched on google and find the below results:
- https://github.com/wuxianlin/android_device_oneplus_enchilada/tree/android-8.1/recovery/root. Here I found the vendor folder but I am not sure that I should copy this vendor folder directly into the aosp source or I need to configure it before copying?
- https://github.com/OnePlusOSS/android. Here, I found that there may exist pull_library.sh in the mobile itself but I am not able to find this file. The One Plus 6 device that I have is rooted and its bootloader is already unlocked. When I have tried to find the file using adb shell ls -lR | find "pull_library.sh" then I got permission errors. Resolved permission errors with `su` but got no result for `ls -lR | find "pull_library.sh"`.
- I have also searched an article https://forums.oneplus.com/threads/...vice-tree-kernel-source-for-oneplus-6.833612/. It refers to a GitHub page for the device tree https://github.com/OnePlusOSS. But due to my insufficient knowledge, I am not able to find the right device tree for my One Plus 6.
- https://forum.xda-developers.com/oneplus-6/development/official-xenonhd-8-1-t3868368 also have device tree and kernel code.
I just need help to understand the process to add binaries in aosp code. If someone can help me to go in right directions then I will be very thankful.

[Resolved] Android Source Repo Download Help (Python Issue?)

NOTE: I Am On Linux Mint 9 32 bit
Okay So I Have Lately been trying TO Get The Latest Android Source Code From Google
Now I Follow The Instructions Down To The Wire (The Ones For Ubuntu, But They Should In Theory Work For Mint 9), And Everything Works Up Until I get To This Part:
Initializing a Repo client
Run "repo init" to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest:
$ repo init -u git://android.git.kernel.org/platform/manifest.git
If you would like to check out a branch other than "master", specify it with -b, like:
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake
When prompted, configure Repo with your real name and email address. If you plan to submit code, use an email address that is associated with a Google account .
A successful initialization will end with a message such as
repo initialized in /mydroid
Your client directory should now contain a.repodirectory where files such as the manifest will be kept.
Click to expand...
Click to collapse
And When I Try To Run That Line Through The Terminal I Get This Error:
Code:
Traceback (most recent call last):
File "/bin/repo", line 91, in ?
import readline
ImportError: No module named readline
Now I Know What The Problem is, It Is Looking For The readline.so in the the lib folder, Yet Even Though It Is There It Still Wont Work.
Now I Have Tried All 2.x.x Versions Of Python (2.4.6, 2.5.5, & 2.6.4) and None Of Them Work.
Also With Each Version I Run:
Code:
$ ./configure --enable-readline
And Still the Same Error.
i Have Been working On this For About 3 Hours Now And Still Now Luck.
I Tried A Google Search But Every Topic Get Close To Helping Someone Get It Then Stops.
Please Help Me Out Here ?
Okay So I Found The Solution.
repo runs STRICTLY off of 2.4.x and for some reason when I installed Python 2.4.6 readline.so was never put into:
Code:
/usr/local/lib/python2.4/lib-dynload/
So I copied the readline.so from my Python 2.6.4 folder (File Download Below)
and put it into:
Code:
/usr/local/lib/python2.4/lib-dynload/
Then I ran repo again and it worked fine.
Although it withh give you an API mismatch warning, but so far it has worked fine
i had that problem so i edited repo itself and deleted line 91

[CM 7.2 Alpha 8.3] help for get source code.

Hi all,
First of all, where I can find a good tuto for starting dev ?
I want help for porting CM 7.2 so I find this in the thread:
1. Download source codes
- Get cyanogenmod source in a directory (eg: /cm7/)
- put device config to device/samsung/apollo
- put vendor files to vendor/samsung/apollo
- put cyanogen vendor files to vendor/cyanogen
Click to expand...
Click to collapse
I understand how too get "device config", "vendor files" and "cyanogen vendor files" but not "cyanogenmod source".
I think, I will get it with this command:
repo init -u git://github.com/CyanogenMod/android.git -b gingerbread
Thanks all.

yes, then
Code:
# repo sync -j4
and you will get the cyanogenmod source (cm7).
Thanks for the help for get CM7 source code.
For cyanogen vendor files, the folder already exist. What i need to do?
1 - merge the too folder (remplace existing file with yours)
2 - delete all files in the folder and put just your files in it

I have test the two : The solution is the first.
For doing it, I make a clone of your git repository in a temp directory. After that I copy the result in vendor/cyanogen.
I don't find a git comand to do it, does it exist ?
I tried too use eclipse indigo by following android source documentation.
When I tired too create the java project, there isn't "Create project from existing source" option. So, I search on google but I find any thing for CM and android source code.
What must I do?

[GUIDE][Lollipop]How to fix constant Google Play Services FC

Most of you would have experienced or heard of the constant 'Google Play Services has stopped' messages problem, and here I present a fix! Just follow the guide below to compile your own fixed libjavacore.so which you just copy to /system/lib(overwriting the existing one) and you should see the problem is solved The fix from Google: libjavacore.so fix. EDIT: Unfortunately the fix causes build errors on newer Android source code, so a modified version of the commit is used now: thanks @zephiK
NOTE: If you are using a PURE AOSP ROM, and your ROM build date is later than Mon Mar 23 2015, then you likely DO NOT need this fix
NOTE: This guide assumes that you already have a build environment setup for your device in question(and that you already finished a repo sync), and that you have basic knowledge about how to use a Linux Terminal. There are many guides on the internet on this topic so I'll leave it out.
Steps: First open a new Terminal session on your Linux/Cygwin machine
RECOMMENDED BUT OPTIONAL: Do a 'repo sync'(you can just do it on the libcore repo) and a 'make clean'
Code:
repo sync -j4
Code:
make clean
1. Go to the 'libcore' directory in the root of your android source tree
Code:
cd libcore
2. Add a new remote with whatever name you want(in this guide I will call the new remote fix)
Code:
git remote add [COLOR="red"]fix[/COLOR] https://android.googlesource.com/platform/libcore
Code:
git remote add [COLOR="red"]fix[/COLOR] https://github.com/zephiK/android_libcore.git
3. Now do a git fetch on 'fix'(or whatever name you called the new remote)
Code:
git fetch [COLOR="red"]fix[/COLOR]
4. Now time for a cherry-pick!
Code:
git cherry-pick 08d97aee56db51f718544562f5b74671be34dfaf
Code:
git cherry-pick 4fd69cb3de4e52b5b6d78ac61237f914853de151
OPTIONAL: Remove the new remote(Replace fix with whatever name you called it)
Code:
git remote remove [COLOR="red"]fix[/COLOR]
5. Now the fix has been imported into libcore, which will be compiled into a fixed libjavacore.so!
Code:
cd ..
source build/envsetup.sh
make -j4 libjavacore
6. Just wait for a while(probably about 30 mins on an average computer), and then goto your out directory. Proceed to 'target/product/<device name>/system/lib', and you should find a newly compiled libjavacore.so
Code:
cd $OUT/target/product/<device name/system/lib>
7. Now just upload it to your device, and copy it to /system/lib with 0644 permissions(in other words, -rw-r-r). Optional: backup the original /system/lib/libjavacore.so in case something goes wrong or this fix doesn't work
Code:
chmod 0644 /system/lib/libjavacore.so
You are now done! Feel free to share the lib to help others solve their problems, and enjoy lollipop

Guide: Compile /system/bin binaries for your device from AOSP source code

Now tested up to downloading AOSP and make toolbox you should be all set
Please give thanks to this thread: https://forum.xda-developers.com/newreply.php?do=newreply&p=43622764
Warning: I hacked my way through this stuff a few weeks ago I am not an expert!
How to compile Android Open Source Code modules​
I don't compile C code on Windows machines I have no idea about that.
Notice
This guide is a quick and dirty how to make a module. It will not cover finalizing setting up the source codes for your device. It is only my goal to enable you to compile binaries such as grep, toolbox, dumpstate, dalvikvm, jack and etc.
===>] Setup Ubuntu 64bit [<===​Unplug that Windows drive, plug in a fresh hard drive and install Ubuntu latest/greatest. Ignore the recommendation to downgrade gnu make!, for now.
Open a terminal and issue these commands (warning ppa repository for OpenJDK 7 is said to have a security issue?, isn't being updated?.. whatevs it works)
Code:
sudo apt-get update
sudo apt-get upgrade
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get install openjdk-7-jdk
sudo apt-get install openjdk-8-jdk
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386
sudo apt-get install git ccache automake lzop bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 g++-multilib python-networkx libxml2-utils bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev squashfs-tools pngcrush schedtool dpkg-dev liblz4-tool make optipng
(choose Java 1.7 in the following way)
Code:
sudo update-alternatives --config java
(let me know if I missed anything please)
"Tried the Android SDK only it is missing too many things we need as a developer"
===>] Setup Android Studio SDK & NDK [<===​Installation Paths:
*** I install to /home/username/Android and /home/username/Android/Sdk and /home/username/Android/Sdk/ndk-bundle ***
NOTE: from here forward username will == droidvoider
Note: Android Studio IDE isn't necessary only the SDK & NDK are needed to compile AOSP.
Install Android Studio Proper: (don't worry about setting up paths we will cover that, just install it)
https://developer.android.com/studio/install.html
or
SDK Only:
Typically we install these things manually by creating the directory then just unzipping the files there.
https://developer.android.com/studio/index.html#linux-bundle (scroll down for sdk only)
Code:
mkdir /home/droidvoider/Android
mkdir /home/droidvoider/Android/Sdk
(then unzip the sdk zip to that directory. I recommend the file explorer copy/paste right click uncompress and done.)
https://dl.google.com/android/repository/tools_r25.2.3-linux.zip
Install NDK through the SDK Manger:
(from terminal 'studio.sh' and then configure, and then sdk manger --- if this is hard to figure out tell me I will elaborate)
or
Manually Install Native Development Kit -- 'c programming support'
Download the Native Development Kit from Google: https://developer.android.com/ndk/downloads/index.html
Code:
mkdir /home/droidvoider/Android/Sdk/ndk-bundle
Then just unzip the ndk files into the directory we created above.
===>] Setup your toolchain [<===​** This example is arm64-v8a aarch64 **
1. Navigate to /home/droidvoider/Android/Sdk/ndk-bundle/build/tools and then open a terminal "right click open area"
2. mkdir /home/droidvoider/toolchains
3. ./make_standalone_toolchain.py --arch arm64 --api 23 --stl=libc++ --install-dir /home/mm/toolchains/aarch64-linux-android-4.9
4. cd /home/droidvoider
5. gedit .bashrc and morph this in at the bottom.. (AND edit or replace the existing PATH variable)
DON'T just PASTE IN *my* $PATH export!! I included my entire path statements to show you.
Code:
export PATH=$PATH:/usr/local/android-studio/bin:/home/droidvoider/Android/Sdk/platform-tools:/home/droidvoider/Android/Sdk/ndk-bundle:/home/droidvoider/Android/Sdk/tools
I feel this is human readable, for example change Android_Build_Out to be on your desktop instead if you want.
Code:
export PATH=$PATH:/home/droidvoider/toolchains/aarch64-linux-android-4.9
export NDK=/home/droidvoider/Android/Sdk/ndk-bundle
export SYSROOT=$NDK/platforms/android-23/arch-arm64
export TARGET=aarch64-linux-android
export HOST=$TARGET
export BUILD=x86_64-linux
export ANDROID_NDK_BIN=/home/droidvoider/toolchains/aarch64-linux-android-4.9/bin
export CC=$ANDROID_NDK_BIN/aarch64-linux-android-gcc-4.9
export CPP=$ANDROID_NDK_BIN/aarch64-linux-android-g++
export AR=$ANDROID_NDK_BIN/aarch64-linux-android-ar
export OUT_DIR_COMMON_BASE=/home/droidvoider/Android_Build_Out
Note: You might want to setup an alternate toolchain also but this is all of the puzzle pieces.
===>] Google's version of this How To -- Just for reference [<===​https://source.android.com/source/requirements.html

(don't type repo init or repo sync --- I will be taking back over from there on the next page)
Added Repair Notes -- Not part of the install!
Have you accidentally installed or removed something you shouldn't have? (welcome to development, here try this before reinstall)

Selecting the correct AOSP branch and downloading it.
Tested up to downloading AOSP and make toolbox -- you should be all set
===>] Match your build number to it's AOSP sources [<===​preface: You can get this from your device if you're on the same build id as your the available source code from your vendor for your device. Otherwise you need to open the AP file from the firmware that matches those available sources to extract the system.img, to extract build.prop. I explain how to open a system.img file below under retrieving your hardware drivers. build.prop is in the main directory of system.img
(Many times the build number is the same. For me I believe all of MM builds are using this number.)
Assumes sources match current device, worked out true in my case
1. Plug in your device and get it connected. (DEVELOPER OPTIONS|USB DEBUGGING) and select allow on device
2. Retrieve the build number that matches the available sources for your device.
From your ubuntu terminal retrieve the build id using this command:
Code:
adb shell getprop | grep 'ro.build.id'
Yields something similar to this: [ro.build.id]: [MMB29K]
3. Match it up to the Nexus build numbers (This info is for AT&T Note 5 Marshmallow MMB29K, get your specific build number!)
https://source.android.com/source/build-numbers.html#source-code-tags-and-builds
MMB29K android-6.0.1_r1 Marshmallow Nexus 5, Nexus 5X, Nexus 6, Nexus 7 (flo/deb), Nexus 9 (volantis/volantisg)
===>] Bring down a specific AOSP source branch [<===​
4. Make a directory for the source code.
Code:
mkdir /home/droidvoider/Desktop/AOSP_Android_6.01_r1
5.
Code:
cd /home/droidvoider/Desktop/AOSP_Android_6.01_r1
6. Bring down the sources, this one is approximately 13 gigabytes
Code:
repo init --depth=1 -u https://android.googlesource.com/platform/manifest -b android-6.0.1_r1
repo sync
===>] I'm not sure the rest of this is needed [<===​For compiling toolbox the remainder wasn't needed.. But I have a large list of things to do so I can't test each item. If you can't compile a specific module continue reading.
===>] Merge Vendor sources & AOSP sources [<===​
7. Download the available sources for your device. In this example I downloaded PE6 Marshmallow sources for AT&T Note 5:
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=SM-N920A
8. Read the readme file from the sources platform zip to understand how to merge them into the AOSP sources. For the 2 Samsungs I've worked with the idea is to replace any directory that already exists. But if there is just one file such as core.mk only replace the one file. Then edit the .mk files as described in your readme. (and/or take info from cyanogen/lineagos) -- <I can help more, ask>
note: you probably don't need to take the configs from LineageOS and put them into your .mk files. However, if you do need to get more configs then you should get a big fat message when you type make 'modulename'. At first only edit .mk files as described by vendor device source readme file.
===>] Merge in Hardware drivers and etc [<===​possibly unnecessary depends what you're doing
9. Obtain a copy of the firmware for your device that matches the version of the source code you are able to download from your vendor.
for me that was Build Number: MMB29K.N920AUCU2BPE6 but your mileage will almost certainly vary!
10. Download https://github.com/anestisb/android-simg2img
11. Unzip it right in your download folder, open the folder and then 'open in terminal'
12. Make it and then move it a directory in your path. Warning: My command puts in in the Ubuntu default /bin folder.
Code:
make
sudo mv append2simg img2simg simg2img simg2simg simg_dump.py /bin
13. Uncompress the AP file from the matching firmware and extract the system.img into it's own directory
then select that folder, right click, open in terminal
Code:
simg2img system.img sys.raw
mkdir sys
sudo mount -t ext4 -o loop sys.raw sys/
14. A drive mounted, look on your task bar it should've wiggled too. Copy the etc and vendor folders into the main folder of the sources we are merging
===>] Listing and building modules [<===​Navigate to the folder where you download the sources "/home/droidvoider/Desktop/AOSP_Android_6.01_r1" and open in terminal.
Code:
make modules -- list the available modules
make <module name> -- builds a specific module
example: make dumpstate
description: Will build everything needed for dumpstate and place it in the folder we specified in our export (above step). The final build line will read install and detail the final output folder
Example successful output:
[CODE]
Install: /home/droidvoider/Android_Build_Out/Android_6.01_r1/target/product/generic/system/bin/dumpstate
===>] Android Build System, basic intro [<===​Notice: I built this how to to answer the same question from 3 people regarding working with toolbox and the dirtycow exploit. So I decided to give a direct example of using toolbox.c from farm-root
#ifdef
Our makefile is Android.mk and that's where we link things together. If you look at the Android.mk file for farm-root you will notice bridge.c is used 3 different times called different 'module' names. bridge_pull, bridge_push, bridge_pull_boot. Each of these will be binaries of those names.
Inside bridge.c you will see #ifdef FARM_PULL and then you will see #else and further you will see #endif which you may have noticed matches inside the Android.mk file for the bridge modules -DFARM_PULL -DFARM_BOOT <== Notice the double define on bridge_pull_boot
toolbox.c
toolbox.c is going to be the same way. You will need to copy shared.h and shared.c into the directory where toolbox.c resides. Then edit the Android.mk, in our example:
1. Navigate to this directory and open: system/core/toolbox/Android.mk
2. CTRL + F and search for "LOCAL_MODULE := toolbox"
3. Add: LOCAL_CFLAGS += -DFARM_PULL -DFARM_BOOT (in this example add one, both or even new ones you created)
4. Navigate to the main directory of the sources, you should see a Makefile and a build_64bit.sh
5. from terminal: make toolbox
Note: I think from here you can Google it out in a few minutes if that is not the case please let me know.
Working with C cross platform​Ubuntu is Linux based just like Android and this makes testing blocks of code extremely easy. You of course can't use Android headers and in some rare cases you can't test the code on Ubuntu at all but in most cases you can. When I want to design something for Android I open gedit and save it as a .c file. Then I compile it using gcc -o mycode mycode.c There's plenty of examples on using gcc with linux but just understand you can do it all. Then before too much work test it on Android. (helpful commands at end of post)
My advice really is to build out your small blocks of code on your linux box but then paste them into your Android program folder, edit your Android.mk, add it to your Makefile including your 'push' section so that you can simply type make push to test it.
I am in fact trying to encourage you to learn C and not so much trying to encourage you to hack things. But I know that interest/passion is what teaches, not my words and not someone else's curriculum. So in that spirit I will do my best to give examples to help you with 'whatever' it is you are passionate about. Let me know what's missing.
Don't forget to compile for Android first
Before you can test your code you will have compiled it using the cross compiler for Android. ndk-build, or the correct gcc cross compiler. (Personally I put the .c file into a directory with Android.mk and a Makefile then just type make to build it to Android)
see examples section I will add a couple examples.
Android Developer Bridge -- a developers tool
adb is included with the Android SDK along with some other tools. Some of those tools are fastboot for unlocking bootloaders and another way of flashing. There is monitor which is a cool tool for remotely viewing processes, logcat, memory dumps and etc.
But pointedly what we will use the most is simply adb.
Using adb to test your code on locked down Android systems
Shell has fairly high privileges, you may not be aware but you can execute binaries and bash scripts. We use /data/local/tmp/ for these things. You can create a directory, add or remove files, execute your binaries and even execute shell scripts using sh script.sh
ndk-build places the binary in libs/(arch type) .. For a quick test you can just open a terminal in that directory then:
Code:
adb push mybinary /data/local/tmp/
adb shell
cd data/local/tmp
chmod 777 mybinary
./mybinary
Added:
Examples of basic make files for Android.
happy coding
If you get an error​Please reissue the command but pipe the output to a file.
make toolbox > /home/droidvoider/Desktop/build_toolbox-output.txt
zip that up with your source code, including your customized header files and attach it to this thread.
puzzles are fun but I like all the pieces

it's no problem this stuff isn't easy to just figure out on your own. remember to substitute droidvoider for your ubuntu user name
In this example my sources are on my desktop in a folder named Android_6.01_r1
Sources for toolbox for example:
/home/droidvoider/Desktop/Android_6.01_r1/system/core/toolbox/<sources will be here including Android.mk>
Script for modules, including toolbox
/home/droidvoider/Desktop/Android_6.01_r1/Makefile <--- this is our modules script, if you will
<open a terminal in the above folder then use that Makefile like so>
make toolbox <---- this will compile only what is needed to compile the module 'toolbox' (this takes a minute)
Out export folder we decided in ./home/droidvoider/bashrc
/home/droidvoider/Android_Build_Out/Android_6.01_r1/target/product/generic/system/bin
Anybody, please compile grep utility for arm and x86... Minimum Platform Version Android 4.0.3, API Level - 15
Thanks
Great & useful .

[GUIDE] Build Rom from Source For Tissot

What is ?
Android is the open-source operating system used for smartphones. Full Freedom for people using it
What is Source Code?
Android is an open-source software stack created for a wide array of devices with different form factors. The primary purposes of are to create an open software platform available for carriers, OEMs, and to make their innovative ideas a reality and to introduce a successful, real-world product that improves the mobile experience for users.The result is a full, production-quality consumer product with source code open for customization and porting.
So basically Allows to customize the things you like and make new things without any Restrictions. Cool isn’t it?
What is ROM ?
The ROM is the operating system. This is the User interface (Sense UI in HTC phones) and the file system for maintaining contacts etc. It is composed of a Linux kernel and various add-ons to achieve specific functionality.
What does a Rom Contain ?
Basically a Rom Contains following main things :
· Kernel
· Bootloader
· Recovery
· Radio
· Framework
· Apps
· core
· -runtime,Etc
Some Basics About Above Terms
Kernel :
A kernel is critical component of the and all operating systems. It can be seen as a sort of bridge between the applications and the actual hardware of a device. devices use the Linux kernel, but it's not the exact same kernel other Linux-based operating systems use. There's a lot of specific code built in, and Google's kernel maintainers have their work cut out for them. OEMs have to contribute as well, because they need to develop hardware drivers for the parts they're using for the kernel version they're using. This is why it takes a while for independent and hackers to port new versions to older devices and get everything working. Drivers written to work with the Gingerbread kernel on a phone won't necessarily work with the Ice Cream Sandwich kernel. And that's important, because one of the kernel's main functions is to control the hardware. It's a whole lot of source code, with more options while building it than you can imagine, but in the end it's just the intermediary between the hardware and the software. So basically if any instruction is given to mobile it first gives the command to kernel for the particular task execution.
Bootloader :
The bootloader is code that is executed before any Operating System starts to run. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. Think of the bootloader as a security checkpoint for all those partitions. Because if you’re able to swap out what’s on those partitions, you’re able to break things if you don’t know what you’re doing. So basically it commands the kernel of your device to Boot the Device properly without any issues. So careful with bootloader since it can mess things very badly.
Recovery :
Recovery is defined in simple terms as a source of backup. Whenever your phone firmware is corrupted, the recovery does the job in helping you to restore or repair your faulty or buggy firmware into working condition. It is also used for flashing the Rom’s , kernel and many more things.
Radio
The lowest part of software layer is the radio: this is the very first thing that runs, just before the bootloader. It control all wireless communication like GSM Antenna, GPS etc.
What you’ll need
A relatively recent 64-bit computer (Linux, OS X, or Windows)(Virtual Machine will work as well) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
A decent internet connection & reliable electricity
Some familiarity with basic operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.
Install the SDK
If you haven’t previously installed adb and fastboot, you can download them from Google. Extract it running:
Code:
unzip platform-tools-latest-linux.zip -d ~
Now you have to add adb and fastboot to your PATH. Open ~/.profile and add the following:
Code:
# add SDK platform tools to path
if [ -d "$HOME/platform-tools" ] ; then
PATH="$HOME/platform-tools:$PATH"
fi
Then, run source ~/.profile to update yur environment.
Install the build packages
Several packages are needed to build LineageOS. You can install these using your distribution’s package manager.
To build LineageOS, you’ll need:
bc bison build-essential curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev
For Ubuntu versions older than 16.04 (xenial), substitute:
libwxgtk3.0-dev → libwxgtk2.8-dev
Java
Different versions of LineageOS require different JDK (Java Development Kit) versions.
LineageOS 14.1: OpenJDK 1.8 (install openjdk-8-jdk)
LineageOS 11.0-13.0: OpenJDK 1.7 (install openjdk-7-jdk)*
https://askubuntu.com/questions/761127/how-do-i-install-openjdk-7-on-ubuntu-16-04-or-higher
Create the directories
You’ll need to set up some directories in your build environment.
To create them:
Code:
mkdir -p ~/bin
mkdir -p ~//lineage
Install the repo command
Enter the following to download the repo binary and make it executable (runnable):
Code:
curl [url]https://storage.googleapis.com/git-repo-downloads/repo[/url] > ~/bin/repo
chmod a+x ~/bin/repo
Put the ~/bin directory in your path of execution
In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing):
Code:
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
Then, run source ~/.profile to update your environment.
Initialize the LineageOS source repository
Code:
cd ~//lineage
repo init -u [url]https://github.com/LineageOS/.git[/url] -b lineage-15.1
Download the source code
Code:
repo sync -c -f --force-sync --no-clone-bundle --no-tags --optimized-fetch --prune
Prepare the device-specific code
Code:
git clone [url]https://github.com/TheScarastic/android_device_xiaomi_msm8953-common[/url] -b lineage-15.1 device/xiaomi/msm8953
git clone [url]https://github.com/TheScarastic/android_device_xiaomi_tissot[/url] -b lineage-15.1 device/xiaomi/tissot
git clone [url]https://github.com/TheScarastic/proprietary_vendor_xiaomi[/url] -b lineage-15.1 vendor/xiaomi
git clone [url]https://github.com/Tissot-Development/android_kernel_xiaomi_tissot[/url] -b 8.1 kernel/xiaomi/msm8953
Turn on caching to speed up build
Code:
export CCACHE_DIR=./.ccache
ccache -C
export USE_CCACHE=1
export CCACHE_COMPRESS=1
prebuilts/misc/linux-x86/ccache/ccache -M 50G
Configure jack
Jack is the new Java compiler used when building LineageOS 14.1. It is known to run out of memory - a simple fix is to run this command:
Code:
export _JACK_VM_ARGS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4G"
Make Clean Build
Code:
make clean
Initialize the build command
Code:
source build/envsetup.sh
Start Build
Code:
croot
brunch tissot

Around 20-25GB I think
Followed the above steps to the letter but I get an error right at the beginning:
Code:

Hello,
Don't use that kernel, as actually don't work properly in Xiaomi Mi A1. This error is caused because the file "lineage_tissot_defconfig" it's not named like that, exactly it's name is "tissot_defconfig", for your first build with lineage I recommend you to use the following sources, because are adapt for Lineage. Don't forget to use superuser privileges to compile, it avoids a lot of possible errors with normal user.

Vendor
Kernel
Give thanks to user @ghpranav for sources :good:

Between 3 to 5h in modern pc, probably you will need between 7 to 10h in a laptop, depends on Nº of Cores and RAM, anyway, good luck in your first compilation :good:

Hello and thanks for the guide.
I am trying to build Dirty Unicorns 7.1.2 for tissot. I have downloaded kernel, vendor and device and repo synced DU n7x branch. I have also downloaded device_qcom_sepolicy and changed some files in device/xiaomi/tissot folder in order for the build to start normally. After 1.30 minutes of building i get this error
Code:
ninja: error: '/home/manoskav/du-tissot/out/target/product/tissot/obj/STATIC_LIBRARIES/bootctrl.msm8953_intermediates/export_includes', needed by '/home/manoskav/du-tissot/out/target/product/tissot/obj/EXECUTABLES/update_engine_sideload_intermediates/import_includes', missing and no known rule to make it
make: *** [build/core/ninja.mk:167: ninja_wrapper] Error 1
Maybe should i try n7x-caf branch or n7x is ok for tissot? Can anyone help me with the building process?
Thanks in advance.
