Compile Android system with LineageOS

Cyanogen is a company that customizes Android ROM, its product CyanogenMod( Often referred to as "CM") is an open code system based on the Android mobile device platform. In December 2016, Cyanogen suddenly announced that it would stop development and close the project infrastructure. LineageOS was officially launched on December 24, 2016 to re-enact CyanogenMod, and its source code is stored in GitHub。

Development Environment (Host)

The operating system uses Ubuntu 18.04

Install the development kit

$ sudo apt-get update
$ sudo apt-get install bc bison build-essential ccache curl flex g++-multilib gcc-multilib git gnupg gperf 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 python-mako imagemagick openjdk-8-jdk gcc-arm-linux-gnueabihf

OpenJDK version 1.8.0_232

# installation
$ sudo apt-get update 
$ sudo apt-get install openjdk-8-jdk
# If your computer has installed many versions of JDK, specify which version of JDK to use here
$ sudo update-alternatives --config java

It is recommended to use SSD hard disk (download and compile will wait until death) -Lineage 15.1 code machine plus compile output file about 70G -Lineage 16.0 code machine plus compile output file about 140G

Operating Instructions

How to download LineageOS code

branch: lineage-15.1, Device name: rpi3
branch: lineage-16.0, Device name: rpi4

#Automated download script
$ wget https://raw.githubusercontent.com/02047788a/build-lineageOS-rpi3/master/scripts/sync-lineageos-code.sh -O sync-lineageos-code.sh
# Execute script input prompt
# Please entry lineageOS checkout folder : (Download catalog)
# Please entry checkout lineageOS branch : (Designated branch)
# Please entry build device name(ex:,rpi3,rpi4) : (Compile module)

All input variables exist~/.profile inside ($LINEAGE_SRC, $LINEAGE_BRANCH, $DEVICE_NAME)

How to compile LineageOS code

# Download the script to the code directory
$ wget https://raw.githubusercontent.com/02047788a/build-lineageOS-rpi3/master/scripts/build-lineageos-code.sh -O build-lineageos-code.sh
$ sudo ./build-lineageos-code.sh #Compile all images kernel ramdisk systemimage vendorimage

Installable after compilation image path: $LINEAGE_SRC/out/target/product/rpi4/lineage-16.0-20200201-rpi4.img*

Burn image to SD card
```
$ sudo dd if=lineage-16.0-20200201-rpi4.img of=/dev/sdX status=progress bs=4M
```
/dev/sdX Is the path of your SD card，Pay attention to change!!!
