# Build LineageOS

|
|
|
|
## Preparing environment
|
|
I'll be using a container to keep my main system clean
|
|
|
|
Adapted from [How to build LineageOS inside a container](https://dzx.fr/blog/how-to-build-lineageos-inside-a-container/)
|
|
|
|
```
|
|
$ podman run -itd --name lineageos-build \
|
|
-v /mnt/storage/lineageos-build:/var/lineageos-build \
|
|
-v /home/marc/lineageos-cache:/var/lineageos-cache \
|
|
docker.io/ubuntu:jammy-20220531
|
|
```
|
|
|
|
Enter the newly created container
|
|
`$ podman exec -it lineageos-build bash`
|
|
|
|
Install the necessary packages
|
|
`# apt update`
|
|
`# apt install bc bison build-essential ccache curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5 libncurses5-dev libsdl1.2-dev libssl-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev python-is-python3 vim`
|
|
|
|
Add an unpriviledged user for building
|
|
Make sure it can access the lineageos folders mounted
|
|
`# adduser --disabled-password (user)`
|
|
`# chown (user):(user) -R /var/lineageos-*`
|
|
`# su exu`
|
|
|
|
Set cache and export to bashrc
|
|
Create the file `~/.config/ccache/ccache.conf`
|
|
```
|
|
max_size = 30G
|
|
cache_dir = /var/lineageos-cache
|
|
```
|
|
|
|
`$ echo 'export USE_CCACHE=1' >> ~/.bashrc`
|
|
|
|
### Install repo tool
|
|
```
|
|
$ mkdir -p ~/.local/bin/
|
|
$ source ~/.profile
|
|
```
|
|
|
|
```
|
|
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.local/bin/repo
|
|
$ chmod a+x ~/.local/bin/repo
|
|
```
|
|
|
|
```
|
|
$ git config --global user.email mrc@frm01.net
|
|
$ git config --global user.name RealStickman
|
|
```
|
|
|
|
### Get source lineage code
|
|
```
|
|
$ mkdir -p /var/lineageos-build/lineage/
|
|
$ cd /var/lineageos-build/lineage/
|
|
```
|
|
|
|
Initialize the repo
|
|
`$ repo init -u https://github.com/LineageOS/android.git -b lineage-18.1`
|
|
|
|
Sync repo content
|
|
This can take a long time
|
|
`$ repo sync --force-sync`
|
|
|
|
Repo fetches the latest version automatically, so we can use a symlink
|
|
`$ ln -sf /var/lineageos-build/lineage/.repo/repo/repo ~/.local/bin/repo`
|
|
|
|
### Download device source files
|
|
Activate the build environment
|
|
`$ . ./build/envsetup.sh`
|
|
|
|
Finally, download device specific source files
|
|
`$ breakfast DEVICE_CODENAME`
|
|
Device names:
|
|
```
|
|
oneplus3
|
|
```
|
|
|
|
If `breakfast` fails, you need to extract the proprietary blobs
|
|
[Extract blobs from the device](https://wiki.lineageos.org/devices/oneplus3/build#extract-proprietary-blobs) or [Extract blobs from LineageOS zip files](https://wiki.lineageos.org/extracting_blobs_from_zips)
|
|
|
|
## Start build
|
|
Full build
|
|
`$ brunch DEVICE_CODENAME`
|
|
|
|
Kernel only
|
|
`$ mka bootimage`
|
|
|
