Introduction | Security Warning | Devices

Sophisticated chroot/build/flash tool to develop and install postmarketOS.

Package build scripts live in the pmaports repository now.

Requirements

Usage Examples

Please refer to the postmarketOS wiki for in-depth coverage of topics such as porting to a new device or installation. The help output (pmbootstrap -h) has detailed usage instructions for every command. Read on for some generic examples of what can be done with pmbootstrap.

Installing pmbootstrap

https://wiki.postmarketos.org/wiki/Installing_pmbootstrap

Basics

Initial setup:

$ pmbootstrap init

Run this in a second window to see all shell commands that get executed:

$ pmbootstrap log

Quick health check and config overview:

$ pmbootstrap status

Packages

Build aports/main/hello-world:

$ pmbootstrap build hello-world

Cross-compile to armhf:

$ pmbootstrap build --arch=armhf hello-world

Build with source code from local folder:

$ pmbootstrap build linux-postmarketos-mainline --src=~/code/linux

Update checksums:

$ pmbootstrap checksum hello-world

Generate a template for a new package:

$ pmbootstrap newapkbuild "https://gitlab.com/postmarketOS/osk-sdl/-/archive/0.52/osk-sdl-0.52.tar.bz2"

Chroots

Enter the armhf building chroot:

$ pmbootstrap chroot -b armhf

Run a command inside a chroot:

$ pmbootstrap chroot -- echo test

Safely delete all chroots:

$ pmbootstrap zap

Device Porting Assistance

Analyze Android boot.img files (also works with recovery OS images like TWRP):

$ pmbootstrap bootimg_analyze ~/Downloads/twrp-3.2.1-0-fp2.img

Check kernel configs:

$ pmbootstrap kconfig check

Edit a kernel config:

$ pmbootstrap kconfig edit --arch=armhf postmarketos-mainline

Root File System

Build the rootfs:

$ pmbootstrap install

Build the rootfs with full disk encryption:

$ pmbootstrap install --fde

Update existing installation on SD card:

$ pmbootstrap install --sdcard=/dev/mmcblk0 --rsync

Run the image in QEMU:

$ pmbootstrap qemu --image-size=1G

Flash to the device:

$ pmbootstrap flasher flash_kernel
$ pmbootstrap flasher flash_rootfs --partition=userdata

Export the rootfs, kernel, initramfs, boot.img etc.:

$ pmbootstrap export

Extract the initramfs

$ pmbootstrap initfs extract

Build and flash Android recovery zip:

$ pmbootstrap install --android-recovery-zip
$ pmbootstrap flasher --method=adb sideload

Repository Maintenance

List pmaports that don't have a binary package:

$ pmbootstrap repo_missing --arch=armhf --overview

Increase the pkgrel for each aport where the binary package has outdated dependencies (e.g. after soname bumps):

$ pmbootstrap pkgrel_bump --auto

Generate cross-compiler aports based on the latest version from Alpine's aports:

$ pmbootstrap aportgen binutils-armhf gcc-armhf

Manually rebuild package index:

$ pmbootstrap index

Delete local binary packages without existing aport of same version:

$ pmbootstrap zap -m

Debugging

Use -v on any action to get verbose logging:

$ pmbootstrap -v build hello-world

Parse a single deviceinfo and return it as JSON:

$ pmbootstrap deviceinfo_parse pine64-pinephone

Parse a single APKBUILD and return it as JSON:

$ pmbootstrap apkbuild_parse hello-world

Parse a package from an APKINDEX and return it as JSON:

$ pmbootstrap apkindex_parse $WORK/cache_apk_x86_64/APKINDEX.8b865e19.tar.gz hello-world

ccache statistics:

$ pmbootstrap stats --arch=armhf

distccd log:

$ pmbootstrap log_distccd

Development

Requirements for running tests

You also need to install the following python packages (pip can be useful if you distribution hasn't got them packaged):

  • pytest
  • pytest-cov (only needed for test/testcases_fast.sh, which is what CI runs)
  • flake8

On Alpine Linux it can be done with:

$ sudo apk add grep shellcheck py3-pytest py3-pytest-cov py3-flake8

Running linters

The easiest way is to run the same script CI runs:

$ ./test/static_code_analysis.sh

Running tests

You can now run pytest -vv inside the pmbootstrap folder to run all available tests.

CI runs slightly reduces set of tests (it skips tests that require running qemu) by this:

$ ./test/testcases_fast.sh

This is the easiest way to do the same as CI.

Alternatively you can run a single test if you wish:

$ pytest -vv ./test/test_keys.py
