OpenBh buildserver requirements:

Ubuntu 24.04 LTS (GNU/Linux 6.8.0-39-generic x86_64)

minimum hardware requirement for image build (building feeds may require more):

RAM: 16GB SWAP: 16GB (if building feeds then RAM+SWAP should be larger)> CPU: Multi core\thread Model HDD: for Single Build 250GB Free, for Multibuild 500GB or more

OpenBh python3 is built using oe-alliance build-environment and several git repositories:

https://github.com/oe-alliance/oe-alliance-core/tree/5.4

https://github.com/BlackHole/enigma2

Building Instructions

1 - Install packages on your buildserver

sudo apt-get install -y autoconf automake bison bzip2 chrpath coreutils cpio curl cvs debianutils default-jre default-jre-headless diffstat flex g++ gawk gcc gcc-12 gcc-multilib g++-multilib gettext git git-core gzip help2man info iputils-ping java-common libc6-dev libegl1-mesa libglib2.0-dev libncurses5-dev libperl4-corelibs-perl libproc-processtable-perl libsdl1.2-dev libserf-dev libtool libxml2-utils make ncurses-bin patch perl pkg-config psmisc python3 python3-git python3-jinja2 python3-pexpect python3-pip python-setuptools qemu quilt socat sshpass subversion tar texi2html texinfo unzip wget xsltproc xterm xz-utils zip zlib1g-dev zstd fakeroot lz4 liblz4-tool

2 - Set python3 as preferred provider for python

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 2
sudo update-alternatives --config python
select python3

3 - Set your shell to /bin/bash.

sudo ln -sf /bin/bash /bin/sh

4 - modify max_user_watches

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf

sudo sysctl -n -w fs.inotify.max_user_watches=524288

5 - Disable apparmor profile

Currently due to this Ubuntu/bitbake issue: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2056555
This command must be entered after every restart of the build PC.

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

6 - Add user openbhbuilder

7 - Add your git user and email

git config --global user.email "[email protected]"

git config --global user.name "Your Name"

8 - Switch to user openbhbuilder

9 - Switch to home of openbhbuilder

cd ~

10 - Create folder openbh

mkdir -p ~/openbh

11 - Switch to folder openbh

cd openbh

12 - Clone oe-alliance git

git clone https://github.com/oe-alliance/build-enviroment.git -b 5.4

13 - Switch to folder build-enviroment

cd build-enviroment

14 - Update build-enviroment

make update

15 - Initialise the first machine so site.conf gets created

MACHINE=vuultimo4k DISTRO=openbh DISTRO_TYPE=release make  init

16 - Update site.conf

- BB_NUMBER_THREADS, PARALLEL_MAKE set to number of threads supported by the CPU
- add/modify DL_DIR = " location for build sources " to point to a location where you can save
  derived build sources, this will reduce build time in fetching these sources again.
- Avoid wasting disk space creating spdx packages: INHERIT:remove = "create-spdx"

17 - Building image with feeds e.g.:-

MACHINE=vuultimo4k DISTRO=openbh DISTRO_TYPE=release make image

18 - Building an image without feeds (Build time 1-2h)

MACHINE=vuultimo4k DISTRO=openbh DISTRO_TYPE=release make enigma2-image

19 - Building feeds only

MACHINE=vuultimo4k DISTRO=openbh DISTRO_TYPE=release make feeds
