OpenBh buildserver requirements:
Ubuntu 20.04.2 LTS (Kernel 5.4.0) 64 Bit Server OS
minimum hardware requirement for image build (building feeds may require more):
RAM: 16GB SWAP: 8GB 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:
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-8 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
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 dpkg-reconfigure dash
When asked: Install dash as /bin/sh?
select "NO"
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 - Add user openbhbuilder
sudo adduser openbhbuilder
6 - Switch to user openbhbuilder
su openbhbuilder
7 - Switch to home of openbhbuilder
cd ~
8 - Create folder openbh
mkdir -p ~/openbh
9 - Switch to folder openbh
cd openbh
10 - Clone oe-alliance git
git clone https://github.com/oe-alliance/build-enviroment.git -b 5.1
11 - Switch to folder build-enviroment
cd build-enviroment
12 - Update build-enviroment
make update
13 - 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.
14 - Finally you can start building a image For example:-
MACHINE=vuultimo4k DISTRO=openbh DISTRO_TYPE=release make image
