Like RHEL, Fedora and Ubuntu, ubinux is a solution of embedded platform operating system（including mass storage，small printers and scanners） based on Linux distribution.
Currently yocto-ubinux is managed on Github. You can get from there.
$ git clone https://github.com/ubinux/yocto-ubinux.git
Note
- Modify the value of the DOWNLOADS variable in the file setup_ubinux.sh to specify the download directory.
- Please refer to the build environment of poky5.2(Walnascar). In addition, the html5lib package needs to be installed to compile qtwebengine.
$ sudo pip install html5lib - Ubuntu 22.04 is recommended.
- More than 400G space needs to be prepared for build.
$ cd yocto-ubinux/
$ ./meta-ubinux/scripts/checkoutmetas.py
$ . setup_ubinux.sh ${machine} ${build_dir}
Note
- ${machine} - the config file’s name of each arch
$ cd meta-ubinux/conf/machine
$ ls
ubinux-armv8.conf
ubinux-x86-64.conf
- ${build_dir} - build directory of ubinux and it's set by the user
- The multlib option is enabled in ubinux-armv8.conf, so if you compile this machine, it will actually compile aarch64 and armv7 together.
Example set up build environment of X86_64
$ . setup_ubinux.sh ubinux-x86-64 ../build-ubinux-x86-64
- You can enter the build directory to set the environment variables.
$ cd ${build_dir} $ vi conf/local.conf - You can find the explanation of environment variables from https://wiki.yoctoproject.org/wiki/Main_Page
Enter the build directory to generate the toolchain of the specified arch.
$ bitbake meta-toolchain
Note
- The toolchains of each arch are stored in the corresponding directory of ${build_dir}/tmp/deploy/sdk/
Enter the build directory to generate the image of the specified arch.
$ cd ${build_dir}
$ bitbake ubinux-all
Note
- The rpms of each arch are stored in the corresponding directory of ${build_dir}/tmp/deploy/rpm
- Using dnf-plugin-tui(https://github.com/ubinux/dnf-plugin-tui) in toolchain generated in Chapter 3.4 to generate image.
