# Building the ISO Perform the following steps to install the packages on Ubuntu: 1. Install the packages: ``` sudo apt-get -y install bison gawk g++ createrepo python-aptdaemon genisoimage texinfo python-requests libfuse-dev libssl-dev uuid-dev libreadline-dev kpartx git bc ``` 1. Get Docker: ``` wget -qO- https://get.docker.com/ | sh ``` 1. Install pip and docker 2.3.0 ``` sudo apt install python3-pip pip3 install docker==2.3.0 ``` If you encounter an error for LOCALE when you run these commands, then export the following variables in the terminal: ``` export LC_ALL="en_US.UTF-8" export LC_CTYPE="en_US.UTF-8" ``` 1. Make the ISO. The example below assumes that you checked out the workspace under `$HOME/workspaces/photon`: ``` cd $HOME/workspaces/photon sudo make iso ``` **Result** This command first builds all RPMs corresponding to the SPEC files in your Photon repository and then builds a bootable ISO containing those RPMs. The RPMs thus built are stored under `stage/RPMS/` directory within the repository, using the following directory hierarchy: ``` $HOME/workspaces/photon/stage/: ├──RPMS/: ├──noarch/*.noarch.rpm [Architecture-independent RPMs] ├──x86_64/*.x86_64.rpm [RPMs built for the x86-64 architecture] ├──aarch64/*.aarch64.rpm [RPMs built for the aarch64 (ARM64) architecture] ``` The ISO is created at `$HOME/workspaces/photon/stage/photon.iso`.
