# Making Your Machine Ready for Building!
Before you can build anything, you are required to make your machine ready for building. For this you need to install a lot of libraries and modules. The most recommended Linux distribution is Ubuntu, so this example will focus on installing everything that is needed on Ubuntu.
# Installing Java
First, add the following Personal Package Archive (PPA): sudo apt-add-repository ppa:openjdk-r/ppa.
Then, update the sources by executing: sudo apt-get update.
# Installing Additional Dependencies
All required additional dependencies can be installed by the following command:
sudo apt-get install git-core python gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.8-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev openjdk-8-jre openjdk-8-jdk pngcrush schedtool libxml2 libxml2-utils xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev gcc-multilib liblz4-* pngquant ncurses-dev texinfo gcc gperf patch libtool automake g++ gawk subversion expat libexpat1-dev python-all-dev binutils-static bc libcloog-isl-dev libcap-dev autoconf libgmp-dev build-essential gcc-multilib g++-multilib pkg-config libmpc-dev libmpfr-dev lzma* liblzma* w3m android-tools-adb maven ncftp figlet
# Preparing the system for development
Now that all the dependencies are installed, let us prepare the system for development by executing:
sudo curl --create-dirs -L -o /etc/udev/rules.d/51-android.rules -O -L https://raw.githubusercontent.com/snowdream/51-android/master/51-android.rules
sudo chmod 644 /etc/udev/rules.d/51-android.rules
sudo chown root /etc/udev/rules.d/51-android.rules
sudo service udev restart
adb kill-server
sudo killall adb
Finally, let us set up the cache and the repo by the following commands:
sudo install utils/repo /usr/bin/
sudo install utils/ccache /usr/bin/
Please note: We can also achieve this setup by running the automated scripts made by Akhil Narang (akhilnarang), one of the maintainers of Resurrection Remix OS (opens new window). These scripts can be found on GitHub (opens new window).
