Legato's Linux development host needs a few things to be set up before you can build Legato.

Install Linux Host Packages

Run the following to install necessary packages:

$ sudo apt-get install build-essential python python-jinja2 cmake git subversion libsdl-dev diffstat texinfo gawk chrpath wget cpio vim zsh bash ninja-build screen sshpass bc python-git unzip libxml2-utils

Optional packages include: vim zsh

Uninstall ccache

If ccache is installed, you must uninstall it so you can build some target images:

$ sudo apt-get remove ccache

Set Default System Shell

Some versions of Ubuntu default to dash system shell instead of bash, which will cause builds to fail. Run echo $0 to check your shell.

If you need to change it to use bash, run:

$ sudo dpkg-reconfigure dash

Answer "No" to the question.
