Development Environment Setup¶
Before you can compile, you need to set up our development environment. You only need to do this once.
When you see
$ it means this is a shell command - run the command after the
$ but don’t include the
$. The shell commands may also be prefixed with
a folder name, meaning it needs to be run from a particular location, e.g.
foo/ $ ls means to run
ls from the
You need to install Git to retrieve the source code repository for the
Install GitHub for Windows, which includes a GUI for cloning Git repositories hosted at GitHub as well as a Bash terminal for using Git from the command line.
Mac OS X¶
Install GitHub for Mac, which includes a
GUI for cloning Git repositories hosted at GitHub and also installs the
git command line tools.
If you’re using Linux, you hopefully know what you’re doing and can install Git for your distro of choice. A couple of examples:
$ sudo apt-get install git
$ [sudo] pacman -S git
Clone the vi-firmware Repository¶
On Windows or Mac and you installed the GitHub app, open the vi-firmware repository in you browser and click the “Clone in Desktop” button.
If you are using
git from the command line, clone it like so:
$ git clone https://github.com/openxc/vi-firmware
Install Vagrant (Recommended for All Platforms)¶
On all platforms, we recommend using the included Vagrant configuration to get compiling as quickly as
possible. Vagrant is a tool that helps developers create and use identical
development environments. We include a
Vagrantfile in the repository that
Vagrant uses to create a small Linux virtual machine with all of the vi-firmware
dependencies installed. Once installed, you can open a shell in this VM just by
vagrant ssh. The
vi-firmware on the host OS (e.g. your Linux,
Windows or OS X machine) is shared to the Vagrant VM at the path
You can use whatever text editor or IDE you prefer in your native OS, and simply
do the compilation from within the VM.
- Install VirtualBox.
- If using Windows 7 (not required in Windows 8), add the VirtualBox tools to
PATH=%PATH%;c:\Program Files\Oracle\VirtualBox. If you aren’t sure how to edit your
PATH, see this guide for all versions of Windows. Log out and back in for the change to take effect.
- Install Vagrant.
- Navigate to the
vi-firmwarerepository in the GitHub app, click the gear icon in the top right corner and select “Open in Git Shell”.
- In the shell, run
vagrant upto initialize the Vagrant VM - this may take up to 10 minutes as it downloads and installs a number of dependencies in the VM.
- If the initialization completes with no errors, run
vagrant sshto open a shell in the VM.
vi-firmwaredirectly is shared with the VM in the default home directory. Move into that directory and compile away:
$ cd vi-firmware ~/vi-firmware $ fab reference build
You can edit the source code from your native OS and re-run
build from the Vagrant shell to compile (to compile for the reference VI, for
vagrant suspend to suspend the VM and
vagrant up again to
restore it - it will be much faster after the first run.
