Installing on your board
Installing on Ubuntu
Here is a PPA for installing on Ubuntu Xenial or Bionic: https://launchpad.net/~mraa/+archive/ubuntu/mraa
sudo add-apt-repository ppa:mraa/mraa sudo apt-get update sudo apt-get install libmraa2 libmraa-dev libmraa-java python-mraa python3-mraa node-mraa mraa-tools
Running MRAA tools or applications on Ubuntu systems requires elevated permissions
(e.g. run with
Install on Arch Linux
There is an AUR package for mraa here: https://aur.archlinux.org/packages/mraa
Install on openSUSE
REPO="openSUSE_Tumbleweed" if test "$(arch)" == "aarch64"; then REPO="openSUSE_Factory_ARM" fi sudo zypper ar http://download.opensuse.org/repositories/hardware/$REPO/hardware.repo sudo zypper in mraa
Install on Fedora Linux
There is an mraa package in the main Fedora repository so it can be dnf installed in all recent Fedora releases. The Node.js and Python 3 bindings are packaged as separate packages.
sudo dnf install mraa nodejs-mraa python3-mraa
Installing for Node.js only
Note: Node.js 7.0.0+ is not currently supported unless compiling with a patched vesion of SWIG. See the corresponding section and document below.
You can also install just the node.js mraa module by using npm. You will need a C++ compiler and the node development headers, however it's not required to have SWIG installed. This works for node versions 6.x.x and prior.
npm install mraa
Note that installing mraa in this way builds mraa without json-c so you cannot use mraa_init_json_platform(). Also building this way means the mraa.node includes a static version of libmraa rather than relying on a dynamic library in /usr/lib.
Subplatforms (i.e. Firmata) have to be added manually with this kind of install from your application, as shown in this example.
