Follow these steps in order to use Energia for the Launchpad MSP-EXP430G2 board.

Install package java-rxtx from the official repositories.

Create a udev rule:

    /etc/udev/rules.d/10-launchpad.rules

    SUBSYSTEM=="usb",ATTR{idVendor}=="0451",ATTR{idProduct}=="f432",GROUP="dialout",MODE="0660"

Create `dialout` group:

    # groupadd dialout

Add your user to groups `lock`, `uucp` and `dialout`:

    # usermod -a -G lock,uucp,dialout $(whoami)

Download energia for your architecture (32bit or 64bit) from www.energia.nu and decompress it.

Change directory to the folder `lib`:

    $ cd ./energia-0101E0012/lib/

Create a backup of these files (or delete them):

    $ mv librxtxSerial.so librxtxSerial.so.bak
    $ mv librxtxSerial64.so librxtxSerial64.so.bak
    $ mv RXTXcomm.jar RXTXcomm.jar.bak

Create links to the Arch Linux version of java-rxtx:

    $ ln -s /usr/lib/librxtxSerial.so "librxtxSerial.so"
    $ ln -s /usr/lib/librxtxSerial.so "librxtxSerial64.so"
    $ ln -s /usr/share/java/rxtx/RXTXcomm.jar "RXTXcomm.jar"

Reboot (or restart udev, log out and log in).

Plug your launchpad and start energia.
