The easiest way to run mspgcc in ubuntu is to install it by typing:

```
sudo apt-get install gcc-msp430
```

That will install a sensible toolchain for msp430-gcc. If for any reason you need to build the toolchain by yourself, then this script will help you accomplish this.

Install mspgcc in Ubuntu
========================

This repo has a script to install [mspgcc uniarch](http://mspgcc.sourceforge.net/) (C compiler for [msp430](http://www.ti.com/msp430) microcontrollers) in Ubuntu, along with some utilities for it. It installs the LTS (Long Term Support) version of the compiler, 
which is the most up-to-date version. Currently, this is LTS 20120406. __Update__: There are special branches for different mspgcc flavors:
  * The 'master' branch was tested with Ubuntu 14.04, using gcc 4.8.2.
  * Branch '20120911' contains a script to install the 20-bit development compiler, based on gcc 4.7.
  * Branch 'redhat' builds the [RedHat version of mspgcc](http://msp430-gcc-users.1086195.n5.nabble.com/MSP430-GCC-goes-Red-Hat-td1176.html).

Checkout those branches for specific instructions:

git checkout 'branchname'

## Special considerations for Ubuntu versions

### 12.04

Use commit `6df3dabca`: `git checkout 6df3dabca`.

### 14.04

Use master branch

### 16.04

Install and use gcc-4.7:

```
sudo apt-get install gcc-4.7
sudo update-alternatives --install /usr/bin/gcc-4.7 50
sudo update-alternatives --set gcc /usr/bin/gcc-4.7
```

Remember to switch back to your previous version of gcc after running this script.

## Building ##

To build mspgcc you will need to install _at least_ the following packages:

sudo apt-get install patch ncurses-dev build-essential bison flex libgmp3-dev libmpfr-dev libmpc-dev texinfo zlib1g-dev libusb-dev libreadline6-dev libz-dev

The installation folder is `/usr/local/msp430` (modifiable in the script). If you already have contents in this folder I recommend you to move it to a backup folder, i.e.:

sudo mv /usr/local/msp430 /usr/local/msp430-backup

To install go to the console and run:

git clone https://github.com/jlhonora/mspgcc-install.git
    cd mspgcc-install
    ./install-all

You should be careful to watch for error messages.

If everything goes well, I recommend you to add the msp430-gcc path to your environment path. For that, append the following line to your `.bashrc`:

export PATH=/usr/local/msp430/bin:/usr/local/msp430/lib:/usr/local/msp430/include:$PATH

Also paste it in the command line to use the modified $PATH right away.

## Testing ##

To check that everything is ok, type:

cd tests
    msp430-gcc -mmcu=msp430g2553 hello_world.c

The mmcu option should match the microcontroller you will be using.

## Installing the file in a Launchpad board ##

The previous command should generate a compiled file named `a.out`, ready to install in the microcontroller. If you have a [MSP430 Launchpad Board](http://www.ti.com/ww/en/launchpad/msp430_head.html) at reach you can install the compiled file with [mspdebug](http://mspdebug.sourceforge.net/). It can be installed with the `install-mspdebug` script (`$ ./install-mspdebug`) or by running the following commands:

sudo apt-get install libusb-dev libreadline6-dev
    ./install_mspdebug

Update: If you're using Ubuntu 13.04 I strongly recommend installing mspdebug via the `install-mspdebug` script, since there's a modification that should be made to the source for it to compile successfully.

USB permissions should be added to the FET interface of the Launchpad ([source](https://github.com/sergiocampama/Launchpad#mspdebug-usb-permissions)). As root, create the file `/etc/udev/rules.d/71-persistent-msp430.rules` and add `AATR{idVendor}=="0451", ATTRS{idProduct}=="f432", MODE="0660", GROUP="plugdev"` . Then run

sudo addgroup YOUR_USERNAME plugdev
    sudo restart udev

If everything goes well, you can install the compiled program:

sudo mspdebug rf2500 "prog a.out"

This should also work with the [MSP-EXP430F5529 board](http://www.ti.com/tool/msp-exp430f5529), but changing the compile options to `-mmcu=msp430f5529`.

## 20-bit support ##
To install the development version of the compiler, do:

git checkout 20120911

And then follow the instructions above.
