== Description ==
On this page you will learn how to setup the Nut/OS configurator and software Nut/OS depends on, on a Debian Linux machine.

The Nut/OS configurator is essential for developing and testing Nut/OS applications.

You have the choice to install different options of the development environment. For example an additional tool called Discoverer or several debugging solutions are available. As this is a quickstart guide, we will concentrate on the essential tools and packages. For a more detailed tutorial on all available options, please have a look at [http://ethernut.de/en/documents/debian.html Nut/OS Development on Debian] as well as the entire [http://ethernut.de/en/documents/index.html Documents section] of ethernut.de.

We will install the software in the following order:

* build-essentials (Linux C compiler etc.)
* wxWidgets
* Lua
* Nut/OS
* Cross Toolchains
** [[GNU AVR toolchain installation on Linux (Debian)]]
** [[GNU arm-elf toolchain installation on Linux (Debian)]]

Everything in this guide will happen in the Linux shell (Konsole).

All major topics are also covered in screencasts:

# [[Image:flashvideo.png|16px]] [http://ethernut.de/arc/screencasts/linuxinstall1.htm Screencast Part 1] build-essentials
# [[Image:flashvideo.png|16px]] [http://ethernut.de/arc/screencasts/linuxinstall2.htm Screencast Part 2] wxWidgets
# [[Image:flashvideo.png|16px]] [http://ethernut.de/arc/screencasts/linuxinstall3.htm Screencast Part 3] Lua
# [[Image:flashvideo.png|16px]] [http://ethernut.de/arc/screencasts/linuxinstall4.htm Screencast Part 4] Nut/OS
<br>

== build-essentials ==
[[Image:flashvideo.png|64px]] [http://ethernut.de/arc/screencasts/linuxinstall1.htm Screencast]

In this section we will install:
* build-essentials
* C compiler 4.1 or later
* Autoconf 2.61
* Automake 1.10

Most Debian distributions offer to install all basic tools for building Linux applications in one step:
<div class="konsole">
sudo apt-get install build-essential
</div>
If the package "build-essential" is not available to you, you may install or upgrade gcc and g++ by:
<div class="konsole">
sudo apt-get install gcc g++
</div>
Next you need to make sure to have a recent version of the GNU autotools installed.
<div class="konsole">
autoconf --version<br>
autoconf (GNU Autoconf) 2.61<br>
automake --version<br>
automake (GNU automake) 1.10
</div>
To install or upgrade, use:
<div class="konsole">
sudo apt-get install automake autoconf
</div>

== wxWidgets ==
[[Image:flashvideo.png|64px]] [http://ethernut.de/arc/screencasts/linuxinstall2.htm Screencast]

In this section we will install:
* wxWidgets 2.8 or later

You can either get the binary packages or build wxWidgets from the source code. The latter is required to build the Nut/OS Discoverer and is featured in [http://ethernut.de/en/documents/debian.html Nut/OS Development on Debian].

To install the binary packages, use:
<div class="konsole">
sudo apt-get install libwxgtk2.8-0 libwxgtk2.8-dev wx2.8-headers wx-common
</div>

== Lua ==
[[Image:flashvideo.png|64px]] [http://ethernut.de/arc/screencasts/linuxinstall3.htm Screencast]

In this section we will install:
* Lua 5.0
Whether any later version may work hasn't been tested yet.

The following command installs the necessary packages:
<div class="konsole">
sudo apt-get install lua50 liblua50 liblua50-dev liblualib50 liblualib50-dev
</div>
If no binary package is available for your Linux distribution, you can build Lua from the source. See [http://ethernut.de/en/documents/debian.html Nut/OS Development on Debian]

== Nut/OS ==
[[Image:flashvideo.png|64px]] [http://ethernut.de/arc/screencasts/linuxinstall4.htm Screencast]

Now we got everything on our Linux system to install the Nut/OS source package. Well, in fact the AVR or ARM toolchains are missing to build the Nut/OS libraries and sample applications. But this is done later (see Description) with the Nut/OS Configurator and therefore the platform specific cross toolchains are not yet required.

Thus, there is no binary package, we will build Nut/OS from sources.

It is highly recommended to create a project directory first and then download the latest ethernut-x.y.z.tar.bz2 from the download section into this directory.

<div class="konsole">
mkdir ~/ethernut
cd ~/ethernut
</div>
Now we download the latest Nut/OS version for Linux and store it in the folder just created. You can do this with your browser or by:
<div class="konsole">
wget http://ethernut.de/arc/ethernut-4.6.5.tar.bz2
</div>
The next step is to unpack the downloaded archive by:
<div class="konsole">
tar xjf ethernut-4.6.5.tar.bz2
</div>
We may later upgrade to a new version or we may concurrently work with different versions. Thus, it is most convenient to create a symbolic link 'nut' reffering on 'ethernut-4.6.5' :
<div class="konsole">
ln -s ethernut-4.6.5 nut
</div>
Now, change to 'nut', which will actually give us access to the content of the ethernut-4.6.4 folder:
<div class="konsole">
cd nut/
</div>
No it is time to start the configure script, to prepare the building process:
<div class="konsole">
./configure
</div>
You will get an output. Please check especially if these lines state 'enabled':

configure: nutconf tools enabled
configure: nutconfgui is enabled

If they do not, the Nut/OS configurator or it's Graphical User Interface will not get built! Please consult other help documents in this case.

The next command will build tools and documentation and will take several minutes to finish.
<div class="konsole">
make
</div>

Finally:
<div class="konsole">
sudo make install
</div>

== Cross Toolchains ==
Depending on your board you may proceed with either
* [[GNU AVR toolchain installation on Linux (Debian)]] for: Ethernut 1.3 ; Ethernut 2.1
or
* [[GNU arm-elf toolchain installation on Linux (Debian)]] for: Ethernut 3.0 ; Elektor Internet Radio
