= Introduction =
This page is dedicated to explaining how to install {{OpenFOAM}} {{version1.7.1}} in Ubuntu.

If you do not yet feel comfortable using Linux, then perhaps you better first read the page [[Installation/Working with the Shell|Working with the Shell]] and train a bit with the shell/terminal environments, so you can have a better perception of the steps shown below.

= ''Copy-Paste'' steps =

A few notes before you start copy-pasting:

# Lines that start with <tt>#</tt> don't have to be ''copy-pasted''. They are just comments to let you know what's going on.
# One wrong character is enough for breaking this guide, so make sure you can read the characters properly or that the installed language system does not break the copied characters!


== Ubuntu 12.04 ==

Here you have at least two choices:
* You can install the Deb packages, which provide a quick and easy way for having a working installation of OpenFOAM 1.7.1. This is the quickest solution for beginners and instructions are provided here: [http://openfoam.org/download/1-7-1-ubuntu/ Ubuntu Deb Pack Installation]
** On Ubuntu 12.04, you'll have to replace the line: <pre>VERS=`lsb_release -cs`</pre> With this one: <pre>VERS=maverick</pre>
** Note: If are getting an error when trying to install the packages for Ubuntu, then check this FAQ: [[FAQ/Installation and Running#Why am I not able to install the official OpenFOAM Deb packages on Ubuntu ?|Why am I not able to install the official OpenFOAM Deb packages on Ubuntu ?]]
* You can install from source, by either:
** Following the official instructions from here: [http://openfoam.org/download/1-7-1-source/ Source Pack Installation] - Caution: these instructions are outdated for Ubuntu 12.04.
** Or by following the detailed step-by-step instructions below...

Steps:
<ol>
{{Installation/Linux/SwitchToRoot}}
{{Installation/Linux/AptGetUpdate}}

<li>Install the necessary packages:
<bash>apt-get install build-essential cmake flex bison zlib1g-dev gnuplot libreadline-dev \
libncurses-dev libxt-dev gcc-4.5 g++-4.5 binutils-dev
</bash>
</li>

<li>Download and unpack (here you can copy-paste all in single go):
<bash>#OpenFOAM downloading and installation
cd ~
mkdir OpenFOAM
cd OpenFOAM
wget "http://downloads.sourceforge.net/foam/OpenFOAM-1.7.1.gtgz?use_mirror=mesh" -O OpenFOAM-1.7.1.tgz

wget "https://raw.github.com/OpenCFD/OpenFOAM-1.7.x/master/etc/settings.sh" -O etc/settings.sh
</bash></li>

<li>For building OpenFOAM itself, it depends on whether you have installed the i386 or x86_64 architecture of Ubuntu. To check this, run:
<bash>uname -m</bash>
Now, accordingly:
<ul {{NoIndentStyle}}>
<li>For i386:
<bash>#update rules' files
