This Tutorial assumes that you are using x86. If you are using amd64 just substitute the keyword.

== Prerequisites ==

Orxonox uses Ogre with CEGUI for rendering, OIS for input handling, eNet for network support Boost for threading and cMake as build-system. You will have to install these packages. Every needed package is in portage.

Add USE-Flags:
{{{
# echo "dev-games/cegui devil expat" >> /etc/portage/package.use
# echo "dev-games/ogre cegui devil lua threads" >> /etc/portage/package.use
}}}
Some packages are unstable, for portage to use them do:
{{{
# echo "dev-games/ogre-1.4.5 ~x86" >> /etc/portage/package.keywords
# echo "dev-games/ois-1.0 ~x86" >> /etc/portage/package.keywords
}}}
Then, emerge the packages. CEGUI and Boost are dependencies of Ogre, so they will not be installed explicitly. TCL is also mandatory.
{{{
# emerge cmake ogre ois tcl
# CFLAGS="-fPIC" emerge enet
}}}
eNet needs to be compiled with -fPIC to be included as shared library ([wiki:people/NicolasSchlumberger nico]: Dec '07).

== Getting the Source Code ==
If you have not done so already, you need to install Subversion on your system. To do this, make sure that you have '''ssl''' included in your '''make.conf''' file:, which is normally located at '''/etc/make.conf''':
{{{
 ...
 USE="..., ssl, ..."
 ...
}}}
Now emerge subversion:
{{{
# emerge subversion
}}}

Now proceed by following the steps described on the [wiki:LinuxSource building] page.

== Development with your favorite IDE ==
CMake can create project files for [wiki:code/tools/KDevelop3 KDevelop], [wiki:code/tools/EclipseIDE Eclipse] or [wiki:code/tools/CMake#UsingCMakegeneratedprojectfiles Code::Blocks] for coding. Click the links for further information.
