Downloading and Compiling under Linux

This page documents how to compile Arx Libertatis from https://github.com/lubosz/ArxFatalis.git under linux.

Specific instructions are given for a cleanly installed Ubuntu 10.10 AMD64 system but the procedure should be similar for other distributions. Please update this page if something is missing.

There is also a nice video how-to on linuxgamecast.com.

Setting Up the Build Enviroment

Your system must have the following dependencies installed:

• git
• cmake (version 2.8 or later)
• a gcc or clang toolchain
• zlib development libraries
• DevIL (http://openil.sourceforge.net/)
• Freetype (http://www.freetype.org/)
• OpenAL audio library (http://kcat.strangesoft.net/openal.html)
• Boost headers (http://www.boost.org/)

Your distribution's default repository might not have the DevIL package, so you may need to use a custom repository or build DevIL manually. See the project's Web site for details about obtaining it.

Example for apt-Based Systems

On an apt-based system such as Debian or Ubuntu, use:

sudo apt-get install git cmake g++ g++-multilib zlib1g-dev lib32z1-dev libfreetype6-dev libdevil1c2 libdevil-dev libopenal1 libopenal-dev mesa-common-dev libgl1-mesa-glx libgl1-mesa-glx-dev

Or, as root:

apt-get install git cmake g++ g++-multilib zlib1g-dev lib32z1-dev libfreetype6-dev libdevil1c2 libdevil-dev libopenal1 libopenal-dev mesa-common-dev libgl1-mesa-glx libgl1-mesa-glx-dev

Your package manager will probably prompt you to install other packages, so just say yes to those.

Known upstream bugs

There is a known rendering bug with the r600g gallum3d driver in mesa 7.11. The classic non-gallium driver is not affected. The bug is not present in mesa 7.10.3 and is fixed in mesa's git master.

Cloning the code repository

I prefer to work in a Code/ directory under my home directory.

cd ~/Code

You are now ready to clone the repository, type:

git clone https://github.com/lubosz/ArxFatalis.git

This creates a directory called ArxFatalis and downloads lubosz's current master branch of the source code from github.

cd ArxFatalis

Compiling

Now you should be ready to configure and compile. Run cmake:

cmake .

And now you should be able to compile with

make -j`getconf _NPROCESSORS_ONLN`

Alternatively, you can tell cmake to generate a unity build file, which might result in faster build times depending on your machine configuration. Run cmake like this:

cmake . -DARX_USE_UNITYBUILD=1

And make without the -j flag, since in effect there is only one file to build, named ub_arx.cpp

Running the executable

cd bin

./arx

You will need to obtain a copy of the data files from a commerical copy of Arx, or use the demo data files, put these in your bin directory and you are ready to go!

The game will automatically change all used files to lowercase on the first start. If you want to run the game with read-only data you need to do this manually.
