Downloading and Compiling under macOS

ℹ️  This page describes compiling Arx Libertatis from source under Mac OS X and assumes some familiarity with the command-line. If you just want to play the game, it might be easier to grab a binary release or snapshot if available.

This page documents how to compile Arx Libertatis from https://github.com/arx/ArxLibertatis under Mac OS X.

Specific instructions are given for a cleanly installed Lion 10.7.3 system, but the procedure should be similar for other versions.

Setting Up the Build Environment

To download and compile Arx Libertatis you will need the following tools:

• Xcode Tested with 4.3, install the latest from the App Store (https://developer.apple.com/xcode/)
  • Install command line tools from Xcode, in Preferences -> Download
  • Set the path to the Xcode folder: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
• github for Mac Also install the command line tools (http://mac.github.com/)
• cmake should be build from source (http://www.cmake.org/)
• MacPorts (http://www.macports.org/)

Libraries

• SDL 1.2 (http://www.libsdl.org/)
• GLEW (http://glew.sourceforge.net/)
• DevIL (http://openil.sourceforge.net/)
• zlib (http://zlib.net/)
• Boost headers and program_options library (http://www.boost.org/)
• Freetype (http://www.freetype.org/)
• OpenGL Nothing to do... Framework is bundled with Xcode
• OpenAL Nothing to do... Framework is bundled with Xcode

I installed those using MacPorts... but you can probably obtain "native" versions too.

• zLib: sudo port install zlib
• freetype: sudo port install freetype
• devil: sudo port install libdevil
• boost: sudo port install boost
• qt: sudo port install qt4-mac
• sdl: sudo port install libsdl
• glew: sudo port install glew

Or as a single line:

sudo port install zlib freetype libdevil boost qt4-mac libsdl glew

Cloning the code repository

Using GitHub for Mac

Refer to http://mac.github.com/help.html :)

From the command line

First, go to where you want the ArxLibertatis directory to be located.

cd ~/Code

You are now ready to clone the repository, type:

git clone git://github.com/arx/ArxLibertatis.git

This creates a directory called ArxLibertatis and downloads the current source code from github.

cd ArxLibertatis

Compiling

Building CMake from source

The latest release of CMake (2.8.7) still has issues with Xcode 4.3, but it's been fixed in the development branch. You can build cmake from source to fix this:

git clone http://cmake.org/cmake.git
cd cmake
./configure
make
sudo make install

You're now ready to generate makefiles or an Xcode project. cd to the root of the arx repository

Makefiles

mkdir build
cd build
cmake ..
make

Xcode project

mkdir build_xcode
cd build_xcode
cmake .. -G Xcode
open ArxLibertatis.xcodeproj/

Running the executable

By default, the user directory for Arx on Mac is /Users/username/Library/Application Support/ArxLibertatis/

You will need to obtain a copy of the data files from a commercial copy of Arx Fatalis, or use the demo data files, put these in the directory mentioned above and you are ready to go! The game will automatically change all used files to lower-case on the first start. If you want to run the game with read-only data you need to do this manually.
