Ikaros on OS X

Installation

1. Install latest Xcode from the App Store

The preferred way to install Ikaros is through the command line using the commands listed below.

2. Install Homebrew - The missing package manager for OS X

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3. Install dependencies

brew update && brew install cmake libpng jpeg-turbo ffmpeg

3. Download the source or clone the github repository

3a. Git: Cloning the ikaros-project on github

git clone http://github.com/ikaros-project/ikaros.git

3b. Download only the source in a tarball.

mkdir ikaros && curl -L https://github.com/ikaros-project/ikaros/tarball/master | tar zx --strip 1 -C ikaros

4. Build ikaros

cd ikaros/Build
cmake ..
make

5. Optionally generate an Xcode project file

cmake .. -G "Xcode"

Running Ikaros

At the shell prompt write the following:

> ikaros experimentfile.ikc

Here, "experimentfile.ikc" is the path to the experiment you want to run. You must set up your search path so that it includes the directory with the Ikaros binaries. This is usually the directory IKAROS/Bin. Command line options can also be specified here.

Note that the Ikaros binary must be placed at the correct location relative to the Source directory. If you move the binary from the Ikaros/Bin directory or set up your path so that Ikaros/Bin in in your search path, you need to change IKAROSPATH in IKAROS_System.h to point to the absolute location of the Ikaros directory.

Adding a module

While quite easy to add another module to the simulator it does involve a few steps. The idea is to create a new folder to hold the module, add the folder to the project, add a bit of documentation (you will thank yourself for doing this), and tell the system to add the module to the Ikaros.

  1. Create a new folder in UserModules. The easiest way to do this is to go to UserModules and copy the 'MyModule' folder; do not forget to rename the folder as well.
  2. Add your code as appropriate.
  3. Edit the ikc-file to add documentation.
  4. Add the following line to the code to install the module substituting the name of your module and its path in the source tree:
    			static InitClass init("MyModule", &MyModule::Create, "Source/UserModules/MyModule/");
    			

An example on how to write an IKAROS module can be found here.

Optional installs

Optionally Install freenect (http://openkinect.org/wiki/Getting_Started#Homebrew)

Freenect is used by the Ikaros module Kinect.

brew install libfreenect

Optionally Install ARToolKitPlus (https://launchpad.net/artoolkitplus)

ARToolKitPlus is used by the Ikaros module MarkerTracker.

curl -L https://launchpad.net/artoolkitplus/trunk/2.3.0/+download/ARToolKitPlus-2.3.0.tar.bz2 > ARToolKitPlus-2.3.0.tar.bz2
tar xfv ARToolKitPlus-2.3.0.tar.bz2 

Compile ARToolKitPlus:

cd {ARToolKitPlus}
cmake .
make
sudo mv include/ARToolKitPlus /usr/local/include
sudo mv lib/libARToolKitPlus.dylib /usr/local/lib/
