Sirikata depends on quite a bit of external libraries. Dependencies gives a list of required and optional libraries and a brief description of how they are used.

When building Sirikata you have two options: handle installing dependencies yourself or use our install scripts or precompiled binaries (depending on platform and library) to help you build and install the required libraries. If you want to perform the installation or need to write new scripts for a new platform, see Dependencies for instructions on how to do so.

These instructions explain how to use our install script or precompiled binaries.

Note Some dependency files are quite large, especially the precompiled binaries. When you run the install commands, it may appear the script has hung, but its likely just checking out the packages.

Note Throughout we'll be using the standard set of dependencies, which includes support for graphics, embedded browsers, .NET scripting via Mono, Python scripting via IronPython, and physics simulation via Bullet. If you don't need all these features, for example because you are only running the space server, you can use a different dependency target. Where depends is used, you can replace the following to get a different set of dependencies:

  • minimal-depends - the minimal dependencies required to get the system building
  • minimal-graphics-depends - the minimal dependencies required to get 3D graphics working, i.e. to get a client running. Note that not all features of the client will be enabled by this
  • full-depends - all dependencies, enabling all features of the system, and enables use of root to install system packages


We use CMake on all platforms to check for dependencies and generate a build script. The Linux dependencies will install CMake from your system's package manager if you allow it to use root. Otherwise and for all Mac and Windows platforms, CMake is not installed automatically. You should use the install tool from the CMake website or install it using your system's package manager. CMake 2.4 or higher is required, CMake 2.6 or higher is preferred.


Because of their size, dependencies are stored in subversion repositories. If you want to use our automated dependency scripts, you'll need Subversion installed. It is installed on Mac by default, Linux users can use their distributions system package, and Windows users can either install it via Cygwin or use TortoiseSVN.

Simple Method: Makefile

On all platforms, if you have the right tools (make and subversion, on Windows provided by Cygwin) a Makefile is provided in the root directory which checks out and either builds or extracts dependencies to sirikata/dependencies/:

 cd sirikata/
 make depends

Windows Notes

The simple method requires Cygwin. All dependencies are installed locally in the Sirikata checkout. No root access is needed.

Note The Windows dependencies support Visual Studio 2008 and later, including Express editions. Visual Studio 2005 and earlier are no longer supported.

Without Cygwin (manual)

If you do not have Cygwin and do not want to install it, you can perform the steps manually. Using a subversion client, checkout 

to sirikata/dependencies/.

Go into the dependencies folder and unzip all of the packages directly into the dependencies directory. Make sure to select "Extract Here". If that option is not available, remove the name of the zip file from the end to indicate where to extract, so it just ends with "dependencies". The extracted directories should not have the same name as the zip files.


If you want .NET scripting support (the default scripting environment), you must install Mono manually. Install Mono 2.4 or later from [1] and invoke the installer .pkg. This installer will place a Mono.frameworks folder in /Library/Frameworks.


The install script expects an Ubuntu system, 8.04 or greater.

If you want to install the system package dependencies directly, issue the following command:

sudo apt-get install \
git-core cmake sed unzip zip automake1.9 nvidia-cg-toolkit jam g++ \
libzzip-dev libxt-dev libxaw7-dev libxxf86vm-dev libxrandr-dev libfreetype6-dev \
libxext-dev autoconf libtool libpcre3-dev flex bison patch libbz2-dev gawk \
libglu1-mesa-dev tofrodos libglut3-dev freeglut3-dev scons libexpat1-dev \
libgtk2.0-dev libnss3-dev libgconf2-dev gperf libasound2-dev subversion \
libtool autoconf ruby flex libgsl0-dev libssl-dev libspeex-dev libxss-dev \
libdbus-glib-1-dev libgnome-keyring-dev libxml2-dev libjpeg62-dev libcups2-dev

These packages should cover everything you need for the entire system, including the graphical client and all scripting plugins.

Building Sirikata

We use CMake to generate our build scripts. Make is used on Mac and Linux and Visual Studio is used on Windows to perform the actual build. All three builds follow the same basic steps:

  • Run cmake, possibly modifying the configuration.
  • Run your build tool.


Start up CMake and point both paths to sirikata/build/cmake. Hit configure twice. If you installed any dependencies in non-standard locations, point CMake to them now. To generate the build files, hit Generate. On Windows Vista or later you might want to change CMAKE_INSTALL_PREFIX to the directory where you want to install your compiled binaries and hit configure again, because by default CMake will generate Visual Studio project that will try to install compiled binaries into %PROGRAMFILES%. This requires administrative privileges, which is why build will fail (unless you run Visual Studio with administrative privileges or have disabled UAC).

Now browse to sirikata/build/cmake. Open Sirikata.sln and run Build All.

This should result in all libraries, plugins, and binaries in the sirikata/build/cmake/debug or sirikata/build/cmake release, depending on which configuration you built.


  • There aren't standard locations to search for dependencies on Windows. Obviously we've setup the build system to work cleanly with the dependency install script. The easiest way to get a manual installation of dependencies on Windows to work is to use the same layout as the install script, where all dependencies are located in sirikata/dependencies. If you don't do this, you will almost certainly need to manually specify the locations of some libraries in CMake.
  • The build is known to work for VS2008, for both regular and Express versions.
  • If you get error 0xc0000022, check the permissions of the sirikata top-level directory. If you used Cygwin's version of git, it will remove execute permissions for security purposes. You may enable execute by doing "chmod -R +x sirikata" in cygwin, or Granting yourself Full Control in Right Click->Properties->Security (make sure to click the Replace All Entries in Child Objects checkbox).

DLL Path under windows

In order to get Sirikata to find the required DLLs, you must copy all DLL files from these directories into the "build/cmake" directory:

  • dependencies\boost_1_37_0\lib
  • dependencies\installed-curl
  • dependencies\ogre-1.6.1\bin
  • dependencies\SDL-1.3.0\bin
  • dependencies\protobufs\bin

Note that Sirikata currently does not work in Windows 2000, due to the lack of a few raw input functions (RegisterRawInputDevice) that SDL 1.3 uses. This will hopefully be fixed in SDL at some point to make it use the old DirectX raw input system.

Mac and Linux

For convenience we provide a top level makefile which performs the standard build operations. If you want a default build and have used the install script for dependencies, do:

 cd sirikata/

If you'd like to run the build manually, do the following (essentially what is in the makefile):

 cd sirikata/build/cmake
 cmake . [-DCMAKE_BUILD_TYPE=Debug|Release]

To interactively adjust settings, for instance to point CMake to a different version of libraries:

 cd sirikata/build/cmake
 ccmake .

When the build completes you should have the libraries, plugins, and binaries in sirikata/build/cmake.

Snow Leopard

Note Snow Leopard support is a work in progress. These instructions may or may not work. If you find these do not work, please let us know.

With the release of Apple's Snow Leopard (10.6) operating system comes the opportunity to have software compiled for two different architectures running on the same machine. These are the 32-bit i386 and the 64-bit x86_64 (k8). Though the Intel hardware has always had the capability to run in a 64 bit address space prior to 10.6, the operating system didn't support it. Unfortunately, the default architecture is 64, but not all libraries and dependencies are 64-bit savvy, so it is best to compile for the 32 bit architecture.

Upgrade Xcode and Developer Tools

First, you need to upgrade the Xcode tools to 3.2.x. On the Snow Leopard DVD, under “Optional Installs”, install “Xcode.mpkg” to get 3.2. Use all default options. Alternatively, you may want to log in and download the latest Xcode at

This is highly recommended, because the initial Xcode 3.2 seems to get into a spinning beachball state a bit too frequently. Xcode 3.2.1 seems to be a better multitasking citizen.

Upgrade MacPorts

Then, you need to upgrade Macports. Get the Snow Leopard disk image at

After successful installation, make sure to run

sudo port selfupdate

Then, you need to remove all of your ports, and reinstall new ones. See the documentation at:

By default, the libraries and frameworks are compiled for the 64-bit architecture, so you need to use the +universal flag to produce both 32- and 64-bit variants.

sudo port install cmake +universal zlib +universal bzip2 +universal boost +universal sqlite3 +universal
Regenerate Makefiles
cd build/cmake
rm CMakeCache.txt
cmake . -DCMAKE_CXX_FLAGS="-arch i386"

Now, you should be able to build.

Mac XCode Project

Many mac developers prefer to use the XCode programming environment. To do this, cmake will need to be configured to use XCode

Steps are:

  1. test -d build/cmake/Debug || mkdir build/cmake/Debug
        1. The directory for XCode build products.
  2. python build/cmake/Debug/scene.csv scene.db
        1. Generate a scene for use by the XCode project.
  3. cd build/cmake
  4. ln -s ../../dependencies/Frameworks Frameworks
        1. To fix brittle paths in Xcode project.
  5. cmake -G Xcode .
  6. cd Debug
  7. ln -s ../Sirikata.Protocol.dll Sirikata.Protocol.dll
  8. ln -s ../Sirikata.Runtime.dll Sirikata.Runtime.dll
  9. cd ..
  10. Launch Xcode
  11. Open Sirikata.xcodeproj
  12. Edit project settings
        1. General tab
        2. Choose project root
        3. Select build/cmake directory. Click OK. Value should just be <Project File Directory>.
              1. This fixes a problem that prevents debugger from working.
  13. Project menu
        1. Select active target ALL_BUILD
        2. Select active project executable cppoh
        3. Select active build configuration Debug
  14. Close XCode to save the project
  15. Reopen Sirikata.xcodeproj
  16. Build it
  17. Debugger
        1. Confirm that you can set a break point.
        2. Run debugger
        3. Confirm that it stops at a break point.
        4. Confirm that it displays source code.
        5. (trouble shoot back to step 10)

Running Sirikata

Assuming the previous steps have completed successfully, you should have a few binaries built and you are ready to run Sirikata.
