## 2.2 Requirements

To utilize Crystal Space you need at least the following resources.

Hardware: To fully utilize the 3D engine a 3D-accelerated graphics card is highly recommended. The minimum recommended processor on the x86 architecture is one of the i586 family (Pentium).

Operating System: You will need to be running a supported Operating System. Currently Crystal Space supports: Windows (32 and 64 bit), Unix (GNU/Linux, FreeBSD, etc.), and MacOS/X.

Development Environment: You may build Crystal Space yourself, or you may download a pre-built SDK package. If you are using the SVN version of Crystal Space, then you will need to build it yourself. To do so you will need a supported C++ compiler such as the GNU Compiler Collection (GCC - versions known to work well are 3.4 and above, with the exception of versions 4.0.0 and 4.0.1 which produce buggy code for Crystal Space) or Microsoft Visual C++, version 8.0 (aka .net 2005) and above (versions 6 to 7.1 are not supported). If you plan to use the scripting capabilities of Crystal Space you will also need an interpreter for each scripting language you use.

Crystal Space Package: The latest release of Crystal Space can be downloaded from:

http://www.crystalspace3d.org/main/Download

The release includes all of the source code, some pre-generated documentation, and a few example data files. Alternately, you can download the latest SVN snapshot, which is often a great improvement over the latest release, and often as, or more, stable.

http://www.crystalspace3d.org/cvs-snapshots/

You can also checkout the source directly from the SVN repository. Directions for doing this can be found here:

http://www.crystalspace3d.org/main/Subversion

External Dependencies: Crystal Space can use a number of optional libraries and tools to provide a more robust set of features. A brief list of the most important dependencies is presented here. See section External Libraries.

Z Library

  zlib is used for compression and archiving.

  http://www.gzip.org/zlib/

PNG Library

  libpng is used for loading Portable Network Graphics image files.

  http://www.libpng.org/pub/png/libpng.html

JPEG Library

  libjpeg is used for loading Joint Photographics Experts Group image files.

  http://www.ijg.org/files/

X Window System

  This is needed to enable graphical output on a number of Unix-like operating systems, most prominently GNU/Linux. It is not needed for Windows or MacOS/X.

OpenGL

  OpenGL is needed to provide accelerated 3D graphics on all platforms.

  Note that no special effort is usually needed to install the development components on Windows or MacOS/X.

Jam

  Jam is a `‘make’` replacement with a much more intuitive and expressive file format. Internally, the Crystal Space build system is predicated upon Jam, however Crystal Space also features a `‘make’` emulation layer which allows you to build and install the project using `‘make’`, so there is no strict need to download or install Jam. If, however, you plan to work on the Crystal Space build system or create your own external project based upon Jam, then you can download it from this location:

  ftp://ftp.perforce.com/jam/

  Jam documentation can be found at the Jam home page; see `‘Jam.html’`, `‘Jambase.html’`, and `‘Jamfile.html’`.

  http://www.perforce.com/jam/jam.html

  Jam is included pre-built in the `‘cs-winlibs’` convenience package (see section The “cs-winlibs” Packages), so Mingw and Cygwin users who use that package get Jam for free. Other users will want to build it from source code. For such users, once Jam has been downloaded, follow these simple steps to build and install it. These instructions illustrate Jam 2.5, which is current as of this writing.

      unzip jam-2.5.zip
      cd jam-2.5
      make
      ./jam0 install

  If you are a Unix user, then you will probably need to have administrator privilege to install the executable since it will be installed as `‘/usr/local/bin/jam’`. To gain administrator privilege, you can use the `‘sudo’` command:

      sudo ./jam0 install

  If you want to install Jam at a location other than the default, then set the `‘BINDIR’` variable to the directory in which you want it installed (this example shows it being installed in the user's private `‘$HOME/bin’` directory):

      ./jam0 -sBINDIR=$HOME/bin install
