F.1.1 System Requirements

Note We strongly recommend using a Linux platform to work through these exercises, since this is currently the most extensively tested and most easily supported platform for the CCA tools. If this is not possible, or you have a specific need to use another platform while working through these exercises, please contact us at cca-tutorial@cca-forum.orgto discuss the best way to proceed. We're also interested to hear what platforms you would like to run your CCA applications on in the longer term in order to help us focus our porting and testing efforts.

The requirements to build the CCA tools on Linux platforms are listed below. Requirements for other platforms will vary somewhat.

• gcc > = 3.2

• Java Software Development Kit > = 1.4. The java commands must be in your execution path.

  Note We have on occasion observed problems with the Ccaffeine GUI interface hanging (most often while populating the palette as the GUI starts up). This seems to happen less often with version 1.4 than with more recent versions.

• Gnome XML C Parser Library (libxml2) - most recent Linux distro's already have it, regardless of whether Gnome is installed. Make sure you have the development package, e.g., libxml2-devel.

• A connection to the internet. (A network connection is required both to download the code cca-tools package and during the build process.)

• Python > = 2.3 built with --enable-shared (on platforms that support shared libraries), and Numerical Python (Numpy). If you have multiple versions of Python installed and prefer to have a version in your execution path that does not meet the criteria above, you should set the PYTHON environment variable to point to a suitable version for the CCA tools prior to configuring them. You can check the python version with python -V.
