PyFerret is available pre-built as gzipped tar files for each of the systems listed below. The source code for PyFerret is also available as a gzipped tar file. See Installing or Building PyFerret for information on installing or building PyFerret from these files. At this time PyFerret cannot be built to run directly on Windows. See this WINDOWS_README file for more information on using a Linux version of PyFerret in a Linux virtual machine running under Windows.
The PyFerret 7.2 release, which encapsulates version 7.2 of Ferret, includes binaries for:
