3.1.3 Software

In addition to the above platform requirements, you may need to install one or more of the following software packages:

• All Harvest servers require: Perl v4.0 or higher (v5.0 is preferred).
• The Harvest Broker and Gatherer require: GNU gzip v1.2.4 or higher.
• The Harvest Broker requires: an HTTP server

If you want to build Harvest from the source distribution rather than using one of the binary distribution, then you may need to install one or more of the following software packages:

• Compiling Harvest requires: GNU gcc v2.5.8 or higher
• Compiling the Harvest Broker requires: flex v2.4.7 and bison v1.22.

The source for Perl, gcc, gzip, flex, and bison are available at the GNU FTP server. Information about various HTTP server software packages is available at the Sunsite FTP server.
