1 TWiki System Requirements

Server and client requirements

Low client and server base requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions. Many Plugins and contrib modules exist which enhance and expand TWiki's capabilities; they may have additional requirements.

Server Requirements

TWiki is written in Perl 5, uses a number of shell commands, and requires RCS (Revision Control System), a GNU Free Software package. TWiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements.

Resource Required Server Environment *
Perl 5.005_03 or higher (5.8.4 or higher is recommended)
RCS 5.7 or higher (including GNU diff)
Optional, TWiki includes a pure perl implementation of RCS that can be used instead (although it's slower)
GNU diff GNU diff 2.7 or higher is required when not using the all-Perl RcsLite.
Install on PATH if not included with RCS (check version with diff -v)
Must be the version used by RCS, to avoid problems with binary attachments - RCS may have hard-coded path to diff
GNU patch For upgrades only: GNU patch is required when using the TWiki:Codev.UpgradeTWiki script
Other external programs fgrep, egrep
Cron/scheduler • Unix: cron
• Windows: cron equivalents
Web server Apache is well supported; see TWiki:TWiki.InstallingTWiki#OtherWebServers for other servers
