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.
|
|
<
< |
| Perl |
5.005_03 or higher (5.6.1 recommended, 5.8.x does work in most cases, but see TWiki:Codev.IssuesWithPerl5dot8) |
| Non-standard Perl modules |
• Unix: Net::SMTP (or sendmail)
• Windows: Net::SMTP, MIME::Base64, Digest::SHA1
• Internationalisation: Unicode::MapUTF8 (only for non-ISO-8859-1 sites using TWiki:Codev.EncodeURLsWithUTF8 with Perl 5.6 or lower) |
| RCS |
5.7 or higher (including GNU diff)
Optional, but the all-Perl RCS replacement is not currently recommended for live sites - see TWiki:Codev.RcsLite |

| 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 |
| Other external programs |
fgrep, egrep |
|
|
<
< |
| Cron/scheduler |
• Unix: cron
• Windows: cron equivalents |
| Web server |
Apache 1.3 is well supported; Apache 2.0 is not recommended yet (see TWiki:Codev.IssuesWithApache2dot0).
For other servers, CGI support, authentication, extended path info required; also, the register script is likely to need significant changes |

Most of them will probably already be available in your installation. You can check version numbers with the configure script, or if you're still trying to get to that point, check from the command line like this:
perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'
<--
SMELL: perhaps put download link to TWiki:Plugins.CpanContrib? (which
also includes prebuilt versions of all of the CPAN modules used by
all of the plugins checked into SVN)
