SID-02249: Error installing Twiki - POSIX tzset not implemented

Status:	Asked	TWiki version:	6.0.2	Perl version:	5.24.0 ActivePerl
Category:	CategoryInstallation	Server OS:	Windows 2012 Server R2	Last update:	9 years ago

I´ve installed and configured twiki 6.0.2, but when I try to open the page http://localhost/do/view, there is the following error:

"TWiki detected an internal error - please check your TWiki logs and webserver logs for more information. POSIX::tzset not implemented on this architecture"

At Twiki log:

| 2016-09-14 - 13:06:18 | POSIX::tzset not implemented on this architecture at C:/www/twiki/lib/TWiki/Time.pm line 215.

Please, can any help me?

Discussion and Answer

What Perl engine do you use on Windows? Strawberry Perl on Windows does not support POSIX::tzset. If you use this, you will need to switch to an alternative Perl distribution. You can use ActivePerl which is free, and is the leading commercial-grade distribution of Perl; download from http://www.activestate.com/activeperl/downloads

See also TWikibug:Item7705.

Alternatively, DownloadTWikiVM and run it on VMware on Windows. This is straight forward and performs well.

Hi, I am using ActivePerl, version 5.24.0.2400 for Windows 64bits. I also tryed with ActivePerl 5.22.1 with the same error. What might be happening? Thanks.

After reading http://develop.twiki.org/~twiki/cgi-bin/view/Bugs/Item7705, as a workaround, I have wrapped tzset calls (at Time.pm) in an eval block (eval{tzset()};) and the page is displayed correctly. What consequences has this solution?

This workaround is harmless unless you rely on a plugin using the function TWiki::Time::formatTime() (see TWikiFuncDotPm), and you have with different local time zones in your TWiki user base.
