SID-00118: Perl 5.10 trashes my CalendarPlugin

Status:	Answered	TWiki version:	4.2.0	Perl version:	5.10
Category:	CalendarPlugin	Server OS:	Debian etch	Last update:	17 years ago

After foolishly updating my servers to perl 5.10 now my wiki's calendar plugin refuses to work at all. The error is "TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

missing HTML::CalendarMonthSimple"

I have installed this module and it still does not work. Any help!!!!

Discussion and Answer

Verify in the twiki/bin/view script which Perl is used, typically /usr/bin/perl. Verify that HTML/CalendarMonthSimple.pm is in one of it's Perl lib path.

I have verified every suggestion from above and still no sugar. I have to say this perl upgrade has been a disaster for me.

TIA for anymore help

Check the file permissions of CalendarMonthSimple.pm and its parent directories. They need to be readable by the webserver user.

With Debian Etch or Lenny you will need to use CPAN to install the HTML::CalendarMonthSimple.pm module required by CalendarPlugin. With the Debian package manager ( apt-get install ) , you will install either libtemplate-plugin-calendar-simple-perl containing Calendar/Simple.pm, or libhtml-calendarmonth-perl containing CalendarMonth.pm, but there is no debian package containing any file called CalendarMonthSimple as required by CalendarPlugin ( ie "missing HTML::CalendarMonthSimple").

Peter, the CalendarMonthSimple.pm is under perl and changing the permission did not do anything. Is it supposed to be under twiki?

Olivier, I had already tried both CPAN modules and debian packages and I still get the same error.

Anymore ideas,

See http://www.perlmonks.org/?node_id=691399 for how to keep perl 5.8 and perl 5.10 in two separate trees.

BTW, the Debian "Etch" system uses internally perl 5.8, and the Debian "Lenny" uses perl 5.10. Debian "Lenny" is now current stable release since last week . You will get perl 5.10 "out of the box" after a fresh Debian Stable "Lenny" install ( and then use tarball from http://twiki.org/download.html ) or after a system upgrade from "Etch" to "Lenny" ( I see you wrote "perl upgrade has been a disaster" : take a look at the debian "cruft" command : it will help you check what is installed with apt on your system and what is installed from cpan).
