SID-02418: DBCacheContrib installation

Status:	Answered	TWiki version:	6.1.0	Perl version:	5.022004 (linux)
Category:	DBCacheContrib	Server OS:	Linux 3.13.0-042stab134.8 (x86_64-linux)	Last update:	6 years ago

I tried to install DBCacheContrib. First by configure, then from the command-line and manually editing LocalSite.cfg ($TWiki::cfg{Plugins}{DBCacheContrib}{Enabled} = 1;). However, DBCacheContrib is not shown in de Plugin list of configure.

The Twiki log says: "

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at /var/www/mytwiki.com/twiki/lib/TWiki/Contrib/DBCacheContrib/Array.pm line 266.
Compilation failed in require at /var/www/mytwiki.com/twiki/lib/TWiki/Contrib/DBCacheContrib/Map.pm line 23.

Discussion and Answer

Now my Warn Log says: TWiki::Plugins::DBCacheContrib could not be loaded.  Errors were: Can't locate TWiki/Plugins/DBCacheContrib.pm in @INC (you may need to install the TWiki::Plugins::DBCacheContrib module) (@INC contains:...........

BEGIN failed--compilation aborted at (eval 25) line 1.

The first problem can be eliminated by just omitting the defined() as suggested by the error message. This construct is fatal since Perl 5.22, and after a glance at the code I'm pretty sure that this is what the author intended.

As for the second problem, you should just check whether the plugin's files are available at the expected place under the lib directory of your TWiki installation, and if they are, whether they are readable by the web server's user id.

Thank you, Harald. I solved these problems with your advise. All this to to try to install TopicClassificationAddOn extention, which still gives me problems, see SID-02417.
