[EP-tech] Re: Problem with the RSS plugin



Hi Seb,

I've tried all the options, but get the same error

./generate_apacheconf --verbose
Can't locate object method "new" via package "EPrints::Plugin::Export::ALLRSS" (perhaps you forgot to load "EPrints::Plugin::Export::ALLRSS"?) at /usr/share/eprints3/bin/../perl_lib/EPrints/PluginFactory.pm line 242.

My live eprints is 3.2.3, but I'm testing on 3.3.6.

Is there anything I need to edit at the beginning of the ALLRSS plugin ?

package EPrints::Plugin::Export::AllRSS;
use EPrints::Plugin::Export;
@ISA = ( "EPrints::Plugin::Export" );
use strict;

Regards,
Malcolm.

I don't think I said otherwise.

-> lib/plugins/... is global but won't be picked up locally unless
explicitly enabled in the local conf.

-> archives/{id}/.... appears local but the truth is that if you have
two repositories with the same "local" plugin only one will be loaded
globally (namespace clash) so if repo1 makes a change to their "local"
version, repo2 will inherit the change because at the end of the day,
the same process (modperl) cannot load twice the same package/module.

Having a plugin in archives/{id}/... does not guarantee it's localised
(that's why the bazaar doesn't install stuff there).

Seb.
