Topic on Extension talk:SemanticDependencyUpdater

Hi, I'm trying to get this running on my MW 1.30/SMW 2.5.6 Site and after performing the following steps:

1. created the "Property:Semantic_Dependency" property as [[Has type::Text]]
2. and then unzipping the extension archive to my extension folder
3. adding "wfLoadExtension( 'SemanticDependencyUpdater' );" to "LocalSettings.php"

My 1.30 wiki threw the following exception:

Fatal error: Uncaught exception 'Exception' with message 'SemanticDependencyUpdater requires SemanticMediaWiki to be installed.' in /opt/htdocs/mediawiki/includes/registration/ExtensionRegistry.php:261 Stack trace: 
#0 /opt/htdocs/mediawiki/includes/registration/ExtensionRegistry.php(148): ExtensionRegistry->readFromQueue(Array) 
#1 /opt/htdocs/mediawiki/includes/Setup.php(40): ExtensionRegistry->loadFromQueue()

#3 /opt/htdocs/mediawiki/index.php(40): require('/opt/htdocs/med...') 
#4 {main} thrown in /opt/htdocs/mediawiki/includes/registration/ExtensionRegistry.php on line 261

it's weird because SMW *is* installed (2.5.6) and it does work great.

Any ideas on why this error is occuring?

could this be a permissions problem with my /includes folder?

did you check, if SDU is registered in LocalSettings after SMW?

I'll do that today and let you know. More soon.
