Class ... not found

Warning: Class 'SMW\Store' not found in C:\xampp\htdocs\mw\extensions\SemanticMediaWiki\SemanticMediaWiki.php on line 61

Those message are related to due to the require_once( "$IP/extensions/Validator/Validator.php" ); setting in LocalSettings.

Solution

Remove require_once( "$IP/extensions/Validator/Validator.php" ); from LocalSettings, Validator will be automatically included.

Notice: Use of undefined constant SMW_NS_PROPERTY

SNW-NS constants are delayed due to $smwgNamespaceIndex being a prerequisite and its initialization has to happen first.

For details, see Bug 58190 and Bug 57760

Solution

Bug 58182

What is the status of this?

Oops, I was totally unaware of this. Must have slipped through the regular e-mail-tsunami. I will add a section to Help:Installation.

[kghbln]

Done with this diff. May be closed for now and reopened in case any further issue arises. I am watching this now.

Fatal: Call to undefined function enableSemantics() in line xyz

This is related to James' comment.

This happens for MW ≤ 1.21.x if you move the declaration of enableSemantics() over the actual initialization of SMW which is done with include "extensions/ExtensionInstaller/ExtensionInstaller.php";.

Solution

include "extensions/ExtensionInstaller/ExtensionInstaller.php";

must be set prior to

enableSemantics()

All other requirement still apply (custom semantic ns index, custom namespaces, etc.)

I'm a bit confused at why this is posted here.

[kghbln]

Well this is the issue for collecting all cases related to "SMW 1.9 upgrade troubleshooting guide when installing with Composer"

[JeroenDeDauw]

You can just add it to the section no? James created this presumably because he did not know where to put it.

[kghbln]

Well, until now I expected all issues to be listed here for me to add it to the wiki. It was just coincidental that I was the first to come up with this issue. E-mail are good, too if you like.

[JeroenDeDauw]

I simply fail to understand why you would create a note saying "I should add xyz to the wiki" rather than actually adding xyz to this wiki. It seems the same amount of effort to do this one step.

[kghbln]

This is about how these issues are reported and than to be added to the wiki. If you or James want to add it directly to the wiki or send me an e-mail instead you may very well do so. In this case this issue is not needed for notification.
