[TYPO3-english] caldav extension not working

[Jean-Paul Chaput]

Hello Forum,

I'm trying to setup the caldav extension, but caldav.php fails running with the error:

Fatal error: Class 'TYPO3\CMS\Core\Core\ApplicationContext' not found in /usr/local/share/typo3_src-7.6.15/typo3/sysext/core/Classes/Core/Bootstrap.php on line 90

I've followed the all the steps in the documentation but got stuck at the execution of the
caldav standalone php script

My configuration is:

* NetBSD 7.1
* Typo3 7.6.15
* Calendar Base 1.11.1
* CalDAV 1.0.2

Best regards,
