OpenZWave compile error: AssociationCommandConfiguration.cpp:191:85: error: ‘this’ pointer is null

[cedric2]

I failed to compile OpenZWave on my Arch linux system. I see this error:

As the OpenZwave project has stopped a long time ago the Domoticz project is promoting to use Zwave-JS-UI.

See wiki https://wiki.domoticz.com/Zwave-JS-UI

This wil probably not help you when compiling the current OpenZwave part in Domoticz.

Hello,

Did you use the version from domoticz repo?
https://github.com/domoticz/open-zwave

Looks last commit from Kiddigital was exactly about fixing the error you have!
