Wasn't sure where to ask so I ask here. Seems just a good a place as any, short of starting a new thread.

I am trying to build an existing Harmattan application on Sailfish. I have absolutely zero time and incentive to faff around with SDKs so I am building it on the phone itself. Please bear that in mind and please, please, please avoid answers of the "use the SDK" type. If I cannot build it on the phone itself, I cannot build it at all. Simple as that.

So, here it goes. I have the Harmattan sources. QMake gives me:

I am sure there will be more problems later but one at a time.
'pkcon search name declarative' gives me a loooong list, containing amongst others...

I assume I need the 'sources' package but how do I get it on the phone?
(Yes, I am such a noob! )
