We don't have legacy device support in display-caf currently.
(you would have figured this out if you'd done some searching of the source code to find where libqdMetaData is and under what conditions it gets built)
Someone's working on it, but it's not there yet.
Seriously, 90% of problems such as yours can be resolved via:
1) Searching Google
2) Searching through the source and (in this case) reading the makefiles
The support for legacy device is coming soon or will it take more time? ?(if you can answer)
Thanks for all. Great.
