Building failed when trying to change consensus mechanism from manual-seal to aura

[maancham]

Hi,

We have a fresh build of substrate node forked from this repository. We are currently trying to implement aura consensus mechanism. We found these two commits: Changed consensus to manual-seal #42 and reverted applied changes to have aura. Unfortunately, we are getting all sorts of errors like:

not found in "sys" type Event = Event ^^^^^^ not a member of trait "pallet_gradpa::Config"

We tried using cargo clean and cargo update to address any dependency issues. But no luck so far. Since we did not find any other useful links on aura (and BABE) implementation details, do you have any advice?
