Find the source I have been working with at: https://github.com/al3mart/substrate-node-template/tree/al3mart/runtime-featuregated.
While building a node using the feature-gated runtimes added in https://github.com/paritytech/substrate/pull/11818 I encounter the following compilation errors.
- Scenario 1
construct_runtime! includes a pallet decorated by #[cfg(feature = "template")].
Building with: $ cargo build --release results in
--- stderr
Compiling node-template-runtime v4.0.0-dev (/home/ale/Projects/substrate/substrate-node-template/runtime)
error[E0277]: the trait bound `Event: From<pallet_template::Event<Runtime>>` is not satisfied

270 | type Event = Event;
| ^^^^^ the trait `From<pallet_template::Event<Runtime>>` is not implemented for `Event`

= help: the following other types implement trait `From<T>`:
<Event as From<frame_system::Event<Runtime>>>
<Event as From<pallet_balances::Event<Runtime>>>
<Event as From<pallet_grandpa::Event>>
<Event as From<pallet_sudo::Event<Runtime>>>
<Event as From<pallet_transaction_payment::Event<Runtime>>>
note: required by a bound in `pallet_template::Config::Event`
--> /home/ale/Projects/substrate/substrate-node-template/pallets/template/src/lib.rs:30:15

30 | type Event: From<Event<Self>> + IsType<<Self as frame_system::Config>::Event>;
