After 2 years, it is time to sit down and get substrate compiled again. The framework has changed a lot with literally thousands of commits around the clock. The architecture fundamentally changed, and many essential components are either further moved into higher abstract layers of libraries, or removed.

Here are the steps to get substrate compiled:

Make sure that all the dependencies are installed. (In this article, Fedora 36 is the chosen platform.)

Install Rust & nightly

# download rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# switch to the nightly version
rustup default nightly

# update
rustup update

Install WASM Compiler

rustup target add wasm32-unknown-unknown

Install Other Dependencies

protobuf-compiler

sudo dnf install protobuf-compiler

g++

sudo dnf install g++

clang

sudo dnf install clang

Get the source code

Clone the source from github

git clone https://github.com/paritytech/substrate.git && cd substrate

Compile

cargo +nightly build --release

Wait for the compile, (depends on how fast the machine is)

And at Last,

cargo run -- --dev

If everything is done right, the following strings will appear on the terminal.

And yes, compiling the stock node for local development is done here.

What's next ?

If someone only wants to do some smart contract development, the local test node is more than enough to meet the basic needs.

Or, if further modification to the blockchain itself is needed (for example, changing the consensus algorism) the sourcecode itself needs to be modified. And this will be written about in future articles.
