Setting up the development environment

info

The environment will be setup for you automatically if you use Fluence CLI

To build Marine modules you need to install a CLI tool called marine that uses the Rust wasm32-wasi target and Marine environment to compile Wasm modules.

First, install Rust and supplementary tools:

sh
# install the Rust compiler and tools to `~/.cargo/bin`
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# add Rust tools to the current PATH
source $HOME/.cargo/env
# install the nightly toolchain 
rustup install nightly-2023-12-06

sh
# install the Rust compiler and tools to `~/.cargo/bin`
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# add Rust tools to the current PATH
source $HOME/.cargo/env
# install the nightly toolchain 
rustup install nightly-2023-12-06

To be able to compile Rust in Wasm, install the wasm32-wasi compilation target:

sh
# install wasm32-wasi target for WebAssembly
rustup +nightly-2023-12-06 target add wasm32-wasi

sh
# install wasm32-wasi target for WebAssembly
rustup +nightly-2023-12-06 target add wasm32-wasi

To be able to use generate subcommand of marine, install the cargo-generate tool:

sh
# install cargo-generate target for the marine tool
cargo install cargo-generate

sh
# install cargo-generate target for the marine tool
cargo install cargo-generate

Then, install marine and mrepl:

sh
# install marine
    cargo +nightly-2023-12-06 install marine
# install mrepl, it requires nightly toolchain
cargo +nightly-2023-12-06 install mrepl

sh
# install marine
    cargo +nightly-2023-12-06 install marine
# install mrepl, it requires nightly toolchain
cargo +nightly-2023-12-06 install mrepl
