# Development Environment Setup
|
|
|
|
A few basic steps are needed to get set up (skip to #5 if you already have Rust
|
|
installed):
|
|
|
|
1. Install [rustup](https://rustup.rs/). It's a toolchain manager for Rust (Linux | macOS | Windows). For installation, download the script with `$ curl -f https://sh.rustup.rs > rustup.sh`, review its content (e.g. `$ less ./rustup.sh`) and run the script `$ ./rustup.sh` (you may need to change the permissions to allow execution, i.e. `$ chmod +x rustup.sh`)
|
|
2. (Linux & MacOS) To configure your current shell run: `$ source $HOME/.cargo/env`
|
|
3. Use the command `rustup show` to get information about the Rust installation. You should see that the
|
|
active toolchain is the stable version.
|
|
4. Run `rustc --version` to check the installation and version of rust.
|
|
- Updates can be performed using` rustup update` .
|
|
5. Install build dependencies (Arch packages are listed here, your distribution will likely be similar):
|
|
- `clang`: required by RocksDB.
|
|
- `protobuf`: required for protobuf serialization (gRPC).
|
|
- `cmake`: required for building protobuf
|
|
- `git-lfs`: The Git extension for [Large File Support](https://git-lfs.github.com/) (required for EF tests submodule).
|
|
6. If you haven't already, clone the repository with submodules: `git clone --recursive https://github.com/sigp/lighthouse`.
|
|
Alternatively, run `git submodule init; git submodule update` in a repository which was cloned without submodules.
|
|
7. Change directory to the root of the repository.
|
|
8. Run the test by using command `cargo test --all --release`. By running, it will pass all the required test cases.
|
|
If you are doing it for the first time, then you can grab a coffee in the meantime. Usually, it takes time
|
|
to build, compile and pass all test cases. If there is no error then it means everything is working properly
|
|
and it's time to get your hands dirty.
|
|
In case, if there is an error, then please raise the [issue](https://github.com/sigp/lighthouse/issues).
|
|
We will help you.
|
|
9. As an alternative to, or instead of the above step, you may also run benchmarks by using
|
|
the command `cargo bench --all`
|
|
|
|
## Notes:
|
|
|
|
Lighthouse targets Rust `stable` but _should_ run on `nightly`.
|
|
|
|
### Note for Windows users:
|
|
|
|
Perl may also be required to build lighthouse. You can install [Strawberry Perl](http://strawberryperl.com/),
|
|
or alternatively use a choco install command `choco install strawberryperl`.
|
|
|
|
Additionally, the dependency `protoc-grpcio v0.3.1` is reported to have issues compiling in Windows. You can specify
|
|
a known working version by editing version in protos/Cargo.toml's "build-dependencies" section to
|
|
`protoc-grpcio = "<=0.3.0"`.
