Dev-Setup

Toolchain

Install rustup

See rustup.rs to install rustup. It is recommended to use a non-root user.

cargo, rustc, rustup and other commands will be installed to Cargo's bin directory. The default path is $HOME/.cargo/bin, and the following examples will use this. You need to add this directory to your PATH environment variable.

  • Bash

    The setup script should have already added the following line to your $HOME/.profile:

    source "$HOME/.cargo/env"

  • Fish

    Run the following command:

    set -U fish_user_paths $HOME/.cargo/bin $fish_user_paths

Update rustup

rustup self update

Install stable toolchains

List all available components:

rustup component list

The following components is required and should have already been installed:

  • rustc
  • rust-std
  • cargo
  • rustfmt
  • clippy

llvm-tools is also recommended to be installed:

rustup component add llvm-tools

Install nightly toolchains

Install nightly toolchains:

rustup toolchain install nightly

List components in nightly channel:

rustup component list --toolchain nightly

Update toolchains

Run the following command to update the toolchains for all channel:

rustup update

Plugins for cargo

To install:

cargo install <crate name>

To update:

cargo install -f <crate name>

The following plugins is recommended:

  • cargo-expand

    Needed by IDE(at least JetBrains' rust plugin) to expand macros. The nightly toolchain is also required to run this.

  • cargo-audit

    Audit Cargo.lock for crates with security vulnerabilities.

  • cargo-binutils

    To run llvm-tools installed via rustup.

  • cargo-cache

    To clean cargo caches.

IDE

JetBrains

There is an official rust plugin for JetBrains IDEs.

PyCharm Community Edition is recommended as we also use Python scripts in this repo. Clion is needed if you want the DEBUG feature.

Dependent Tools and Libraries

Fast Install Guides

Debian based Linux distribution

It is recommended to use Debian based distro as your development platform.

apt-get install gcc pkgconf make capnproto
apt-get install curl jq xz-utils tar
apt-get install libssl-dev libc-ares-dev
# install lua5.4 or any other versions available on your system
apt-get install lua5.4-dev
apt-get install libpython3-dev
apt-get install python3-toml python3-requests python3-semver python3-socks python3-dnspyton
apt-get install python3-sphinx
apt-get install lsb-release dpkg-dev debhelper

RHEL based Linux distribution

The devel packages is contained in repos that is not enabled by default, you need to check the files under /etc/yum.repo.d/ and enable the corresponding repos. See EPEL Quickstart for more info.

Some scripting or testing tools may be unavailable.

# enable epel repo first
dnf install epel-release
dnf update

#
dnf install gcc pkgconf make capnproto
dnf install curl jq xz tar
dnf install openssl-devel c-ares-devel lua-devel
dnf install python3-devel
dnf install python3-toml python3-requests python3-semver
dnf install python3-sphinx
dnf install rpmdevtools rpm-build

MacOS

brew install pkgconf capnp
brew install openssl c-ares
brew install lua
# install python, or you can use the one provided by XCode
brew install python

Windows

# install rust toolchain
winget install Rustlang.Rust.MSVC
# install tools
winget install Kitware.CMake
winget install capnproto.capnproto
winget install NASM.NASM Ninja-build.Ninja
# install libraries
vcpkg install --triplet=x64-windows-static-md openssl
# build, c-ares need to be vendored, lua and python feature need to be disabled
cargo build --no-default-features --features quic,vendored-c-ares,hickory

Tips

  • Install WinGET without Windows App Store:

    # Download the new release from https://github.com/microsoft/winget-cli/releases
Add-AppxPackage -Path <xxx.msixbundle>

  • Install a standalone version of vcpkg:

    git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
# Then add the install path to `Path` and `VCPKG_ROOT` environment variable

FreeBSD

pkg install pkgconf capnproto
pkg install gmake # for vendored build of openssl
pkg install c-ares
# install lua5.4 or any other versions available on your system, and create a pkgconfig link
pkg install lua54
ln -s /usr/local/libdata/pkgconfig/lua-5.4.pc /usr/local/libdata/pkgconfig/lua5.4.pc
pkg install python3
# build, with vendored openssl
cargo build --vendored-openssl

NetBSD

pkgin install pkgconf capnproto
pkgin install libcares
# install lua5.4 or any other versions available on your system, and create a pkgconfig link
pkgin install lua54
ln -s /usr/pkg/lib/pkgconfig/lua-5.4.pc /usr/pkg/lib/pkgconfig/lua5.4.pc
# install python 3.11 or any other versions available on your system, and create links
pkgin install python311
ln -s /usr/pkg/bin/python3.11 /usr/pkg/bin/python3

OpenBSD

# install rust toolchain
pkg_add rust
# install capnproto from source
# install libs
pkg_add libcares
# install lua5.4 or any other versions available on your system, and create a pkgconfig link
pkg_add lua
ln -s /usr/local/lib/pkgconfig/lua54.pc /usr/local/lib/pkgconfig/lua5.4.pc
pkg_add python
# build, with vendored openssl
cargo build --vendored-openssl

Tips

  • Increase process memory limit size

    The datasize-cur limit in /etc/login.conf for login class staff need to be increased if the compilation failed with error out of memory.

Development Libraries

For g3proxy:

openssl >= 1.1.1
c-ares >= 1.13.0
lua
python3 >= 3.7

Development Tools

The tools for C development should be installed, including but not limited to:

gcc
pkg-config

If the c-ares version in the OS repo is too old, the following tools is also required:

Rpc Code Generator

We use capnproto rpc to communicate with the running daemon process:

capnproto

Testing Tools

The following tools are needed to run testing scripts:

curl

Scripting Tools

The following tools are used in scripts under directory scripts/:

git
jq
tar
xz

Scripting Libraries

We use python3 for more complicated scripts, the following packages are needed:

toml
requests
semver
PySocks
dnspython

Document Tools

We use sphinx to generate docs.
