Compiling Veloren

This section covers building Veloren from rust source with cargo and running it.

Note: all commands need to be run from the repository.

Required Libraries

On Windows you will need to install the following programs:

Fortunately, there is a quick way to install most of these

  1. Download and run the Visual Studio Build Tools and install:

    • C++ tools.
    • Windows 10 SDK.

  2. Open a PowerShell terminal and run the following commands:

    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Invoke-RestMethod -Uri https://get.scoop.sh | Invoke-Expression
scoop install cmake ninja python

    The first two lines install the Scoop package manager and the third line installs CMake, Ninja and Python through Scoop in one go.

On Linux you will need to have installed GTK3, Python and CMake.

On Gentoo you may require having to enable certain use flags for specific packages.

  • sys-devel/binutils (with the gold use flag to enable the ld.gold linker)
  • media-libs/mesa (with the vulkanuse flag)

On Debian systems additional libraries may need to be downloaded, below is a non-exhaustive list:

  • g++
  • libglib2.0-dev
  • libcairo2-dev
  • libasound2-dev
  • libpango1.0-dev
  • libatk1.0-dev
  • libgdk-pixbuf2.0-dev
  • libgtk-3-dev
  • libxcb-shape0-dev
  • libxcb-xfixes0-dev
  • libudev-dev
  • libxkbcommon-x11-dev
  • libxcb-xkb-dev

And a one liner to download and install them all:
sudo apt install g++ libglib2.0-dev libasound2-dev libcairo2-dev libpango1.0-dev libatk1.0-dev libgtk-3-dev libxcb-shape0-dev libxcb-xfixes0-dev libudev-dev libxkbcommon-x11-dev libxcb-xkb-dev

On Fedora systems additional libraries may need to be downloaded, below is a command to install them:
sudo dnf install gcc gcc-c++ binutils-gold cmake alsa-lib-devel libxkbcommon-x11-devel libudev-devel

On openSUSE Tumbleweed systems, additional dependencies may be needed:
sudo zypper in binutils-gold alsa-devel systemd-devel libxkbcommon-devel libxkbcommon-x11-devel

On macOS you only need to install cmake.
This can be done using either homebrew or macports. Using homebrew, enter brew install cmake or similarly, using macports enter sudo port install cmake.
Note: Do not use sudo with homebrew.

Note: Feel free to open an issue incase these dependencies are incorrect.

Compile and Run Veloren

Run this in a terminal to compile and run Veloren:

cargo run

To compile without running, use cargo build instead.

Note: The initial compilation will take from 5min up to 30min therefore grab a tea and some snacks and come back later.

Compile and Run Veloren Server

cargo run --bin veloren-server-cli

Logging output

We use tracing to collect logs. They can be filtered by setting the RUST_LOG environment variable to the respective level (error, warn, info, debug, trace).

For all available filtering options visit the docs.

Tip: this works both for the server and client

Optimized Release builds

By default debug builds are created which compile faster but run a bit slower than optimized release builds. Unlike many other projects, we've set them up so they're fast enough to be playable. If you want to get optimized builds, add the --release flag when calling cargo. Keep in mind that compiling release might be very slow!

If you want get familiar with cargo we recommend the Cargo Book.
