Building (Linux)

Dependencies

Install the following packages before building (Debian/Ubuntu names shown):

sudo apt install \
  build-essential cmake \
  libglfw3-dev libgl-dev libglu1-mesa-dev \
  libopenal-dev libvorbis-dev \
  libpthread-stubs0-dev

On Arch/Manjaro:

sudo pacman -S base-devel gcc pkgconf cmake glfw-x11 mesa openal libvorbis glu

If you are on wayland, you may swap glfw-x11 to glfw-wayland for native wayland windowing instead of xwayland.

Configure & Build

Important

GCC 15 or newer is currently required to build this project. Ubuntu installations in particular may have older versions preinstalled, so verify your compiler version with gcc --version.

This project uses the Meson (with Ninja) as a build system and lld as a linker.

Install Tooling

1. Follow this Quickstart guide for installing or building Meson and Ninja on your respective distro.

2. Install the lld linker using your distro's package manager. This may be distributed as part of an LLVM toolchain.

   Debian/Ubuntu:

   sudo apt-get install lld

   RedHat/Fedora:

   sudo dnf install lld

   Arch/Manjaro:

   sudo pacman -S lld

Configure & Build

# 1. Configure a build directory (we'll name it `build`)
meson setup build

# 2. Compile the project
meson compile -C build

The binary is output to:

./build/Minecraft.Client/Minecraft.Client

Clean

To perform a clean compilation:

meson compile --clean -C build

...or to reconfigure an existing build directory:

meson setup build --reconfigure 

...or to hard reset the build directory:

rm -rf ./build
meson setup build

Running

In order to run the compiled binary, you must obtain a copy of a Windows64 build Common folder containing compiled media assets. The Common folder should be placed at the current working directory when you run the Minecraft.Client executable.

At this time, we don't have the necessary tools to build game resources without Visual Studio, so for the time being these can be obtained from the latest MinecraftConsoles nightly.

1. Download LCEWindows64.zip and extract.
2. Copy the Common directory to your current working directory.
3. Run Minecraft.Client.
