Planned platforms to be supported:

Linux (~85%)
Emscripten (not started)
PS3
macOS (not started)
iOS (not started)
Android (not started)

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, swap glfw-x11 to glfw-wayland, but its doesn't matter cuz xwayland got yourself covered

Configure & Build

# 1. Configure (only needed once, or after CMakeLists changes)
cmake .

# 2. Build (use -jN with your core count)
make -j$(nproc)

The binary is output to:

Linux/Debug/Minecraft.Client

Clean

make clean

To fully reset the CMake configuration (removes cache + generated Makefiles):

rm -rf CMakeCache.txt CMakeFiles cmake_install.cmake Makefile
# Then re-run: cmake . && make -j$(nproc)

Running

# Default — window opens at your primary monitor's native resolution (windowed)
./Linux/Debug/Minecraft.Client

(todo refactor)
