Getting Started

MaSzyna compiles and runs natively on Linux and Windows. Other platforms are not tested.

Heads-up
Our dev team is small; we keep improving the build process, but issues may still occur. If you get stuck, please ask on the official Discord server.

Prerequisites

For runtime requirements see Minimum Requirements.

1) Software (oldest tested in parentheses)

• CMake (3.0)

• make

• A C++ compiler with C++20 support:

  • Windows: Visual Studio 2022

  • Linux: GCC (12.3.1)

Note: MinGW is currently not supported.

2) Libraries (oldest tested in parentheses)

• GLFW 3.x (3.2.1)
  If a link error occurs, pass -DGLFW3_LIBRARIES="<path>" to CMake.

• GLM (0.9.9.0)

• libserialport (0.1.1)

• libsndfile (1.0.28)

• LuaJIT (2.0.5)

• GLEW (2.1.0)

• libpng (1.6.34)

• OpenAL (1.18.2)

• pthread

• Python 3.14 (64-bit; headers and import library required for embedding)

• Asio (1.12)

3) Graphics API

• OpenGL 3.0 or newer
• DirectX 12 via NVRHI (optional, Windows only, for Better Renderer)

CMake flags

Flag	Meaning
-DCMAKE_BUILD_TYPE=Debug	Debug build
-DCMAKE_BUILD_TYPE=Release	Release build
-DCMAKE_BUILD_TYPE=RelWithDebInfo	Release build with debug symbols
-DWITH_BETTER_RENDERER=ON/OFF	Enable/disable NVRHI-based renderer
-DPython3_ROOT_DIR=<path>	Root of the Python 3.14 install on Windows (python.exe, Lib, DLLs) for embed/copy steps; on Linux, optional if CMake picks the wrong interpreter

Linux note: WITH_BETTER_RENDERER uses DirectX 12 through NVRHI and is not supported on Linux.

Windows

Install Python 3.14 x64 from python.org and include the optional Python native development feature (headers and .lib for embedding). Pass -DPython3_ROOT_DIR="C:\Path\To\Python314" on the cmake line when you want the layout under that directory used for embedding and for copying Lib / DLLs next to the executable.

AppVeyor CI builds with the worker image’s preinstalled Python at C:/Python314-x64 (see appveyor.yml: -DPython3_ROOT_DIR=...).

# Clone repository with submodules
git clone --recursive https://github.com/MaSzyna-EU07/maszyna.git

cd maszyna

# Init vcpkg
call setup.bat

# Create directory for CMake build files
mkdir build
cd build

# Generate CMake project (replace %CONFIG% with Debug/Release/RelWithDebInfo)
cmake .. -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=%CONFIG%

# Build (replace %CONFIG% accordingly)
cmake --build . --config %CONFIG% --parallel

# Install dependencies (Fedora/RHEL family)
sudo dnf install -y \

# Clone repository with submodules

cd maszyna

# Create directory for CMake build files

# Generate Makefiles (NVRHI is not supported on Linux)

# Compile using all cores
make -j"$(nproc)"

Tip (Ubuntu/Debian): Package names differ; install equivalent build-essential, libgl1-mesa-dev, libglew-dev, libglfw3-dev, python3.14-dev, libpng-dev, libopenal-dev, libluajit-5.1-dev, libserialport-dev, libsndfile1-dev, and Wayland/X11 dev packages as needed.

Installing

There is no make install yet. Copy the built executable to your MaSzyna installation manually.

• Output directory: ./bin

• File name format: eu07_YYYY-MM-DD_<commit>[_d]

  • YYYY-MM-DD – build date

  • <commit> – short commit hash

  • _d – present in Debug builds

If you already have the MaSzyna assets, copy the executable to the install dir. Assets can be downloaded from eu07.pl.

Rainsted on Linux

If Rainsted (a third‑party starter) fails to detect the executable under Linux, you can create a small wrapper script named eu07.exe:

#!/bin/sh
./eu07 "$1" "$2" "$3" "$4" "$5"

If detection still fails, padding the file (with comments) up to ~1 MB may help.

Known Issues

• GLFW linking – On some systems you must provide the GLFW library path explicitly with -DGLFW3_LIBRARIES.

• X11/Wayland linking order – Linking order of X11 and related libs can matter.

• NVRHI on Linux – The NVRHI/"Better Renderer" path targets DirectX 12 and is currently unsupported on Linux.
