MaSzyna executable source code is licensed under the [MPL 2.0](https://www.mozilla.org/en-US/MPL/2.0/) and comes with a large pack of free assets under a [custom license](https://eu07.pl/docs/inne/readme_pliki/en-licence.html).

## 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](https://discord.gg/qAh9ctWPQv).
### Prerequisites
> For runtime requirements see [Minimum Requirements](#minimum-requirements).
**1) Software** _(oldest tested in parentheses)_
- [CMake](https://cmake.org/) _(3.0)_
- [make](https://www.gnu.org/software/make/)
- A C++ compiler with C++14 support (we use some C++17 features, but older compilers may still work):
- **Windows:** Visual Studio 2022
- **Linux:** GCC _(12.3.1)_
> **Note:** MinGW is currently **not supported**.
**2) Libraries** _(oldest tested in parentheses)_
- [GLFW 3.x](https://www.glfw.org/) _(3.2.1)_
If a link error occurs, pass `-DGLFW3_LIBRARIES="<path>"` to CMake.
- [GLM](https://glm.g-truc.net/) _(0.9.9.0)_
- [libserialport](https://sigrok.org/wiki/Libserialport) _(0.1.1)_
- [libsndfile](https://github.com/erikd/libsndfile) _(1.0.28)_
- [LuaJIT](http://luajit.org/) _(2.0.5)_
- [GLEW](http://glew.sourceforge.net/) _(2.1.0)_
- [libpng](http://www.libpng.org/pub/png/libpng.html) _(1.6.34)_
- [OpenAL](https://www.openal.org/) _(1.18.2)_
- **pthread**
- [Python 3.14](https://www.python.org/) _(64-bit; headers and import library required for embedding)_
- [Asio](https://think-async.com/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 directory of the **Python 3.14** install to use (embedding); needed if several versions are present |
> **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](https://www.python.org/downloads/windows/) and include the optional **Python native development** feature (headers and `.lib` for embedding). If CMake picks another interpreter, pass `-DPython3_ROOT_DIR="C:\Path\To\Python314"` on the `cmake` line.
**AppVeyor CI** builds with the worker images preinstalled Python at `C:/Python314-x64` (see [`appveyor.yml`](./appveyor.yml): `-DPython3_ROOT_DIR=...` and `-DWITH_PYTHON_AUTO_INSTALL_WIN=OFF`).
```powershell
# 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
```

```
> **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](https://eu07.pl/).
**Rainsted on Linux**
If `Rainsted` (a thirdparty starter) fails to detect the executable under Linux, you can create a small wrapper script named `eu07.exe`:
```sh
#!/bin/sh
./eu07 "$1" "$2" "$3" "$4" "$5"
```
If detection still fails, padding the file (with comments) up to ~1MB 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.
## Support
- **Issues:** [https://github.com/MaSzyna-EU07/maszyna/issues](https://github.com/MaSzyna-EU07/maszyna/issues)
- **Official Discord Server:** [https://discord.gg/qAh9ctWPQv](https://discord.gg/qAh9ctWPQv)
- **Project page:** [https://eu07.pl/](https://eu07.pl/)
## Minimum requirements
- OS: **Windows 10 64-bit**
- Processor: **2 core at least 2 GHz (e.g. Intel Core i3-2100 / AMD Athlon II X2)**
- RAM: **6 GB RAM**
- Graphics Card: **supporting OpenGL 3.3 with at least 1GB VRAM**
- **150 GB of free disk space**
- Sound card supporting OpenAL with stereo
- Optional COM ports for custom control panel setups.
