# Building Motherload

This repository now supports both the original Visual Studio solution files and a CMake-based build.

## Supported build paths

### 1. CMake on Windows
Recommended if you want a modern, editor-friendly build setup.

Requirements:
- Visual Studio 2022 with Desktop development with C++
- CMake 3.21+

The repository already contains the required prebuilt Windows SDL packages in `Libraries/`.

Configure and build:

```bash
cmake -S . -B build -G "Visual Studio 17 2022" -A x64
cmake --build build --config Debug
```

### 2. CMake on Linux
Requirements:
- C++ compiler
- CMake 3.21+
- SDL2 development packages
- OpenGL development package

Ubuntu / Debian example:

```bash
sudo apt install build-essential cmake libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev libgl1-mesa-dev
cmake -S . -B build
cmake --build build
```

### 3. Legacy Visual Studio solution
The existing `.sln` and `.vcxproj` files are still in the repo and can still be opened directly in Visual Studio.

## Build output

The CMake build writes the executable to:
- `build/bin/` for single-config generators
- the active configuration output folder for Visual Studio generators

Resource files from `Resources/` are copied automatically after a successful build.

## Notes about dependencies

### Windows
CMake uses the bundled SDL package config files from:
- `Libraries/SDLMain/.../cmake`
- `Libraries/SDLImage/.../cmake`
- `Libraries/SDLMixer/.../cmake`
- `Libraries/SDLTtf/.../cmake`

### Linux
CMake falls back to `pkg-config` and expects these packages to be installed:
- `sdl2`
- `SDL2_image`
- `SDL2_mixer`
- `SDL2_ttf`

## Troubleshooting

### CMake fails at `find_package(OpenGL REQUIRED)`
Install the OpenGL development package.

Ubuntu / Debian:

```bash
sudo apt install libgl1-mesa-dev
```

### CMake cannot find SDL packages on Linux
Install the SDL development packages listed above.

### The game starts but cannot find assets
Run the executable from the build output directory, not from the source directory root. The post-build step copies `Resources/` next to the executable.

### Why are the old MSVC `#pragma comment(lib, ...)` lines still in the code?
They are still there for the legacy Visual Studio project files, but the CMake build disables them explicitly so dependency management stays inside CMake.
