# Building McRogueFace from Source
This document describes how to build McRogueFace from a fresh clone.
## Build Options
There are two ways to build McRogueFace:
1. **Quick Build** (recommended): Use pre-built dependency libraries from a `build_deps` archive
2. **Full Build**: Compile all dependencies from submodules
## Prerequisites
### System Dependencies
Install these packages before building:
```bash
# Debian/Ubuntu
sudo apt install \
build-essential \
cmake \
git \
zlib1g-dev \
libx11-dev \
libxrandr-dev \
libxcursor-dev \
libfreetype-dev \
libudev-dev \
libvorbis-dev \
libflac-dev \
libgl-dev \
libopenal-dev
```
**Note:** SDL is NOT required - McRogueFace uses libtcod-headless which has no SDL dependency.
---
## Option 1: Quick Build (Using Pre-built Dependencies)
If you have a `build_deps.tar.gz` or `build_deps.zip` archive:
```bash
# Clone McRogueFace (no submodules needed)
git clone <repository-url> McRogueFace
cd McRogueFace
# Extract pre-built dependencies
tar -xzf /path/to/build_deps.tar.gz
# Or for zip: unzip /path/to/build_deps.zip
# Build McRogueFace
mkdir -p build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
# Run
./mcrogueface
```
The `build_deps` archive contains:
- `__lib/` - Pre-built shared libraries (Python, SFML, libtcod-headless)
- `deps/` - Header symlinks for compilation
**Total build time: ~30 seconds**
---
## Option 2: Full Build (Compiling All Dependencies)
### 1. Clone with Submodules
```bash
git clone --recursive <repository-url> McRogueFace
cd McRogueFace
```
If submodules weren't cloned:
```bash
git submodule update --init --recursive
```
**Note:** imgui/imgui-sfml submodules may fail - this is fine, they're not used.
### 2. Create Dependency Symlinks
```bash
cd deps
ln -sf ../modules/cpython cpython
ln -sf ../modules/libtcod-headless/src/libtcod libtcod
ln -sf ../modules/cpython/Include Python
ln -sf ../modules/SFML/include/SFML SFML
cd ..
```
### 3. Build libtcod-headless
libtcod-headless is our SDL-free fork with vendored dependencies:
```bash
cd modules/libtcod-headless
mkdir build && cd build
cmake .. \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS=ON
make -j$(nproc)
cd ../../..
```
That's it! No special flags needed - libtcod-headless defaults to:
- `LIBTCOD_SDL3=disable` (no SDL dependency)
- Vendored lodepng, utf8proc, stb
### 4. Build Python 3.12
```bash
cd modules/cpython
./configure --enable-shared
make -j$(nproc)
cd ../..
```
### 5. Build SFML 2.6
```bash
cd modules/SFML
mkdir build && cd build
cmake .. \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS=ON
make -j$(nproc)
cd ../../..
```
### 6. Copy Libraries
```bash
mkdir -p __lib
# Python
cp modules/cpython/libpython3.12.so* __lib/
# SFML
cp modules/SFML/build/lib/libsfml-*.so* __lib/
# libtcod-headless
cp modules/libtcod-headless/build/bin/libtcod.so* __lib/
# Python standard library
cp -r modules/cpython/Lib __lib/Python
```
### 7. Build McRogueFace
```bash
mkdir -p build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
```
### 8. Run
```bash
./mcrogueface
```

## Submodule Versions
| Submodule | Version | Notes |
|-----------|---------|-------|
| SFML | 2.6.1 | Graphics, audio, windowing |
| cpython | 3.12.2 | Embedded Python interpreter |
| libtcod-headless | 2.2.1 | SDL-free fork for FOV, pathfinding |
---
## Creating a build_deps Archive
To create a `build_deps` archive for distribution:
```bash
cd McRogueFace
# Create archive directory
mkdir -p build_deps_staging
# Copy libraries
cp -r __lib build_deps_staging/
# Copy/create deps symlinks as actual directories with only needed headers
mkdir -p build_deps_staging/deps
cp -rL deps/libtcod build_deps_staging/deps/ # Follow symlink
cp -rL deps/Python build_deps_staging/deps/
cp -rL deps/SFML build_deps_staging/deps/
cp -r deps/platform build_deps_staging/deps/
# Create archives
cd build_deps_staging
tar -czf ../build_deps.tar.gz __lib deps
zip -r ../build_deps.zip __lib deps
cd ..
# Cleanup
rm -rf build_deps_staging
```
The resulting archive can be distributed alongside releases for users who want to build McRogueFace without compiling dependencies.
**Archive contents:**
```
build_deps.tar.gz
├── __lib/
│ ├── libpython3.12.so*
│ ├── libsfml-*.so*
│ ├── libtcod.so*
│ └── Python/ # Python standard library
└── deps/
├── libtcod/ # libtcod headers
├── Python/ # Python headers
├── SFML/ # SFML headers
└── platform/ # Platform-specific configs
```
---
## Verify the Build
```bash
cd build
# Check version
./mcrogueface --version
# Test headless mode
./mcrogueface --headless -c "import mcrfpy; print('Success')"
# Verify no SDL dependencies
ldd mcrogueface | grep -i sdl # Should output nothing
```
---
## Troubleshooting
### OpenAL not found
```bash
sudo apt install libopenal-dev
```
### FreeType not found
```bash
sudo apt install libfreetype-dev
```
### X11/Xrandr not found
```bash
sudo apt install libx11-dev libxrandr-dev
```
### Python standard library missing
Ensure `__lib/Python` contains the standard library:
```bash
ls __lib/Python/os.py # Should exist
```
### libtcod symbols not found
Ensure libtcod.so is in `__lib/` with correct version:
```bash
ls -la __lib/libtcod.so*
# Should show libtcod.so -> libtcod.so.2 -> libtcod.so.2.2.1
```
---
## Build Times (approximate)
On a typical 4-core system:
| Component | Time |
|-----------|------|
| libtcod-headless | ~30 seconds |
| Python 3.12 | ~3-5 minutes |
| SFML 2.6 | ~1 minute |
| McRogueFace | ~30 seconds |
| **Full build total** | **~5-7 minutes** |
| **Quick build (pre-built deps)** | **~30 seconds** |
---
## Runtime Dependencies
The built executable requires these system libraries:
- `libz.so.1` (zlib)
- `libopenal.so.1` (OpenAL)
- `libX11.so.6`, `libXrandr.so.2` (X11)
- `libfreetype.so.6` (FreeType)
- `libGL.so.1` (OpenGL)
All other dependencies (Python, SFML, libtcod) are bundled in `lib/`.

## Building from Source
For most users, pre-built releases are available. If you need to build from source:
### Quick Build (with pre-built dependencies)
Download `build_deps.tar.gz` from the releases page, then:
```bash
git clone <repository-url> McRogueFace
cd McRogueFace
tar -xzf /path/to/build_deps.tar.gz
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
```
### Full Build (compiling all dependencies)
```bash
git clone --recursive <repository-url> McRogueFace
cd McRogueFace
# See BUILD_FROM_SOURCE.md for complete instructions
```
