# Antkeeper Superbuild

This repository contains the superbuild system and all dependencies required to build Antkeeper.

## Download

Download the Antkeeper superbuild repository and all of its Git submodules:

	git clone --recursive https://git.antkeeper.com/antkeeper/superbuild.git

> Note: The `antkeeper-data` submodule contains proprietary game data and is not publicly available. The game can be built without this submodule, but the game data is required to play Antkeeper. You can get a copy of the game data by purchasing Antkeeper at [antkeeper.com](https://antkeeper.com/).

## Configuration & Building

CMake is required to configure and build the application. Depending on the target platform, CMake should be invoked from one of the following directories:

| Directory                      | Platform       |
| :----------------------------- | :------------- |
| [build/linux32](build/linux32) | 32-bit Linux   |
| [build/linux64](build/linux64) | 64-bit Linux   |
| [build\win32](build/win32)     | 32-bit Windows |
| [build\win64](build/win64)     | 64-bit Windows |

The following arguments may be passed to CMake during configuration:

	-DCMAKE_BUILD_TYPE // [Debug, Release]

### Linux

Building for Linux requires CMake, GCC, G++, and GNU Make. Navigate to either the [build/linux32](build/linux32) or [build/linux64](build/linux64) directory and run the following commands:

	cmake ../.. -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=...
	cmake --build .

### Windows

Building for Windows requires CMake and Visual Studio Build Tools. Additionally, [NSIS](http://nsis.sourceforge.net/) is required if you want to build a distributable installer program. In order to correctly build for your target architecture, you must use the `x86 Native Tools Command Prompt` or the `x64 Native Tools Command Prompt` for 32-bit and 64-bit applications, respectively. Then navigate to either the [build\win32](build/win32) or [build\win64](build/win64) directory and run the following commands:

	cmake ..\.. -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=...
	cmake --build .

## Running

After building, a standalone version of the application will be located somewhere in the `bin` directory according to the build type, build platform, and version string.

## Distribution

The built application can be packaged into a distributable format with the following command:

	cmake --build . --target dist

The resulting package will be located in the `dist` directory.

## Contributing

If any changes have been made to the submodules, commit those first. Each submodule can then be updated to their latest commits with the following command:

	git submodule update --recursive --remote
