# Building

The repository contains everything required to compile and build the examples on Windows, Linux and Android using a C++ compiler that supports C++11. All required dependencies are included.

## <img src="./images/windowslogo.png" alt="" height="32px"> Windows
Use the provided CMakeLists.txt with [CMake](https://cmake.org) to generate a build configuration for your favorite IDE or compiler, e.g.:

```
cmake -G "Visual Studio 16 2019" -A x64
```

## <img src="./images/linuxlogo.png" alt="" height="32px"> Linux

Use the provided CMakeLists.txt with [CMake](https://cmake.org) to generate a build configuration for your favorite IDE or compiler.

##### [Window system integration](https://www.khronos.org/registry/vulkan/specs/1.0-wsi_extensions/html/vkspec.html#wsi)
- **XCB**: Default WSI (if no cmake option is specified)
- **Wayland**: Use cmake option ```USE_WAYLAND_WSI``` (```-DUSE_WAYLAND_WSI=ON```)
- **DirectFB**: Use cmake option ```USE_DIRECTFB_WSI``` (```-DUSE_DIRECTFB_WSI=ON```)
- **DirectToDisplay**: Use cmake option ```USE_D2D_WSI``` (```-DUSE_D2D_WSI=ON```)

Building on Android is done using the [Gradle Build Tool](https://gradle.org/):

If you want to build it through command line, set Android SDK/NDK by environment variable `ANDROID_SDK_ROOT`/`ANDROID_NDK_HOME`.

On Linux execute:

```
cd android
./gradlew assembleDebug
```
This will download gradle locally, build all samples and output the apks to ```android/examples/bin```.

On Windows execute ```gradlew.bat assembleDebug```.

If you want to build and install on a connected device or emulator image, run ```gradle installDebug``` instead.

If you want to build it through [Android Studio](https://developer.android.com/studio), open project folder ```android``` in Android Studio.

Building for *iOS* and *macOS* is done using the [examples](xcode/examples.xcodeproj) *Xcode* project found in the [xcode](xcode) directory. These examples use the [**MoltenVK**](https://moltengl.com/moltenvk) Vulkan driver to provide Vulkan support on *iOS* and *macOS*, and require an *iOS* or *macOS* device that supports *Metal*. Please see the [MoltenVK Examples readme](xcode/README_MoltenVK_Examples.md) for more info on acquiring **MoltenVK** and building and deploying the examples on *iOS* and *macOS*.

##### MacOS
Use the provided CMakeLists.txt with [CMake](https://cmake.org) to generate a build configuration for your favorite IDE or compiler, e.g.:
```
cmake -G "Xcode"
```
