2 Building AnKi

Build Status Linux Build Status Windows Build Status Android

To checkout the source type:

git clone https://github.com/godlikepanos/anki-3d-engine.git anki

AnKi's build system is using CMake. A great effort was made to ease the building process that's why the number of external dependencies are almost none.

2.1 On Linux

Prerequisites:

  • Cmake 3.10 and up
  • GCC 5.0 and up or Clang 6.0 and up
  • libx11-dev installed
  • libxrandr-dev installed
  • libx11-xcb-dev installed
  • [Optional] libxinerama-dev if you want proper multi-monitor support

To build the release version:

$cd path/to/anki
$mkdir build
$cd ./build
$cmake .. -DCMAKE_BUILD_TYPE=Release
$make

To view and configure the build options you can use ccmake tool or other similar tool:

$cd path/to/anki/build
$ccmake .

This will open an interface with all the available options.

2.2 On Windows

Prerequisites:

  • Cmake 3.10 and up
  • Python 3.0 and up
    • Make sure that the python executable's location is in PATH environment variable
  • Microsoft Visual Studio 2017 and up
    • Make sure that Windows 10 SDK (xxx) for Desktop C++ [x86 and x64] component is installed

To build the release version open PowerShell and type:

$cd path/to/anki
$mkdir build
$cd build
$cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release
$cmake --build . --config Release

Alternatively, recent Visual Studio versions support building CMake projects from inside the IDE:

  • Open Visual Studio
  • Choose the "open a local folder" option and open AnKi's root directory (where this README.md is located)
  • Visual Studio will automatically understand that AnKi is a CMake project and it will populate the CMake cache
  • Press "build all"

2.3 For Android

Prerequisites:

  • Android Studio
  • From Android Studio's package manager you need to install NDK and CMake
  • Having built AnKi for your host operating system (Linux or Windows)

Android builds work a bit differently from Linux and Windows. First you need to have built AnKi for your host operating system. That's because Android builds requires the ShaderCompiler/ShaderCompiler.exe to compile the shaders for Android. Then you have to generate a gradle project per build target.

For example, if you want to generate a project for the Sponza sample just type from a Linux terminal:

$cd path/to/anki
$./Samples/Sponza/GenerateAndroidProject.sh path/to/Bin/ShaderCompiler

or from a PowerShell terminal on Windows:

$cd path/to/anki
$./Samples/Sponza/GenerateAndroidProject.bat path/to/Bin/ShaderCompiler.exe

The GenerateAndroidProject scripts will generate a project in the root directory of AnKi. So for the Sponza sample the script will create a directory named AndroidProject_Sponza.

Then you can open the AndroidProject_Sponza project from Android Studio and build it, debug it, run it etc.

3 Next steps

This code repository contains 4 sample projects that are built by default (ANKI_BUILD_SAMPLES CMake option):

  • Sponza: The Crytek's Sponza scene
  • SimpleScene: A simple scene (Cornell box)
  • PhysicsPlayground: A scene with programmer's art and some physics interactions
  • SkeletalAnimation: A simple scene with an animated skin

You can try running them and interacting with them. To run sponza, for example, execute the binary from any working directory.

On Linux:

$./path/to/build/Bin/Sponza

On Windows just find the Sponza.exe and execute it. It's preferable to run the samples from a terminal because that prints some information, including possible errors.
