In order to build SuperTuxKart from source, you'll need both the code and the assets (See <https://supertuxkart.net/Source_control> for more information):
STK can then be run from the build directory with `bin/supertuxkart`
#### Keeping your build up to date
To recompile the latest code without redownloading the entire source, first run the ```svn up``` command inside the 'stk-assets' directory, then run the following commands inside the 'stk-code' directory:
To Build SuperTuxKart on Windows, first you need to install [Python](https://www.python.org/downloads/windows/) for [shaderc](https://github.com/google/shaderc) used by SuperTuxKart, after installing Python (if needed) follow these instructions:
1. Download and install Visual Studio from here: [Visual Studio - Download](https://www.visualstudio.com/downloads/). The free Visual Studio Community edition works fine. Remember to select "Desktop development with C++" in the installer.
2. If you want the stable version, download the SuperTuxKart source package from the latest stable version [SuperTuxKart on GitHub](https://github.com/supertuxkart/stk-code/releases) and unpack it.
3. If you want the development version, you will need a Git client and a SVN client. More information can be found here: [SuperTuxKart.net - Source Control](https://supertuxkart.net/Source_control).
Open your file browser and find somewhere you want to put the development version of SuperTuxKart. For example in C:\Users\<Your Username> as the Git and SVN clients will have write permissions there, and you should create its own directory, for example SuperTuxKart-dev. Enter that directory, and create a directory inside called stk-assets, and enter it. If you installed TortoiseSVN, right-click, select TortoiseSVN -> Checkout... and paste the corresponding URL found in [SuperTuxKart.net - Source Control](https://supertuxkart.net/Source_control). While it is downloading the game assets, go back to your file browser and one level up. Right-click again somewhere empty and select "Git clone..." and paste the corresponding link found in [SuperTuxKart.net - Source Control](https://supertuxkart.net/Source_control).
4. If you got the stable version, download the Windows dependencies package from [SuperTuxKart on GitHub - Dependencies Releases](https://github.com/supertuxkart/dependencies/releases), find the stk-code version there and download the `dependencies(arch).zip` as needed and unpack the archive into the `stk-code` directory.
5. If you got the development version go to SuperTuxKart-dev in your file browser, then visit [SuperTuxKart on GitHub - Dependencies latest preview release](https://github.com/supertuxkart/dependencies/releases/tag/preview)
and unpack the archive into the `stk-code` directory. Download `i686` if you use Win32 generator of MSVC, `x86_64` for x64 and `aarch64` for ARM64.
6. Download CMake from here: [CMake - download page](https://cmake.org/download/), install it; once CMake is installed, double click on the CMake icon on your desktop, and point it towards your `stk-code` directory in the 'Where is the source code' field, and point 'Where to build the binaries' to a new directory called `build` or `bld` inside the stk-code directory.
7. Press 'Configure'; CMake will ask you if it is OK to create the aforementioned directory, press `Yes`. CMake will then ask you about your version of Visual Studio.
Confirm your selection; *Please look at the table below to avoid confusion between version numbers and releases of Visual Studio*; CMake will begin creating the required files for the build in the directory. If you want to do a 64-bit build, select the version of Visual Studio you installed with "Win64" appended. Press 'Generate' button.
1. Download and install Visual Studio from here: [Visual Studio - Download](https://www.visualstudio.com/downloads/), the free Visual Studio Community edition works fine.
2. Download a source package from either [SuperTuxKart on GitHub](https://github.com/supertuxkart/stk-code/releases) or [SuperTuxKart.net - Source Control](https://supertuxkart.net/Source_control)
NOTE: the `stk-code` and `stk-assets` directories **must** be in the same directory, `stk-assets` is not needed if you download the full source tarball `(SuperTuxKart-version-src.tar.xz)`.
3. Download the Windows dependencies package from [SuperTuxKart on GitHub - Dependencies latest preview release](https://github.com/supertuxkart/dependencies/releases/tag/preview)
and unpack the archive into the `stk-code` directory. Download `i686` if you use Win32 generator of MSVC, `x86_64` for x64 and `aarch64` for ARM64.
4. Download CMake from here: [CMake - download page](https://cmake.org/download/); and install it. Navigate to the `stk-code` directory; and create an directory called "build":
## Building SuperTuxKart on Windows using LLVM MinGW
1. Get the LLVM Mingw archive [here](https://github.com/mstorsjo/llvm-mingw/releases/latest), get the `*-msvcrt-i686.zip or``*-msvcrt-x86_64.zip` depending on whether you have an Intel / AMD 32 or 64-bit Windows. If you are using ARM64 Windows get the `*-msvcrt-i686.zip` should be fine (untested). After downloading extract it as `C:\llvm-mingw` so `C:\llvm-mingw` contains `bin`, `include`, `lib`, etc.
2. Get Ninja [here](https://github.com/ninja-build/ninja/releases/latest), download the `ninja-win.zip` and extract the `ninja.exe` from the archive to `C:\llvm-mingw`. If you are not using Intel / AMD 64-bit Windows use [this link](https://packages.msys2.org/package/mingw-w64-i686-ninja) and extract `mingw32\bin\ninja.exe` inside the `tar.zst`.
3. Download a source package from either [SuperTuxKart on GitHub](https://github.com/supertuxkart/stk-code/releases) or [SuperTuxKart.net - Source Control](https://supertuxkart.net/Source_control)
NOTE: the `stk-code` and `stk-assets` directories **must** be in the same directory, `stk-assets` is not needed if you download the full source tarball `(SuperTuxKart-version-src.tar.xz)`. Also make sure they lie within the C drive.
4. Download the Windows dependencies package from [SuperTuxKart on GitHub - Dependencies latest preview release](https://github.com/supertuxkart/dependencies/releases/tag/preview)
and unpack the archive into the `stk-code` directory. Download `i686` if you compile for Intel / AMD 32-bit Windows, `x86_64` for Intel / AMD 64-bit Windows and `aarch64` for ARM64 Windows.
6. Download CMake from here: [CMake - download page](https://cmake.org/download/), install it; once CMake is installed, double click on the CMake icon on your desktop, and point it towards your `stk-code` directory in the 'Where is the source code' field, and point 'Where to build the binaries' to a new directory called `build` inside the stk-code directory.
7. Press the `Add Entry` button and add the values below:
* Name: `LLVM_ARCH` Type: `STRING` Value: `i686`, `x86_64` or `aarch64`
8. Press 'Configure'; CMake will ask you if it is OK to create the aforementioned directory, press `Yes`. Choose `Ninja` from `Specify the generator for this project`, choose `Specify toolchain file for cross-compiling` then press `Next`. Specify the toolchain file which is located in `stk-code\cmake\Toolchain-llvm-mingw.cmake` and press `Finish`. If no error appears then press 'Generate'
9. Once inside the build directory using command line `cmd.exe` or PowerShell:
```cmd
C:\llvm-mingw\ninja.exe
```
SuperTuxKart can now be run as `bin\supertuxkart.exe`.
Download `dependencies-macosx.tar.xz` from `Assets` section [here](https://github.com/supertuxkart/dependencies/releases) and extract it inside stk-code directory, use `preview` version for git stk-code.
