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:
```bash
git pull
cd cmake_build
cmake ..
make -j4
```
##### Build Speed Optimization
"-j4" is an example, for a faster build, use "-jx" instead, where "x" is the amount of CPU threads you have, minus one. "-j$(nproc)" usually works.
### Further options
To create a debug version of STK, run:
```bash
cmake .. -DCMAKE_BUILD_TYPE=Debug
```
You can install your build system-wide:
```bash
sudo make install
```
The default install location is `/usr/local`, i.e. the data files will
be written to `/usr/local/share/games/supertuxkart`, the executable
will be copied to `/usr/local/bin`. To change the default installation
location, specify `CMAKE_INSTALL_PREFIX` when running cmake, e.g.:
`cmake .. -DCMAKE_INSTALL_PREFIX=/opt/stk`
## Building SuperTuxKart on Windows
To Build SuperTuxKart on Windows, 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.
2a. If you want the stable version, download the SuperTuxKart source package from the latest stable version [SuperTuxKart download area - SourceForge.net](https://sourceforge.net/projects/supertuxkart/files/SuperTuxKart/) and unpack it.
2b. 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 correspodning 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).
*Note: Both `stk-code` and `stk-assets`**must** be in the same directory, otherwise the build will likely fail!*
3a. If you got the stable version, download the Windows dependencies package from [SuperTuxKart download area: Dependencies - SourceForge.net](https://sourceforge.net/projects/supertuxkart/files/SuperTuxKart%20Dependencies/Windows/) and unpack it.
3b. If you got the development version go to SuperTuxKart-dev in your file browser, right-click somewhere empty, select "Git clone..." and paste https://github.com/supertuxkart/dependencies.git in the URL field; click OK. When finished, copy the `dependencies` directory from either the `windows` or the `windows_64bit` directories into the `stk-code` directory; rename the latter to `dependencies-64bit` if you want to compile a 64-bit build.
4. 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 it to a new directory called `build` or `bld` inside the stk-code directory.
5. 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.
8. Open the 'Build' menu and select 'Build Solution'; or, press the default keyboard shortcut: `CTRL + SHIFT + B` to build the solution.
*Note: To avoid confusion between releases and versions, refer to this table:*
Visual Studio Release | Version
----------------------|------------
Visual Studio 2017| 15
Visual Studio 2015| 14
Visual Studio 2013| 13
## Building SuperTuxKart on Windows (from PowerShell/Command line)
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 0.9.2 download area - SourceForge.net](https://sourceforge.net/projects/supertuxkart/files/SuperTuxKart/0.9.2) or [SuperTuxKart.net - Source Control](https://supertuxkart.net/Source_control)
NOTE: the `stk-code` and `stk-assets` directories **must** be in the same directory
3. Download the Windows dependencies package from either [SuperTuxKart download area - SourceForge.net](https://sourceforge.net/projects/supertuxkart/files/SuperTuxKart%20Dependencies/Windows/)
or [SuperTuxKart on GitHub - Dependencies](https://github.com/supertuxkart/dependencies)
and unpack the archive; once unpacked, copy the `dependencies` directory from either the `windows` or the `windows_64bit` directories into the `stk-code` directory
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":
```cmd
mkdir build
cd build
```
5. Once inside the build directory; run CMake to start the compilation process:
```cmd
cmake ..
```
6. Now that CMake finished configuring and creating the necessary files for the build, run the build command in the same directory:
```cmd
msbuild.exe SuperTuxKart.sln
```
SuperTuxKart can now be run as `bin\Debug\supertuxkart.exe` or `bin\Release\supertuxkart.exe`
## Building SuperTuxKart on macOS
### Getting Started
Install the developer tools, either from the OS X Install DVD or from Apple's website.
If you have never built anything before, you have create `/usr/local/include/` first:
```bash
sudo mkdir -p /usr/local/include/
```
Symlink the `include`-folder of OpenGL framework to `/usr/local/include/GL` (Unix programs have an easier time finding it this way):
Download pre-built dependencies from [here](https://sourceforge.net/projects/supertuxkart/files/SuperTuxKart%20Dependencies/OSX/) and put the frameworks in [hard disk root]/Library/Frameworks
