# YoYo Compiler
The YoYo Compiler (YYC) is a special compiler for creating executable packages that use machine code instead of interpreted code and a runner (which is what the GameMaker VM compile uses). Compiled code is faster to run, but takes more time to compile the executable.
## Setting Up The SDK
In order for the YoYo Compiler to be able to compile for the target platform, you will need to have the correct SDKs installed.
For a general overview on this, see the following Help Center page: [GameMaker Required SDKs](https://help.gamemaker.io/hc/en-us/articles/227860547-GameMaker-Required-SDKs).
Information on the SDKs required per platform can be found in the Help Center as well:

## Building a project with YYC
Once you have the SDKs set up correctly you can change the Output option for the selected platform to YYC:
In case the current runtime doesn't include the YYC module for the platform you want to build for you will be asked to install it first:
After that you can create the executable from [The Build Menu](../IDE_Navigation/Menus/The_Build_Menu.md) as with the VM output.
If the path to the SDK wasn't configured correctly you may get an error like the following (the image shows the message on the Windows platform):
GameMaker needs to know the location of the files needed to build an executable on the selected platform. In case this hasn't been set up correctly, a compile error is shown.
To verify that the paths have been set correctly for the selected platform, you can check the [Platform Preferences](../Setting_Up_And_Version_Information/Platform_Preferences.md).
