Gainput has very few external dependencies in order to make it as self-contained as possible. Normally, the only extra piece of software you might have to install is CMake. Anything else should come with your IDE (or regular platform SDK).

Libraries

Most importantly, Gainput does not depend on the STL or any other unnecessary helper libraries. Input is acquired using the following methods:

Android NDK: All input is acquired through the NDK. Native App Glue is used for most inputs.

iOS:

• CoreMotion framework for built-in device sensors
• GameController framework for gamepad inputs
• UIKit for touch inputs

Linux:

• the X11 message loop is used for keyboard and mouse
• the kernel's joystick API is used for pads

Mac OS X:

• AppKit for mouse
• IOKit's IOHIDManager for keyboard and gamepads

Windows:

• the Win32 message loop is used for keyboard and mouse
• XINPUT is used for gamepads

Building

Gainput is built using CMake
