Linux
The Linux versions are developed on Gentoo and use the following dynamic libraries that should be present on your system:
X Server with XInput 2 extension (libX11, libXi)
Graphics rendering via GLX with OpenGL 1.2 (libGL), or EGL with OpenGL ES 1.0 (libEGL, libGLESv1_CM)
libpng (libpng16)
ALSA (libasound)
Minizip, from zlib (libminizip)
BlueZ (libbluetooth)
Freetype (libfreetype)
Fontconfig (libfontconfig)
DBUS (libdbus-1)
GLIBC 2.8+
some apps use the C++ runtime from GCC 4.8+ (libstdc++)
OS-specific Features:
Drag & Drop: Drag a directory into the window to open a file menu at that location, or drag a supported file type to open it.
Multi-pointer: Supports multiple master mouse pointers that interact with the app simultaneously, mainly used to test the on-screen controller
Full-screen: Push alt-enter to toggle, does not change your existing screen mode
DBUS: Runs as a single instance and accepts certain DBUS commands to load directories and files (see source)
Logging: Debug versions print to stdout, use this to check for any errors if the non-debug versions don't work
