Fixed bug 3138 - c_dfDIJoystick2 already defined in dinput8.lib Machiel van Hooren In SDL_dxjoystick.c line 349 there is a constant c_dfDIJoystick2. However, this constant is aparently also defined in dinput8.lib. I encountered a linking error when statically linking to SDL: SDL2_static.lib(SDL_dxjoystick.obj) : error LNK2005: _c_dfDIJoystick2 already defined in dinput8.lib My application is also linking to dinput8.lib because we rolled our own joystick input and are not using the joystick functionality from SDL.
