A compilation error occurs when visualboyadvance try to compile with media-libs/libsdl -joystick.
Created attachment 233297 [details, diff] Add [joystick] to media-libs/libsdl dependency Just a little patch to inform the user that media-libs/sdl must be compiled with 'joystick' flag. This the default behavior but I inactivated it (why not?)
fixed in visualboyadvance-1.7.2-r4.ebuild
