Oh, X is not linked to. If this is intentional, run with -curses flag,
if not recompile qemu after installing X development libraries.
You should be able to compile the following program without errors:
#include <SDL.h>
#if defined(SDL_VIDEO_DRIVER_X11)
#include <X11/XKBlib.h>
#else
#error No x11 support
#endif
int main(void) { return 0; }
You can also try applying the following patch, it might give
you more info.
