[ft] Unable to initialize SDL: Unable to open a console terminal

[mahavishnu]

hi ,
I cleared that problem just by executing a.out with root permission.but now a 
segmentation fault occurs at

int width = 800;
int height = 600;
int videoFlags = SDL_SWSURFACE | SDL_RESIZABLE | SDL_DOUBLEBUF;
int bpp = 32;
SDL_Surface *screen;
screen=SDL_SetVideoMode(width, height, bpp, videoFlags);--->this line gives 
segmentation fault.
do i have to initialize something properly or what,please advice...
