ux_con is a Linux host program and has actually nothing to do with L4
per se. It's just a program to visualize a framebuffer. It is compiled
and linked with $(CC). Maybe the problem is that glibc and the libsdl
don't fit quite well?

Does the following test program work?

#include "SDL.h"
int main(void)
{
  SDL_Init(SDL_INIT_VIDEO | SDL_INIT_TIMER);
  return 0;
}

with
gcc -W -Wall -o sdltest $(sdl-config --cflags --libs) sdltest.c
