Sdl.h stops everything

SDL Development

Hi,
I am using Dev-CPP (Win10)
when I write a simple “Hello World” it works no problem (console).
If I add #include <sdl.h> it fails to display anything at all.

#include
#include
#include <sdl.h> //works perfectly WITHOUT this line.

int main(int argc, char *argv[])
{
printf(“Hello World.\n”);
system(“PAUSE”);
return 0;
}
