    Exclamation SDL2 Compilation Error in C

    Hey guys,
    So I'm trying to get SDL2 set up on my Ubuntu machine (18.04).
    I've written the following code so far
    Code:
    #include <stdio.h>
     #include <SDL2/SDL.h>
      #include <stdlib.h>
    
    #define SCREEN_WIDTH 640
      #define SCREEN_HEIGHT 480
    
    int main()
      {
    SDL_WINDOW* window;
    
     if(SDL_Init(SDL_INIT_VIDEO)!= 0){
     fprintf(stderr, "Could not initialize SDL Video: %s\n", SDL_GetError());
     }
    
     window = SDL_CreateWindow("hello", 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);
    
     if(window == NULL) {
     fprintf(stderr, "Could not create window: %s\n", SDL_GetError());
     }
     return 0;
     }
    Tried compiling using "gcc -o game game.c `sdl2-config --cflags --libs`" as well as with "gcc -o -lSDL2 game game.c". Each time it shows the same error:

    error: unknown type name ‘SDL_WINDOW’; did you mean ‘SDL_LINE’?
    SDL_WINDOW* window;

    Please help! I've tried uninstalling and reinstalling. Thanks.

    C is case sensitive.

    The type is SDL_Window
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
