Excuse me, where is the "SDL.h" file

https://github.com/udacity/CppND-Capstone-Snake-Game/blob/master/src/game.cpp#L60-#L64

If the randomize for "food" is currently on snake, there is no more food generated.
Qucikfix I've build.

void Game::PlaceFood() {
  int x, y;
  while (true) {
    x = random_w(engine);
    y = random_h(engine);
    // Check that the location is not occupied by a snake item before placing
    // food.
    if (!snake.SnakeCell(x, y)) {
      food.x = x;
      food.y = y;
      return;
    } else {
      continue;
    }
  }
}

For easier maintenance and build, I suggest using "Conan package manager".

Hello, I notice that this project just uses SDL2 library, but SDL2_Image and SDL2_ttf are also important in reality. So I create a new project using SDL2, SDL2_Image, and SDL2_ttf to improve the ability of this project by adding some game UI. I try to make my project simple enough so that any beginner can learn how to SDL2, SDL2_Image, and SDL2_ttf libraries to write some simple projects just like me. And as a beginner, my project must have some bugs, any suggestions are welcome. The address of my project is here.
Thank you!

Had a minor issue building this project.

Adding the following to CMakeLists.txt solved the issue:
set (CMAKE_CXX_STANDARD 17)

Perhaps just an issue with my default setting but might be worth considering for ease of use.

If the snake fills the entire screen upon eating the last food item (in other words, winning the game), Game::PlaceFood will run forever as it attempts to find an x and y value that aren't occupied by the snake.

Your random_w should be 0 to screen_width/grid_width and random_h should be 0 to
screen_height/grid_height. Otherwise, you will place food out of screen sometimes.

  random_w(0, static_cast<int>(screen_width/grid_width)),
  random_h(0, static_cast<int>(screen_width/grid_height)

scenario 1; not included SDL2 dir;

fatal error: SDL.h: No such file or directory
    5 | #include "SDL.h"
      |          ^~~~~~~
compilation terminated.

scenario 2; included SDL2 dir but still linker error

fatal error: SDL.h: No such file or directory
    5 | #include "SDL.h"
      |          ^~~~~~~
compilation terminated.

Fixed by adding to CmakeLists.txt
`
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/usr/include/SDL2")`

After building the clean and untouched project using:
cmake .. && make
I received the following error:
Renderer could not be created. SDL_Error: Couldn't find matching render driver

I ran everything on the provided workspace with GPU enabled in the browser editor. I get the same error in the VS Code Terminal.

Does anyone have an idea what's going on?

Thanks for the feedback!

hey guys!
Is there anyway to compile and run this repo on M1 Pro?
I keep running into issues when I attempt to do that.
