How do you use the sdl2 library installed in the CXXDROID app

Answer 1

FWIW, that's a 17 part series which seems like a decent starter.

Answer 2

Google, YouTube. There are many examples of using it.

I tried this example that creates a black window for 5 sec:

https://dev.to/noah11012/using-sdl2-opening-a-window-79c

#include <SDL2/SDL.h>
#include <iostream>

int main()
{
if(SDL_Init(SDL_INIT_VIDEO) < 0)
{
std::cout << "Failed to initialize the SDL2 library\n";
return -1;
}

SDL_Window *window = SDL_CreateWindow("SDL2 Window",
SDL_WINDOWPOS_CENTERED,
SDL_WINDOWPOS_CENTERED,
680, 480,
0);

if(!window)
{
std::cout << "Failed to create window\n";
return -1;
}

SDL_Surface *window_surface = SDL_GetWindowSurface(window);

if(!window_surface)
{
std::cout << "Failed to get the surface from the window\n";
return -1;
}
SDL_UpdateWindowSurface(window);

SDL_Delay(5000);
}

Worked fine for me.
