Public bug reported:
May also touch libsdl2-dev library.
Cannot get SDL2 to work.
Below is an example c file that calls the SDL2 library.
EXPECTED: a window with a red rectangle in it.
ACTUAL RESULTS: Instead, the background of the existing windows or
desktop shows through and no rectangle pops up.
BEGIN CODE
#include <SDL2/SDL.h>
int main()
{
SDL_Window *window;
SDL_Surface *surface;
SDL_Rect rect = {0, 0, 200, 200};
SDL_Init(SDL_INIT_EVERYTHING);
window = SDL_CreateWindow("test", SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED, 800, 600, SDL_WINDOW_SHOWN);
if (!window) {
fprintf(stderr, "main: %s\n", SDL_GetError());
return -1;
}
surface = SDL_GetWindowSurface(window);
if (!surface) {
fprintf(stderr, "main: %s\n", SDL_GetError());
return -1;
}
SDL_FillRect(surface, &rect, 0xffff0000);
SDL_UpdateWindowSurface(window);
SDL_Delay(1000);
SDL_DestroyWindow(window);
SDL_Quit();
}
END CODE
How to build: gcc example.c -lSDL2 -o example.out
The same issue happens on Debian Unstable. I also fired up a Fedora
instance and the above code compiled and worked as expected. Just not on
Debian Unstable or Ubuntu 17.04.
Here are all the various SDL packages installed at the moment:
sudo dpkg-query -l "*sdl*"
