Question

我正在尝试在使用GCC编译的C语言中使用SDL2但事件不起作用，例如，我无法使用SDL_QUIT关闭窗口。请问代码有什么问题吗？

#include <stdlib.h>
#include <stdio.h>
#include <SDL2/SDL.h>

int main(int argc, char** argv)
{
    if (SDL_Init(SDL_INIT_VIDEO) != 0) {
        fprintf(stdout,"Échec\n", SDL_GetError());
        return -1;
    }

    SDL_Window* windowImg = NULL;
    SDL_Renderer* renderImg = NULL;
    int quit = 0;
    SDL_Event e;

    windowImg = SDL_CreateWindow("Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 400, 400, SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE);
    renderImg = SDL_CreateRenderer(windowImg, -1, SDL_RENDERER_ACCELERATED);

    while (!quit) {
        while (SDL_PollEvent(&e) != 0) {
            if (e.type == SDL_QUIT) {
                quit = 1;
                break;
            }
        }
    }

    SDL_DestroyWindow(windowImg);
    SDL_Quit();

    return 0;
}

好的，我忘了在构建选项中链接库＆gt;链接器选项： -lSDL2main -lSDL2

SDL2事件在C中不起作用
