SDL2 分段错误：./libio/genops.c：没有这样的文件或目录

Question

我不断收到段错误，我不确定我是否遗漏了一些东西，但我是 C 和 SDL2 新手，所以我希望也许有人可以看到我看不到的东西......抱歉对于混乱的代码！

main.c:

#include <SDL2/SDL.h>
#include <SDL2/SDL_image.h>
#include <stdbool.h>

#include "../include/globals.h"

SDL_Window *gWindow = NULL;
SDL_Renderer *gRenderer = NULL;
SDL_Surface *gHelloWorld = NULL;

int main(int argc, char* args[]){
    //Start up SDL and create window
    if(!init()){
        printf("Failed to initialize!\n");
    }
    else{
        //Load media
        if(!(create_sprite())){
            printf("Sprite initialization failed!\n");
        }
        else{
            //Apply the image
            SDL_Event e; 
            bool quit = false; 
            while(quit == false){ 
                while( SDL_PollEvent(&e)){ 
                    if(e.type == SDL_QUIT){ 
                        quit = true; 
                    }
                    else if (e.type == SDL_KEYDOWN){
                        switch (e.key.keysym.sym){
                            case SDLK_DOWN:
                                sprite_list[0].rect.y += 50;
                            case SDLK_UP:

                            case SDLK_ESCAPE:

                                break;
                        }
                    }
                } //main game loop
                SDL_RenderCopy(gRenderer, sprite_list[0].texture, NULL, &sprite_list[0].rect);

                SDL_RenderClear(gRenderer);
            }
        }
    }
    close();
    return 0;
}

globals.h：

#define SCREEN_WIDTH 640
#define SCREEN_HEIGHT 480

//define center since SDL2 doesn't have a function for fetching the center coordinates 
#define X_CENTER SCREEN_WIDTH / 2
#define Y_CENTER SCREEN_HEIGHT / 2

subsys.h：

bool init();
void close();

extern SDL_Window *gWindow;
extern SDL_Surface *gHelloWorld;
extern SDL_Renderer *gRenderer;

精灵.h：

#ifndef MYSTRUCTS_H
#define MYSTRUCTS_H
typedef struct {
    SDL_Texture *texture;
    SDL_Rect rect;
}Sprite;
#endif

extern Sprite *sprite_list;
extern int sprite_list_size;

void move_sprite();
bool create_sprite();

我尝试使用 GDB 来查看是否有任何明显的东西，但我得到的唯一错误消息是 ./libio/genops.c: No such file or directory。我没有做更多的调试，所以我很抱歉。

close()

中的

subsys.c

符号与libc符号

close

冲突。 https://linux.die.net/man/2/close

您可能想将其重命名为

app_close

或任何您想要的前缀。
