1.我发现读图就不成功，好像是路径原因，但是路径是
正确的
，
请问：tex=IMG_LoadTexture(ren,"F:/图片/工作/5.jpeg");这条语句有问题吗？

@啊o额iu鱼

f:\\图片\\工作\\5.jpeg

呃呃，我对文件路径不熟，，

慢慢来，在写大程序的时候每个模块建议在写的时候就调试一下，不然错误吓死你，，，，

路径不用中文最好

#include<SDL2/SDL.h>
#include<SDL2/SDL_image.h>
int main(int argc,char **argv)
{
SDL_Window *w=NULL;
SDL_Texture *tex = NULL;// 画刷
SDL_Renderer *ren=NULL;SDL_Init(SDL_INIT_EVERYTHING);
w = SDL_CreateWindow("图片测试", 100, 100, 480, 640, SDL_WINDOW_OPENGL | SDL_WINDOW_RESIZABLE | SDL_WINDOW_BORDERLESS);// 配置窗口参数并创建
ren = SDL_CreateRenderer(w, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);// 为创建的窗口配置渲染器
tex=IMG_LoadTexture(ren,"f:\\图片\\工作\\1.jpeg");
SDL_RenderCopy(ren,tex,NULL,NULL);
SDL_RenderPresent(ren);
SDL_Delay(2000);
return 0;
}
@twtfcu3 @DXKite

#include<iostream>
#include<SDL2/SDL.h>
#include<SDL2/SDL_image.h>
int main(int argc,char **argv)
{
if (SDL_Init(SDL_INIT_EVERYTHING) == -1){
std::cout << SDL_GetError() << std::endl;
return 1;}
SDL_Window *win = nullptr;
win = SDL_CreateWindow("Hello World!", 100, 100, 640, 480, SDL_WINDOW_SHOWN);
if (win == nullptr){
std::cout << SDL_GetError() << std::endl;
return 1;
}
SDL_Renderer *ren = nullptr;
ren = SDL_CreateRenderer(win, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
if (ren == nullptr){
std::cout << SDL_GetError() << std::endl;
return 1;
}
SDL_Texture*tex=IMG_LoadTexture(ren,"f:\\图片\\工作\\1.jpeg");
SDL_RenderClear(ren);
SDL_RenderCopy(ren, tex, NULL, NULL);
SDL_RenderPresent(ren);
SDL_Delay(2000);
SDL_DestroyTexture(tex);
SDL_DestroyRenderer(ren);
SDL_DestroyWindow(win);
SDL_Quit();
return 0;
}

却出现这个错误

SDL_RECT pos;
pos.x=10;
这两条语句合法吗？codeblocks报错
@twtfcu3 @DXKite

路过。。老班还在，不玩手机。。。

#include<iostream>
#include "SDL2/SDL.h"
#include "SDL2/SDL_image.h"
int main(int argc,char **argv)
{ SDL_Init(SDL_INIT_EVERYTHING) ;
SDL_Window *win = nullptr;
win = SDL_CreateWindow("Hello World!", 100, 100, 640, 480, SDL_WINDOW_SHOWN);
SDL_Renderer *ren = nullptr;
ren = SDL_CreateRenderer(win, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);SDL_RWops *r=SDL_RWFromFile("/storage/extSdCard/sdl/7.gif");
SDL_Texture*tex=IMG_LoadGIF(r);
SDL_RenderClear(ren);
SDL_RenderCopy(ren, tex, NULL, NULL);
SDL_RenderPresent(ren);
SDL_Delay(2000);
SDL_Quit();
return 0;
}

你确定文档说明可以使用gif图

sdl官方哪有说明

错误已经查清楚了，是sdl_init进不去，不过这是什么原因呢？可以编译
@twtfcu3 @DXKite @TTHHR @小牛_牛sky @疯人院的女孩 @啊o额iu鱼

sdl_init()后输出SDL_GetError()看错误原因

你初始化传参出错,win下是不会有重力系统的

SDL_INIM_VIDEO

楼上+1,也遇到过那个错误
