如果安装好了图形库是不是不用换系统了

不得不告诉你，不是图形库没安装好的问题。
是sdl竟不去，初始化不了

你重装系统也不行?

你重装系统也不行?

路过围观，完全的表示不懂。

叫我怎么在gvim配置sdl2吧，我放弃ide了
@twtfcu3

看到你发的图，编程居然还有中文路径，你太强大了，改改了再用

我好像忽略了一个严重的问题，我的win7是64位机，而@twtfcu3

他的教程应该是32位的，请问这样有影响吗？是不是这个原因导致出现sdl2初始化失败

自已下源码编译

Mix_LoadMUS( )；这个函数能不能加载mp3文件，我这里测试不能
@DXKite

设置透明色出现崩溃，这个你应该知道原因吧@twtfcu3
代码如下；
#include <SDL2/SDL.h>
#include <SDL2/SDL_image.h>
int main(int argc,char**argv)
{
SDL_Init(SDL_INIT_VIDEO);
SDL_Init(SDL_INIT_EVERYTHING);
SDL_Window *win=SDL_CreateWindow("test",100,100,200,200,SDL_WINDOW_SHOWN);
SDL_Renderer*ren=SDL_CreateRenderer(win,-1,SDL_RENDERER_ACCELERATED|SDL_RENDERER_PRESENTVSYNC);
SDL_Surface *s=IMG_Load("8.jpeg");
Uint32 ck=SDL_MapRGB(s->format,0,0,0);
SDL_SetColorKey(s,SDL_TRUE,ck);
SDL_Texture *tex=SDL_CreateTextureFromSurface(ren,s);
SDL_RenderCopy(ren,tex,NULL,NULL);
SDL_Delay(10000);
SDL_FreeSurface(s);
SDL_DestroyWindow(win);
SDL_DestroyRenderer(ren);
SDL_DestroyTexture(tex);
SDL_Quit();
return 0;
}

加载的图不能直接操作

打印字体又出现问题了...这个是怎么回事@twtfcu3

//两份基本相同的代码，只不过一个用了vector，用了vector的代码输出不了中文，另一个/////简单的反而可以，这两个都可以直接运行的，@twtfcu3 @DXKite @TTHHR @小牛_牛sky //都用的TTF_RenderUTF8_Blended这个函数

看你代码我就发昏，。呃呃，睡了一下午，先试试简单的使用vector储存字符串，应该可以用的，肯定什么地方你弄错了，，其实vector我喜欢这样 vector<string> a={"a","b"};
cout<<a[0]<<a[1];
干嘛用指针啊，。。。麻烦，，
