源代码使用SDL_ttf库里的字体加载等函数
sdl崩溃闪退
怎么解决？

#include <SDL.h>
#include <SDL_ttf.h>
int main(){
SDL_Init(SDL_INIT_EVERYTHING);
TTF_Init();
SDL_Surface *a_1=NULL,*a_2=NULL;
TTF_Font *ttf_1=NULL;
SDL_Color ttf_1c={0,0,0};
a_1=SDL_SetVideoMode(1080,1920,32,SDL_SWSURFACE);
ttf_1=TTF_OpenFont("/zy/en.ttf",26);
a_2=TTF_RenderText_Solid(ttf_1,"Happy birthday to you.",ttf_1c);
SDL_BlitSurface(a_2,NULL,a_1,NULL);
SDL_Flip(a_1);
SDL_Delay(3000);
}

在安卓上根本不会有你写的这个路径，把字体路径改对了再说，改到你的ttf_1不为NULL为止。

#include <SDL.h>
#include <SDL_mixer.h>
#include <SDL_image.h>
#include <SDL_events.h>
#include <SDL_thread.h>
#include "SDL_auxiliary.h"
SDL_Thread *t_1;//建立线程指针
bool quit_main;
#define LENGTH 1080
#define HIGH 1920
int play(void* data) {
Mix_Music *m=(Mix_Music*)data;
while (quit_main != 1) {/*判断主函数是否结束*/
Mix_PlayMusic(m, -1);
}
return 1;
}
int main() {
SDL_Init(SDL_INIT_EVERYTHING);//启动sdl

SDL_Flip(a_1);
break;
}
}
}
SDL_Quit();
quit_main = 1;
return 0;
}

头文件的内容：
//图像居中点
SDL_Rect middle_xy(int l,int h,SDL_Rect image_lh){
SDL_Rect re;
re.x=(l-image_lh.x)/2;
re.y=(h-image_lh.y)/2;
return re;
}
//关键色
void key_color(SDL_Surface *file,Uint8 r,Uint8 g,Uint8 b){
Uint32 color=SDL_MapRGB(file->format,r,g,b);
SDL_SetColorKey( file, SDL_SRCCOLORKEY, color );
}
// 图像优化
SDL_Surface *image_opi(SDL_Surface * a) {
SDL_Surface *b = NULL;
b = SDL_DisplayFormat(a);
SDL_FreeSurface(a);
return a;
}
// 图像批量加载
int bulk_load_image(char* file_name[], SDL_Surface *file[], int i) {
SDL_Surface *ls = NULL;
for (int j = 0; j < i; j++) {
ls = IMG_Load(file_name[j]);
file[j] = ls;
}
}

关于播放的我也不懂，这个代码我测试是ok的，给你吧
