在g ++上使用Linux上的SDL2？

Question

1 #include "SDL2/SDL.h" 

    3 
    4 int main(int argc, char* args[]) 
    5 { 
    6  SDL_Init(SDL_INIT_EVERYTHING); 

    8  SDL_QUIT(); 
    9  return 0; 
10 } 

我已經安裝SDL2在Debian倉庫和我運行

g++ -o test.cpp a.out -lSDL2 

，我收到了一大堆的錯誤：

a.out:(.rodata+0x0): multiple definition of `_IO_stdin_used'

/usr/bin/ld: error in a.out(.eh_frame); no .eh_frame_hdr table will be created.

我已經試過

g++ test.cpp $(pkg-config --cflags --libs sdl2) 

並獲得：

test.cpp: In function ‘int main(int, char**)’: 
test.cpp:6:14: error: ‘(SDL_EventType)256u’ cannot be used as a function 

我不知道是什麼導致這些錯誤。 適當的頭文件存在於

的/ usr /包括/ SDL2/

目錄。難道我做錯了什麼？

Answer 1

的頭必須是：<SDL2/SDL.h>
的退出功能：SDL_Quit();
命令：g++ teste.cpp -o filename -lSDL2

Answer 2

像Tietbohl說

SDL_QUIT是枚舉SDL_EventType的一部分 http://wiki.libsdl.org/SDL_EventType

你應該使用SDL_QUIT（）; http://wiki.libsdl.org/SDL_Quit

Answer 3

//錯誤：g++ -o test.cpp a.out -lSDL2

//好：g++ test.cpp -lSDL2（a.out的隱含的）

//更好：g++ test.cpp -g -pedantic -o test -lSDL2

我懷疑的主要問題可能只是一直把g ++參數的順序錯誤。
