Question

我已经编写了一个基本的CSFML程序来尝试学习CSFML。当我尝试编译它时，我收到链接器错误。我无法弄清楚为什么会这样。程序，编译命令和编译器的输出都在下面。我是一个相当干净的ubuntu副本。

test.c的：

#include <SFML/Window.h>
#include <SFML/Graphics.h>
int main(){
    sfVideoMode mode = {800,600,32};
    sfRenderWindow *window = sfRenderWindow_create(mode,"Hello, CSFML", sfResize | sfClose, NULL);
    sfRectangleShape *shape = sfRectangleShape_create();
    sfRectangleShape_setFillColor(shape,sfWhite);
    while(sfRenderWindow_isOpen(window)){
            sfEvent event;
            while(sfRenderWindow_pollEvent(window,&event)){
                    if(event.type == sfEvtClosed){
                            sfRenderWindow_close(window);
                    }
            }
            sfRenderWindow_clear(window,sfBlack);
            sfRenderWindow_drawRectangleShape(window,shape,NULL);
            sfRenderWindow_display(window);
    }

    return 0;
}

编译使用：

gcc -o test test.c

输出gcc：

Per @ NominalAnimal的评论：

使用gcc -Wall -O2 test.c -lcsfml-graphics -lcsfml-window -o test编译程序。

-lcsfml-graphics告诉编译器将可执行文件与csfml-graphics库（Linux上的“libcsfml-graphics.so”或“libcsfml-graphics.a”）链接，-lcsfml-window与GROUP BY Date类似。 csfml-window库。

（注意：l是“字母”，而不是“数字一”，这里。）
