由于javafx支持Raspberry PI.我想在帧缓冲区中运行FX应用程序.我正在使用Lubuntu LCD显示图像.

当我尝试运行JavaFX应用程序时

java -Djavafx.platform=eglfb Hello.jar

我收到以下错误

我正在使用java8嵌入式hardfloat.

可能重复:
是否可以安装没有Visual Studio的c#编译器？

我刚刚完成了Global Game Jam 13,我在那里担任艺术家.我有游戏的文件,但我不知道如何运行它们.它是文件夹中的所有.cs文件和文件夹.如何制作可执行文件？

我知道字符串的长度应为n + 1,但由于某种原因,我的程序将sizeof(字符串)打印为n-2.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char name [] = "Tom";
    int x = sizeof(name);
    int i;

    printf("sizeof(name) = %d\n", i);

    for(i = 0; i < x; i++)
    {
        printf("Character at %d is %c\n", i, name[i]);
    }

    return 0;
} 

有谁能解释为什么？
