Question

我正在为raspi编写一个程序（参见git magic-number ）使用arm-bcm2708编译器。但是，当我试图让它在raspi2上运行时，我遇到了问题。我现在已经转向使用arm-linux-gnueabihf-g ++（参见git pukster/omxplayer-sync-2 ）。我花了大部分时间试图让这个交叉编译器工作，最终编译ffmpeg，但现在它抱怨它找不到string。

我将包含一个说明问题的最小工作示例（使用helloworld程序），同时使用相同的g ++调用。如果您有兴趣查看完整代码，可以在我的github帐户中找到它pukster/omxplayer-sync3

我需要有更多编译器洞察力的人来帮助我诊断这个问题。

helloworld.c

#include<stdio.h>
#include<string>

main()
{
    printf("Hello World");    
}

make.sh

#!/bin/bash

编辑：排查输出

find /mnt/CYBRAN/raspi1/usr/include/ -type l

的输出

修改当我在其中一个ls目录上执行-isystem时，我可以看到文件string存在，但我仍然得到同样的抱怨。这是pukster/omxplayer-sync3

提到的兼容性问题

arm-linux-gnueabihg -g ++找不到dbus头文件
