我使用以下链接构建我的工具链，crosscompiler 启用c ++支持：----- http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/
我正在使用Scratchbox＆amp; QEMU。
现在我在Scratchbox2中编译我的代码，c ++代码正在编译但是 无法运行它会抛出此错误：-------
./a.out: error while loading shared libraries: libstdc++.so
编译器版本：------------------
[SB2 simple armhf] ignite@ignite testing $ g++ --version
arm-unknown-linux-gnueabi-g++ (crosstool-NG 1.17.0) 4.7.3 20121001 (prerelease)

编译成功：---------------
[SB2 simple armhf]点燃@ ignite测试$ g ++ new.cpp
输出文件格式：----------------
[SB2 simple armhf] ignite@ignite testing $ file a.out
a.out: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically
linked (uses shared libs), for GNU/Linux 3.6.3, not stripped
抛出错误：---------
[SB2 simple armhf] ignite@ignite testing $ ./a.out
./a.out: error while loading shared libraries: libstdc++.so.6: cannot
open shared object file: No such file or directory
当我运行此命令时：---------＆gt;＆gt;＆gt;其中libstdc ++。所以 它显示了库
[SB2 simple armhf] ignite@ignite testing $ whereis libstdc++.so
libstdc++:

即使我运行ldconfig -v也存在相同的错误：-----

看起来你根本没有libstdc ++。so.6在目标上。 （“在目标上”的意思是“在Raspberry Pi上”。）
如果您的Raspberry运行Debian或Ubuntu，请尝试使用apt-get install libstdc++6。
您还可以尝试使用g++ -static -static-libstdc++ new.cpp静态编译程序，如果您在编译系统上有要链接的静态库，那么该程序应该可以正常工作。

您正在执行主机系统中的所有命令。您需要退出Scratchbox的命令模式并执行：
sb2 -e ./a.out
在目标中执行文件。

您对'whereis libstdc ++。so'的回复并未告诉您该库存在。这是一个空位置设置，说它找不到这样的东西。例如，尝试'whereis ls'来查看显示命令路径的非空集。

要将libstdc ++ 6安装到目标中，您需要发出：
sb2 -eR apt-get install libstdc ++ 6
