一、问题描述

嵌入式Linux开发，Ubuntu下交叉编译报错：

error while loading shared libraries: libc++.so: cannot open shared object file: No such file or directory

二、问题分析

查看依赖

ms@ubuntu:~$ ldd ~/program
	linux-vdso.so.1 (0x00007ffda70b0000)
	libc++.so => not found
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f38d6e96000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f38d6af8000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f38d68e0000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f38d64ef000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f38d70b5000)
ms@ubuntu:~$ 

缺少libc++.so库

三、解决方案

安装对应的库

sudo apt-get install libc++-dev -y

或

sudo apt-g
