第一次交叉编译基于群晖 213j(CPU:Armada 370)的iperf过程

前言

为了测试网络吞吐率，使用iperf，但是官网没有提供arm版，只能自己编译。

基础

系统:Ubuntu 17.04
一开始用CentOS 6.9，怎么着都编译不过去，报错”/lib64/libc.so.6: version `GLIBC_2.18’ not found (required by /lib64/libstdc++.so.6)”
编译器 : armada370-gcc493_glibc220_hard-GPL.txz
iperf : iperf v3.3

过程

结尾

关键点在于./configure 的时候要指定--host
