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
root@ubuntu:~# mkdir soft
root@ubuntu:~# cd soft
root@ubuntu:~/soft# tar axf armada370-gcc493_glibc220_hard-GPL.txz
root@ubuntu:~/soft# tar axf iperf-3.3.tar.gz
root@ubuntu:~/soft# cd arm-unknown-linux-gnueabi/bin
root@ubuntu:~/soft/arm-unknown-linux-gnueabi/bin# export PATH=$PATH:`pwd`
root@ubuntu:~/soft/arm-unknown-linux-gnueabi/bin# mkdir ~/soft/iperf
root@ubuntu:~/soft/arm-unknown-linux-gnueabi/bin# cd ../../iperf-3.3/
root@ubuntu:~/soft/iperf-3.3# ./configure --host=arm-unknown-linux-gnueabi --prefix=/root/soft/iperf CXX=arm-unknown-linux-gnueabi-g++
root@ubuntu:~/soft/iperf-3.3# make -j 4 && make install
root@ubuntu:~/soft/iperf-3.3# cd ../iperf3/bin
root@ubuntu:~/soft/iperf/bin# file iperf3
iperf3: ELF 32-bit LSB executable,ARM,EABI5 version 1 (SYSV),dynamically linked,interpreter /lib/ld-linux-armhf.so.3,for GNU/Linux 2.6.32,not stripped
root@ubuntu:~/soft/iperf/bin# arm-unknown-linux-gnueabi-strip iperf3
root@ubuntu:~/soft/iperf/bin# file iperf3
iperf3: ELF 32-bit LSB executable,stripped
root@ubuntu:~/soft/iperf/bin# ll

drwxr-xr-x 2 root root 4096 12月 14 16:13 ./
drwxr-xr-x 6 root root 4096 12月 14 16:10 ../
-rwxr-xr-x 1 root root 5908 12月 14 16:13 iperf3
-rwxr-xr-x 1 root root 24072 12月 14 16:13 iperf3.nostrip
结尾
关键点在于./configure 的时候要指定--host
