交叉編譯iperf測試arm開發板上wifi模塊的網絡流量速度
1.在pc機端安裝iperf軟件
luther@gliethttp:~$ sudo apt-get install iperf
2.交叉編譯iperf到arm開發板上
luther@gliethttp:~$ wget http://downloads.sourceforge.net/iperf/iperf-2.0.4.tar.gz?modtime=1207626803&big_mirror=0
luther@gliethttp:~$ tar zxvf iperf-2.0.4.tar.gz
luther@gliethttp:~/iperf-2.0.4$ ./configure --help
luther@gliethttp:~/iperf-2.0.4$ ./configure --host=arm-linux
luther@gliethttp:~/iperf-2.0.4$ vim config.h
修改如下內容：可以通過./configure查看正常編譯的配置信息,將差異修改到arm交叉編譯生成的config.h中
...
#define HAVE_MALLOC 0 改爲 #define HAVE_MALLOC 1
/* #undef HAVE_QUAD_SUPPORT */ 改爲 #define HAVE_QUAD_SUPPORT 1
#define malloc rpl_malloc 改爲 /* #undef malloc */
luther@gliethttp:~/iperf-2.0.4$ make -j4 //我的pc爲雙核
luther@gliethttp:~/iperf-2.0.4$ ll src/iperf
-rwxr-xr-x 1 luther luther 75K 2008-11-25 16:07 src/iperf
這樣我們運行到arm上的iperf程序就編譯成功了,將它拷貝到arm板子上.
1.在pc上以服務器模式啓動iperf
luther@gliethttp:~$ iperf -s
2.將交叉編譯的iperf拷貝到arm開發板上
/ # tftp -r iperf -g 192.168.100
/ # chmod 755 iperf
/ # ./iperf -c 192.168.2.65 -i 5 -t 60
//192.168.2.65是我的pc端ip地址
//-i 5表示arm板子上啓動的client每5s打印一下速度信息;
//-t 60表示測試60s;
//默認使用tcp傳輸
/ # ./iperf -c 192.168.2.65 -i 5 -t 60
