移植 iftop 到海思 3559 平台

一、下载

http://www.ex-parrot.com/~pdw/iftop/

二、编译

报错 1

解决 1

在 config/config.sub 文件的第 231 行后面加一行 | aarch64-himix100 \ 就能认到了

报错 2

checking where to find pcap.h... /usr/include
checking for pcap_open_live in -lpcap... no
configure: error: can't find libpcap
  You're not going to get very far without libpcap.

解决 2

使用 --with-libpcap 引入交叉编译好的库--with-libpcap=/hisi_ext/3rd/libpcap-1.9.1/_install

报错 3

checking for a curses library containing mvchgat... none found
configure: error: Curses! Foiled again!
  (Can't find a curses library supporting mvchgat.)
  Consider installing ncurses.

分析 3

这个问题网上千篇一律的都是说安装库，但是我们这是交叉编译，直接命令安装库的方法是用不了的。

很显然，解决这个问题的重点就是如何正确引入 ncurses 相关项。

我一开始只是添加了 --with-ncurses=/hisi_ext/3rd/ncurses-6.2/_install LDFLAGS="-L/hisi_ext/3rd/ncurses-6.2/_install/lib -lncurses" CPPFLAGS="-I/hisi_ext/3rd/ncurses-6.2/_install/include" 这些项，头文件路径，库文件路径，库文件都正确引入了，但是仍然报一样的错误。理论上我已经引入了 ncurses ，应该不会有问题的。于是我仔细看了一下 configure 文件里是如何判断失败的，如何拷贝里面的判断方法，自己在外面手动编译一下才发现少引用了一个头文件路径 -I/hisi_ext/3rd/ncurses-6.2/_install/include/ncurses

测试

• 创建 main.c

$ cat main.c
#include <curses.h>

int main ()
{
  mvchgat(0, 0, 1, A_REVERSE, 0, NULL) ;
  return 0;
}

• 编译 main.c

$ aarch64-himix100-linux-gcc main.c -lncurses -L/hisi_ext/3rd/ncurses-6.2/_install/lib -I/hisi_ext/3rd/ncurses-6.2/_install/include/ncurses
In file included from main.c:1:0:
/hisi_ext/3rd/ncurses-6.2/_install/include/ncurses/curses.h:61:33: fatal error: ncurses/ncurses_dll.h: No such file or directory
#include <ncurses/ncurses_dll.h>
        ^
compilation terminated.

竟然报错，猜测 configure 文件里只要报错就算作失败，不管错误原因是什么，都是抛出一样的错误 ... Can't find a curses library supporting mvchgat ...。我们可以在 ncurses 路径里面找到缺失的 ncurses_dll.h 文件，如下：

$ ls ../ncurses-6.2/_install/include/ncurses
curses.h     cursesf.h  cursesp.h  cursslk.h  etip.h  menu.h      ncurses.h      panel.h  term_entry.h  tic.h
cursesapp.h  cursesm.h  cursesw.h  eti.h      form.h  nc_tparm.h  ncurses_dll.h  term.h   termcap.h     unctrl.h

所以引入这个新路径就可以编译通过

解决 3

./configure --prefix=/hisi_ext/3rd/iftop-0.17/_install\
--host=aarch64-himix100-linux\
--with-libpcap=/hisi_ext/3rd/libpcap-1.9.1/_install\
--with-ncurses=/hisi_ext/3rd/ncurses-6.2/_install\
LDFLAGS="-L/hisi_ext/3rd/ncurses-6.2/_install/lib -lncurses"\
CPPFLAGS="-I/hisi_ext/3rd/ncurses-6.2/_install/include/ncurses -I/hisi_ext/3rd/ncurses-6.2/_install/include"

三、安装

make
make install

四、使用

拷贝 iftop 到开发板后，运行

/mnt/wzy # ./iftop
./iftop: error while loading shared libraries: libpcap.so.1: cannot open shared object file: No such file or directory

解决：拷贝对应库到开发板的环境变量的 LD_LIBRARY_PATH 路径

用法

/mnt/wzy # ./iftop -h
iftop: display bandwidth usage on an interface by host

Synopsis: iftop -h | [-npbBP] [-i interface] [-f filter code] [-N net/mask]

   -h                  display this message
   -n                  don't do hostname lookups
   -N                  don't convert port numbers to services
   -p                  run in promiscuous mode (show traffic between other
                       hosts on the same network segment)
   -b                  don't display a bar graph of traffic
   -B                  Display bandwidth in bytes
   -i interface        listen on named interface
   -f filter code      use filter code to select packets to count
                       (default: none, but only IP packets are counted)
   -F net/mask         show traffic flows in/out of network
   -P                  show ports as well as hosts
   -m limit            sets the upper limit for the bandwidth scale
   -c config file      specifies an alternative configuration file

测试

/mnt/wzy # ./iftop -i eth0
interface: eth0
IP address is: 192.168.12.150
MAC address is: 00:0c:29:58:00:50
Error opening terminal: xterm.

解决：拷贝你交叉编译出来的 ncurses 目录到开发板，并修改环境变量为对应路径和值：

/mnt/wzy # env | grep -i term
TERMINFO=/mnt/wzy/ncurses-6.2/share/terminfo
TERM=xterm

四、用法略解

执行 ./iftop -i eth0 后串口终端显示结果(会动态刷新)如下所示：
