在通信设备领域，思科的路由器设备可以用CLI进行操作。这里介绍的开源项目klish是思科CLI风格(CISCO-like CLI)的框架。命令配置文件为xml格式。

源码：pkun/klish: The klish is a framework for implementing a CISCO-like CLI on a UNIX systems. It is configurable by XML files. - libcode

环境

Ubuntu 20.04.2 LTS

编译

版本：klish 2.2

//1. 运行autogen.sh生成configure文件

klish# ls

autogen.sh

klish# ./autogen.sh

Makefile.am: installing 'aux_scripts/depcomp'

autoreconf: Leaving directory `.'

生成configure文件

klish# ls

autogen.sh

configure  

//2. 运行configure生成Makefile文件

klish# ./configure

config.status: executing libtool commands

config.status: executing depfiles commands

生成makefile文件

klish# ls

autogen.sh

configure

Makefile

//3. make编译

klish# make

make[1]: Leaving directory '/workspace/klish'

//4. make install安装

klish# make install

Libraries have been installed in:

   /usr/local/lib

 /bin/mkdir -p '/usr/local/bin'

  /bin/bash ./libtool   --mode=install /usr/bin/install -c bin/clish bin/konfd bin/konf bin/sigexec '/usr/local/bin'

遇到过的问题

问题1

缺少宏定义：AC_PROG_LIBTOOL

# ./autogen.sh

+ mkdir -p m4

+ autoreconf -fvi

autoreconf: Entering directory `.'

autoreconf: configure.ac: not using Gettext

autoreconf: running: aclocal --force -I m4

configure.ac:417: warning: macro 'AM_LANGINFO_CODESET' not found in library

autoreconf: configure.ac: tracing

autoreconf: configure.ac: creating directory aux_scripts

autoreconf: configure.ac: not using Libtool

autoreconf: running: /usr/bin/autoconf --force

configure.ac:20: error: possibly undefined macro: AC_LIBTOOL_WIN32_DLL

      If this token and others are legitimate, please use m4_pattern_allow.

      See the Autoconf documentation.

configure.ac:21: error: possibly undefined macro: AC_PROG_LIBTOOL

configure.ac:431: error: possibly undefined macro: AM_LANGINFO_CODESET

autoreconf: /usr/bin/autoconf failed with exit status: 1

解决：

网上搜了下这个宏，发现是缺少了依赖库。安装了依赖库后可以继续往下走。

sudo apt-get install libtool

问题2

找不到头文件expat.h

# make

clish/shell/shell_expat.c:40:10: fatal error: expat.h: No such file or directory

 #include <expat.h>

          ^~~~~~~~~

compilation terminated.

Makefile:1798: recipe for target 'clish/shell/libclish_la-shell_expat.lo' failed

解决：

网上查询发现少了依赖库。安装后继续

# apt-get install libexpat1-dev

问题3

缺少XML_ParserCreate

libtool: link: gcc -Wall -g -O2 -o bin/.libs/clish bin/clish.o  ./.libs/libclish.so ./.libs/libkonf.so ./.libs/libtinyrl.so ./.libs/liblub.so -ldl

./.libs/libclish.so: undefined reference to `XML_SetUserData'

./.libs/libclish.so: undefined reference to `XML_Parse'

./.libs/libclish.so: undefined reference to `XML_SetElementHandler'

collect2: error: ld returned 1 exit status

make[1]: *** [bin/clish] Error 1

make[1]: Leaving directory '/home/klish'

Makefile:717: recipe for target 'all' failed

make: *** [all] Error 2

解决：

网上查询发现缺少库libxml2

# apt-cache search libxml

libxml2 - GNOME XML library

libxml2-dev - Development files for the GNOME XML library

# apt-get update

# apt-get install libxml2-dev

运行

klish-2.2# CLISH_PATH=xml-examples/klish/etc/clish bin/clish

> show

Syntax error: Unknown command
