CLI框架：klish安装与使用
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。
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

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

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
