csync2安装报错&解决

跟着linuxtone论坛前辈写的教程，做csync2+inotify同步实验，在安装csync2的时候出现了两个错误。

错误一：

[root@file2 csync2-1.34]# make

yacc  -d `test -f ‘cfgfile_parser.y’ || echo ‘./’`cfgfile_parser.y

/bin/sh: yacc: command not found

make: *** [cfgfile_parser.c] 错误 127

这个错误，报yacc命令么有找到，简单干脆的安装yacc的相关包：

[root@file2 csync2-1.34]# yum -y install yacc*

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

* addons: mirrors.163.com

* base: mirrors.163.com

* extras: mirrors.163.com

* updates: mirrors.163.com

Setting up Install Process

No package yacc* available.

Nothing to do

结果竟然告诉我没有这个包，于是google，知道了，原来是要安装byacc的包，于是：

[root@file2 csync2-1.34]# yum -y install *yacc

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

* addons: mirrors.163.com

* base: mirrors.163.com

* extras: mirrors.163.com

* updates: mirrors.163.com

之后make clean&&./configure&&make报第二个错误：

/bin/sh /opt/tool/csync2/csync2-1.34/missing –run flex   `test -f cfgfile_scanner.l || echo ‘./’`cfgfile_scanner.l

/opt/tool/csync2/csync2-1.34/missing: line 46: flex: command not found

sed ‘/^#/ s|\.c|cfgfile_scanner.c|’ .c >cfgfile_scanner.c

sed：无法读取 .c：没有那个文件或目录

make[1]: *** [cfgfile_scanner.c] 错误 2

蛋疼，看了看，有个warning提到flex这个东西，不知道什么东西，习惯性yum：

[root@file2 csync2-1.34]# yum -y install flex

Loaded plugins: fastestmirror

* addons: mirrors.163.com

丫的，还真有这个东西！安装完成这个flex，然后make clean && ./configure&&make&&make install，果然OK了.
