CentOS6.5升級autoconf版本，解決”Autoconf version 2.64 or higher is required“錯誤
安裝軟件時提示說需要Autoconf 2.64或更高的版本：
[root@wslu-cs wslu]# autoconf configure.ac:8: error: Autoconf version 2.64 or higher is required configure.ac:8: the top level autom4te: /usr/bin/m4 failed with exit status: 63
查詢當前版本：
[root@wslu-cs wslu]# rpm -qf /usr/bin/autoconf autoconf-2.63-5.1.el6.noarch
卸載當前版本：
[root@wslu-cs wslu]# rpm -e --nodeps autoconf-2.63
安裝最新版本：
[root@wslu-cs wslu]# wget ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz [root@wslu-cs wslu]# tar zxvf autoconf-2.69.tar.gz [root@wslu-cs wslu]# cd autoconf-2.69 [root@wslu-cs wslu]# ./configure --prefix=/usr/ [root@wslu-cs wslu]# make && make install
查看當前版本：
[root@wslu-cs autoconf-2.69]# /usr/bin/autoconf -V autoconf (GNU Autoconf) 2.69 Copyright (C) 2010 Free Software Foundation, Inc.
