系统：Centos 6.4 64位；
FreeSWITCH版本：1.5
具体的安装过程参考FreeSWITCH 官网wiki (也可以参考我的博客《Centos6安装FreeSWITCH》)
从FreeSWITCH 安装过程./configure 时遇到sqlite 的问题开始：
checking for sqlite3 >= 3.6.20… Package sqlite3 was not found in the pkg-config search path. Perhaps you should add the directory containing `sqlite3.pc’ to the PKG_CONFIG_PATH environment variable No package ‘sqlite3′ found
configure: error: Library requirements (sqlite3 >= 3.6.20) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
应该是缺少开发包，于是就开始了这一路的开发包手工加载。
[root@localhost freeswitch]# yum install sqlite-devel
[root@localhost freeswitch]#./configure
[root@localhost freeswitch]# yum install libcurl-devel
[root@localhost freeswitch]#./configure
[root@localhost freeswitch]# yum install pcre
[root@localhost freeswitch]# yum install pcre-devel
[root@localhost freeswitch]#./configure
[root@localhost freeswitch]# yum install speex
[root@localhost freeswitch]# yum install speex-devel
[root@localhost freeswitch]#./configure
