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
checking for libldns >= 1.6.6... checking for ldns_str2rdf_a in -lldns... no
configure: error: You need to either install libldns-dev or disable mod_enum in modules.conf #
按提示没有找到libldns-dev 包，所以我选择disable mod_enum，做法如下：
[root@localhost freeswitch]#vi modules.conf
#applications/mod_enum
[root@localhost freeswitch]#./configure
configure: error: You need to either install libedit-dev (>= 2.11) or configure with --disable-core-libedit-support
[root@localhost freeswitch]#yum search libedit-dev
=============== N/S Matched: libedit-dev ========================
libedit-devel.i686 : Development files for libedit
libedit-devel.x86_64 : Development files for libedit
[root@localhost freeswitch]#yum install libedit-devel
[root@localhost freeswitch]#./configure
至此，freeSWITCH的配置已经完成。
