本文声明：
freeswitch版本:1.6
操作系统基本是最小安装
温馨提示:如果想更快的编译成功可以先把所有的yum的软件安装完成（及所有的yum命令执行一下）
步骤和问题解决
1.安装git
yum install git
2.获取源码
git clone https://freeswitch.org/stash/scm/fs/freeswitch.git freeswitch.git
3.按照官方文档搭建环境
官方文档地址
https://freeswitch.org/confluence/display/FREESWITCH/CentOS+7+and+RHEL+7
安装freeswitch的rpm的仓库
yum install -y http://files.freeswitch.org/freeswitch-release-1-6.noarch.rpm epel-release
安装开发环境(上面步骤需要成功)
yum install -y git gcc-c++ autoconf automake libtool wget python ncurses-devel zlib-devel libjpeg-devel openssl-devel e2fsprogs-devel sqlite-devel libcurl-devel pcre-devel speex-devel ldns-devel libedit-devel libxml2-devel libyuv-devel opus-devel libvpx-devel libvpx2* libdb4* libidn-devel unbound-devel libuuid-devel lua-devel libsndfile-devel yasm-devel
4.开始编译
编译
./bootstrap.sh -j
注意：执行失败提示( autoconf not found)
yum install autoconf automake libtool
再次编译
./bootstrap.sh -j
./configure
5.解决configure中出现的错误
1]The C++ compiler does not work. Please (re)install the C++ compiler
yum install gcc-c++
2]no usable zlib; please install zlib devel package or equivalent
yum install zlib-devel
3]Library requirements (sqlite3 >= 3.6.20) not met;
yum install sqlite-devel
4]Library requirements (libcurl >= 7.19) not met;
yum install curl-devel
5]Library requirements (libpcre >= 7.8) not met;
yum install pcre-devel
6]Library requirements (speex >= 1.2rc1 speexdsp >= 1.2rc1) not met;
yum install speex-devel
7]You need to either install libldns-dev or disable mod_enum in modules.conf
yum install ldns-devel
8]You need to either install libedit-dev (>= 2.11) or configure with –disable-core-libedit-support
yum install libedit-devel
9]OpenSSL >= 1.0.1e and associated developement headers required
yum install openssl-devel
成功后的结果应该是下图所示
默认情况的configure结果
6.解决编译时的错误
编译
make
6.1 Neither yasm nor nasm have been found.
yum install nasm -y
6.2 fatal error: lua.h: No such file or directory
yum install lua-devel
6.3 You must install libopus-dev to build mod_opus. Stop.
yum install opus-devel
./configure && make
6.4 You must install libsndfile-dev to build mod_sndfile.
yum install libsndfile-devel
./configure && make
编译成功结果
编译成功后的终端显示效果
7.安装到默认目录
安装
make install
结果
安装后的提示
提示
安装声音文件
这个是需要下载的，可以不用安装
make cd-moh-install && make cd-sounds-install
