centos 7.9编译和安装freeswitch-1.10.9
前言
freswitch在centos7下编译总体上还是步骤比较复杂的。
忠告
千万别使用 CentOS 部署 FreeSWITCH ！！！
以下大部分都是笔者用 CentOS7 自编译踩得坑。
建议直接 Debian 安装官方编译好的包！！！可以少踩很多坑（严重怀疑官方歧视 CentOS）。
一、环境
centos 7.9
freeswitch 1.10.9
安装依赖
yum install gcc gcc-c++ 注意gcc需要4.8.5不能太高
yum install -y wget zlib-devel libjpeg-devel freetype-devel
官方插件
yum install -y epel-release
yum install -y git alsa-lib-devel autoconf automake bison broadvoice-devel bzip2 curl-devel libdb4-devel e2fsprogs-devel erlang flite-devel g722_1-devel gcc-c++ gdbm-devel gnutls-devel ilbc2-devel ldns-devel libcodec2-devel libcurl-devel libedit-devel libidn-devel libjpeg-devel libmemcached-devel libogg-devel libsilk-devel libsndfile-devel libtheora-devel libtiff-devel libtool libuuid-devel libvorbis-devel libxml2-devel lua-devel lzo-devel mongo-c-driver-devel ncurses-devel net-snmp-devel openssl-devel opus-devel pcre-devel perl perl-ExtUtils-Embed pkgconfig portaudio-devel postgresql-devel python-devel python-devel soundtouch-devel speex-devel sqlite-devel unbound-devel unixODBC-devel wget which yasm zlib-devel libshout-devel libmpg123-devel lame-devel rpm-build libX11-devel libyuv-devel
安装高版本cmake
wget https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz
tar -zvxf cmake-3.23.0.tar.gz
cd cmake-3.23.0
./bootstrap //编译
make //安装
make install
#链接
sudo ln -sf /usr/local/bin/cmake /usr/bin/cmake
sudo ln -sf /usr/local/bin/cpack /usr/bin/cpack
sudo ln -sf /usr/local/bin/ctest /usr/bin/ctestautoconf-2.71及以上版本
下载链接：http://mirrors.kernel.org/gnu/autoconf/
cd /usr/local/src
tar xzvf autoconf-2.71.tar.gz
cd autoconf-2.71
./configure //做相关编译前的环境检查
make
make install安装yasm
#安装
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar -xvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure
make && make install
cd ..首先安装nasm
wget https://www.nasm.us/pub/nasm/releasebuilds/2.14/nasm-2.14.tar.gz
tar -zxvf nasm-2.14.tar.gz
cd nasm-2.14
./configure
make
make install
二、下载源码
freeswitch下载地址： https://github.com/signalwire/freeswitch.git
另外有两个比较重新的库需要手动安装，分别是spandsp和sofia-sip
下载命令：
cd /data
git clone -b v1.10.9 https://github.com/signalwire/freeswitch
cd /data/freeswitch
git clone https://github.com/freeswitch/spandsp.git
git clone https://github.com/freeswitch/sofia-sip.git三、编译
.安装 epel扩展和文件传输工具lrzsz
yum install -y epel-release lrzsz
.安装yasm
yum -y install yasm
1. 编译必需库
首先，要先编译spandsp和sofia-sip， 否则freeswitch在configure阶段会报错。
#编译spandsp
cd /data/freeswitch/spandsp
./bootstrap.sh
./configure
make
make install#编译sofia-sip
cd /data/freeswitch/sofia-sip
./bootstrap.sh
./configure
make
make install添加库的路径到系统
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH}
ldconfig
2. 修改module.conf
下面则是安装freeswitch， 由于freeswitch支持动态编译和动态加载，一些不需要的模块可以不编译，如：mod_signalwire、mod_av，修改方法：
找到module.conf文件，找到mod_signalwire和mod_av注释掉，修改如下：
#applications/mod_signalwire
#applications/mod_av
3. 编译freeswitch
有了前两步的准备，编译freeswitch基本就不会遇到问题了，命令如下：
cd /data/freeswitch
./bootstrap.sh
./configure --enable-portable-binary --prefix=/usr/local/freeswitch --with-gnu-ld --with-python --with-openssl --enable-core-odbc-support --enable-zrtp
make
make install编译完成后，会出现下面信息：

执行./configure，做相关编译前的环境检查，错误处理如下：
4.1 安装pcre
checking for libpcre >= 7.8... Package libpcre was not found in the pkg-config search path. Perhaps you should add the directory containing `libpcre.pc' to the PKG_CONFIG_PATH environment variable No package 'libpcre' found
configure: error: Library requirements (libpcre >= 7.8) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
少包，执行：
yum install pcre
yum install pcre-devel解决
4.2 安装speex
checking for speex >= 1.2rc1 speexdsp >= 1.2rc1... Package speex was not found in the pkg-config search path. Perhaps you should add the directory containing `speex.pc' to the PKG_CONFIG_PATH environment variable No package 'speex' found Package speexdsp was not found in the pkg-config search path. Perhaps you should add the directory containing `speexdsp.pc' to the PKG_CONFIG_PATH environment variable No package 'speexdsp' found
configure: error: Library requirements (speex >= 1.2rc1 speexdsp >= 1.2rc1) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
执行：
yum install speex
yum install speex-devel
4.3 屏蔽libldns
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
vi modules.conf
#applications/mod_enum
4.4 安装libedit-dev
configure: error: You need to either install libedit-dev (>= 2.11) or configure with --disable-core-libedit-support
yum install libedit-devel
4.5、安装sounds声音文件
make sounds-install
make moh-install
4.6、注释掉mod_av
making all mod_av
make[4]: Entering directory `/freeswitch/src/mod/applications/mod_av'
Makefile:1442: *** You must install libavformat-dev and libswscale-dev to build mod_av. Stop.
make[4]: Leaving directory `/freeswitch/src/mod/applications/mod_av'
vi modules.conf
#applications/mod_av
或者安装
wget https://libav.org/releases/libav-12.3.tar.gz
libav 12.3 - Download, Browsing & More | Fossies Archive
tar -xf libav-12.3.tar.gz
cd libav-12.3
./configure --enable-pic --enable-shared --enable-libx264 --enable-gpl --extra-libs="-ldl"
make
make install
注意，版本必须是12.3的版本，不然报错
avformat.c: In function 'no_video_decode_packets':
avformat.c:2464:59: error: 'AVStream {aka struct AVStream}' has no member named 'codecpar'; did you mean 'codec'?
switch_packetizer_feed_extradata(context->packetizer, st->codecpar->extradata, st->codecpar->extradata_size);这是你的libav版本不对，你要用12.3的版本，之后的版本去掉了codec的指针，用了新的接口，对应mod_av不兼容。要么修改mod_av的源码把对应函数换成最新的，要么使用12.3的版本
但是，视频会议报错:

另外，尝试安装ffmpeg-devel
直接用 Debian 系统安装 FreeSWITCH ，不需要自己苦逼的编译安装
mod_av 需要 libavformat-dev，但 CentOS 没有，通过第三方 yum 库安装 ffmpeg-devel 包实现（yum 的 FreeSWITCH 版本里面是没有 mod_av、mod_b64、mod_png 的，所以上面的安装也就没有）：
rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
yum install -y ffmpeg-devel成功解决报错问题（Cannot find encoder id: 28）。
#########################
libav库
libav库的编译安装是可选的。
如果需要fs的mod_av模块，就要首先编译安装libav库。
使用ffmpeg库无法正常编译安装mod_av，过程较蛋疼。
编译安装libav库，要首先安装libx264库，否则mod_av库的编译还是会报错。
#编译安装libx264
wget -c http://files.freeswitch.org/downloads/libs/libx264.tar.bz2
tar -jxvf libx264.tar.bz2
cd libx264
./configure --enable-static --enable-shared --prefix=/usr
make
sudo make install
sudo cp /usr/lib/pkgconfig/x264.pc /usr/lib64/pkgconfig/
sudo cp /usr/lib/libx264.so /usr/lib64/
sudo cp /usr/lib/libx264.a /usr/lib64/
#编译安装libav
wget -c http://files.freeswitch.org/downloads/libs/libav-12.tar.bz2
tar -jxvf libav-12.tar.bz2
cd libav
./configure --enable-pic --enable-shared --enable-libx264 --enable-gpl --extra-libs="-ldl" --extra-cflags=-I/usr/include --extra-ldflags=-L/usr/lib64
make
sudo make install
sudo cp /usr/local/lib/pkgconfig/libavcodec.pc /usr/local/lib/pkgconfig/libavdevice.pc /usr/local/lib/pkgconfig/libavfilter.pc /usr/local/lib/pkgconfig/libavformat.pc /usr/local/lib/pkgconfig/libavresample.pc /usr/local/lib/pkgconfig/libavutil.pc /usr/local/lib/pkgconfig/libswscale.pc /usr/lib64/pkgconfig/
sudo ldconfig
4.7、注释掉mod_lua
make[4]: Entering directory `//freeswitch/src/mod/languages/mod_lua'
CXX mod_lua_la-mod_lua.lo
mod_lua.cpp:37:17: fatal error: lua.h: No such file or directory
#include "lua.h"
#languages/mod_lua
4.8、安装opus-devel
错误提示：You must install libopus-dev to build mod_opus
yum -y install opus-devel如果还是报这个错误，在 Makefile 就注释这两行，暂时直接屏蔽，待确认（已放弃）：
# 大概是在第 896、897 行
vim freeswitch/src/mod/codecs/mod_opus/Makefile
#install: error
#all: error
##########################################
这里单独说一下opus的安装，安装fs的时候可能会报错：“You must install libopus-dev to build mod_opus”，
解决方法：是手动安装opus-devel和opus，
RPM resource opus-devel
https://centos.pkgs.org/7/centos-x86_64/opus-1.0.2-6.el7.x86_64.rpm.html
例如我是通过rpm安装的：先下载opus-devel和opus的rpm包，然后执行：
- rpm -ivh opus-devel-1.1.1-2.el7.x86_64.rpm
- rpm -ivh opus-1.1.1-2.el7.x86_64.rpm。
安装完opus和opus-devel后，重新./configure并执行make clean，否则可能会有问题，这一点在这里有讲到。
很有可能在手动安装opus的时候系统会提示已安装过opus发生冲突，这时候执行yum remove opus卸载掉原来的opus即可。
关于opus这个模块，网上很多文章给出解决方案是修改Makefile文件绕过这个模块，但是本人并不推荐，因为fs的一些功能是依赖opus的（例如webrtc）。
-----------------------------------------
默认安装 mod_opus，该插件安装失败的解决方案
问题，查询configure.consolelog.txt，可以发现项目依赖opus 1.1版本
#查看系统支持的opus版本：
yum list opus #可见系统只支持 1.0.2-6.el7
#因此先卸载
yum remove -y opus
#重新安装 1.1版本
#先下载 opus 1.1
wget http://pkgrepo.linuxtech.net/el6/release/x86_64/libopus-1.1-1.el6.x86_64.rpm
#安装
rpm -Uvh libopus-1.1-1.el6.x86_64.rpm
#再下载opus-devel 1.1
wget http://pkgrepo.linuxtech.net/el6/release/x86_64/libopus-devel-1.1-1.el6.x86_64.rpm
#安装
rpm -Uvh libopus-devel-1.1-1.el6.x86_64.rpm
#重新执行
./configure --prefix=/usr/local/freeswitch_1_6_20 --disable-multilib --with-lib-subdir=/usr/lib64 > configure.consolelog.txt #配置编译环境.
checking for opus >= 1.1... yes #依赖检查通过
#重新 make 即可成功 4.9、安装 libks
# libks
git clone https://github.com/signalwire/libks.git
cd libks
/usr/local/bin/cmake .
make
sudo make install4.10、安装signalwire-c
Makefile:947: *** You must install signalwire-client-c to build mod_signalwire. Stop.
cd /usr/local/src/freeswitch
git clone https://github.com/signalwire/signalwire-c.git
cd signalwire-c
cmake .
make
sudo make install
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig:${PKG_CONFIG_PATH}
sudo ldconfig
ln -sf /usr/local/lib64/pkgconfig/signalwire_client.pc /usr/lib64/pkgconfig/signalwire_client.pc或者
# signalwire
git clone https://github.com/signalwire/signalwire-c.git
cd signalwire-c
/usr/local/bin/cmake .
make
sudo make install
cp /usr/local/lib/pkgconfig/*.pc /usr/lib/pkgconfig/
cp -f /usr/local/lib/* /usr/lib64/4.11、其他
- 报错让你安装libmpg123-dev，只需yum install mpg123-devel；
- 报错让你安装libmp3lame-dev，只需yum install lame-devel；
- 报错说缺少libshout3-dev，只需yum install libshout-devel等
关于声音文件安装。如果服务器能连外网，就很方便了，在源代码目录中执行：
make sounds-install
make moh-install
如果你的服务器不能连外网的话，可能还要手动下载声音文件并解压，然后放在/usr/local/freeswitch/sounds路径下。本人下载的是这两个(建议下载默认的8Khz语音文件)：
GitHub - freeswitch/freeswitch-sounds
五、验证
freeswitch安装完成之后，下一步就是启动freeswitch并验证可用性了。
首先
1. 启动freeswitch
cd /usr/local/freeswitch/bin
./freeswitch -nonat
