ldconfig #动态链接库管理命令，目的让动态链接库为系统所共享
升级opus，下载opus-1.3.1安装包并进行编译安装，在/usr/local/src目录下执行
wget https://archive.mozilla.org/pub/opus/opus-1.3.1.tar.gz
tar xvfz opus-1.3.1.tar.gz
cd opus-1.3.1
./configure
make
make install
cp /usr/lib/pkgconfig/opus.* /usr/lib64/pkgconfig/
安装spandsp,不安装会报一下错误：
spandsp >= 3.0... configure: error: no usable spandsp; please install spandsp3 devel package or equivalent
git clone https://github.com/freeswitch/spandsp.git
cd spandsp
./bootstrap.sh -j
./configure
make
make install
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH}
ldconfig
安装sofia-sip,不安装会报一下错误：
sofia-sip-ua >= 1.12.12… configure: error: no usable sofia-sip; please install sofia-sip-ua devel package or equivalent
git clone https://github.com/freeswitch/sofia-sip.git
cd sofia-sip
./bootstrap.sh -j
./configure
make
make install
ldconfig
然后编译freeswitch即可，在/usr/local/src目录下执行
tar -xf freeswitch-1.10.5.-release.tar.gz
mv freeswitch-1.10.5.-release freeswitch
cd freeswitch
./configure
make
make install
如遇编译失败，clean之后重新编译即可
make clean
cd xxx_libray_duiyigndesoft
./configure
make
make install
freeswitch默认编译安装的目录在/usr/local/freeswitch：
cd /usr/local/freeswitch/bin
freeswitch -nc -nonat
或者
./freeswitch
可以根据实际需要是否建立软连接：
ln -sf /usr/local/freeswitch/bin/freeswitch /usr/local/bin/
ln -sf /usr/local/freeswitch/bin/fs_cli /usr/local/bin/
/usr/local/src/freeswitch/module.conf编译之前根据实际需要是否需要注释编译的模块：
#applications/mod_signalwire
#applications/mod_av
