1，安装依赖等
yum install -y http://files.freeswitch.org/freeswitch-release-1-8.noarch.rpm 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 wget http://files.freeswitch.org/releases/freeswitch/freeswitch-1.8.5.tar.gz tar -vzxf freeswitch-1.8.5.tar.gz cd freeswitch-1.8.5 echo $PWD ./configure -C --enable-portable-binary \ --prefix=/usr/local/freeswitch \ --with-gnu-ld --with-python --with-erlang --with-openssl \ --enable-core-odbc-support --enable-zrtp \ --enable-core-pgsql-support \ --enable-static-v8 --disable-parallel-build-v8 make make -j install make -j cd-sounds-install make -j cd-moh-install ln -sf /usr/local/freeswitch/bin/freeswitch /usr/bin/ ln -sf /usr/local/freeswitch/bin/fs_cli /usr/bin/
2，后来发现缺少libks
提醒的一点是你有可能遇到mod_signalwire 果断注释掉。
make[4]: Entering directory `/usr/local/src/freeswitch/src/mod/applications/mod_signalwire' Makefile:916: *** You must install libks to build mod_signalwire. Stop. make[4]: Leaving directory `/usr/local/src/freeswitch/src/mod/applications/mod_signalwire' make[3]: *** [mod_signalwire-all] Error 1
wget https://cmake.org/files/v3.13/cmake-3.13.3.tar.gz tar -zxvf cmake-3.13.3.tar.gz cd cmake-3.13.3 ./bootstrap gmake make install cd ../ git clone https://github.com/signalwire/libks.git cd libks cmake . make make install
3, yum install -y libatomic
/usr/bin/ld: cannot find /usr/lib64/libatomic.so.1.0.0
collect2: error: ld returned 1 exit status
