下载编译相关库
吾全部编译，signalwire编译不通过，所以禁止了。其他需要的如下：
zlib-1.2.11 yasm-1.3.0 nasm-2.14.02 tiff-4.1.0 jpeg-9d png openssl-OpenSSL_1_1_1g libssh2-1.9.0 pcre-8.44 sqlite-autoconf-3310100 curl-7.70.0 ldns-1.7.1 libuuid-1.0.3 libvpx-1.8.2 speex-1.2.0 speexdsp-1.2.0 x264-snapshot-20180101-2245-stable openh264-master libav-12.3 lua-5.3.5 opus-1.3.1 ncurses-6.1 readline-7.0 postgresql-12.3 libsndfile-1.0.28
吾博文中都提供了相应的下载及编译办法。有的只能编译到系统目录下。
编译完成之后，在PATH中加入其bin目录。
下载代码
# git clone https://github.com/signalwire/freeswitch # 建议下载发布版本的代码包 # https://github.com/signalwire/freeswitch/releases ./bootstrap.sh
git获得最新代码，如果编译不过，下载release的代码包，解压后编译。
