    3.2 安装mod_curlmod_flite

    3.2.1 配置modules.conf

    sudo vim /home/mintcode/freeswitch/modules.conf

    applications/mod_curl
    asr_tts/mod_flite
    
    3.2.2 安装libflite-devel
    $ cd libs/
    $ git clone https://freeswitch.org/stash/scm/sd/libflite.git
    $ cd libflite/
    $ ./configure  --enable-pic --disable-static --enable-shared && make
    $ sudo make install
    $ sudo cp /usr/local/lib/pkgconfig/flite.pc /usr/lib64/pkgconfig

    1. continue默认把它设置为false,设为true表示FS在当前分机号的所有action都解析成功是否继续。
    2. break表示判断后的行为,有以下值:

    On-true:第一次匹配后停止查找 <br />
    On-false:默认值,第一次失败后停止查找 <br />
    Always:不管匹配与否都停止 <br />
    Never: 无论匹配与否都继续查找 <br />

      • jaychuo:有点迷糊,1.7和上面是什么关系?是不是只要做1.7的话上面6点就不用做了,或者是不是如果用1.6.6版本的话可以不做1.7这点?
      • 暴走大牙:你好,关于这个 新版本安装 上面的依赖包不用git到工程文件夹
        sh support-d/prereq.sh
        我查看这个脚本并没有去下载安装 1.4 代码依赖包 呢
        Jetsly:本来采用asterisk的,但是发现太难用了。还是这个比较简单
        Jetsly:你看上面的 会根据系统以及包管理的类型来安装对应的编译依赖包
