问题：我需要将Cepstral(tts引擎)安装到运行Debian 8的Freeswitch中.Freeswitch已经启动并运行,但是我需要从源代码构建它以便创建mod_cepstral模块.

当我运行make这是我得到的错误：

In file included from ./crypto/include/prng.h:17:0,
                 from ./crypto/include/crypto_kernel.h:50,
                 from ./include/srtp.h:53,
                 from srtp/srtp.c:46:

     EVP_CIPHER_CTX ctx;
                    ^~~

Makefile:3931: recipe for target 'libs/srtp/libsrtp.la' failed
make: *** [libs/srtp/libsrtp.la] Error 2

我一直在寻找解决方案的互联网,但我不是开发人员,这是我的头脑.任何帮助,将不胜感激.

解决方法:

wget https://github.com/cisco/libsrtp/archive/v2.1.0.tar.gz
tar xfv v2.1.0.tar.gz
cd libsrtp-2.1.0
./configure --prefix=/usr --enable-openssl
make shared_library && sudo make install

获取最新版本的libsrtp.
