Problem: I need to install Cepstral (tts engine) into Freeswitch running Debian 8. Freeswitch is already up and running, but I needed to build it from source in order for it create the mod_cepstral module.
When I run make
this is the error I get:
In file included from ./crypto/include/prng.h:17:0,

I have been scouring the internet for solutions, but I am not a developer and this is way over my head. Any help would be appreciated.
cause newer OpenSSL don't expose struct EVP_CIPHER_CTX ,
try this
EVP_CIPHER_CTX *ctx = EVP_CIPHER_CTX_new();
EVP_CIPHER_CTX_init(ctx);
//do sth here
//...
EVP_CIPHER_CTX_free(ctx);
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
Get the latest version of libsrtp

It appears that there is a dependency on OpenSSL, but the version of OpenSSL you are using is incompatible. You are using OpenSSL 1.1.0 but you need to use OpenSSL 1.0.2
After talking with support at Cepstral, we determined that Jessie (Debian 8) is not yet fully compatible. I rebuilt the server with Debian 7 and it is working fine now.
