[SOLVED] error: field 'ctx' has incomplete type EVP_CIPHER_CTX

Issue

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,
                 from ./crypto/include/crypto_kernel.h:50,
                 from ./include/srtp.h:53,
                 from srtp/srtp.c:46:

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

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.

Solution

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.
