问题
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:
./crypto/include/aes_icm_ossl.h:66:20: error: field ‘ctx’ has incomplete type
EVP_CIPHER_CTX ctx;
^~~
In file included from srtp/srtp.c:50:0:
./crypto/include/aes_gcm_ossl.h:58:18: error: field ‘ctx’ has incomplete type
EVP_CIPHER_CTX ctx;
^~~

make[1]: Leaving directory '/usr/src/freeswitch/libs/srtp'
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.
回答1:
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
.
回答2:
cause newer OpenSSL don't expose strcut 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);

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
回答4:
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.
