错误:字段“ctx”不完整类型EVP_CIPHER_CTX

Question

问题:我需要将tts引擎安装到运行Debian 8的Freeswitch中。Freeswitch已经启动并运行，但我需要从源代码构建它，以便它创建mod_cepstral模块。

当我运行make时，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:
./crypto/include/aes_icm_ossl.h:66:20: 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

我一直在互联网上寻找解决方案，但我不是开发人员，这已经超出了我的想象。任何帮助都将不胜感激。

Answer 1

在反星系团的支持下，我们确定Jessie (Debian 8)还没有完全兼容。我用Debian 7重建了服务器，现在运行良好。

Answer 2

因为更新的OpenSSL不公开结构EVP_CIPHER_CTX，

尝尝这个

EVP_CIPHER_CTX *ctx = EVP_CIPHER_CTX_new();
EVP_CIPHER_CTX_init(ctx);
//do sth here
//...
EVP_CIPHER_CTX_free(ctx);

Answer 3

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
