Seems these two OpenSSL functions: ENGINE_get_default_ECDSA() ENGINE_get_default_ECDH()
have been dropped; in util/libeay32.num: ... ENGINE_get_default_ECDH 3387 1_1_0 NOEXIST::FUNCTION: ENGINE_get_default_ECDSA 3662 1_1_0 NOEXIST::FUNCTION: ...
https://raw.githubusercontent.com/openssl/openssl/master/util/libeay.num
(not sure exactly what 'NOEXIST' does). So shouldn't common/crypto.c be patched into something like:
--- a/src/common/crypto.c 2016-01-14 22:29:59 +++ b/src/common/crypto.c 2016-01-18 17:55:53 @@ -373,8 +373,10 @@ used by Tor and the set of algorithms available in the engine */ log_engine("RSA", ENGINE_get_default_RSA()); log_engine("DH", ENGINE_get_default_DH()); +#if OPENSSL_VERSION_NUMBER < OPENSSL_V_SERIES(1,1,0) log_engine("ECDH", ENGINE_get_default_ECDH()); log_engine("ECDSA", ENGINE_get_default_ECDSA()); +#endif log_engine("RAND", ENGINE_get_default_RAND()); log_engine("RAND (which we will not use)", ENGINE_get_default_RAND()); log_engine("SHA1", ENGINE_get_digest_engine(NID_sha1));
Isn't OpenSSL 1.1.0 supported yet? Scratching head...
BTW, I'm using TDM-gcc 5.1 (http://tdm-gcc.tdragon.net/) on Win-10.
