Compile errors with openssl-1.0.2n #15

Open vgottardi opened 6 years ago

vgottardi commented 6 years ago

Building the engine against openssl-1.0.2n (or 1.0.2m) generates errors. Latest commit in evp.h on 1.0.2 branch seems to be the culprit - https://github.com/openssl/openssl/commits/OpenSSL_1_0_2-stable/crypto/evp/evp.h

Looks like they're backporting functions from 1.1 that they overlooked in 1.0.2.

Does a #if OPENSSL_VERSION_NUMBER < 0x100020d0 block around those functions work?

Yes, thanks. That seems to work fine.
