[openssl-dev] Build issues for demos/engines/zencod on openssl_1_0_2

[John Peck]

Hello All, 

I want to create a dynamic engine and am looking to the demos section for reference code on building, etc. 

So far I have found the demos rsaref and zencod not to compile out of the box in OpenSSL_1_0_2. I have hacked zencod to push it forward and now getting an error during the link, excerpted below. 

My question are: 

1. Is dynamic engine support stable and expected to work in openssl_1_0_2? 
2. Are there controls I need to enable to the build procedure or tool chain to get dynamic engine support/libcrypto.a in workable state? 

~/test2/openssl_1_0_2/demos/engines/zencod$ make 
...
