Subject [jira] [Commented] (HADOOP-14597) Native compilation broken with OpenSSL-1.1.0 because EVP_CIPHER_CTX has been made opaque
Date Wed, 28 Jun 2017 00:27:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16065719#comment-16065719

Allen Wittenauer commented on HADOOP-14597:
-------------------------------------------

bq. cc 	root in the patch failed. 

That's sort of what I was expecting based upon https://wiki.openssl.org/index.php/1.1_API_Changes#Adding_forward-compatible_code_to_older_versions
.

It looks like we need to #ifdef old vs. new routines here.

> One of the primary differences between master (OpenSSL 1.1.0) and the 1.0.2 version is
that many types have been made opaque, i.e. applications are no longer allowed to look inside
the internals of the structures
