问题
I am attempting to build the latest version of Apache ActiveMQ-CPP, which is 3.9.4. I have built both of the required dependencies, APR and OpenSSL. For OpenSSL, this is version 1.1.0f. I am able to build all 4 of the configurations without SSL support (Debug, DebugDLL, Release, ReleaseDLL). However, attempting to build anything with SSL support results in a number of errors:

The release notes haven't mentioned anything about OpenSSL since support was added in 3.2.0. However, the README.txt file included with the ActiveMQ-CPP 3.9.4 download states:
If you wish to use the SSL Transport then you will need to have OpenSSL and its includes installed on your system. We recommend that you use version 1.0.0 or higher for best performance and security, but version from 0.9.8 are also known to work.
This StackOverflow question seems to indicate that my first error (see above) implies that OpenSSL 1.1.0 isn't supported by ActiveMQ-CPP. However, there doesn't appear to be an issue submitted on the ActiveMQ-CPP Jira site about lack of OpenSSL 1.1.0 support, and their own documentation clearly states that I should be able to use "version 1.0.0 or higher".
Does anyone know whether ActiveMQ-CPP 3.9.4 supports OpenSSL 1.1.0?
回答1:
The client doesn't support OpenSSL 1.1.0 as reported on the ActiveMQ mailing lists. I don't think anyone bothered to open an issue to that effect though.
