This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
Problems against new openssl. Have opened a thread upstream. http://activemq.2283324.n4.nabble.com/activemq-cpp-3-9-4-fails-to-build-fedora-rawhide-openssl-1-1-0e-related-td4724037.html
Checked, no change in status.
