Hi all, We have just released Hyperscan 4.3.2 on Github - this consists of a small change to 4.3.1 that allows Hyperscan to be built against Boost 1.62. Unfortunately Boost 1.62 shipped with an issue that meant building Hyperscan failed when using this recent release of Boost. This issue has been reported upstream, and a fix submitted for future Boost releases: https://svn.boost.org/trac/boost/ticket/12558 regards, Matt.
