Error on make for libZMQ 4.0.0, references zmq_event_T, structure was removed April 28th

[Ghoughpteighbteau]

this changed happen in this commit: https://github.com/zeromq/libzmq/commit/9753de8566d335703c96160aa4e5f9c6e55208a9#diff-e81114d231ae71d13f16d1b6970abb37L353

and is in the master for libZMQ. So jzmq no longer compiles.

error:

well, even going back a commit I still get errors.

As libzmq doesn't have any tags to mark versions, is there a known commit that jzmq will compile against?

Good catch

found a commit that works, zeromq/libzmq@d4c5dc9

cppzmq, and consequently nzmqt are also failing on the build with this libZMQ 4 change. Hope it gets fixed
