Build error: ‘zmq_event_t’ was not declared in this scope

[utgarda]

Checking out v 3.1.0, running configure:

$ git checkout v3.1.0
HEAD is now at fbc3521... [maven-release-plugin] prepare release v3.1.0
$ ./autogen.sh
...
$ ./configure
...

Ok so far, now trying make

$ make

Hm, v3.1.0 is two years old, does this problem exist on master too?

[anmonteiro]

FWIW, I'm also getting this error in the v3.1.0 tag but I solved it by cloning from this commit instead.

I also ran into this issue with v3.1.0 (wanted to build a known stable version of jzmq). Pulled master(jzmq) and compilation proceeded normally.

##编辑Event.cpp ，参考代码对比 https://github.com/zeromq/jzmq/commit/eb40d6db43ce3545e623dad6cc6721a90885b5ba 替换不然make install报错 #Event.cpp:60:5: error: 'zmq_event_t' was not declared in this scope :<<!

vim src/main/c++/Event.cpp

./autogen.sh ./configure make -j4 && sudo make install
