Compile error: 'zmq_event_t' has no member named 'data'

[mfelicio]

Hi,

First of all, I'd like to thank you for the nice work you've done.

I'm trying to use the api but it is not compiling on my machine (ubuntu). I cloned libzmq repository and built it, which means I'm running libzmq 3.2.

This error is thrown in the C function get_event declared on zmq3.go

Best regards,
Manuel Felício

What version of libzmq exactly are you using? You can find this in zmq.h. Look for these three defines:

#define ZMQ_VERSION_MAJOR 3
#define ZMQ_VERSION_MINOR 2
#define ZMQ_VERSION_PATCH 2

I searched for zmq.h on my whole file system and found these:

On /usr/local/include I have a zmq.h which says 3.3.0
On /usr/include I have a zmq.h which says 2.1.11

I think this is related to this:

zeromq/libzmq@21eeb03

They've changed the event_t structure.

It seems the implementation of socket events is in a state of flux. I will wait with a fix until the official release of zmq version 3.3. For now, use zmq version 3.2.2, that is the latest stable version. You can download it at http://www.zeromq.org/intro:get-the-software

Hi again,

Makes sense to support only the latest stable version, but I thought it was v 3.3 though.

I just downloaded 3.2.2, installed and everything works fine now.

Thank you

I fixed this in branch "v3.3".

I won't merge this into branch "master" until the stable release of ZeroMQ version 3.3.

It seems there won't be a ZeroMQ version 3.3. It goes straight from 3.2 to 4.0.
This requires a new Go binding. See: https://github.com/pebbe/zmq4
