Re: [Discuss-gnuradio] gr_zeromq on MS-Windows ?

[Geof Nieboer]

I'm not at the machine at the moment, but as I recall pyzmq ends up looking for one version and gnuradio the other, so maybe I have the name error backwards.  

Either way, I will fix it in the next release, as worst case I just downgrade to the version of ZMQ that was bundled with 3.7.12.

Thank you for your reply which helped me find a (temporary at least)
solution to my problem: indeed you reminded me that we had been
streaming data from GNU Radio to a MS-Windows computer running ZeroMQ
on its GNU Radio flowgraph and that was working well last
december/january. So downgrading to 3.7.12 solved my short term problem
of getting GNU Radio+ZMQ running on MS-Windows. Unfortunately I am
not able to identify the name mismatch you state in your email: I did
find some name mismatch with vc140 sentences for the boost library but
not for ZeroMQ.

Thanks for the support,
Jean-Michel
