Spurious (?) warning on startup about fairmq HOT 5 CLOSED

This happens if transport cannot find FairMQProgOptions. Please provide more detail on when this happens, or better a link to code that causes this.

from fairmq.

Is it possible that you have added some code that uses FairMQTransportFactory without giving it FairMQProgOptions?
E.g.: this should give no warning:
https://github.com/FairRootGroup/FairMQ/blob/master/test/protocols/_push_pull_multipart.cxx#L34
, while this will produce the above warning:
https://github.com/AliceO2Group/AliceO2/blob/dev/DataFormats/MemoryResources/test/testMemoryResources.cxx#L24

from fairmq.

Yes. For example https://github.com/AliceO2Group/AliceO2/blob/dev/Framework/Core/test/test_DataRelayer.cxx. Why is that a warning (which I interpret as something non fatal which should be fixed, as opposed to an INFO)? Can you change the level for that message?

from fairmq.

Changed the level to debug. Transport has meaningful defaults if no FairMQProgOptions are given. You will need to provide it if you want to change the defaults.

Thanks. That's more than reasonable, I think.
