Hi.
While trying to make osmo-trx work in multichannel configuration I've found following: - running "./Transceiver52M/osmo-trx -m -c 2 -l INFO" works but - running "./Transceiver52M/osmo-trx -m -c 2 -l INFO -g" gives following: linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.010.000.000-release

The tests were performed with usrp B210 and rather recent uhd (see above). Is this some know error/hw incompatibility?
Here are some more details:

Could this have something to do with uhd version (UHD_003.010.000.000-release) I'm using? It seems like SIGABRT happens somewhere deep in uhd intestines.
Or maybe it's some obvious misconfiguration which I've failed to notice so far?

I reproduced the gpsdo issue on my machine. This looks like something UHD version related. I'm looking into it.

Do you have a GPSDO installed in the B210?
In either case this is a bug in UHD. I want to check that all configurations are covered.

How do I check that? Also, should adding/removing GPS antennae make any difference?

The GPSDO module is an add-on component about that is about 2cm square. It mounts in the headers directly behind the GPS antenna port. If the area is empty, there is no GPSDO. GPS antennae will only have an effect if the module is populated.
https://www.ettus.com/product/details/GPSDO-TCXO-MODULE
If the GPSDO is not present, but is selected on the osmo-trx command line anyways, the proper action is to exit gracefully or continue without using the non-existent GPSDO; error logging should be output in both cases. Currently, UHD crashes in this event, which is clearly a bug.
