terminate called after throwing an instance of 'Tango::DevFailed' #1086

Closed vallsv closed 4 years ago

vallsv commented 4 years ago

Hi,

I have created a very small Taurus application terminating this way.

terminate called after throwing an instance of 'Tango::DevFailed'

THis message is a guess print by Qt at the event loop termination. But i don't know.

I turn the python looging module to debug but there is nothing.

By chance do you have any idea how to debug this kind of things?

vallsv commented 4 years ago

I thought the logging config was propagated. I found i can enable the Taurus polling. But it do not help much. There is maybe other things i cna turn on?

Hi Valentin, Do you have any of the devices down? Are you using the latest taurus from develop (or at least with #1061 merged)? I used to see this kind of errors (the GUI was not even starting) when there were devices not exported, but this got fixed with #1061.

Thanks a lot. It looks to be the case. A device is not there. I still have no GUI displayed, but iv got a nice traceback. I will try to see what i can do.
