Hello,

We have a custom RFNOC block that we have created. When we using
GNURadio/Python everything works fine. When follow the examples in
uhd/host/examples and generate an executable using C++, we get an error on
execution.

We noticed that on start up the python program has no issue locating
controllers for all our custom blocks (FreqMod):

But when we run uhd_usrp_probe or our program we get:

The error we receive is directly related to the above. Please advise.

Thank you,
