Turns out this error doesn't mean anything, my script executes just fine.

Thank you for the reply. This is my first GNU Radio application, and typing 'make test' at the Windows command line does nothing. I followed the Ettus installation instructions for installing GNU Radio and UHD, and I cannot find anything anywhere about "make" with Windows. I found some other instances of people having issues like mine, but they seem to have been related to wxPython prior to GNU Radio 3.7 (which is what I have).

Anyone have any other ideas as to how to remedy this situation, including running some other application to get things set up?

Thank you.

This file is created the first time you try to run GNU Radio, so not
during build or even install. It /will/ get created when you run 'make
test' or any other GNU Radio application.

Is this on Windows? I'm honestly not sure what the right factory
function is for Windows, but my guess is this file should contain:


Note that that's just one line, no carriage return or anything else.
