Forum: GNU Radio Missing File?

Running my script, I get an error (repeated twice):

~\AppData\Roaming\.gnuradio\prefs\vmcircbuf_default_factory: Invalid
argument

I looked, and there is no 'vmcircbuf_default_factory' in the \prefs
folder
(there isn't anything in there). The Internet (GNURadio website and
GNURado
mailing list archives in addition to general Internet searches) provides
plenty of examples of 'vmcircbuf_sysv_shm, where the user is told to
update
the 'vmcircbuf_default_factory' file, but nothing relating directly to
my
problem.

Is this a file that should have been created when I installed GNURadio
and
its dependencies? Can I just create the file, and, if so, what does the
structure/format look like? Or, can someone point me to either a sample
file, or the file location somewhere else?

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:

gr::vmcircbuf_createfilemapping_factory

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

Tom:

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.

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