Sooo gnuradio-runtime/lib/prefs.cc:
77 // Find if there is a ~/.gnuradio/config.conf file and add this to
78 // the end of the file list to override any preferences in the
79 // installed path config files.
80 fs::path homedir = fs::path(gr::appdata_path());
81 homedir = homedir/".gnuradio/config.conf";
82 if(fs::exists(homedir)) {
83 fnames.push_back(homedir.string());
84 }
85
This means that things in Users/youruser/Application
Data/.gnuradio/config.conf *should* be read.

Uh-oh.
Can you execute a
gnuradio-config-info --prefsdir --sysconfdir
please?
Back to topic:

I'm really not experienced Windows debugger; under Unixes, I'd do run
like (to trace all "stat" calls, ie. when the code above checks for the
existence of config.conf)
strace -e stat -o '|grep config.conf' gnuradio-config-info -v
but I really don't know whether that even works in theory under Windows.
I'm a bit worried about this line:
81 homedir = homedir/".gnuradio/config.conf";
Because it implicitly assumes that the OS considers "/" as path
separator between .gnuradio and config.conf. Boost might or might not
fix that under windows. But it's probably OK.
Best regards,
Marcus
