Passing messages to block values?

GR 3.7.4 now has a message output on the QT GUI Frequency Sink. Is
there way
in GRC to pass this message to a value field within a block? For
instance,
pass it to the Center Frequency value in the UHD Source block to retune
the
hardware?

Is there a way to disable the frequency re-centering when the mouse is
clicked, that way I could pass the frequency to a channelizer without
altering the main spectral display.

Thanks,
Lou

Hey Lou,

not yet, but very soon it will :slight_smile:

Tom fixed that very recently. If you git pull the latest master, it
won’t do that.

Martin,

After git pull, do I have to remove the build directory and rebuild the
entire code, or can I do a:

sudo make uninstall
cmake …/
make
make test
sudo make install

to just recompile the changed files. As a general rule, say going from
3.7.3 to 3.7.4, it’s unclear to me when I should rebuild everything.

Thanks,

Nope, no need to uninstall and clean things like that. Generally, within
the same version, you can just rebuild and install. It’s between
versions
that you’d want to uninstall, clean up your build directory, and
rebuild.
But for a small change like this after updating from git, save yourself
a
lot of time and just call make:

$ git pull
$ (change to build directory)
$ make -jN (for N cores on your machine)
$ make test (optional)
$ sudo make install

Then you should be all set. If there were any changes made to
cmakefiles,
make will know that and rerun cmake for you.

Unfortunately, this time, it won’t save you a lot of time since we did
some
white space cleanup on the tree, so we touched a lot of files…
