Anyhow, it unexpectedly generated an xml file to import the non-block into GRC.

Is there a best way to just remove that xml file without causing other issues?

First, do a 'make uninstall' from your build directory, to remove the file from where GRC finds it.

Then, edit grc/CMakeLists.txt and remove the line that has the XML filename in it.

Finally, rerun the build (cmake, make, sudo make install, etc.).

Also when I tried to drag and drop the non-block into GRC, presumably from the default created xml file with no edits (curiosity always gets one in trouble?) GRC went to a blank screen. Of course I was able to close and restart and pick up at the last save which was fine. Okay none of that is really unexpected.

In general, gr_modtool creates XML files that need further editing before being usable in GRC; in this case, GRC didn't handle the mis-parse very well.

 

I guess there must be a reason you would have a noblock that can be added to a flowgraph?

You can create generic functions with parameters that you can set up as variables in GRC.  They aren't blocks added to the flowgraph but are still "GRC blocks".
