We just discovered a bug with gr_modtool in version 3.6.4 of GNU
Radio. Turns out that there is an extra comma that turns a string into
a tuple. With the new C++ implementation of the preferences handler,
this causes a bug when trying to run the ‘newmod’ tool of gr_modtool.
The patch is very simple and shown below. Make that one line (one
character, even) change and reinstall (from gr-utils, you can just run
‘sudo make install’ to do this very quickly).
Sorry for any inconvenience. We’ll get a patched version (3.6.4.1) out
soon.
