I am working to make a detector block in gnuradio 3.6.5.1 using gr-how
"out-of-tree module". I am stuck with an error during " gr_modtool
makexml howto_detect_ff " command.
GNU Radio module name identified: howto
Warning: This is an experimental feature. Don't expect any magic.
Searching for matching files in lib/:
Making GRC bindings for lib/howto_detect_ff_impl.cc...
Traceback (most recent call last):
File "/usr/local/bin/gr_modtool", line 41, in <module>

line 214, in read_params
params_list = _scan_param_list(make_match.end(0))
AttributeError: 'NoneType' object has no attribute 'end'
Thanks in advance,
