Hi Abhishek, your _impl.cc is using old-style naming in out-of-tree-modules and their components, whilst your detect_ff.h uses the consistent new way. I think this could be the result of using gr_modtool to generate the module skeleton, and then copy/pasting over lines from a pre-3.7 code example. Is that possible?
Also, I already pointed you to the newer guided tutorials[1], which don't build on the unmaintained gr-howto example. Please use these to get used to GNU Radio.
