Re: [Discuss-gnuradio] \"make\" error while making detector (howto_detect_ff) block.

[abhishek]

hey marcus,
here error given is, could not insert function, but we can according to 
"http://gnuradio.org/redmine/projects/gnuradio/wiki/BlocksCodingGuide#Public-Header-Files";. 
Even i am not able to get last and second last error of expected "(" and 
"{", but in the code all brackets are up to the mark and used properly.
