Hii

After the following command :

gr-digital % gr_modtool add -t general ofdm_chanestMMSE_vcvc

and editing the files:  include/.h , lib/.h , lib/.cc and python/digital/qa_ofdm_chanest_vcvc.py

I run the command
gr-digital % mkdir build 

gr-digital % cmake ../

It giving the following output :

Monika,

please make sure you've gone through the tutorials at
http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials, to
make sure we're speaking the same terminology and all the basics are clear.

Cheers,
