hey happy easter....:) I generated module using gr-modtool as shown in " https://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules"; latter, as gsl_matrix , gsl_vector and gsl_linalg were required for my code I installed libgsl0-dev and all its related file through sudo apt-get install....:) Thanks in advance, Abhishek
