I installed GNU RADIO from this link http://blogs.bu.edu/mhirsch/2012/07/installing-gnu-radio-in-ubuntu-12-04-x64/comment-page-1/ I want to test some blocks & see their output to understand them more and more. for example I opened additive_scrambler_bb c++ codes in terminal to understand but I want to see how some parameters change in code when running it . how to output these parameters in terminal ? Can I write in code "cout" like any c++code? And do I have to build gnuradio again even if I will erase all my modifications in code (I don't want these modifications permanently I want only to output all parameters to understand the block)
I did the following: editing it using vim ./additive_scrambler_bb_impl.cc running it to see the output on terminal using ./additive_scrambler_bb_impl.cc but when I ran it in terminal I got this message: bash: ./additive_scrambler_bb_impl.cc: Permission denied Thanks
