Hi,
*I went inside the folder *
>> cd gr-ieee-80211
*Added a new block test_block_cf to existing module gr-ieee-80211*
>> gr_modtool add test_block_cf
It added test_block_cf_impl.cc and test_block_cf_impl.h in /lib and
test_block_cf.h in /include/ieee802_11
Now I did the usual stuff in my work function, also copied
test_block_cf.h from /include/ieee802_11 to
/prefix/include/ieee802-11/gnuradio/ieee802_11
to make it a public header file. *Seems gr_modtool does not want to do this
for me. *
I also noticed that by default my namespace was *ieee802-11* which is
different from *ieee802_11* used by the author. Hence I changed *ieee802-11
*to* ieee802_11 *in all my files which were generated by gr_modtool.
Following to this I did following inside build directory of gr-ieee-80211
>> cmake -DENABLE_DOXYGEN=ON -DCMAKE_INSTALL_PREFIX=../ ../
>> make
Make throws errors as below which is related to inheritance I guess.
