Problem building new block


I’m a new guy to gnuradio and I’m trying to build a new C++ block. I’ve
used the
create-out-of-tree-project script (in gr-utils of gnuradio 3.3.0) and
changing the and the .cc .i .h files I successfully created
and installed two new blocks. the problem is when I wanted to add a
third block to the module. I’m getting a error on the make step which i
cannot understand.

make[2]: *** No rule to make target edetector_channelcheck_vff.lo', needed’. Stop.
make[2]: Leaving directory
/home/wssn/Pedro/gnuradio-3.3.0/gr-utils/src/python/edetector/lib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory/home/wssn/Pedro/gnuradio-3.3.0/gr-utils/src/python/edetector’
make: *** [all] Error 2

i’ve seen in the lib folder that lib folder that the two other blocks
create a .lo file but this one doesn’t. Any reason why? any ideia what
files to change so the edetector_channelcheck_vff.lo is created?

any help would be very welcome.

Sorry, it was just a typo…
sorry I really thought i already had gotten rid of them all before
