You have to add BLOCKS in addition to RUNTIME. That is, change
the existing line:
Hello Marcus,
I have added this in my main cmake: set(GR_REQUIRED_COMPONENTS
BLOCKS). Although, when I tried to compile it I got the
following message:

I would also want to mention that before my addition of the
function gr::blocks::count_bits8 I had no problem at all with
the compile process. Do you have any idea on how to fix this?
Thanks again.

Hello Tzougkarakis,
do you also link against gr-blocks? It's probably
sufficient to add "BLOCKS" to GR_REQUIRED_COMPONENTS in your
OOT's main CMakeLists.txt.
Best regards,
Marcus

Hello,
I have an OOT module which I have created with gr_modtool
and I want to use the function count_bits_8 and
count_bits_16 from gnuradio/blocks/count_bits.h. I have
included the library in my c++ file but when I try to
compile it I get the following message:

I know that it is a link error but I don't know what
addition I should do in order to fix the error. Any help
would be appreciated.
Thank you.
