Hi Fred - In the top-level BUILD directory there will be a file "CMakeCache.txt" where you can track down the exact variable names you need to use for including the GR CMake variables. I think these are consistent between different GR versions, but I really don't recall any longer & I'm not famility with GR 3.9's CMake -- just up through GR 3.8. In that file you can search for "GNURADIO_BLOCKS" and you'll see the "INCLUDE_DIR" or "INCLUDE_DIRS" and "LIBRARIES" or "LIBRARY" and others. You then use the correct CMake commands in your OOT to use those variables. If you're using GR's modtool to create the OOT those commands should be added automatically. Sorry I can't be more precise ... I don't have the info in front of me, but I know that the above is what I would do so that's easy to write :) - MLD

Anyone could give an example of CMakeList that use uhd and gnuradio module please ?

Thanks.

Sorry I would like to say 3.7.11.

If I have understand I need to add ${GNURADIO_BLOCKS_INCLUDE_DIRS} in my CMakeFiles that's all ?

Thank you very much for your help.

Regards.

Hi Fred,

indeed, your link_directories need to include the BLOCKS library, not just RUNTIME, when you're linking against any code in gr::blocks.

I might be a bit behind on current GNU Radio developments, but GNU Radio 3.11 isn't even in development yet, far as I can tell. Is it possible you're referring to 3.10.0.git?

Best regards,
Marcus
