Solved!

The issue was the location of my header file for the class under test 
(Related_Clocks); it was inside the lib/ directory instead of the 
include/OOTM_NAME/ directory.

The class was able to compile when both the .cc and the .h file were located in 
the lib/ directory. However, for CMake to perform the correct linking during 
"make", the header file needs to be located in include/OOTM_NAME/ (along with 
the public api header files for the OOTM blocks). The class declaration also 
needs to include the OOTM_MODULE_API prefix as shown below:

>From gr-time_triggers/include/time_triggers/Related_Clocks.h:

#include <time_triggers/api.h>
namespace gr {
    namespace  time_triggers {
        class TIME_TRIGGERS_API Related_Clocks { [...]

Hi Jeff - I can run the zeromq_pushpull.grcvfrom gnuradio3.8 examples 
without any warnings using version 3.8.2.0-73-g4a84443c, Python 3.7.3 
under Debian 10 (or buster.)

The gnuradio-3.8 install was a clean install.

-- Cinaed


I can run  zmpq
