C++ Boost QA-tests linking issues

[David Myers]

Hello all,

 

Longtime GNU Radio user, new member to the list here.

 

I can’t get any C++ (Boost) QA tests to run in my OOTM. Specifically, I'm running into this linking error during the "make" step.

 

usr/bin/ld: CMakeFiles/time_triggers_qa_Related_Clocks.cc.dir/qa_Related_Clocks.cc.o: in function `test_add1::test_method()': qa_Related_Clocks.cc:(.text+0x4d): undefined reference to `gr::time_triggers::Related_Clocks::Related_Clocks()'

 

I'm running GNU Radio 3.8.1.0 as installed from Ubuntu 20.04 apt-get. The class being tested (Related_Clocks) has no issues compiling/linking/installing when used in blocks.

 

I’ve really been beating my head against this one, and any guidance would be greatly appreciated!

Thank you!
