Hello, I am attempting to create an OOT module called telemetry that receives messages and does printf() when the message is received. For now.
I am modeling it after your message_debug block found in gnuradio/blocks It was working fine till I actually created the message functions. It compiles and installs fine. When I run gnuradio_companion no errors. But when I execute my blocks I get this error: > Traceback (most recent call last): > File "/home/dhelm/gr-sidekiq/examples/telemetry.py", line 34, in <module> > from gnuradio import sidekiq > File > "/usr/local/lib/python3.8/dist-packages/gnuradio/sidekiq/__init__.py", line > 18, in <module> > from .sidekiq_python import * > ImportError: /usr/local/lib/libgnuradio-sidekiq.so.1.0.0: undefined > symbol: _ZTVN2gr7sidekiq14telemetry_implE > > I understand that there is some undefined symbol called, but I can't tell what it is from the name. Is there a way to find out? I ran into this issue when adding my message functions: The message_debug has functions like: *void message_debug_impl::print(const pmt::pmt_t& msg)* *void message_debug_impl::store(const pmt::pmt_t& msg)* These are defined in the *message_debug_impl.h* file. But not in the *include/gnuradio/blocks/message_debug.h* file. When I do that with my functions I get a compile time error that the functions are not defined. So I needed to add them to my *include/gnuradio/sidekiq/telemetry.h* file. Then I did bind and cmake, make, sudo make install I compiled and installed it. But when I actually run the block I get the error listed above. Any ideas? Thanks, Dave
