Hi Tom,
ORC is a Tool that is used in VOLK to optimize some kernels. Though,
this is an optional dependency. ORC kernels are not built if liborc etc
is not found.
I assume you can run example flowgraphs in GRC.
In this case, you shouldn't need to worry about ORC at all. Though,
somehow you try to link against it. Maybe it's worth a try to figure out
how ORC ends up in your `target_link_libraries`?
I know, you fixed your issue by installing liborc*-dev but this should
not be necessary.
Cheers
Johannes

Hi Marcus, Vasil. I have no idea what liborc is, nor why it is needed.
It is suggested by the make failure for the ported OOT module.
Focal Fossa had liborc-0.4 but not liborc-0.4-dev, so installed that
and make completed successfully. Thanks for the suggestion Vasil.
Perhaps it's a dependency that is missing when installing grc on 20.04?
With that, gr-hpsdr installed successfully on gr3.8, and the module
instantiates
in the flowgraph. Now to start testing to see if it works...

Hi Tom,
nice hearing from you! I didn't know that hpsdr needed orc?
Best regards,
