Just FYI, I tried the latest VOLK with your patch, but that doesn't help
if VOLK is built with ORC. It looks like libvolk.so is required by
libgnuradio-runtime.so (there's one volk_get_alignment() call in
gnuradio-runtime) and libvolk.so requires liborc-0.4.so.

Hi Johannes, Ron,
The liborc-0.4.so gets linked because it is in INTERFACE_LINK_LIBRARIES in
VolkTargets.cmake. This should be fixed in
https://github.com/gnuradio/volk/pull/367 but a volk version with this fix is
still not released.
Cheers,
Vasil

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

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,
