Failed safe load module error with LoRa-SDR and PothosFlow and

With Ubuntu 18.04 I get the error:

Pothos.PluginLoader.load: Plugin Module Error: Pothos::PluginModule(/usr/local/lib/Pothos/modules0.6/lora/libLoRa_Blocks.so): failed safe load

on startup of PothosFlow.

Any ideas for proceeding?

Setup:::

Clone these three repositories:

For poco and json make sure you install them so the LoRa-SDR installer can find them:

sudo cmake --build . --target install

with PothosCore installed first:

If nobody has any suggestions would try the Pothos group:

https://groups.google.com/forum/#!forum/pothos-users

May be a path issue or could be that the LoRa blocks need updating, but looks Pothos related rather than SDR hardware.
