Same error rebuilding against UHD 4.8 for conda-forge: conda-forge/soapysdr-module-uhd-feedstock#31. This looks like it is related to post_input_action / post_output_action functions being added to the rx_streamer / tx_streamer classes in UHD: EttusResearch/uhd@7833aa7. I guess the UHDSoapyRxStream / UHDSoapyTxStream classes need to implement these functions.
