Having issues in adding gr-dpd in GNU Radio

[afzalmkhan]

Hi,

I am trying to add the gr-dpd block in GNU Radio version 3.8.4.0-rc1 but when I ran example grc's after installation I am getting following errors such as:

elf.dpd_gain_phase_calibrate_0 = dpd.gain_phase_calibrate()
AttributeError: module 'dpd' has no attribute 'gain_phase_calibrate'
Exception ignored in:
SystemError: returned a result with an error set

I have already installed all dependencies which is GNU radio version is 3.8.4.0-rc1, Armadello ubuntu 18.04 package, cmake version is 3.25 and gcc version is 7.5.

My GNU Radio is installed at custom directory and I have specified the prefix-3.8 path using the DCMAKE_INSTALL_PREFIX and I can see the dpd related directories in that path.

Please let me know what mistake I am making.

Regards,
