SDRPlay driver not recognised by SoapySDR

[g7jafParticipant]

I’m attempting to use my SDRPlay2 with CubicSDR on a Raspberry Pi 4.

I downloaded and have installed the latest SDRplay_RSP_API-RPi-2.13.1.run driver following instructions online. This process seemed to pass OK,
I see a file /usr/local/lib/libsdrplay_api.so along with a couple of other links in the same directory pointing to this file.

I then installed SoapySDR as per published procedure. Again, this seems to go OK with no error messages being reported.

The problem I have is that SoapySDR fails to find the SDRPlay driver.

SoapySDRUtil –find

returns

which seems to infer SoapySDR can’t locate the SDRPlay driver.

Running uname gives me the following response

Linux pi23 4.19.57-v7l+ #1244 SMP Thu Jul 4 18:48:07 BST 2019 armv7l GNU/Linux

Any pointers on where to look next?

did you install soapysdrplay also?

i’m running a RSP2 on a pi4 via archlinuxarm.

Yes, you’re absolutely right – this was the problem. I somehow missed it in the instructions.
I’ve now got SDRPlay working on the raspberry pi 4, connecting remotely from my Mac Pro.
Thanks for your help.
