No SoapySDR devices found on MacOS when devices are recognized

In my terminal, if I type

SoapySDRUtil --find

I can clearly see that device 3 is the ettus b200 found using soapysdr. However when I try to use hacktv/hacktvgui (I am using the captainjack build), it tells me that 'No Soapy SDR devices found.' I am on a Mac. Does this have anything to do with the fact that it is found under device 3? Technically this is a hacktv issue and not a hacktvgui, but captainjack does not allow issues to be posted. many thanks in advance

I actually haven't used SoapySDR (have no devices that can use it) but it requires a driver name to be specified. In the GUI, try entering uhd or sink into the Device options box, or at the command line use -o soapysdr:uhd or -o soapysdr:sink

[TylerKann]

Unfortunately neither of those worked

 hacktv -o soapysdr:sink -m m -f 471250000 -s 13500000 -g 0 test:colourbars

No SoapySDR devices found.

Do you have any other thoughts? I wonder if it has to do with the hardware (device 3 on Mac), or if it a simple additional command. Many thanks again.

Sorry for the delay in getting back to you. Can you try compiling this test app to see if this works?

Hi steevie,

I am too sorry for the late delay. Lot of school :(.

I cannot compile the example because of the following error:

tyler@lawn-10-91-5-232 SoapySDR.wiki % gcc -std=c99 example.c  -lSoapySDR && ./a.out            
SoapySDRDevice_make fail: SoapySDR::Device::make() no match

I tried looking into what this means and I couldnt really find any information for it on a macOS. A lot of it is for ubuntu. I would appreciate if you could give me some thoughts. Thanks!
