Gqrx failed to recognize device due to ABI breakage

[EL-File4138]

Fedora 38 with Gqrx install by dnf (It's dependencies will require SoapySDR).

Built and installed by the method in Wiki. Shared library built has an ABI of 0.8-3, while the SoapySDR has 0.8, thus not installed in the correct folder that SoapySDR will recognize. Manually moved the library file, SoapySDRUtils recognized it and the device:

But when launching Gqrx, it shows:

[ERROR] SoapySDR::loadModule(/usr/local/lib64/SoapySDR/modules0.8/libsdrPlaySupport.so)
  sdrplay failed ABI check: Library ABI=0.8, Module ABI=0.8-3

and thus not recognizing the device. Is there anything I've done wrong?

@EL-File4138 - I am running Fedora 38 here, however in my case I chose not to install any of the SDR related packages from the distribution, but I built everything from source.

In your case I suspect there's some overlap between the distribution packages (which typically end up under /usr) and what you built and installed from source (which you would find under /usr/local); if I understand correctly you have two versions of SoapySDR, one installed from the Fedora package and the other one built from source.

If this is the case I would remove the version installed from source (to avoid conflicts), i.e. I would run something like rm /usr/local/ib64/libSoapySDR.* /usr/local/lib64/SoapySDR/modules0.8/* /usr/local/include/SoapySDR* and so on), install the Fedora package SoapySDR-devel, and finally rebuild this module from source following the instructions here: https://github.com/pothosware/SoapySDRPlay3/wiki#building-soapy-sdr-play

@fventuri This is indeed the problem. The source build one comes from the driver install script of SDRplay, and I didn't notice that. Thanks for pointing out!
