SoapySDR on Fedora

[Ben Akh]

Ahoi,

I have a problem getting my LimeSDR running in gqrx via soapysdr.

My current status is that I compiled SoapySDR and LimeUtil.

Both LimeUtil --find as well as SoapySDRUtil --find="driver=lime" show the Lime as connected.

Even SoapySDRUtil --probe is able to read out all information from the Lime.

With gqrx I tried first the version supplied by fedora 25:

linux; GNU C++ version 6.2.1 20160916 (Red Hat 6.2.1-2); Boost_106000; UHD_003.010.001.000-0-unknown
Gqrx software defined radio receiver 2.5.3

And I compiled latest version from git:

linux; GNU C++ version 6.2.1 20160916 (Red Hat 6.2.1-2); Boost_106000; UHD_003.010.001.000-0-unknown
Gqrx software defined radio receiver v2.6-113-gb6d0

 However I noticed in both versions:

built-in source types: file fcd rtl rtl_tcp uhd hackrf rfspace 

Does not list soapy.

My devicestring is soapy=0,driver=lime and whatever inputrate I try to set gqrx logs: 

Failed to set RX input rate to ####

I've copied the soapysdr libs to /usr/local/lib64/ 

But even if I put this path manually into LD_LIBRARY_PATH it won't show up as a built-in source type.

Gqrx itself does not interface to any hardware drivers. It uses
gr-osmosdr for that. So you have rebuild gr-osmosdr after you build
soapysdr, then rebuild gqrx to use the new gr-osmosdr.

Please be very careful not to have multiple versions of gr-osmosdr installed.
