Re: libgnuradio-runtime problem when capturing GNSS signals with HackRF and gnss-sdr

[Marcus Müller]

Hi,
the GR version you report to have installed (3.10.1) and the version of 
libgnuradio-runtime (3.10.6git) differ: I think you're trying to mix different versions of 
GNU Radio, and especially, try to load a library (libgnuradio-osmosdr.so) that was linked 
against a different version of GNU Radio with GNU Radio.

That won't work. I'm not an expert in GNSS-SDR, but in all honesty, when methodology 
requires you LD_PRELOAD a single library, you're always trying to "bend" something around; 
and unless you really meant to replace one library with another that does something 
different, that's *usually* not what you want.

So:

> We don't know what could be the problem,

Almost certainly that you are using LD_PRELOAD with a different version of GNU 
Radio.

Best regards,
Marcus
