Re: R: Re: Gnuradio / Ubuntu 20.10

[Marcus Müller]

Hi Ralf,

it's not about the version of gr-osmosdr – the gr-osmosdr you use just has to 
be linked
against exactly the ABI version of the GNU Radio you intend to run :)
Debian, and thus Ubuntu, and thus Mint, do ship a gr-osmosdr, which is built 
against their
build of GNU Radio; that's why linux distros are cool: they make sure that 
different
pieces of software (e.g. gr-osmosdr) using different libraries (e.g. GNU Radio) 
"just
work", by offering "coherent" builds.

So, when you use a different GNU Radio than the one shipped by your Distro, you 
need to
then make sure all software using (i.e. linking against) that software is 
manually built
against this your "non-distro" version – exactly what you're observing :)

Best regards,
Marcus
