Well, as fried as my brain is now, I couldn’t resist one more try.
pi@macpi:~ $ ./Downloads/SdrGlut/sdrTest//sdrTest -fc 1e6 -f 0.76e6 -am -gain 1 -device 1 -set direct_samp 2
./Downloads/SdrGlut/sdrTest//sdrTest: error while loading shared libraries: libSoapySDR.so.0.6: cannot open shared object file: No such file or directory
Seems I moved from the frying pan into the fire.
Time to run away screaming…
