Illegal instruction (core dump) for CubicSDR + SDRplay + Artful 17.10

Postby kg5qvw » Sat Feb 10, 2018 5:12 pm

Symptom: On CubicSDR running from console on Artful 17.10 Lubuntu (32-bit Thinkpad T43) that sees the SDRplay and is receiving OK ---> use the mouse to move the frequency in either the main window or fine-tuning window ---> results in crash and console says "Illegal instruction (core dump) "

CubicSDR was compiled according to SDRplay Non-windows Workflow page (see bottom) EXCEPT the build failed on liquid-dsp for 'make' because of this line:
CFLAGS="-march=native -O3" ./configure --enable-fftoverride

HOWEVER, little googling gave this fix:

see https://github.com/jgaeddert/liquid-dsp/issues/66
where specifically this link says:

edit the makefile
change the CONFIG_CFLAGS line and add -msse3 (CONFIG_CFLAGS = -g -O2 -msse3)
save the file and NOT rerun ./configure
run make (now will work)


I was able to start CubicSDR and it saw my SDRplay and started just fine.
However, when I move the frequency cursor in either window, we get a crash and it leaves behind: "Illegal instruction (core dump)" in the console.
Space bar/keyboard entry of frequency works OK.

Anybody else have this problem or have any ideas to investigate?

Thanks!
