5 years ago Illegal instruction (core dumped) seems to designate a CPU optimization in the compiled code that is not supported by your hardware. What is the output of lscpu in your system?

5 years ago Well it does have ssse3, sse4_1 and even sse4_2 but no avx, avx2. Normally the cpu flags should be limited to sse4_1 in the debian builds but apparently somewhere it does not work. At least this gives some insight on where to look at quite possibly in the external dependencies build that may not inherit from the global flags.
If you were compiling from source (or using the Docker build) the appropriate flags should be automatically selected. But in a package build this is a one size fits all.

5 years ago Missed this one:
Jun 5 07:01:03 Computer kernel: [ 2404.256520] traps: sdrangel[9189] trap invalid opcode ip:7ff9214e1741 sp:7ffddef19ed0 error:0 in libLimeSuite.so.19.01.0[7ff9214bb000+bb000]So yes this further narrows down to LimeSuite "external" compilaton in the new build system.

5 years ago I had similar issues with consumers of libLimeSuite in openSUSE and asked the LimeSDR guys if they could add a runtime detection for their SIMD optimizations to have a proper solution for this problem... https://github.com/myriadrf/LimeSuite/issues/234
Since this request wasn't accepted by upstream you still have to compile libLimeSuite with " -DENABLE_SIMD_FLAGS="SSE3" to workaround those compatibility issues. https://build.opensuse.org/package/view_file/hardware:sdr/limesuite/limesuite.spec?expand=1

5 years ago Thanks for the tip I was wondering which option to use. In fact auto-detection in LimeSuite does not serve us right because it is going to detect the CPU features of the build server just like it does today so -DENABLE_SIMD_FLAGS="SSE3" is actually what we are looking for.
BTW this is how things are working with the new build system in SDRangel but there is a way to restrict the CPU flags to a specific level i.e. -DFORCE_SSSE3=ON or -DFORCE_SSE41=ON. In 4.9.0 I have used the SSE41 flag but I may fallback to SSSE3 in the future to be even more generic.

5 years ago Note: one can use this method to detect AVX (of all kinds) instructions: https://stackoverflow.com/questions/47878352/how-to-check-if-compiled-code-uses-sse-and-avx-instructions You need to use gawk in place of awk due to the huge size of the regexp.

5 years ago Apparently libcm256cc.so also has AVX. This should be easy to fix since cm256cc is in my realm.
Edit: exists already: -DENABLE_DISTRIBUTION=ON

5 years ago Appreciated, Edouard. All working normally again.
I've started getting this in multiple Ubuntu 18.04 systems upgraded from 4.8 that previously worked. A problem with the Limesdr plugin? I'm only using the .deb version currently.
