Building on RPi

Trying to build on RPi (ARM cpu) getting this error:

pi@raspberrypi:~/polylidar/OrganizedPointFilters/cmake-build $ cmake --build .
Built target OrganizedPointFilters
Building CXX object src/Python/CMakeFiles/organizedpointfilters.dir/organizedpointfilters_pybind/docstring/docstring.cpp.o
c++: error: unrecognized command line option ‘-msse4.2’

Obviously, SSE extension isn't available on ARM. I couldn't find where to disable this, as I only found this comment in your code ;)

Thanks!

I have an AMD cpu, zen 2 3900x. What do you have?

You can disable this here as well:

OrganizedPointFilters/src/CMakeLists.txt

Line 8 in b3b104c

    
           set(OPTIMIZATION_FLAGS "-O3 -DNDEBUG -ffast-math -funsafe-math-optimizations -msse4.2")

You will have to delete the cmake-build directory.
Let's keep this open so I can make a cross platform change that works even on arm cpus and old x86

Oh sorry I saw that you said AMD but meant ARM. Should have known from title. Nevermind the question!

Yeap, edited the original post and corrected to ARM... sorry.

I removed -msse4.2 and rebuilt on RPi. it now works!
I missed it because search "sse" or "msse" on GitHub never returned this result, only the comment I mentioned above ;(

I'll try the full monty with polylidar-realsense on the RPi in the next days, and update you.
thanks again!
