iirc, when I was switching to rpi2, i had to block compile NEON/armv7 stuff
(i've read somewhere, some time ago that rpi2's cpu has/had(?) problems with NEON, or was it not compatible with it?, i dunno now, also, my old compile from rpi worked okay while i couldn't compile or run(segfault) rpi2 armv7 build)
so code-wise I had to comment out in CmakeLists.txt":
-armv7 detection
- and NEON-related stuff
see if that'll fix anything. If not, I'll try to extract from CMakeCache.txt the values I've used.
