Hi, it seems that in the newest NDK the codes fail to compile. The errors were like:
AccumulatedTopHessian.s: Assembler messages:
AccumulatedTopHessian.s:28297: Error: r13 not allowed here -- `sub.w sp,r2,#80'
clang++: error: assembler command failed with exit code 1 (use -v to see invocation)
BTW, The ABI is armeabi-v7a.
