Hi !


I'm trying to use Neon on OpenCV 1.1 (not 2.1) library...i added the flag:  ' -mfpu=neon ' but i get this error :


my_fobj.cpp:1: error: invalid floating point option: -mfpu=neon


I'm trying to accelerate the find_obj.cpp ...this is my incomplete command line(missing all other library used) :


arm-none-linux-gnueabi-g++ -ggdb  -ftree-vectorize -ffast-math -mfpu=neon  `pkg-config --cflags opencv` -o `basename $1 .cpp` $1 -L$prefix ...(all other libraries..)


Can anyone  help me ? Am I on a wrong way ??


Thanks to everybody!
