Looking back at my notes, I was working with speex-1.21rc1 source code on the BeagleBoard XM. I used the following environment setting before make:
CFLAGS = -O3 -mfpu=neon -ftree-vectorize -ffast-math(?) -fsingle-precision-constant -mfloat-abi=hard (?) -mcpu=cortex-a8 [I probably experimented with -ffast-math and -mfloat-abi=hard but eventually left them out.] The last (working) Makefile seems to have used CFLAGS = -DFIXED_POINT -Ofast -mfpu=neon -mcpu=cortex-a8 -fsingle-precision-constant -fvisibility=hidden I can't swear this is the very best way to compile, but it was good enough for my work. If I was starting over, I would try http://www.opus-codec.org/ since Speex seems to be an orphan.
