I am trying to Compile Speex for Android using android-NDK, currently I am targetting android 2.3.3 however later I will have to test my app on all the android versions greater than 1.6. My Android.mk file looks like:-

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := libspeex
LOCAL_CFLAGS = -DFLOATING_POINT -DUSE_KISS_FFT -DEXPORT="" -UHAVE_CONFIG_H
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog

LOCAL_SRC_FILES := \
./libspeex/bits.c \
./libspeex/buffer.c \
./libspeex/cb_search.c \
./libspeex/exc_10_16_table.c \
./libspeex/exc_10_32_table.c \
./libspeex/exc_20_32_table.c \
./libspeex/exc_5_256_table.c \
./libspeex/exc_5_64_table.c \
./libspeex/exc_8_128_table.c \
./libspeex/fftwrap.c \
./libspeex/filterbank.c \
./libspeex/filters.c \
./libspeex/gain_table.c \
./libspeex/gain_table_lbr.c \
./libspeex/hexc_10_32_table.c \
./libspeex/hexc_table.c \
./libspeex/high_lsp_tables.c \
./libspeex/jitter.c \
./libspeex/kiss_fft.c \
./libspeex/kiss_fftr.c \
./libspeex/lpc.c \
./libspeex/lsp.c \
./libspeex/lsp_tables_nb.c \
./libspeex/ltp.c \
./libspeex/mdf.c \
./libspeex/modes.c \
./libspeex/modes_wb.c \
./libspeex/nb_celp.c \
./libspeex/preprocess.c \
./libspeex/quant_lsp.c \
./libspeex/resample.c \
./libspeex/sb_celp.c \
./libspeex/scal.c \
./libspeex/smallft.c \
./libspeex/speex.c \
./libspeex/speex_callbacks.c \
./libspeex/speex_header.c \
./libspeex/stereo.c \
./libspeex/vbr.c \
./libspeex/vq.c \
./libspeex/window.c \
./ native.c \


include $(BUILD_SHARED_LIBRARY)

The problem is at some point of my code I require FLOATING_POINT configuration, however the code only works if I change it to FIXED_POINT otherwise the threads don't get CPU cycles as they should(the one thread eats most of the CPU cycles i.e. the program hangs in the floating arithmetic inside that thread) How I can make FLOATING_POINT work for me ?

  • what's the problem with floating point? I've compiled libspeex with standalone ndk (with float) – sherpya Apr 03 '12 at 08:19
  • Encoder Thread eats all the time.... and Decoder Thread doesn't get time – Amit Apr 03 '12 at 11:49
  • try adding `-mfpu=vfp -mfloat-abi=softfp` to `CFLAGS` or options for armv7 and/or neon – sherpya Apr 09 '12 at 20:10
  • Tried everything but nothing worked so I started working with FIXED_POINT configuration, It is at least working good so far... – Amit Apr 10 '12 at 04:43
