Android : Help in compiling SoundTouch lib in andr

Question

I am trying to compile the SoundTouch lib with Android NDK. I got some instruction from Here to compile this lib in android.

But when I try to compile it with ndk-build command it show errors in various source files of SoundTouch lib something like this:

I tried to Switch off exception handling as mentioned in the instructions but it doesn't seems to work.

I copied all the files from SoundTouch source to JNI folder of my project. Here is my android.mk file :

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_CFLAGS :- -frtti -fexceptions

LOCAL_SRC_FILES := AAFilter.cpp BPMDetect.cpp cpu_detect_x86.cpp FIFOSampleBuffer.cpp FIRFilter.cpp main.cpp mmx_optimized.cpp PeakFinder.cpp RateTransposer.cpp RunParameters.cpp SoundTouch.cpp sse_optimized.cpp TDStretch.cpp WavFile.cpp

LOCAL_LDLIBS := -lpcap

LOCAL_MODULE := libSoundTouch

LOCAL_C_INCLUDES := BPMDetect.h FIFOSampleBuffer.h FIFOSamplePipe.h SoundTouch.h STTypes.h

include $(BUILD_SHARED_LIBRARY)

Can anyone please help me to compile and use SoundTouch lib on android?

UPDATE :

I changed my android.mk file as below

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_CPP_FEATURES += -fno-exceptions

LOCAL_SRC_FILES := \
     SoundTouch/AAFilter.cpp \
     SoundTouch/BPMDetect.cpp \
     SoundTouch/cpu_detect_x86.cpp\
      SoundTouch/FIFOSampleBuffer.cpp \
      SoundTouch/FIRFilter.cpp \
      SoundTouch/mmx_optimized.cpp \
      SoundTouch/PeakFinder.cpp \
      SoundTouch/RateTransposer.cpp \
      SoundTouch/SoundTouch.cpp \
      SoundTouch/sse_optimized.cpp \
      SoundTouch/TDStretch.cpp 

LOCAL_MODULE := libSoundTouch

LOCAL_C_INCLUDES := include/BPMDetect.h include/FIFOSampleBuffer.h include/FIFOSamplePipe.h include/SoundTouch.h include/STTypes.h

include $(BUILD_SHARED_LIBRARY)

And now its working all fine. Thank you

I have successfully compiled by changing my android.mk file :

here is my android.mk file

include $(CLEAR_VARS)
LOCAL_PATH:= $(call my-dir)

LOCAL_CPP_FEATURES += -fno-exceptions

LOCAL_SRC_FILES := \
     SoundTouch/AAFilter.cpp \
     SoundTouch/BPMDetect.cpp \
     SoundTouch/cpu_detect_x86.cpp\

Check out THIS link this guy already compiled ready to use SoundTouch Android wrapper.

• Currently capable of time-stretching and pitch shifting.
• Currently only supports Androids with an FPU (armeabi-v7a).

Example usage:

//There are currently 16 track id's you can use (0-15), each one has a separate SoundTouch processor.

    //Set your audio processing requirements: track id, channels, samplingRate, bytesPerSample, 
    //                              tempoChange (1.0 is normal speed), pitchChange (in semi-tones)

    SoundTouch soundTouch = new SoundTouch(0, 2, 44100, 2, 1.0f, 2.0f);

    //byte[] sizes are recommended to be 8192 bytes.

    //put a byte[] of PCM audio in the sound processor:
    soundTouch.putBytes(input);

    //write output to a byte[]:
    int bytesReceived = soundTouch.getBytes(output);

    //after you write the last byte[], call finish().
    soundTouch.finish();

    //now get the remaining bytes from the sound processor.
    int bytesReceived = 0;
    do
    {
        bytesReceived = soundTouch.getBytes(output);
        //do stuff with output.
    } while (bytesReceived != 0)

    //if you stop playing, call clear on the track to clear the pipeline for later use.
    soundTouch.clearBuffer()
