我有一个 Android NDK 项目在 SoundTouch 库的 NDK_Build 期间失败。

构建日志

我知道它有一个未定义的参考错误，但我不明白。RateTransposer.cpp 包括 InterpolateLinear.h

#include "InterpolateLinear.h"

这是失败的代码

#ifdef SOUNDTOUCH_INTEGER_SAMPLES
    // Notice: For integer arithmetics support only linear algorithm (due to simplest calculus)
    return new InterpolateLinearInteger; # <<<<<________________LINE 284
#else

这是我的 Android.mk 文件

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/ #include/BPMDetect.h include/FIFOSampleBuffer.h include/FIFOSamplePipe.h include/SoundTouch.h include/STTypes.h

LOCAL_CFLAGS += -Wall -fvisibility=hidden -I include -D ST_NO_EXCEPTION_HANDLING -fdata-sections -ffunction-sections -marm

include $(BUILD_SHARED_LIBRARY)

谢谢你的帮助，乔

我想通了。

我在 RateTransposer.cpp 之前添加了 'SoundTouch/InterpolateLinear.cpp \' 到我的 Android.mk 文件中......
