问题描述

我试图编译Soundtouch库的Andr​​oid NDK。我成功安装了Cygwin和呷需要Soundtouch库。当我尝试运行NDK-build.cmd，我得到一个错误

I am trying to compile Soundtouch library with Android NDK. I successfully installed Cygwin and SWIG required for Soundtouch library. When I try to run ndk-build.cmd, i am getting an error

此问题发生与wrapper_wrap.cpp以下块：

This issue happens with the following block of wrapper_wrap.cpp :

  SWIGEXPORT void JNICALL Java_com_talkingyeti_jni2_wrapperJNI_SoundTouch_1putSamples(JNIEnv *jenv, jclass jcls, jlong jarg1, jobject jarg1_, jlong jarg2, jlong jarg3) {
  soundtouch::SoundTouch *arg1 = (soundtouch::SoundTouch *) 0 ;
  SAMPLETYPE *arg2 = (SAMPLETYPE *) 0 ;
  uint arg3 ;
  uint *argp3 ;

  (void)jenv;
  (void)jcls;
  (void)jarg1_;
  arg1 = *(soundtouch::SoundTouch **)&jarg1; 
  arg2 = *(SAMPLETYPE **)&jarg2; 
  argp3 = *(uint **)&jarg3; 
  if (!argp3) {
    SWIG_JavaThrowException(jenv, SWIG_JavaNullPointerException, "Attempt to dereference null uint");
    return ;
  }

请给我建议所有的变化，我需要什么做的SAMPLETYPE正确地编译NDK并生成SO文件。

Please suggest me what all changes I need to make on the SAMPLETYPE to compile NDK properly and to generate SO file.

推荐答案

这似乎你错过了一个头。请确保您有：

It's seem you missed a header. Make sure you have:

#include "soundtouch/include/SoundTouch.h"

和

using namespace soundtouch;
