本地库，Java需要OpenAL

我正在尝试使用Java OpenAL库。导入本地库libsoft_oal.so时遇到问题。 Java OpenAL依赖于OpenAL软实现。我试图根据他们在github上的自述文件来构建它，似乎只编译了libopenal.so库。 Java OpenAL没有更新4年，所以在我看来，库只是重新命名。我改名为图书馆，但没有运气。我认为我的库路径是正确的，我试图用java.library.path参数运行jvm，但没有运气。这里是堆栈跟踪：本地库，Java需要OpenAL

Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'soft_oal': libsoft_oal.so: cannot open shared object file: No such file or directory

当我加载具有的System.loadLibrary（ “soft_oal”）的文库; everythinkg按预期工作。这是在库中的问题部分：

public class ALFactory { 
    private static final String DEFAULT_DLL_NAME = "soft_oal"; 

    public final AL al; 
    public final ALC alc; 
    public final ALExt alext; 

    public ALFactory() { 
     al = (AL) Native.loadLibrary(DEFAULT_DLL_NAME, AL.class); 
     alc = (ALC) Native.loadLibrary(DEFAULT_DLL_NAME, ALC.class); 
     alext = (ALExt) Native.loadLibrary(DEFAULT_DLL_NAME, ALExt.class); 
    } 

    public ALFactory(File dllPath) throws FileNotFoundException { 
     String dllName = DEFAULT_DLL_NAME; 
     if (dllPath != null) { 
      if (!dllPath.exists()) { 
       throw new FileNotFoundException(dllPath.getAbsolutePath()); 
      } 
      System.setProperty("jna.library.path", dllPath.getParent()); 
      dllName = dllPath.getName(); 
     } 

     al = (AL) Native.loadLibrary(dllName, AL.class); 
     alc = (ALC) Native.loadLibrary(dllName, ALC.class); 
     alext = (ALExt) Native.loadLibrary(dllName, ALExt.class); 
    } 
}

有没有办法解决这个问题，而不直接修改库的方法吗？谢谢

我编辑过图书馆，现在一切正常。我也在GitHub上创建了一个pull请求。
