本机库，Java OpenAL 需要

Question

我正在尝试使用 Java OpenAL 库。我在导入名为 libsoft_oal.so 的本机库时遇到问题。 Java OpenAL 依赖于 OpenAL 软件实现。我试图根据他们在 github 上的自述文件构建它，但似乎只编译了 libopenal.so 库。 Java OpenAL 已经 4 年没有更新了，所以在我看来，这个库只是简单地重命名了。我重命名了图书馆但没有运气。我认为我的库路径是正确的，我尝试使用 java.library.path 参数运行 jvm 但没有成功。这是堆栈跟踪：

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
    at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:169)

    at defaultpackage.SoundTest.main(SoundTest.java:17)
:run FAILED

FAILURE: Build failed with an exception.

当我使用 System.loadLibrary("soft_oal") 加载库时； everythinkg 按预期工作。这是库中有问题的部分：

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);
    }
}

有没有办法不用直接修改库就可以解决这个问题？谢谢

我已经编辑了库，现在一切正常。我还在 GitHub.
