java - native 库，Java OpenAL 所需

Question

我正在尝试使用 Java OpenAL 库。我在导入名为 libsoft_oal.so 的 native 库时遇到问题。 Java OpenAL 依赖于 OpenAL 软实现。我尝试根据他们在 github 上的自述文件来构建它，似乎只编译了 libopenal.so 库。 Java OpenAL 已经 4 年没有更新了，所以在我看来，这个库只是被重命名了。我重命名了图书馆，但没有成功。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"); 加载库时一切都按预期进行。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);
    }
}

有没有办法在不直接修改库的情况下解决这个问题？谢谢

我已经编辑了库，现在一切正常。我还在 GitHub 上创建了一个拉取请求。
