Java本机loadlibrary无法加载库-Linux fedora25 java8

Question

我正在尝试加载在系统上编译的动态c ++库，以便在java中进行包装。 过去我可以在Windows上执行此操作，但是在这里我很难加载库。 这是代码：

import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.Pointer;

import java.io.File;

public interface libWrapper extends Library {

//  String path = "." + File.pathSeparator + "hiddenPath/lib/Dynamic";
//  System.setProperty("java.library.path", System.getProperty("java.library.path") + File.pathSeparator + path);
//      System.setProperty("java.library.path", path + File.pathSeparator
//          + System.getProperty("java.library.path"));

libWrapper INSTANCE = (libWrapper)
        Native.loadLibrary(
                "libgtengine.so",
                libWrapper.class );

Pointer FrameCstructor(String name, long parent,
        double x, double y, double z,
        double rotX, double rotY, double rotZ,
        double vX, double vY, double vZ,
        double angVx, double angVy, double angVz,
        double accX, double accY, double accZ,
        double angAccX, double angAccY, double angAccZ,
        boolean addToFramelist);
}

我试图用不同的方法指定库的位置，但没有成功：

1）指定-Djava.library.path = PATHTOLIBRARY

2）使用System.setProperty，但这没有成功，因为我无法运行代码。 我收到一个编译错误，提示它找不到功能setProperty（以及getProperty）：错误：（16，35）Java：预期

3）将libgteengine.so复制到与libWrapper类相同的文件夹中。

我怀疑我的图书馆的建筑结构错误吗？

这是我尝试使用方法1）和3）加载它时收到的错误消息

public interface libWrapper extends Library {

static String path = "." + File.pathSeparator + "/home/ycourvoisier/Documents/Development/GitLocalRepo/hydros-mathLibrary/HydrosMathLibraryCode/lib/Dynamic";
static {
    System.setProperty( "jna.library.path", path + File.pathSeparator
            + System.getProperty( "java.library.path" ) );
}


libWrapper INSTANCE = (libWrapper)
        Native.loadLibrary(
                "libgtengine.so",
                libWrapper.class );
}

建议使用系统的setProperty。 但是java返回一个非法的字符开始

这里的EDIT2是一个精简版本，应该执行相同的操作，但是也不起作用。 路径是在代码中直接指定的，因此不会混淆是否提供了路径：

public class Frame {

static {
    System.setProperty( "jna.library.path", "/home/NAME/Documents/Development/GitLocalRepo/com-hidden-java-math/src" + File.pathSeparator + System.getProperty( "jna.library.path" ) );
}

public interface libWrapper extends Library {

    libWrapper INSTANCE = (libWrapper)
            Native.loadLibrary(
                    "gtengine",
                    libWrapper.class );

    Pointer FrameCstructor(String name, long parent,

            double accX, double accY, double accZ,
            double angAccX, double angAccY, double angAccZ,
            boolean addToFramelist);
}

private Pointer ptrToCFrame;

public Frame(String name, int parent,
        double x, double y, double z,
        double rotX, double rotY, double rotZ,
        double vX, double vY, double vZ,
        double angVx, double angVy, double angVz,
        double accX, double accY, double accZ,
        double angAccX, double angAccY, double angAccZ,
        boolean addToFramelist) {

    ptrToCFrame = libWrapper.INSTANCE.FrameCstructor( name, parent,

Answer 1

确保将文件放在LD_LIBRARY_PATH上。

在这里查看示例代码：

https://github.com/mkopsnc/keplerhacks/tree/master/jnijna

如果您决定切换到JNI，请在此处查看：

Answer 2

解决库加载问题的方法是更改​​代码（这里我仍然怀疑执行此操作的正确方法）

public class Frame {

static {
    System.loadLibrary( "gtengine" );
}

public static native Pointer FrameCstructor(String name, long parent,
        double x, double y, double z,
        double rotX, double rotY, double rotZ,
        double vX, double vY, double vZ,
        double angVx, double angVy, double angVz,
        double accX, double accY, double accZ,
        double angAccX, double angAccY, double angAccZ,
        boolean addToFramelist);

private Pointer ptrToCFrame;

public Frame(String name, int parent,
        double x, double y, double z,
        double rotX, double rotY, double rotZ,
        double vX, double vY, double vZ,
        double angVx, double angVy, double angVz,
        double accX, double accY, double accZ,
        double angAccX, double angAccY, double angAccZ,
        boolean addToFramelist) {

    System.out.println("library: " + System.getProperty( "java.library.path" ));

    ptrToCFrame = FrameCstructor( name, parent,
            x, y, z, rotX, rotY, rotZ,
            vX, vY, vZ, angVx, angVy, angVz,
            accX, accY, accZ, angAccX, angAccY, angAccZ,
            addToFramelist );
    }
}

而且我必须在LD_LIBRARY_PATH环境变量中指定库libgtengine.so.3.7 （而不是较短版本的libgtengine.so ）的路径。 这是在仔细阅读@mko成员提供的链接 （在视频中）后发现的。

现在，这又造成了其他困难（ UnsatisfiedLinkError未定义符号：XOpenDisplay ），我将其保留一会儿。

谢谢
