如何在Mac OS X中连接JPL与SWI-Prolog [英] How to connect JPL with SWI-Prolog in Mac OS X

问题描述

你好我有一个jpl接口的问题。我想连接JPL与安装mac-ports与eclipse的swi-prolog。我有一个jpl.jar，我已经尝试导入jar文件在eclipse与构建路径，但我有这个错误：no jpl在java.library.path。
所以我已经将libjpl.dylib复制到/opt/local/lib/swipl-7.1.29/bin/中，当我执行代码时，我有这个错误：线程中的异常mainjava.lang。 notatisfiedLinkError：/opt/local/lib/swipl-7.1.29/bin/libjpl.dylib：dlopen（/opt/local/lib/swipl-7.1.29/bin/libjpl.dylib，1）：库未加载：/用户/ janw / stable / lib / swipl / lib / x86_64-darwin13.0.0 / libswipl.dylib
引用自：/opt/local/lib/swipl-7.1.29/bin/libjpl.dylib
原因：图像未找到

解决方案

经过一段时间的浪费，我找到了解决方案。
首先，它完全需要通过macports安装swi-prolog，如果没有，就像我一样，当你指向

Djava.library.path = / users / rivax / Applications / SWI-Prolog.app / Contents / swipl / lib / x86_64-darwin13.0.0

这个异常将在

线程main中的异常java.lang.UnsatisfiedLinkError：/ Users / rivax / Applications / SWI- Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0/libjpl.dylib：dlopen（/Users/rivax/Applications/SWI-Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0/libjpl.dylib ，1）：库未加载：/Users/janw/stable/lib/swipl/lib/x86_64-darwin13.0.0/libswipl.dylib

Java结果：1

所以按照这些步骤。

1. 在终端上安装swi-prolog，如果你没有安装已经有macports命令没有找到，那么请去 https://www.macports.org/install.php 和我nstall macports。


2. 导航到我的
   /opt/local/lib/swipl-6.6.6/lib的swi prolog macports安装路径/x86_64-darwin14.0.0


3. 复制此路径，并在Java VM中的java.library.path中设置为 -Djava.library .path = / opt / local / lib / swipl-6.6.6 / lib / x86_64-darwin14.0.0

现在.pl与jpl.jar将能够执行，咨询将运行。

希望它能帮助你和每个找到这个地狱问题的人。

坦白说。

Hi i have a problem with a jpl interface. I want connect JPL with swi-prolog installed with mac-ports with eclipse. I have a jpl.jar and i have tried to import the jar file in eclipse with build path but i have this error: "no jpl in java.library.path". So i have copied libjpl.dylib in a /opt/local/lib/swipl-7.1.29/bin/ and when i execute the code i have this error: "Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/local/lib/swipl-7.1.29/bin/libjpl.dylib: dlopen(/opt/local/lib/swipl-7.1.29/bin/libjpl.dylib, 1): Library not loaded: /Users/janw/stable/lib/swipl/lib/x86_64-darwin13.0.0/libswipl.dylib Referenced from: /opt/local/lib/swipl-7.1.29/bin/libjpl.dylib Reason: image not found"

解决方案

After a anoying waste of time i found the solution about that problem. First of all, its completely necesary to install swi-prolog via macports, if not, as i did, when you point in the

Djava.library.path=/users/rivax/Applications/SWI-Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0

this exception will apear

Exception in thread "main" java.lang.UnsatisfiedLinkError: /Users/rivax/Applications/SWI-Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0/libjpl.dylib: dlopen(/Users/rivax/Applications/SWI-Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0/libjpl.dylib, 1): Library not loaded: /Users/janw/stable/lib/swipl/lib/x86_64-darwin13.0.0/libswipl.dylib Referenced from: /Users/rivax/Applications/SWI-Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0/libjpl.dylib Reason: image not found at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1965) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1890) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1880) at java.lang.Runtime.loadLibrary0(Runtime.java:849) at java.lang.System.loadLibrary(System.java:1088) at jpl.JPL.loadNativeLibrary(JPL.java:100) at jpl.fli.Prolog.<clinit>(Prolog.java:85) at jpl.Query.open(Query.java:286) at jpl.Util.textToTerm(Util.java:162) at jpl.Query.<init>(Query.java:198) at consultasProlog.Consultas.consultaFicheroProlog(Consultas.java:19) at utilidades.RellenarModelo.ejecutarArchivo(RellenarModelo.java:30) at javaprolog.JavaProlog.main(JavaProlog.java:30) Java Result: 1

So follow these steps.

1. port install swi-prolog on terminal , if you dont have install already macports command not found will apear so go to https://www.macports.org/install.php and install macports.
2. navigate to the path of swi prolog macports installation which mine is /opt/local/lib/swipl-6.6.6/lib/x86_64-darwin14.0.0
3. copy this path and set in java.library.path in the java VM as -Djava.library.path=/opt/local/lib/swipl-6.6.6/lib/x86_64-darwin14.0.0

Now .pl with jpl.jar will be able to execute and the consults will run.

Hope it will help you and every person who find this hell problem.

Cheers frank.
