尝试加载文件时出现JMagick错误 - UnsatisfiedLink [英] JMagick Error when trying to load a file - UnsatisfiedLink

问题描述

java.lang.UnsatisfiedLinkError：java.library.path中没有JMagick
at java.lang.ClassLoader.loadLibrary（ClassLoader.java:1754）
at java.lang.Runtime.loadLibrary0（Runtime .java：823）
在java.lang.System.loadLibrary（System.java:1045）

java.lang.UnsatisfiedLinkError: no JMagick in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1754) at java.lang.Runtime.loadLibrary0(Runtime.java:823) at java.lang.System.loadLibrary(System.java:1045)

尝试使用代码时

ImageInfo info;

    try {
      info = new ImageInfo();
      //image = new MagickImage(info);

    } catch (MagickException e) {
      logger.error(InsightsHelper.getStackTrace(e));
    }

为什么会发生这种情况？我在OSX上使用eclipse

any ideas why this is happening? I'm using eclipse on OSX

推荐答案

简单的答案是JVM正在尝试查找JMagick使用的本机库，并失败。您根本没有本地库，或者它不是JVM正在寻找的地方。

The simple answer is that the JVM is trying to find a native library used by JMagick, and failing. Either you don't have the native library at all, or it is not where the JVM is looking for it.

我从这里下载了一个osx软件包：joggame.com/software/jmagick.html运行了configure / make / make install，一切顺利。我还需要为java设置什么才能找到它？

I downloaded a package for osx from here: joggame.com/software/jmagick.html ran the configure/make/make install and all went well. What else would I have to set up for java to find it?

您需要弄清楚make install安装在哪里DLL并告诉Java在正确的位置查找它：

You need to figure out where "make install" installed the native DLL and tell Java to look for it in the right place:

• 如果要从Eclipse中启动，请按照以下步骤操作： trigoman的答案。

• If you are launching from within Eclipse, follow the procedure in trigoman's answer.

如果您是从命令行直接或通过脚本启动，那么您需要在您的选项中包含此选项（或等效的） java 命令：

If you are launching from the command line, directly or via a script, then you need to include this option (or the equivalent) in your java command:

    java -Djava.library.path=/some/folder/ .... 

请注意，这是一个JVM选项，必须在classname之前。

Note that this is a JVM option and has to go before the classname.
