java.lang.UnsatisfiedLinkError: java.library.path中没有jhdf5

Question

在运行一个保存和加载h5文件的ScalaAndle1.3.4应用程序时，我得到了上述错误。

我已经尝试过配置以下内容(Win64)，但没有成功：

• -Djava.library.path=C:\Dev\Tools\HDF5\1.10.0\lib\
• -Djava.library.path=C:\Dev\Tools\HDF5\1.10.0\lib\jarhdf5-1.10.0.jar
• -Dnative.libpath.jhdf5=C:\Dev\Tools\HDF5\1.10.0\lib\hdf5_java.dll
• -Dnative.libpath=C:\Dev\Tools\HDF5\1.10.0\lib\

还有其他一些替代方案，但我仍然能找到堆栈：

Answer 1

在windows操作系统上启动二进制程序时，我也遇到了同样的问题。启动HDFView.exe后，一个命令窗口弹出，并再次关闭。

在通过CLI启动它之后，我看到了您提到的错误：

java.lang.UnsatisfiedLinkError: no jhdf5 in java.library.path

我用上面的@kaladin解决了这个问题:我将path <path to app>/HDFViewApp-3.1.2-win10_64-vs16\HDFView\app\bin添加到PATH系统环境变量。保存它之后，我重新启动了EXE文件，它像预期的那样直接工作！
