Question

运行保存和加载h5文件的Scala Saddle 1.3.4应用程序时出现上述错误。

我已经尝试过没有成功配置以下（Win64）：

-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\

以及其他一些替代方案，但我仍然得到堆栈跟踪：

Answer 1

我在 Windows 操作系统上启动二进制文件时遇到了同样的问题。启动 HDFView.exe 后会弹出一个命令窗口，然后再次关闭。

通过 CLI 启动后，我看到了您提到的错误：

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

我从上面用@kaladin anwser 解决了这个问题：我将路径 <path to app>/HDFViewApp-3.1.2-win10_64-vs16\HDFView\app\bin 添加到 PATH 系统环境变量中。保存后，我重新启动了 EXE 文件，它直接按预期工作了！

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