什么是 LD_LIBRARY_PATH 以及如何使用它?

What is LD_LIBRARY_PATH and how to use it?(什么是 LD_LIBRARY_PATH 以及如何使用它?)

问题描述

我参与开发一个Java项目，它使用了一些C++组件，因此我需要Jacob.dll.(在 Windows 7 上)

I take part in developing a Java project, which uses some C++ components, thus I need Jacob.dll. (on Windows 7)

我不断收到 java.lang.UnsatisfiedLinkError: no JacobDB in java.library.path 无论我将 Jacob.dll 放在哪里......

I keep getting java.lang.UnsatisfiedLinkError: no JacobDB in java.library.path no matter where I put Jacob.dll....

我寻找了可能的决定，到目前为止我还没有尝试过设置 LD_LIBRARY_PATH 变量，指向 .dll 文件.

I looked for possible decisions and the one that I haven't tried so far is setting the LD_LIBRARY_PATH variable, pointing at the .dll file.

我没有什么经验，也不熟悉该变量的含义和用法 - 你能帮帮我吗?

I have little experience and I'm not familiar with what should be the meaning and usage of that variable - can you help me?

推荐答案

通常你必须在JVM的命令行上设置java.library.path:

Typically you must set java.library.path on the JVM's command line:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass
