Java error no lwjgl64 in path?
提问by Ultrabyte
I'm trying to make a game and it runs fine in eclipse, but I get this error when I export and run it as a jar file.
我正在尝试制作一个游戏并且它在 eclipse 中运行良好，但是当我将它导出并作为 jar 文件运行时出现此错误。

I have tried so many things. I set the natives location to the native folder and I checked inside and lwjgl64 is in there. Any help?
我已经尝试了很多东西。我将 natives 位置设置为 native 文件夹，然后检查内部，lwjgl64 就在那里。有什么帮助吗？

This means that you do not have the native library named "lwjgl64" in a place so that Java can find and load it, or that you are using a 32-bit JVM and you are trying to load a 64-bit native library (or vice versa) - if you want to use native libraries, they must have the same "bitness" as the JVM you are using.
这意味着您在某个地方没有名为“lwjgl64”的本机库，以便 Java 可以找到并加载它，或者您正在使用 32 位 JVM 并且您正在尝试加载 64 位本机库（或反之亦然） - 如果您想使用本机库，它们必须与您使用的 JVM 具有相同的“位数”。
On Windows, the native library would be in a file lwjgl64.dll; on Mac OS X or other Unix-like systems it would be lwjgl64.so. Find this file, and then set the system property java.library.pathusing the -Doption when you start your program, for example:
在 Windows 上，本机库将在一个文件中lwjgl64.dll；在 Mac OS X 或其他类 Unix 系统上，它将是lwjgl64.so. 找到此文件，然后在启动程序时java.library.path使用该-D选项设置系统属性，例如：
java -Djava.library.path=C:\MyProject\lib com.mypackage.MyProgram
where C:\MyProject\libwould be the directory that contains the DLL.
C:\MyProject\lib包含 DLL 的目录在哪里。

LWJGL uses its own variables for the path to the native libraries:
LWJGL 使用自己的变量作为本地库的路径：
System.setProperty("org.lwjgl.librarypath", new File("pathToNatives").getAbsolutePath());
If you kept the file structure from the LWJGL package you can use something like this:
如果您保留了 LWJGL 包中的文件结构，您可以使用以下内容：
switch(LWJGLUtil.getPlatform())
{
case LWJGLUtil.PLATFORM_WINDOWS:
{
JGLLib = new File("./native/windows/");
}
break;
case LWJGLUtil.PLATFORM_LINUX:
{
JGLLib = new File("./native/linux/");
}
break;
case LWJGLUtil.PLATFORM_MACOSX:
{
JGLLib = new File("./native/macosx/");
}
break;
}
System.setProperty("org.lwjgl.librarypath", JGLLib.getAbsolutePath());
