java - 重装ubuntu后JOGL不起作用

Question

我在 ubuntu 9 上用 eclipse 有一个完整的工作项目。现在我已经安装了 Ubuntu 10.10，恢复了备份，下载了 Eclipse 并尝试运行该项目。

项目文件夹根本没有改变!但现在不行了:

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path

如果我进入“项目属性> java构建路径>库”，gluegen-rt.jar和jogl.jar都存在，并且我没有编译错误(“导入javax.media.opengl.GLAutoDrawable;”没有错误，所以我认为类已正确加载)

我也尝试从 synaptic 安装 JOGL。

这里是完整的错误堆栈跟踪:

我发现了问题!

ECLIPSE 保存外部 JAR 的绝对路径

在 Eclipse 项目属性 -> Java 构建路径中，转到您的库，找到gluegen-rt.jar，展开它，然后单击“ native 库位置”并输入 JOGL 下载附带的 native 库的位置.

重新安装 ubuntu 后，我更改了我的主文件夹结构。
