重新安装ubuntu后，JOGL不起作用 [英] JOGL does not work after reinstalling ubuntu
问题描述
项目文件夹根本没有更改！
但现在它不起作用：
线程中的异常AWT-EventQueue-0java.lang.UnsatisfiedLinkError：no在java.library.path中的gluegen-rt
如果我转到project properties> java build path> librariesgluegen-rt。 jar和jogl.jar存在，我没有编译错误（ import javax.media.opengl.GLAutoDrawable; 没有错误，所以类正确加载我认为）
我尝试从突触安装JOGL。
这里是完整的错误堆栈跟踪：

我发现问题！
ECLIPSE保存外部JAR的绝对路径
在您的eclipse项目属性 - > Java构建路径，转到您的库，找到gluegen-rt.jar，展开它，然后单击Native Library Location，然后输入JOGL下载本机库的位置。
在重新安装ubuntu后，我更改了我的主文件夹结构。
i had a fully work project in ubuntu 9 with eclipse. Now i have installed Ubuntu 10.10, get the backup back, downloaded Eclipse and try to run the project.
The project folder was not changed at all! But now it does not work:
Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path
If i go to "project properties > java build path > libraries" gluegen-rt.jar and jogl.jar are present and i have no compilation error ("import javax.media.opengl.GLAutoDrawable;" has no error so classes are loaded correctly i think)
i tried to install JOGL from synaptic too.
Here the full error stacktrace:

i found the problem!
ECLIPSE SAVE ABSOLUTE PATH OF EXTERNAL JARS
In your eclipse project properties -> Java Build Path, go to your library, find the gluegen-rt.jar, expand it, and click on Native Library Location and enter the location for the native libraries that came with your JOGL download.
after reinstallin ubuntu i changed my home folder structures.
这篇关于重新安装ubuntu后，JOGL不起作用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
