大家好！ 我在libriary WorldWind（它是NASA lib）上遇到了一些麻烦。 我在JetBrains Idea 14中用Java 8编写我的应用程序。 在Idea中，我可以成功编译和运行我的应用程序，但是当我尝试使用Maven创建jar并运行我的jar时 - 我有一个带有异常的大堆栈跟踪。 这里的堆栈跟踪：
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /tmp/jogamp_0000/file_cache/jln2853478832317459843/jln6471099643623499225/libgluegen-rt.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Thanx为您提供答案和帮助！ 它应该适用于Windows和Linux：）
答案 0 :(得分：1)
通过分析异常中的以下行，当您拥有32位库时，它看起来像平台依赖性问题，并且您尝试将其加载到64位进程中。

以下SO文件存在jogl插件问题。
/tmp/jogamp_0000/file_cache/jln2853478832317459843/jln6471099643623499225/libgluegen-rt.so
<强>解决方案： 尝试从Source
中采取以下提到的步骤Running under 64-bit Linux
Without installing the AMD64 version of JOGL you will likely see errors like Exception in thread "main" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path or Exception in thread "main" java.lang.UnsatisfiedLinkError: ~/wwj/libgluegen-rt.so: ~/wwj/libgluegen-rt.so: wrong ELF class: ELFCLASS32
To get it working:
Download the amd64 version of JOGL http://download.java.net/media/jogl/www/
Unzip the downloaded file and copy the content of the lib directory to your WWJ directory (e.g. cp jjogl-1.1.1-pre-20070511-linux-amd64/lib/* /path_to_WWJ/)
Edit run-demo.bash and replace the last line in the file with:
java -Xmx512m -Dsun.java2d.noddraw=true -Djava.library.path=. -classpath ./src:./classes:./
worldwind.jar:./jogl.jar:./gluegen-rt.jar $1
(Note: the only change is the addition of -Djava.library.path=.)
