java.lang.UnsatisfiedLinkError: no xuggle-xuggler in java.library.path

问题

I'm using Ubuntu 11.04 and Eclipse. I installed Xuggler succesfully, I've checked the environment variables and everything related with linux in their FAQ: http://wiki.xuggle.comFrequently_Asked_Questions#What.27s_up_with_java.lang.UnsatisfiedLinkError.3F

I also set up Eclipse according to their tutorial: http://xuggle.wordpress.com/2009/01/23/how-to-write-your-first-xuggler-application-in-eclipse/

Whenever I try running any code which uses Xuggler I get the following error:

So, how to solve this?

回答1:

I got the answer/solution from the xuggler-users google group, credits to Navin Bhutada:

solve it by including the Xuggle variables before runing the netbeans like this:
export XUGGLE_HOME=/home/xyzuser/xuggler 
export PATH=$XUGGLE_HOME/lib:$XUGGLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$XUGGLE_HOME/lib:$LD_LIBRARY_PATH
/usr/share/netbeans/6.9/bin/./netbeans"

I use eclipse, so I just changed that last line, running eclipse from its folder through the command line and everything worked just fine.

Note: If I export the variables and try opening eclipse from a shortcut on my desktop it doesn't work. The shortcut point to the same file I ran from the command line

TLDR: export variables you got after installing run Eclipse from the terminal.

You just download correct Xuggle from this page based on ur os: http://xuggle.googlecode.com/svn/trunk/repo/share/java/xuggle/xuggle-xuggler/5.2/ And then extract the lib files to project home folder.

I've found that even though I may have my environment variables set correctly, explicitly including the Xuggler install dir in the java.library.path when executing saves me from that problem.

i.e. java -Djava.library.path="$XUGGLE_HOME" myExecutable
