I guess you are working with JMF.
If you got a problem like this, all you have to do is:

1. Copy all .so files FROM /JMF-2.1.1e/lib/ TO /usr/lib with: sudo cp *.so /usr/lib/
   
2. Compile your code :)

Install JMF 2.1.1e in Ubuntu 9.04

1. Download JMF .bin from here, choose
2. Rename the file from .bin to .zip
3. Copy the three .jar files FROM /JMF-2.1.1e/lib/ TO /usr/lib/jvm/java-6-sun/jre/lib/ext/ with this: sudo cp *.jar /usr/lib/jvm/java-6-sun/jre/lib/ext/
4. Restart, and you got it!.
