rxtxSerial exception on Ubuntu java.lang.UnsatisfiedLinkError

Hi everyone,

I have tried to run the Main.java file from the org.reprap project, but I am getting the following exception all the time. My machine is 64bit and I have tried to replace the RXTXcomm.jar file for a 64bit version, but this does not fix the problem.

Does anyone know how to fix this problem?

Thank you for your help in advance

Has anyone had this problem? Otherwise can someone tell me where I can find an updated instructions to setup the software? The instructions in the wiki are missing so steps for the project configuration on eclipse.

Thank you

Problem Solved. I have changed the libraries to 64bit version and that has fixed the problem.

Thanks anyway
