[dev65] A little help on TC65 development on Linux...

[Mikael Dich]

Thank you for your response Ivan!

In my java file had in the first place

import com.cinterion.io.*;

and I have tried to be more selective by specifying:

import com.cinterion.io.ATCommand;
import com.cinterion.io.ATCommandFailedException;

This doesn't make any diffence...

When producing the jar file I have tried to resolve the 
NoClassDefFoundError
one at at time and when I have the following jar-file:

midi at hvede$ jar tvf bin/HelloWorld.jar
      0 Thu Oct 27 15:03:46 CEST 2011 META-INF/
    318 Thu Oct 27 15:03:46 CEST 2011 META-INF/MANIFEST.MF
      0 Tue Oct 25 20:15:14 CEST 2011 HelloWorld/
   1473 Thu Oct 27 14:53:08 CEST 2011 HelloWorld/HelloWorld.class
      0 Thu Oct 27 14:52:32 CEST 2011 com/
      0 Thu Oct 27 14:52:38 CEST 2011 com/cinterion/
      0 Thu Oct 27 15:03:42 CEST 2011 com/cinterion/io/
    225 Thu Oct 27 15:01:40 CEST 2011 
com/cinterion/io/ATCommandFailedException.class
   1190 Thu Oct 27 15:02:06 CEST 2011 
com/cinterion/io/ATCommand$OutputStreamDataConnection.class
   1378 Thu Oct 27 15:03:42 CEST 2011 
com/cinterion/io/ATCommand$InputStreamDataConnection.class
   8223 Thu Oct 27 15:01:26 CEST 2011 com/cinterion/io/ATCommand.class

the error changes from java.lang.NoClassDefFoundError to:

JAVA ERROR: MIDlet initialization failed: java.lang.Error: 
UnsatisfiedLinkError: openATCommand

For me it seemes that the runtime linking in the JVM in the modem fails 
due to
lack of some (native) methods...

I have tried to grep for openATCommand i all classes of classes.zip, but 
it is only found in com/cinterion/io/ATcommand.class... (at least in 
clear text) - is there something similar to objdump for java classes?

Regards
