The libs where ok, I just used the wronng CLASSPATH. :-)
But here is another problem.
[EMAIL PROTECTED]:~/eclipse/BaseStation> cat t.java
import java.io.*;
import josx.rcxcomm.*;
public class t
{
public static void main(String[] args)
{
try
{
RCXPort port = new RCXPort("usb");
}
catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}
[EMAIL PROTECTED]:~/eclipse/BaseStation> javac t.java
[EMAIL PROTECTED]:~/eclipse/BaseStation> java t
/dev/legousbtower0: not a tty
java.io.IOException: Tower open failed
at josx.rcxcomm.RCXPort.<init>(RCXPort.java:26)
at t.main(t.java:11)
[EMAIL PROTECTED]:~/eclipse/BaseStation> echo $RCXTTY
/dev/legousbtower0
[EMAIL PROTECTED]:~/eclipse/BaseStation>
It makes no difference if I set the port explicitly or not.
The isatty() check happens in ./rcxcomm/src/rcx_comm.cpp:373
But this code should not be called for USB towers because it will
just get execute if usb_flag != 1
The variable is set and defined in ./rcxcomm/src/irtower.cpp:64
with Java_josx_rcxcomm_Tower_open(JNIEnv *env, jobject obj, jstring jport).
#define TOWER_NAME "/dev/lego0"
[...]
#if defined(LINUX) || defined(linux) || defined(__APPLE__)
if ((strcmp( tty , "usb" ) == 0) ) {
usb_flag = 1;
tty = TOWER_NAME;
}
#endif
This is not like descibed in the tutorial.

6. Set the RCXTTY environment variable to your 'tower' device:
export RCXTTY=com1 or export RCXTTY=/dev/usb/legousbtower0.
Correction:
root# ln -s /dev/usb/legousbtower0/dev/lego0
user> export RCXTTY=usb
And then it works. :)
Bye,
Tom
