I have commited a new jrStepGUI version (r82). A compiled version is
available at http://code.google.com/p/rstep/downloads/detail?name=jrStepGUI_110113.jar

This version has minor bug corrections. I have adjusted the appearance
of the input fields in the Configuration window. It should now work
fine on Linux and OS X.

It is still 'waiting for rStep' with my arduino328 clone board with
rStep code
Is there any checking method whether my mac RXTX installation fits
whit rStep or not?

You should try to run jrStepGUI from a terminal. You'll be able to see
the exceptions eventually thrown.
If RXTX is missing you'll get a java.lang.UnsatisfiedLinkError.

Is RXTX now included in the jrStepGUI distribution? I've also tried to compile it myself, but I can't get eclipse to work on my new box (windows 7 x64). It throws a JNI error every time. I'll have more time to play with it in 2 weeks after I take my qualifying exam.

I can't run jrStep in terminal. It tells me '-bash: ./
jrStepGUI_110113.jar: cannot execute binary file'
Is is impossible to run java binary in terminal? Am I did wrong?

what version(size?) of your RXTX in OSX /Library/Java/Extentions/
librxtxSerial.jnilib RXTXcomm.jar
When I installed reprep mac installer Arduino crashed when uploading.
So I googled and found it was related with RXTX in /Library/Java/
Extentions/
And I found same name but different sized files in Arduino package. I
replaced the two files with the ones in Arduino package. And Arduino
Works fine and reprep don't.
Again,
In case A when I use librxtxSerial.jnilib 274KB and RXTXcomm.jar
61KB jrStepGUI only waiting, Arduino fine, reprap can't start with
errors
In case B when I use librxtxSerial.jnilib 172KB and RXTXcomm.jar
61KB jrStepGUI tells RXTX version mismatch, Arduino crashs, reprep
works
I suspect reprep installer, it might did some more bad thing to my mac
beside the two file replacement.
Or my file replacement was not good action for jrStepGUI?
Anyway could you tell me your RXTX file size in mac /Library/Java/
Extentions?

How do you run this on Mac OSX 10.6.6?
I get this when running in terminal mode. I copied the two files from
Arduino to the Java extensions directory. I chmod the files to include
execute.

MyMAC:GUI arduino$ ./jrStepGUI_110113.jar
-bash: ./jrStepGUI_110113.jar: cannot execute binary file
MyMac:GUI arduino$

When I run it from the Finder, GUI came up and everything is grayed
out. The status message shows "waiting for rstep".

My Arduino application works and the terminal shows "start". I am
using a Arduino Pro board with Atmega328.

Please advise,
David

I've not played with the latest version of jrStepGUI but did you select the correct serial port and have the proper RXTX drivers installed? That seems to be a problem for multiple people. Has it been included in te jrStepGui distribution?

Reaz,

I downloaded the jrStepGUI from the google group. I copied the RXTX
drivers to the "Java extensions" directory. I ran the GUI with
everything grayed out. There is no way to select the comm port. I
tried to run with terminal and I get cannot run message.

Arduino version 0022 works on ATmega328 board. I uploaded your version
of rStep firmware and I can invoke the terminal to communicate with
the board.

I just cannot get the GUI to work.

Yup, your right - there must be a bug with the latest version. Before I used to be able to configure the serial port and the current version doesn't give me that option anymore. I know I've gotten it to work before, but I downloaded the older version and had the same problem. According to the source, it should pop up a dialog right away to prompt for the serial port. I don't have time this week to do anything so hopefully someone else can debug it. I still havn't been able to get the 64bit version of eclipse to run on this new computer to start playing around with the code.

    public Application() {
                rStep = new RStep();

                // connect a PrintStream to monitor rStep I/Os
                rStep.setSerialMonitor(new PrintStream(getSerialJPanelOutputStream(), true));
                rStep.setTimestamping(true);

                // listen to some rStep outputs
                EventBus.subscribe("RStep START", this);
                EventBus.subscribe(Pattern.compile("RStep Reply:.*"), this);
                EventBus.subscribe(Pattern.compile("RStep Debug:.*"), this);
                EventBus.subscribe(Pattern.compile("RStep Syntax error:.*"), this);

                EventBus.subscribe(Pattern.compile("RStep Sen[dt]"), this);
                EventBus.subscribe(Pattern.compile("RStep CommunicationException"), this);

                rStepPlayer = new RStepPlayer();

                // listen to all RStepPlayer outputs
                EventBus.subscribe(Pattern.compile("PlayThread.*"), this);

                mainJPanel = new MainJPanel(this);
                this.getContentPane().add(mainJPanel);

                this.addWindowListener(new ApplicationWindowEventHandler());
                this.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

                this.setTitle("jrStepGUI");
                this.setSize(700, 525);

                MySwingUtilities.displayCentered(this);

                setUIState(UIStates.STARTUP);
                this.setVisible(true);

If the serial port selection dialog doesn't appear, it means that the
RXTX library isn't properly installed (I have reproduced the "bug" on
my Linux box to be sure).
The RXTX library relies on a Java library file and one (or two) native
library file which depends on the OS you use. I use to link the Java
part in jrStepGUI but I can't do the same for the native part as it
varies.

I'll try to add a popup to notify the problem to the user but I can't
fix it, as the way to do that depends on the OS.

It seems the better way to install RXTX is the web install:
http://show.docjava.com:8086/book/cgij/code/jnlp/gnu.io.SafeCommDriver.jnlp
But a manual install may be necessary if the web install doesn't work:
http://rxtx.qbang.org/pub/rxtx/rxtx-2.1-7-bins-r2.zip

The web install failed with a popup message stating "Unable to launch

When I manually install and fix the permission, same problem with no

Anybody else get in to work on Max OSX 10.6.6? What is the correct

By the way, the date on the two files are much older and different

How do the arduino people manage to bundle them together (rxtx w/ code)?

And would it simplify things at all if the code was ported to processing and we reused all your libraries? I know nothing about java GUI programming -- and it's been a decade since i did enterprise java coding.

I'm going to upload a folder with the two RXTX files I've been

you. if they don't, watch your console and relay the errors back here

to rstep

The Arduino SDK archives contains the application and the libraries
(and many other files). We can do the same but then we need to build a
bundle for each target OS (a bit laborious).

Java look for the native libraries in a directory specified by a
property called java.library.path. If the libraries aren't in the
proper directory the Java virtual machine throws a
java.lang.UnsatisfiedLinkError exception. We can extend the
java.library.path property with a shell variable. The variable name
depends on the OS. On OS X, the variable is called DYLD_LIBRARY_PATH
(afaik) but I don't know how to set it once for all as I'm not a Mac
user (see http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man1/dyld.1.html).
However, if you want to do this with a shell script, you may write
something like that:

#!/bin/sh
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:.:lib
java jrStepGUI.jar

Before running that in the jrStepGUI directory, it will be necessary
to copy the native library files in the the same directory or in a lib
subdirectory.

I think it would work, I'll test it under Linux tomorow.
