I should be ready to begin work on the next version of the LiveCD this weekend. At this point it will be based on the Kubuntu 8.04 LiveCD released last week. The question is, of course, what software should it contain? I haven't kept up with all the advances in the various little bits and pieces of software (eg. all the Gcode stuff) as well as I should so I'm hoping y'all will help me out. To start with I'll just add updated versions of what are in the old LiveCD and go from there: - All the java stuff needed for Reprap - The current Reprap.jar - Art of Illusion - minicom - poke I'm not so concerned now with keeping it down to CD size but still think thats most convenient. I may end up creating 2: one CD sized for most people and one DVD with all the extra bits and pieces people want but aren't 'core' but more developer tools like Eclipse. I'd like to keep as much functionality of the Kubuntu base as possible so it can be used to install on a new machine and have a machine that 'just works' for Reprap+most common tasks. This means that from the start I have conflicting goals but we'll see how it goes :-) Also, if you have any other LiveCD type distros that you think could do with a little extra Reprap functionality, list them here as well. Hopefully, once I've done it once, I'll have a list of commands to refer to and so making a second one wouldn't be too hard. As far as a basic timeline goes, I hope to have finished this in a couple of weeks and will definitely have it done by the end of May. BTW, I just noticed I'm now classed as Reprap Guru! Thanks to whoever/whatever did that. It makes me feel all warm and fuzzy inside. https://reprap.org/forum/read.php?12,11538,11538#msg-11538 Tue, 16 Jun 2026 20:40:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?12,11538,23624#msg-23624 https://reprap.org/forum/read.php?12,11538,23624#msg-23624 Martin Walch RepRap Host Wed, 20 May 2009 09:25:57 -0400 https://reprap.org/forum/read.php?12,11538,23460#msg-23460 https://reprap.org/forum/read.php?12,11538,23460#msg-23460

java.lang.UnsatisfiedLinkError: gnu.io.RXTXCommDriver.nativeGetVersion()Ljava/lang/String; thrown while loading gnu.io.RXTXCommDriver


and this error using Java 1.5:

java.lang.UnsatisfiedLinkError: nativeGetVersion thrown while loading gnu.io.RXTXCommDriver

On the 0.6 LiveDVD (Java 1.5 with the 0.8.3 host) it seems to work fine.

As this error could actually mean that java can't communicate with the device it may be a false lead but as rxtx is the only stuff I didn't install as per the instructions it would make sense if its having issues.

The easiest way around my particular issue is to use the 0.6 LiveDVD. This will get around my immediate issue and I'll look further into it in a few days time.]]> reece.arnott RepRap Host Wed, 02 Jul 2008 03:29:30 -0400 https://reprap.org/forum/read.php?12,11538,13775#msg-13775 https://reprap.org/forum/read.php?12,11538,13775#msg-13775
1) The Change.log on the DVD is not the up to date version. For those that are interested, the correct one is attached.

2) The reprap-0.8.3 shell script to run the old version of the host is not there. I'm not sure how that happened but you can run it using two commands at the terminal:

cd /etc/reprap-host-0.8.3
./reprap-host.sh

3) The Addins for Art Of Illusion have not been installed (this is also a problem for 0.6). From [dev.www.reprap.org] the way to do this is as follows:

Go to Tools -> Scripts and Plugins Manager menu. Select the Install tab. (Note that if you are behind a firewall you may first have to click on the Setup... button and enter details of your http proxy.) AoI will scan for scripts and plugins (this might look as if it has found nothing as sometimes no files appear in the window; ignore this absence and do the next thing anyway). Click Select all and then on Install selected files. AoI will get all the available plugins and enhancements and install them on your system.

4) The JAVA_LIBRARY_DIR path in the repap-host shell script for the 0.9 host is wrong; it is supposed to be "/usr/lib/jvm/java-6-sun/jre/lib/ext" (Thanks Wade). At this point it doesn't matter that this is wrong as this is a folder that will always be searched as long as the java version is set to 1.6.

It may be that the issues I'm having with /dev/ttyUSB0 not being accessible via the host is related to the 0.7 LiveDVD and not the host version/Java version/order in which things are turned on etc. so I'll test using the 0.6 LiveDVD (which will be the 0.8.3 host using Java 1.5) and see what happens.]]> reece.arnott RepRap Host Wed, 02 Jul 2008 01:14:36 -0400 https://reprap.org/forum/read.php?12,11538,13685#msg-13685 https://reprap.org/forum/read.php?12,11538,13685#msg-13685
Thanks for the new version of Live DVD, its really cool to have EMC2 on it too!

BTW, I am getting the same error with /dev/ttyUSB0

Before everything worked well and now with the new host it does not works. I also tried different turn-on-order but none worked. I keep trying though...

2) I think the RXTX error is related to the first error, fix one and the other will go away.

3) The Imagecon error is specifically an error associated with the 0.9 host and/or not running Java version 1.6. The 0.8.3 host will work on Java 1.5 or 1.6 but the 0.9 host will only work on Java 1.6 so maybe something is changing the default Java version. On the LiveDVD try rebooting and see if it goes away. If not then it probably is an issue with your video card and Java 1.6's support of it. It may be something that can be changed with the next reprap host version so post another thread about it.

4) Yeah, sorry about that. The old reprap host script wasn't tested properly. I had the same problem yesterday :-)]]> reece.arnott RepRap Host Mon, 30 Jun 2008 01:53:41 -0400 https://reprap.org/forum/read.php?12,11538,13675#msg-13675 https://reprap.org/forum/read.php?12,11538,13675#msg-13675 [ 306.068014] usb 4-1: FTDI USB Serial Device converter now attached to ttyUSB0

which is what works in my regular Ubuntu install and in the 0.6 CD, so I think that's all good.

I am getting a java error
java.lang.UnsatisfiedLinkError: gnu.io.RXTXCommDriver.nativeGetVersion()Ljava/lang/String; thrown while loading gnu.io.RXTXCommDriver
java.lang.Exception:
Could not connect at /dev/ttyUSB0.

so I'm guessing there's a problem with the RXTX library? I'm a total java noob, so I'm really guessing here. Trying to learn fast though.

Also, the reason I tried the live CD is that I kept getting this error on my Ubuntu install:
Exception in thread "RepRap" java.lang.NullPointerException
at javax.swing.ImageIcon.(ImageIcon.java:138)
at org.reprap.gui.botConsole.PrintTabPanel.initComponents(Unknown Source)

Which I'm also getting on the live cd, so maybe it's an issue with my particular video card (nVidia Quadro on a Toshiba laptop). I'll try 0.6 again and see if that works.

Finally, the older version script didn't work as it says in the readme; but by going to the /etc/reprap-host-0.8.3 dir and running reprap-host.sh, I got it to run without the ImageIcon exception, but it still hangs on the same RXTX error when I try to run the stepper exerciser.

Sorry, probably too much information, but I thought it might help. I'm going to try running the 0.6 CD again for reference, but it looks like reprap-host-0.8.3 is working better for me for now.

Yeah, the livecd 0.6 version still works for me - I get some errors on startup, but I can run a test build of the minimug without crashing, although without a working extruder I don't get very far into the build. :)]]> Wade RepRap Host Sun, 29 Jun 2008 12:59:43 -0400 https://reprap.org/forum/read.php?12,11538,13665#msg-13665 https://reprap.org/forum/read.php?12,11538,13665#msg-13665

This version is just the 0.6 version plus:
- Java 1.6
- Reprap host 0.9
- EMC2 software suite

Note that it now contains both the latest versions of the host software as well as Java 1.5 and 1.6.

As far as I can tell everything works but it may be a bit rough around the edges as this is just an intermediate release really.

Unless there are any serious issues I'm not planning on making another one until the 1.0 host software comes out or the next Ubuntu release in October (whichever comes first).

I'm going to be spending more of my time over the next few months on putting the final touches on my own Darwin machine and then calibrating it and finally printing stuff with it.

Yeah, thanks actually proxy was in the way. Now, avoiding proxy it coonects and downloads the update.

I now hit another wall not being able to compile from source. I have not been using Linux for a long time but until now I only found tar archives which were simple to compile. Other option was to use the makefile... In this case I found something new and do not know how to compile it. I was trying to search on wiki but did not find it.

Is there a description how to do this on linux?

The error message is basically saying that this folder doesn't exist and yet it obviously does so the only other thing is if you have a network issue eg. a proxy server in the way.

Actually just reading your other posts it looks like you're trying to get everything in one gulp (i.e. the trunk on down). Try going down a couple of levels and just checking out one subfolder eg. reprap/miscellaneous/LiveCD-scripts (just a few k) and then if that works, work your way up the tree.

As for the above errors I had with 0.9 host it seems as if there are 2 specific issues:

1. From [bugs.launchpad.net] this is a bug in the Ubuntu hardy distro's packaged xorg/libsdl which can be fixed in this case by doing the following:
sudo sed -i 's/XINERAMA/FAKEEXTN/g' /usr/lib/jvm/java-1.5.0-sun/jre/lib/i386/xawt/libmawt.so

2. From another thread the exception in swing is because its Java 1.6 specific.

If you're running it from the LiveDVD its easiest if you copy the entire zipfile contents and just leave the old version as is and forget about trying to upgrade it.

At first glance it should be simple to do.

1. Unzip to a folder eg. on the desktop and edit the reprap-host file.

2. Change the REPRAP_DIR variable to the folder all the files are in. In this case it would be "~/Desktop/reprap-host-20080523"

3. Change the JAVA_LIBRARY_DIR to "/usr/lib/jvm/java-1.5.0-sun/jre/lib/ext"

However, I have had issues with this and get the following error when I run ./reprap-host from the console (LiveDVD version 0.6):

Jonathan, do you have any ideas? Its probably a stupid java environment setting on the LiveDVD but I just don't know enough to decipher the error message.

I haven't got any spare machines to play with at the moment so all I can use is the LiveDVD.

I did notice however that the zip file contains a subfolder with one file in it that I wouldn't have thought belonged: org/reprap/Main.class and which I assume is important to have in the correct place.]]> reece.arnott RepRap Host Thu, 05 Jun 2008 05:15:39 -0400
