now what is the output of the 'groups' command?
It should list you as a member of group dialout
wayoda@rebooter:~$ groups
wayoda adm dialout cdrom plugdev lpadmin admin sambashare

if not add yourself to this group
sudo adduser blaise dialout

and start the IDE to check if you can now see the board

 sorry I didn't check what I typed, missed a slash

ls -l /dev/ttyUSB*

OpenJdk works fine for most arduino users. If there are problems with this version they are mostly related to graphics or window-menus not working.

The alternative is to use the sun-java6-jre package (install, then run the update-alternatives line again to select it).

Please have a look at the IDE's startup messages again. Are there any error reports.

The Serial Ports Menu is only populated when the Arduino is plugged in. It takes a few seconds for the /dev/ttyUSB* entry to be added to the menu.

Please show us the output of ls -l /devttyUSB*

the output says the arduino is detected by the operating system so it should also be detected by the IDE.

Which java version is installed on your machine?
sudo update-alternatives --config java

Are there any error messages printed to the console window if you start up the IDE from the commandline.

try this:
Start up your computer
Open a console window
Run command "sudo dmesg -c" which prints and clears the kernel log messages since startup
Now plug the arduino board into an USB port
Run command "dmesg" in the console (no need to do this as root this time )
Post the output of the command it should look something like this

as you might know an arduino-sketch (pde-file) has to be preprocessed by the IDE to turn it into plain C-code that is handed over to the compiler.
This involves  searching for all library-include statements in the main pde-file, and adding a compiler-directive to have them included in the resulting upload-code.

But the arduino-preprocessor does not do this for your extra *.h or .*cpp in your sketch. So what you are trying is not possible (with the current arduino-IDE version).


38  Forum 2005-2010 (read only) / Troubleshooting / Re: EthernetDHCP on 0019? on: September 08, 2010, 04:08:16 am
A possible reason for this is mentioned in the Release Notes for 0019:
ARDUINO 0019 - 2010.09.03

[core / libraries]

* Revised Ethernet library (by Christian Maglie).  This depends on the
  new SPI library, so existing sketches will need: #include <SPI.h>
  added to the top of their code.

libraries go into your sketchbook directory.

On my machine the sketchbook folder is in /home/wayoda/sketchbook

Create a new directory on ypour machine
/home/<your user name>/sketchbook/libraries
and install the libs into this directory

You should at least read this page here

I've just encountered a problem similar to this (on my fresh install of Debian 5/Lenny) and fixed it by installing the following:


Some of those probably don't need to be installed but I just installed the lot and it seems to work.
You don't need avrprog, but all the others must be installed to run the IDE on Linux

did a checkout on ubuntu 10.04 just now. Took a while (google-code is not really fast) but worked.
svn checkout arduino-read-only

ever considered "the slackware page" might not be mean something to anybody in this world ?

What about setting a link to "the slackware page"??

Hi, quick solution:
remove the preferences.txt file.

Start arduino-0018
remember the location of the 'preferences.txt' file given on that dialog
Close the IDE
remove the 'preferences.txt' file
Start arduino-0016 (will prompt you for the sketchbook loaction again)

A much better solution would be trying to find out why you can't use 0018 for your project.
