After Third re-install I got it to work. Don't know why though.

Thanks, Cody. I've updated my post. The forum's displaying the code lines all screwy and I can't change it. No idea why. They should look like this. #include <std_msgs strings.h> and #include </home/ryan/sketchbook/libraries/std_msgs/Strings.h>

When I compile the "Hello World" example in the Arduino IDE I get this message:

HelloWorld.cpp.o: In function global constructors keyed to nh': HelloWorld.cpp:31: undefined reference toros::normalizeSecNSec(unsigned long&, unsigned long&)' collect2: ld returned 1 exit status

I arrived at this point after painstakingly editing the code of every file in the relevant sequence so that every #include "(some_file_name)" reference contained the full directory address to fix "No such file or directory" error messages. So:

"ros/msg.h"

became

"/home/ryan/sketchbook/libraries/ros/msg.h"

And it seemed to be working (at least it stopped throwing up those error messages) but I can't figure this error out. I'm stuck. Any help would be greatly appreciated.

Thanks for the input, Cody. I've mirrored the formatting as it is in the files and it seems to have worked. Those errors looked a bit like this"

HelloWorld.cpp:7:29: fatal error: std_msgs/String.h: No such file or directory compilation terminated.

This one is a bit different as it refers to a line of code directly in the "Hello World".pde file. Following the same tactic as before I modified it from:

include <std_msgs strings.h="">

to

include </home>

When I do this the compiler posts the error message I listed right at the top of my post. I don't know if this means I fixed that problem and am on to the next, or if the modification caused this error. I'm wondering if the IDE can't locate everything in my sketchbook for some reason. I assume I messed up something on the setup but I had no errors there that I could tell and the IDE sees the ros example files just fine, they're listed in its menus. Either way I'm still stuck.

UPDATE: I repeated the tutorial and discovered that rosmake fails after the command: rosmake rosserial_arduino. The rosmake summary reads like this:
[ rosmake ] Output from build of package rosserial_arduino written to: [ rosmake ] /home/ryan/.ros/rosmake/rosmake_output-20120514-181947/rosserial_arduino/build_output.log [rosmake-0] Finished <<< rosserial_arduino [FAIL] [ 6.52 seconds ]

What would cause rosmake to fail?

I'm working on the rosserial_arduino/Tutorials/Hello World tutorial and when I compile the example code I get this error message:

In file included from /home/ryan/sketchbook/libraries/ros_lib/ros.h:38:0, from HelloWorld.cpp:6: /home/ryan/sketchbook/libraries/ros_lib/ros/node_handle.h:39:38: fatal error: rosserial_msgs/TopicInfo.h: No such file or directory compilation terminated.

I've tried copying and pasting files and folders with no luck. I'm thinking maybe Arduino can't find my ros_workspace folder?

Any ideas?

I just installed ROS and was starting the tutorials. I tried opening a new terminal window and it opens with the header "/bin/bash". After a long delay I get this message:

"bash: /usr/bin/dirname: Argument list too long"

This repeats for a while then the window crashes. My "bin" folder has 1,880 items. Seems like a lot. I'm new to ubuntu and their forums don't seem to have anything on this. Any suggestions would be great.

I just started the Tutorials and the 'rosmake beginner_tutorials' command gives me this output:

[ rosmake ] Packages requested are: ['beginner_tutorials']
[ rosmake ] Logging to directory/home/ryan/.ros/rosmake/rosmake_output-20120314-092824 [ rosmake ] Expanded args ['beginner_tutorials'] to: []
[ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['beginner_tutorials'] [ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

According to the tutorial I should have something like this:

[ rosmake ] No package specified. Building ['beginner_tutorials'] [ rosmake ] Logging to directory [ rosmake ] /home/dbking/.ros/rosmake_output-2009-09-22-03-17-14 [ rosmake ] [ 0 of 18 Completed ] [rosmake-0] >>> genmsg_cpp >>> [ make ] [rosmake-0] <<< genmsg_cpp <<< [PASS] [ 0.39 seconds ] [ rosmake ] [ 1 of 18 Completed ] [rosmake-0] >>> roslib >>> [ make ] ... ... ... [ rosmake ] [ 17 of 18 Completed ] [rosmake-0] >>> beginner_tutorials >>> [ make ] [rosmake-0] <<< beginner_tutorials <<< [PASS] [ 0.79 seconds ]

I thought I had followed everything up to this point successfully, but I can't seem to find the problem. Any thoughts?
