I have diamondback installed but didn't understand that "unstable" is referred to the ROS version. Now that I know this is trivial.

ros-diamondback-gps-umd

did the trick. Thanks a lot, Dryanovski

Which version of ROS did you install - unstable or diamondback? If you installed unstable, everything should be in /opt/ros/unstable/stacks. If you installed diamondback, you should probably use ros-diamondback-gps-umd instead. - Ivan Dryanovski (13 hours ago)

Problem 1 is not a problem, it is normal. The path variable applies to all applications not just ROS so it points to the typical Linux directories.

Problem 2 doesn't seem like a problem either. Binary files are executable machine code. You aren't expected to look at them with a text editor. You would need a debugger or disassembler to make any sense of them.

3 - I assume the "Problems" heading you mention is actually "Console" window? Make sure the missing path actually exists then Go to Project/Properties and add the missing include path. It should have been included when you imported the project after doing the make project-eclipse, if your original version of the talker/listener was successfully compiling/running from the command line development steps in the tutorial.

Problem 4 is simple when you know how (but not when you don't). If the file has not been edited since the last successful compile, the Project/Build Project option is greyed out. Go to the source file, enter a single space somewhere and try again.

Hi everyone

I'm trying to get a newly installed stack to work, it's my first time so be gentle :). The package I would like to install is gpsd_client. So I used following command, with the stack name found here

sudo apt-get install ros-unstable-gps-umd

and this seems to run through properly. If I run it again it says "ros-unstable-gps-umd is already the newest version", so that sound good. If I then run

rosrun gpsd_client gpsd_client _host:=localhost _port:=2947

I get the error "[rospack] couldn't find package [gpsd_client]". What did I miss? And where did the installed files go? Intuitively I would expect to /opt/ros/releasename/stacks ... but there I dont find it.

Hi everyone,

I'm trying to set up Eclipse to use as IDE for my ROS packages. I decided to go with Eclipse above any other IDE because it's listed first in the ROSwiki. http://www.ros.org/wiki/IDEs I tried to follow steps 1-4 so far. I'm afraid a few things went wrong tough:

PROBLEM 1: ROSwiki Instructions step 4: Properties --> C/C++ Make Project --> Environment, and check whether the following environment variables are assigned to the correct values:

ROS_ROOT

ROS_PACKAGE_PATH

PYTHONPATH

PATH

My issue: These variables were added, also in my case, but I dont understand their assign value: for e.g. path the value the value is set to /opt/ros/diamondback/ros/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games which is also what i get if using "echo $PATH" ... is this correct? is this valid path? why to "mulitple" locations

PROBLEM 2: If I have a look at the binaries in my packate (I use the "beginners_tutorial" package as described on the ROSwiki) there is the "listener" and "talker" but they contain garbage like ELF

�URHCF�* ���&�DMh()�

now if i expand the "talker" i also do find the "correct" code in a cpp file. But it seems something went wrong anyway if I have somethink like to above, no?

PROBLEM 3: under "Problems" I get one warning Description Resource Path Location Type Invalid project path: Include path not found (/opt/ros/diamondback/ros/core/roslib/msg_gen/cpp/include). beginner_tutorials-RelWithDebInfo@beginner_tutorials pathentry Path Entry Problem

PROBLEM 4: I just cannot build the project, the build button is greyed out.

Really glad for any help with my problems. Many thanks in advance.
