can't find packages

I'm new to ROS. I got a project from previous developer and now i'm trying to compile it. the project uses several dependent packages (such as eigen, tf etc.) but it can't find any of them.

I installed ROS according to instructions and I can find these packages in /opt/ros/diamondback/stacks, but when I try to call rosmake or rosdep to any of them it fails to find them.

as I understood it searches in /home/username/.ros/rosmake/ when i call rosmake, which of course isn't correct. Where should I change it?

this is how it reacts to rosmake:

sergey@ubuntu:/opt/ros/diamondback/stacks/geometry$rosmake tf
[ rosmake ] Packages requested are: ['tf']                           
[ rosmake ] Logging to directory/home/sergey/.ros/rosmake/rosmake_output-0110825-143550
[ rosmake ] Expanded args ['tf'] to: >[]                                                             
[ rosmake ] WARNING: The following args could not be parsed as stacks or packages: >['tf']           
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

Thank you

rosmake doesn't search in $HOME/.ros/rosmake. It's just the directory it puts some logs in.

I assume that you are using Ubuntu and installed ros with debian packages. If the system cannot find tf, I suspect that you installed ros-diamondback-base and not the recommended package ros-diamondback-desktop-full. To fix it, just execute the following in a terminal:

sudo apt-get install ros-diamondback-desktop-full

If that doesn't help, something is probably wrong with your ROS_PACKAGE_PATH. In that case, can you please post the output of

echo $ROS_PACKAGE_PATH

2 Lorenz I installed the full package and it doesn't want to update any more.

and this is the output you asked for:

sergey@ubuntu$ echo $ROS_PACKAGE_PATH opt/ros/diamondback/stacks

it looks to be correct.

What do you mean with 'it doesn't want to update anymore'? Did you do a `sudo apt-get update` and then the `sudo-apt-get install ros-diamondback-desktop-full`? What exactly was the error? The output of the echo command is missing a preceding /. But I guess that's just a copy-paste error.

Yes, tried the apt-get, it said i have the newest version. The problem was in missing /. Thanks )

You do not need to make anything if you installed via packages. The code in /opt already comes compiled.

Nevertheless it should find the packages. Did you source /opt/ros/diamondback/setup.bash (or just setup.sh if not using bash)? If yes, rospack find tf should output /opt/ros/diamondback/stacks/geometry/tf and everything is fine.

Hi,

I am also new to ROS, today I was testing some code with tf and dometry, the compiler used to return no such file or directory once I issue rosmake after adding the include for the header files and fixing the manifest.xml file. I resolved the problem by issuing a cmake . command in order to compile and link the files then rosmake. And everything went good then. Not sure if this would help in your case, hope so.

Good luck,

Rosmake actually executes make which creates a build directory in which it calls cmake. Calling cmake by hand should never be necessary and might actually screw things up. If you execute `cmake .` in a package root, it might overwrite ros' original Makefile which can lead to further problems...
