The output of my

echo $ROS_PACKAE_PATH is

/opt/ros/hydro/share:/opt/ros/hydro/stacks

But when i try to do this:

cd opt/ros/hydro/stacks

it gives the following error:

bash: cd: opt/ros/hydro/stacks: No such file or directory

Although i can access the 'share' folder using cd opt/ros/hydro/share

Why cant i access the 'stacks' folder? i have to clone a repository from git and i need to cd into this 'stacks' folder. I'm using Ubuntu 12.04 & ROS Hydro.

Why cant i access the 'stacks' folder?

Probably because it doesn't exist on your machine. It's a remnant from older ROS versions, so not always needed.

i have to clone a repository from git and i need to cd into this 'stacks' folder.

This sounds like outdated instructions: normal ROS packages (for anything recent) don't work that way anymore.

Can you tell us which package(s) you are trying to work with? Perhaps something needs to be changed.

Those all seem to be catkin pkgs. Why do you think it is necessary to "cd into this 'stacks' folder"? Just setup a normal catkin workspace, clone the repository into the src dir and build.

I did exactly that once i couldnt find 'stacks'. i thought it necessary because the tutorials on internet were all referring to this 'stacks' folder.

"all tutorials on the internet"? Can't help you there, but for normal catkin pkgs you should not do anthing in the stacks directory.

do not clone the repository in stacks folder...cd to your ros workspace and clone it there. Example:

cd catkin_ws/src
git clone <address>

Thats what i did. Now the error i'm getting is Invoking cmake failed when i try to catkin_make in the root of my directory.
