ROS groovy problems

[Soumajyoti Sarkar]

I installed ROS groovy and  rapyuta-mapping but the problem with ROS is that it fixes ROS_PATH to /share/ros. I have to do an export to the correct directory to resolve the path everytime. I looked up the internet and there were people who suggested deleting the devel and build directories and then redo a catkin_make, but it still doesn't work in my case. If I do an export everytime , the framework works fine. I know it is more of a ROS problem than rapyuta's , but I posted it here just in case anyone here might have already faced this issue before.What is the solution to this?

Sorry I haven't used catkin. However, if you need to export it everytime just add it to your .bashrc.

Hi Soumajyoti,

If you mean that ROS_PACKAGE_PATH is not pointing to the place where you have your packages, then it should be fixed by adding 

source ~/workspace/devel/setup.bash

to your ~/.bashrc

If there is no mistake and you are actually talking about ROS_PATH, then I'm not sure. I don't have this variable at all.

Hi all,

I use ROS groovy and catkin for my workspace, 

I had added source ~/{my_workspace}/devel/setup.bash to ~/.bashrc

however it is not work and error message is 

Received the following error message when calling createNode from class Environment: Can not find ROS package "{package name}"

So I try to copy the executable bin in  devel/lib/package/ to devel/lib/package/bin

and add the address to [machine/packages], now this time no error message.

But this seems not a good solution, so what can I do to deal with catkin package?
