Hi, I've successfully installed ROS Groovy in Gentoo using the source, and I've completed the beginner tutorials successfully. When it came to the roswtf tutorial, I got all these errors about PYTHONPATH inconsistencies. The output is here: (http://)bpaste.net/show/93407/

It seems to suggest that the python libraries for many packages were not built.

Am I correct in this understanding?

What could I have done while building from source to ensure that the python libraries were built?

Also, about the ROS_PACKAGE_PATH errors - do I need to worry about them?

Looking forward to your help. Thanks.

Hi, I have been following the instructions from www.ros.org/wiki/groovy/Installation/Source to build ROS Groovy on Gentoo x86_64 and it is nearly there! Just one thing fails for me right at the end. I would be very grateful for help in solving this.

The catkin ws is built and the rosbuild ws fails right at the end with this message:

I have searched for the move_base_msgs package and it does not exist on my computer. How do I install this package so I can move on to bigger and better things :)

Thanks again for your help.

Yes, I had to rebuild vtk from source and it worked. Thanks.

Hi, I'm trying to install groovy from source on a Gentoo laptop using instructions from here:

www.ros.org/wiki/groovy/Installation/Source

It fails while building the point cloud library. Please help on how to proceed.

Thanks.

The command I'm using to build is:

./src/catkin/bin/catkin_make_isolated --install-space /opt/ros/groovy --cmake-args -DSETUPTOOLS_DEB_LAYOUT=OF

This is the first error it threw up while building the pcl package:

But then it goes on and then breaks down completely here:

Reproduce this error by running:
==> /home/ro/ros_catkin_ws/devel_isolated/nodelet_topic_tools/env.sh make -j4 -l4

Command failed, exiting.

does anybody know anything about what may be wrong, either with the wiki or with what I've done??

Hi,

I just installed ros groovy from source on gentoo amd64 and am working through the beginner's tutorials. I'm on the "Understanding ROS Nodes" tutorial and installed the ros_tutorials metapackage from git using catkin_make in a catkin ws. I've sourced the correct env variables and rospack list shows that ros_tutorials/turtlesim package is installed. However, the above mentioned command fails, and a listing of all the turtlesim related directories shows no file named as turtlesim_node. Here is my output:

$ rosrun turtlesim turtlesim_node
[rosrun] Couldn't find executable named turtlesim_node below /home/user/ros-groovy-metapackages/src/ros_tutorials/turtlesim
$ roscd turtlesim

Hey did it work for you? I'm meaning to try installing groovy on a gentoo machine, but I'm concerned I might get stuck on something I can't solve..
