Hi, I am trying to install ROS indigo on Ubilinux - Edison following this tutorial. I symlinked /opt and /var/cache/apt to 2 folders in a microSD card in order to make room for the desktop package. It all went through up to: 2.3 Building the catkin Workspace. I have this error message:

==> Processing catkin package: 'catkin'
==> cmake /root/ros_catkin_ws/src/catkin -DCATKIN_DEVEL_PREFIX=/root/ros_catkin_ws/devel_isolated/catkin -DCMAKE_INSTALL_PREFIX=/opt/ros/indigo -DCMAKE_BUILD_TYPE=Release -G Unix Makefiles in '/root/ros_catkin_ws/build_isolated/catkin'

-- Could NOT find PY_em (missing:  PY_EM) 
CMake Error at cmake/empy.cmake:29 (message):

<== Failed to process package 'catkin': 
  Command 'cmake /root/ros_catkin_ws/src/catkin -DCATKIN_DEVEL_PREFIX=/root/ros_catkin_ws/devel_isolated/catkin -DCMAKE_INSTALL_PREFIX=/opt/ros/indigo -DCMAKE_BUILD_TYPE=Release -G Unix Makefiles' returned non-zero exit status 1

Reproduce this error by running:
==> cd /root/ros_catkin_ws/build_isolated/catkin && cmake /root/ros_catkin_ws/src/catkin -DCATKIN_DEVEL_PREFIX=/root/ros_catkin_ws/devel_isolated/catkin -DCMAKE_INSTALL_PREFIX=/opt/ros/indigo -DCMAKE_BUILD_TYPE=Release -G Unix Makefiles

Command failed, exiting.

Now my folder structure is: ~/ros_catkin_ws rather than /root/ros_catkin_ws. I don't know if this could be the main problem or if the missing PY_emvisgenerating the error.

Thank you in advance, Marcello

Ok it was just unresolved dependencies at paragraph 2.2 I hope this could serve to someone else. The message in the blue box is kinda misleading.

Note: Rosdep may report that python-rosdep, python-catkin-pkg, python-rospkg, and python-rosdistro failed to install; however, you can ignore this error because they have already been installed with pip.

I did not bother the debug messages giving error on .py files and went on.

Afterwards I re-ran the command at 2.2, checked the debug info more accurately and found the bug. Problem solved
