Hi, I'm not familiar at ROS errors,, firstly , i installed Roboearth Stack using these four steps :


the result of that : I have the roboearth stack in Home/ros

i made a connection between this and ROS by opening bashrc file and typed "export ROS_PACKAGE_PATH=/opt/ros/fuerte/share:/opt/ros/fuerte/stacks:/home/ros"

and saved

i begin to run re_comm package in roboearth stack but itthrow an error

salma@salma-G31M-S2L:~$ rosrun re_comm run
[rospack] Error: stack/package re_comm not found

i don't know why ??? re_comm not in /opt/ros/fuerte/stacks but in /home/ros/roboearth

why not found ??

and this is the result of rosmake roboearth now

salma@salma-G31M-S2L:~$ rosmake roboearth
[ rosmake ] rosmake starting...                                                 
[ rosmake ] Packages requested are: ['roboearth']

[ rosmake ] Expanded args ['roboearth'] to:

Are you sure /home/ros is the correct directory for roboearth? In FHS (Filesystem Hierarchy Standard), the home directory ~/. is the same as /home/username/. /home/. is a different place. Since your username is salma, I'd guess that you should use /home/salma/ros instead of /home/ros
