Problem for install gazebo_ros_package

edit

The problem is in the scripts located in /opt/ros/indigo/lib/gazebo_ros. There are several scripts (i.e. gzclient, gzserver, etc.) which are executed when you perform a rosrun command. When trying to run gazebo, ROS needs to source the gazebo setup.sh script to make sure that the proper gazebo paths are defined. This is the line in the ROS scripts which has a problem:

setup_path=$(pkg-config --variable=prefix gazebo)/share/gazebo/

The problem is that pkg-config should find the path to gazebo, but it doesn't seem to work. Since it doesn't find gazebo, the script just continues execution using "/share/gazebo/" as the path. I tried looking around, but couldn't find an easy fix. Also, it looks like there is an extra slash at the end.

If you want a quick fix to just get things running, manually edit the gzserver and gzclient files to point to the directory which contains the setup.sh file. The default install location is /usr/share, so I changed my scripts to this:

setup_path=/usr/share/gazebo

If anyone knows what the correct fix is, feel free to chime in.
