Hi, when I run "roslaunch gazebo_ros empty_world.launch", the error "Can't open /usr/share/gazebo//" occurs at both the 'gzclient' and 'gzserver' . It's a weird path "/usr/share/gazebo//", right? btw, I can't find the folder 'gazebo' neither.

Pls help, thx!

just attach the terminal prints:

You need to have /usr/share/gazebo/ which contains the file and a folder named cmake in which there is the gazebo-config.cmake file. Check if you have those files. According to me, there is a slash too many in the path specified at the line 22 of the gzserver server.

it's weird that i don't have the folder "/usr/share/gazebo", I thought it becuz I hadn't installed the gazebo, but when I run sudo "apt-get install ros-jade-gazebo-*" the terminal shows me that the gazebo was already installed with the latest version. I am so much confused now!

It is effectively strange. If gazebo is properly installed, I don't understand why you have not this folder.

I just installed jade and I have exactly the same problem; it seems like the installation of gazebo is partial.

You don't have to ask a question as an answer. You can let a comment or ask a new question but not use an answer to ask a question. Else, have you installed the full gazebo ?
