Error about faster HOT 7 CLOSED

Hi @xujiahuan!

This seems a similar error as this other issue. Specifically, check these versions:

Ubuntu 18.04 and ROS Melodic
protoc --version should give libprotoc 3.0.0
gazebo --version should give version 9.0.0

Ubuntu 16.04 and ROS Kinetic
protoc --version should give libprotoc 2.6.1
gazebo --version should give version 7.0.0

Hi, developer!
Thank you for your answer!
However,I I had other problems.

Does this need OpenCV and PCL? If so, what are the versions? Thans a lot.

from faster.

Hi @xujiahuan!

Yes, you need PCL (which is usually installed when installing ros-desktop-full I think). Could you try to install it by running
sudo apt-get install ros-melodic-perception-pcl? (change melodic with the ROS version you are using)

Let me know if this solves the problem

Hi @jtorde !
Thank you for you answer.
I still can't solve these problems on my pc.
However, My classmate successfully Compiled it on his computer. His Ubuntu is 16.04/ROS Kinetic, while mine is 18.04/ROS Melodic. So, Maybe it can't be Compiled on Ubuntu 18.04/ROS Melodic? I just guess. Could you provide me with accurate environment configuration? Thank you very much.

Hi @xujiahuan,

FASTER has been tested and compiled successfully both in Ubuntu 16.04/ROS Kinetic and Ubuntu 18.04/ROS Melodic. So it should work with the Ubuntu/ROS version you have.

Are you getting the same error as before? If so, could you try to install as well this package (if not already installed): sudo apt-get install ros-melodic-vision-opencv

Let me know if this helps!

from faster.

Or more generally, make sure all the packages that come with the Desktop-Full install of ROS are installed:

sudo apt install ros-melodic-desktop-full

Closing this for now, feel free to reopen it you still have this issue
