Problem in building the package.

[bharath0404]

Just like issue #11, I get a lot of errors. A little introduction to my system - ROS Melodic - Ubuntu 18.04. I have installed and built FCL Library many times in many workspaces. Didn't resolve the problem. Tried installing 0.5.0 as stated in a different issue. It didn't work. Please address this problem.

The errors are depicted as follows:

This could be due to fcl version conflict. Try removing all previously installed fcl related files (probably in usr/local/lib, include, lib/cmake) from the system and install fcl version 0.5.

[ayushgaud]

You may also use the fcl-0.6 branch. It works with ROS melodic.

I tried that but nothing.
