rplidar_ros fails to build MacOS X

edit

Dear ROS community,

while trying to build the rplidar_ros package in the catkin_ws I get the following error:

Scanning dependencies of target rplidarNodeClient

<== Failed to process package 'rplidar_ros':
  Command '['/Users/alessandrodortenzio/catkin_ws/install_isolated/env.sh', 'make', '-j4', '-l4']' returned non-zero exit status 2

Reproduce this error by running:
==> cd /Users/alessandrodortenzio/catkin_ws/build_isolated/rplidar_ros && /Users/alessandrodortenzio/catkin_ws/install_isolated/env.sh make -j4 -l4

By looking online I have found out that the methods causing the errors are not available in the OS X environment. Although, on the rplidar github page they have listed the OS X as a supported operative system.

My question is, what am I doing wrong? Is there any workaround for this error?

Thanks in advance for your time.

Sincerely,

Alessandro
