I have been able to build this package in the past and am unclear on why it is now not building.

I even created a new workspace and reinstall foxy.

Any help would be appreciated. This was gotten from: git clone -b foxy-devel https://github.com/ROBOTIS-GIT/DynamixelSDK.git

After I type in colcon build

Starting >>> dynamixel_sdk
Starting >>> dynamixel_sdk_custom_interfaces
