Hi,
I’m not sure if the sync is the actual cause, but after I apt-get upgrade, build of some packages fails in my environment.
The problem occurs when a package with parameter files for dynamic_reconfigure (e.g. compressed_image_transport) is already installed via apt-get and also is located on catkin workspace and there is difference between parameter files of the packages.
It looks like g++ looks at header files generated from dynamic reconfigure params on /opt/ros/melodic instead of the current catkin workspace.
I further looked into build logs and found that devel directory is passed to compiler using -isystem instead of -I.
To reproduce the issue:
sudo apt-get install ros-melodic-compressed-image-transport
source /opt/ros/melodic/setup.bash
mkdir -p ~/catkin_ws/src && cd ~/catkin_ws/src
git clone https://github.com/ros-perception/image_transport_plugins.git -b indigo-devel
cd ~/catkin_ws
catkin config --init
catkin build
Log on environment BEFORE apt-get upgrade:

I’m not sure the issue comes from catkin package, so I posted here.
Hope it helps!
