Compilation with tf and tf2

[FabianSchurig]

Installing and using the robot_navigation by binaries with apt install ros-melodic-robot-navigation works fine. Now, I want to add some changes and tried compiling it with catkin from source. catkin build throws the following error.

I am using Ubuntu 18.04 LTS running ROS melodic and checked out the tf2 branch.

Errors     << nav_2d_utils:make /home/xxx/ws/logs/nav_2d_utils/build.make.002.log

@DLu do you have any hints on compilation or do I miss something?

Thank you in advance!

It is the -Werror flag in the CMakeLists.txt because I might use a different compiler.

set_directory_properties(PROPERTIES COMPILE_OPTIONS "-std=c++11;-Wall;-Werror")
