Hi: I want to modify the RRT algorithm in OMPL so I searched online and want to complies vrepExtOMPL. I followed the steps in this And I have finished building the OMPL Plugin for V_REP step But when I compile the plugin code to build the plugin with cmake . cmake --build . I get this error

It seems something wrong with my C++ complies But I don't know how do fix that. My gcc verison is gcc version 7.3.0 (Ubuntu 7.3.0-27ubuntu1~18.04)
