Issues linking ROS2 rmw_fastrtps_cpp package after installing FastRTPS from source/binary

Another issue:

• Installing FastRTPS from source can cause your ROS installation to fail to link correctly. This will cause even ros2 run demo_nodes_cpp talker to fail with a linker error. I have found that I can resolve this issue on my machine if I remove the system install of FastRTPS with the exclusion of the fastrtpsgen executable and .jar files and re-installing ros-$ROS2_DISTRO-desktop

Example error:
ros2 run demo_nodes_cpp talker

failed to initialized rcl init options: failed to load shared library of rmw implementation. Exception: Cannot load library: /opt/ros/crystal/lib/librmw_fastrtps_cpp.so: undefined symbol: _ZTVN8eprosima8fastrtps27DataRepresentationQosPolicyE,

I will see if this can be solved by avoiding to actually install Fast-RTPS in the first place.

This is not an issue that's reproducible. I have both Fast-RTPS installed from source and from ROS binaries and use it without any issues. Closing.
