That's already in the error:

Failed to load library: could not load library loadlibrary error: /home/mobile/dev_ws/install/ether_ros2/lib/libether_ros2_component.so: undefined symbol: _ztvn10ether_ros220ethercatcommunicatore

_ztvn10ether_ros220ethercatcommunicatore is the mangled version of the symbol.

I'm not sure why, but c++filt (which you'd normally use to demangle symbols) can't process it.

Is libethercat.so perhaps a C library, and did you perhaps forget to extern C the #includes of the accompanying header?
