Is it possible to change the logger, spdlog to log4cxx, without having to rebuild individual ros packages?

Unfortunately you'll need to rebuild rcl. rcl picks the logger to use at compile time, which by default is rcl_logging_spdlog.

Add rcl_logging_log4cxx and rcl to your workspace, then choose the logging implementation by setting the environment variable RCL_LOGGING_IMPLEMENTATION.

export RCL_LOGGING_IMPLEMENTATION=rcl_logging_log4cxx
colcon build --cmake-clean-cache --packages-select rcl_logging_log4cxx rcl
