Hi,
Just because the complex nature of a ROS setup, we will need to know more
about your environment and enable extra logging to help you with this.
Are you using Docker(if so please share Dockerfile)? What base OS version
are you using(officially ROS2 Humble only support Ubuntu22.04, other
version can cause unpredictable issues).
To collect extra log, please help me with the following:
Use ROS2 Logging, execute line by line in the same folder you build
custom_handler:
export RCUTILS_CONSOLE_OUTPUT_FORMAT="[{severity}] [{time}] [{name}]:
{message}"
export RCUTILS_LOGGING_BUFFERED_STREAM=1
export RCUTILS_LOGGING_USE_STDOUT=1
export RCUTILS_CONSOLE_STDOUT_LINE_BUFFERED=1
RCUTILS_LOG_MIN_SEVERITY=DEBUG ./custom_handler
Use strace:
strace -f ./custom_handler 2>&1 | tail -50
Use ldd: ldd ./custom_handler | grep "not found"
Hopefully one of these will yield some insights, please upload the info
generated by each debugging step, if not we will go the core dump analysis
route.
libconsole_bridge.so is mainly used for ROS2 logging purposes, though it
should not happen, it shouldn't be catastrophic and cause a segfault
either. We will see if ldd points to this.
Best,
Patrick Chen
