symbol lookup error on jazzy-testing

[christophfroehlich]

Since last night we get strange errors in all ros2_control jazzy-testing CI jobs, e.g. here. Is this known already, is this the right place here to report?

Python tests

[spawner-3] /usr/bin/python3: symbol lookup error: /opt/ros/jazzy/lib/libcontroller_manager_msgs__rosidl_typesupport_fastrtps_c.so: undefined symbol: _ZN8eprosima7fastcdr3Cdr9serializeERKh

c++ tests

/home/runner/work/ros2_control_ci/ros2_control_ci/.work/target_ws/build/realtime_tools/realtime_server_goal_handle_tests: symbol lookup error: /opt/ros/jazzy/lib/libtest_msgs__rosidl_typesupport_fastrtps_cpp.so: undefined symbol: _ZN8eprosima7fastcdr3Cdr9serializeEa

clang also complains on rolling at build time

  /usr/bin/ld: /opt/ros/rolling/lib/libtest_msgs__rosidl_typesupport_fastrtps_c.so: undefined reference to `eprosima::fastcdr::Cdr::serialize(signed char)'

However, here it seems to be fine
https://build.ros2.org/job/Jbin_uN64__rosidl_typesupport_fastrtps_cpp__ubuntu_noble_amd64__binary/

Required Info:

• Operating System:
  • ubuntu noble
• Installation type:
  • binary
• Version or commit hash:
  • jazzy testing
• DDS implementation:
  • fastrtps
• Client library (if applicable):
  • N/A

@marcoag FYI

I think this might be my fault. The last release of fastcdr includes one change that might be an ABI break, which I didn't realize.

The failures seem to have started to happen when ros/rosdistro#43968 and ros/rosdistro#43967 were merged

I think this is due to eProsima/Fast-CDR#210, where some exported methods changed from being implemented in the header to the source.

I suggest to bloom-release fastcdr v2.2.5, and fix the .repos to that version while we are on holidays.

This issue has been mentioned on ROS Discourse. There might be relevant details there:

@MiguelCompany are you guys blooming v2.2.5 anytime soon or shall I take care of it?

[MiguelCompany]

@marcoag Almost all of us are on holidays. Would be great if you can take care of it.
