Building Micro-XRCE-DDS Agent fails with clang #54
Description
Describe the bug
When building the micro-ROS Agent for ROS 2 Rolling on Ubuntu 20.04, I received a build error during the build of the Micro-XRCE-DDS Agent.
To Reproduce
- Follow the tutorial in https://micro.ros.org/docs/tutorials/core/first_application_linux/, but with
rolling(or rathermain) instead offoxy. - Builds fails in step
ros2 run micro_ros_setup build_agent.sh
The problem seems to be the use of a log function with a dds::xrce::TransportAddress type.

Just tried the tutorial under Foxy and ran into the same issue.

Hi Ralph, this night the CI has passed OK: https://github.com/micro-ROS/micro_ros_setup/runs/2127704213?check_suite_focus=true
I'm going to check this manually.

Hi @pablogs9, on a second machine (also Ubuntu 20.04 and ROS 2 Foxy) I could not reproduce the error - even after
apt update && apt upgrade. Very strange.ralph-lange commentedon Mar 17, 2021
Okay, I've found it: On the first machine I used clang not gcc.
pablogs9 commentedon Mar 18, 2021
Ok, closing since solved. Thanks Ralph.
ralph-lange commentedon Mar 18, 2021
I would not call this solved, since clang is also a widely used compiler.
pablogs9 commentedon Mar 18, 2021
@Acuadros95 could you test this compilation process using clang instead of gcc?

@ralph-lange Hi Ralph, clang couldn't find the formatter for the
dds::xrce::TransportAddresstype.We have just merged a solution for this issue here, the Agent build should be fine with clang now. I am closing the issue, let us know if you encounter further problems regarding this problem.

Thank you for fixing this issue, @Acuadros95
