Steps to reproduce the issue

Foxy is installed
I followed below method to install micro_ros_agent

mkdir -p ~/ros2_ws/src
cd ros2_ws/src
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_setup.git
git clone  https://github.com/PX4/px4_ros_com.git
git clone https://github.com/PX4/px4_msgs.git
cd ~/ros2_ws
colcon build
source install/local_setup.sh
sudo rosdep init
rosdep update
ros2 run micro_ros_setup create_agent_ws.sh
ros2 run micro_ros_setup build_agent.sh

Initially had issue with libfmt so I apt installed below
$ sudo apt install libfmt-dev libspdlog-dev

Expected behavior

Actual behavior

Does this branch fixes the issue eProsima/Micro-XRCE-DDS-Agent#345 ?

Does this branch fixes the issue eProsima/Micro-XRCE-DDS-Agent#345 ?

This issue resolved actually by setting UAGENT_USE_SYSTEM_LOGGER to ON. It was OFF before.

option(UAGENT_USE_SYSTEM_LOGGER "Force use of system installed spdlog logger on superbuild." ON)

Cool closed as solved

I revisited this package and still get error regard to fmt
either UAGENT_USE_SYSTEM_LOGGER is ON or OFF

I checked the version of spdlog as below.

$ sudo apt show libspdlog-dev
Package: libspdlog-dev
Version: 1:0.16.3-1
Priority: optional
Section: universe/libdevel
Source: spdlog
Origin: Ubuntu

Description: Very fast, header only, C++ logging library
 Features: Very fast - performance is the primary goal; Headers only; No
 dependencies - just copy and use; call style using the excellent cppformat
 library; ostream call style is supported too; Optional extremely fast
 asynchronous mode - using lockfree queues and other tricks to reach millions
 of calls/sec; Custom formatting; Multi/Single threaded loggers; Easily
 extendable with custom log targets (just implement a single function in the
 sink interface). Severity based filtering - threshold levels can be modified
 in runtime as well as in compile time.
 .
 Various log targets:
 Rotating log files, Daily log files, Console logging, Linux syslog.

How can I solve the issue?

This is issue resolved by source install spdlog from the git repository.
Latest spdlog is v1.15 and after install, it builds without error.
