Describe the bug
I'm trying to go through the "first application linux" tutorial, but am getting a build error that is preventing the micro_ros_agent from finishing its build.

To Reproduce

  1. System Description:
    -Ubuntu 20 running in a VirtualBox with windows 10 host
    -Installed ROS2 Foxy using standard install procedure, confirmed working with pub/sub example
  2. Followed all steps here: https://micro-ros.github.io/docs/tutorials/core/first_application_linux/ (Not using the docer method)
  3. On running this step: --> $ros2 run micro_ros_setup build_agent.sh
    Output:

    Finished <<< microcdr [0.30s]

    Good morning,
    I'm afraid we would need more details about which specific Ubuntu image you mounted using VirtualBox and double check if you missed some of the commands in the tutorial. For me, it is working as expected, running on a Ubuntu 20.04 Focal Docker container.
    That being said, this error seems to be related to some fmt library missing on your system. Did you try:

    sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install libfmt-dev

    , then recompiling the agent with the steps provided? The only thing in the agent that is using some headers related to this library is the logger, to display information about the agent's status in the screen.

    Hey,
    Even I'm facing the exact same error. I just saw the issue here(after posting it myself here) and tried the solution you suggested, to download fmt lib. But still, the error persists. It'll be really helpful if you can look into it, and please let me know if you need something else.

    Same error for me on Ubuntu 20.04.2 LTS even after executing the suggested commands to install fmt.

    I am now able to build and execute the agent (not using the docker container).

    There are several ROS2 official install tutorials and they appear to install/source ROS2 differently thus breaking the micro-ros-agent build process.

    My process:
    Install Ubunutu 20.04.

    Install ROS2 via Debian packages (I installed the desktop version): https://docs.ros.org/en/foxy/Installation/Ubuntu-Install-Debians.html

    Install rosdep2: sudo apt install python3-rosdep2

    Install colcon: sudo apt install python3-colcon-common-extensions

    Install micro-ros: https://micro.ros.org/docs/tutorials/core/first_application_linux/

    I am really excited to get micro-ros working with my project, thanks for the hard work!

    I tried the suggestion by @jamoralp and it says libfmt-dev is already the newest version (4.0.0+ds-2). 0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded.

    Can someone help me?

    We just added a flag to use the system version of spdlog: eProsima/Micro-XRCE-DDS-Agent#303 and #118

    Agent build should succeed with this flag enabled:
    colcon build --cmake-args -DUAGENT_USE_SYSTEM_LOGGER=ON

    I solved this on my horizon rdk x3 arm board, by compile a 6.x version fmt. I'm using ubuntu 20, and I compiled fmt-6.1.2.

    wget https://github.com/fmtlib/fmt/archive/refs/tags/6.1.2.zip
unzip 6.1.2.zip
cd fmt-6.1.2
mkdir build && cd build && cmake .. && make -j4
sudo make install

    I compiled and installed fmt just before ros2 run micro_ros_setup build_agent.sh by the way.
