odas_ros (ROS2) in a Dockerfile

[kyle-redyeti]

I have been trying to set up odas_ros from the ros2-migration branch and I keep getting errors when attempting to build
my Dockerfile looks like this:

"""
FROM ros:humble-ros-base
RUN apt update && apt upgrade -y
RUN apt install -y git-all cmake gcc build-essential libfftw3-dev libconfig-dev libasound2-dev libpulse-dev libgfortran-*-dev perl
RUN apt install -y python3-pip
RUN apt-get install -y gfortran texinfo

RUN /bin/bash -c 'source /opt/ros/humble/setup.bash &&
mkdir -p ~/ament_ws/src &&
cd ~/ament_ws/src &&
git clone -b ros2-migration https://github.com/introlab/audio_utils.git &&
pip install libconf &&
cd audio_utils &&
git submodule update --init --recursive &&
cd ~/ament_ws/src &&
git clone -b ros2-migration https://github.com/introlab/odas_ros.git &&
cd odas_ros &&
git submodule update --init --recursive &&
cd ~/ament_ws &&
source /opt/ros/humble/setup.bash &&
rosdep install --from-paths src -i -r -n -y &&
colcon build &&
source install/setup.bash'

ADD config/respeaker_usb_4_mic_array.cfg ~/ament_ws/src/odas_ros/config/configuration.cfg
"""

It seems to fall apart trying to build audio_utils...

Oh... and I am trying to build and run the docker container on a RaspberryPi 5

Thanks!

The ros2-migration branch was a work in progress. Can you try again using the new ros2 branch? Also, make sure to use the ros2 branch for audio_utils too.
