ROS2 Humble Installation Error on MacBook Air M2 (Sonoma, 14.2.1, Apple Silicon)
In this article, we discuss the ROS2 Humble installation error on a MacBook Air M2 with the Sonoma 14.2.1, Apple Silicon operating system. By covering key concepts, we'll provide context around the issue and solutions.
Introduction to ROS2 and Apple Silicon
ROS2 (Robot Operating System 2) is a flexible framework for writing robot software. Apple Silicon, Apple's custom processors for Mac computers, are powerful and efficient, making them great for ROS2 development. This article focuses on installing ROS2 Humble on a MacBook Air M2 with the Sonoma 14.2.1 operating system.
Environment Setup and Installation
To ensure a successful ROS2 Humble installation, there are a few steps to follow before running the colcon build command.
- Step 1: Update your MacBook Air M2 by running the following commands in Terminal:
softwareupdate --list
softwareupdate --install --all
- Step 2: Install the Xcode Command Line Tools:
xcode-select --install
- Step 3: Install Rosdep, a ROS2 package manager:
sudo apt install -y python3-rosdep
- Step 4: Initialize Rosdep with the following command:
sudo rosdep init
rosdep update
ROS2 Humble Installation Error
Upon attempting to run the colcon build or colcon build --merge-install command, you might encounter the following error:
--- stderr: clang: error: unable to execute command: Segmentation fault: 11
Possible Solutions to the Error
To solve this issue, there are two possible solutions:
- Solution 1: Use the pre-built binaries from the ROS2 neoterminal repository:
First, clone the necessary repository:
git clone https://github.com/ros-guillaume/ros2_neoterminal.git -b humble
Then, run the following commands:
cd ros2_neoterminal
source install/local_setup.bash
colcon build --merge-install
- Solution 2: Build ROS2 Humble with custom compiler flags:
Set the following environment variable:
export CXXFLAGS="-Qunused-arguments"
Before running the colcon build or colcon build --merge-install command:
colcon build --cmake-force-configure
Now, you should be able to run the colcon build or colcon build --merge-install command without encountering the error.
Summary
- The ROS2 Humble installation error on a MacBook Air M2 with Sonoma 14.2.1 and Apple Silicon can be solved by using pre-built binaries from the ROS2 neoterminal repository or by building ROS2 Humble with custom compiler flags.
