Illegal Instruction on UTM M2 Apple Silicon

[w3ichen]

Environment

• OS Version: Ubuntu 20.04
• Source or binary build? Binary version libignition-math6-dev 6.15.1-1~focal

• UTM Virtual Machine Ubuntu 20.04 x86_64 emulation
• Ros1 noetic
• Gazebo11

Description

• Expected behavior: Runs without error
• Actual behavior: Illegal instruction SIGILL error, gzserver process has died, exit code 132

Steps to reproduce

1. Launching gazebo starts without error (ie. roslaunch husky_gazebo husky_playpen.launch)
2. Launching ros navigation stack and sensors causes the gazebo to error out (ie. roslaunch husky_viz view_robot.launch)

Output

Illegal instruction (core dumped)

I fixed this by building from source inside my UTM virtual machine, instead of using the binary from apt-get install.

1. I built from source according to these instructions on the ign-math6 branch.
2. Then replaced the .so file in /lib sudo cp at lib/x86_64-linux-gnu/libignition-math6.so.6 /lib/x86_64-linux-gnu/libignition-math6.so.6
