Describe the bug
I have encountered Segmentation Fault while trying to run px4_sitl with jmavsim on Mac OS Big Sur.
To Reproduce
Steps to reproduce the behavior:
- Installed the PX4 Dev Toolchain based on PX4 Dev Guide
Though while running this commandbrew cask install xquartz java, I encountered this errorerror cask 'java' is unavailable. So, I used this command to install javabrew cask install adoptopenjdk/openjdk/adoptopenjdk8. - Clone the PX4 Repo
- To Run the SITL, I used the command
make px4_sitl jmavsimafter which I encountered this error-
