Question about clang compile

Hi, I found that there is a docker named “px4-dev-nuttx-clang”.
It looks like px4 supports clang compilation for pixhawk board (e.g., pixhawk1)

However, I don’t know how to compile px4 (running on nuttx and pixhawk 1) with clang.
Could you help me solve this problem?

I took many different approaches.
The most promising one that I took was as follows: (w/ px4 1.9.2)
I first set PX4_DOCKER_REPO=“px4io/px4-dev-nuttx-clang:2019-03-08” in Tools/docker_run.sh.
Then, I run “./Tool/docker_run.sh ‘make px4_fmu-v2_default’”

Thank you

Compilation using clang is only possible for Linux x86 and maybe macOS but not for the STM32 targets like Pixhawk. For STM32 targets we use the arm-none-eabi toolchain. I don’t know if there is an equivalent toolchain based on clang.
