setup.bash is missed during creating customer MicroROS static library

[weblxj]

Dear man,

I have tried to run below command according to the official document to "create custom MicroROS static library". Unfortunately there is below exception. Just want to know what's the possible reason for this issue?

super@u20base:/microros_ws$ ros2 run micro_ros_setup build_firmware.sh $(pwd)/my_custom_toolchain.cmake $(pwd)/my_custom_colcon.meta
Crosscompiled environment: cleaning path
/home/super/microros_ws/install/micro_ros_setup/lib/micro_ros_setup/build_firmware.sh: line 65: /home/super/microros_ws/firmware/dev_ws/install/setup.bash: No such file or directory
super@u20base:/microros_ws$

Thanks a lot!

Here's the documentation for static library generation:

https://github.com/micro-ROS/micro_ros_arduino#how-to-build-the-precompiled-library

The following command generates static libraries (ROS2 humble) for all platforms:

$ docker pull microros/micro_ros_static_library_builder:humble

$ git clone https://github.com/wuhanstudio/micro_ros && cd micro_ros
$ docker run -it --rm -v $(pwd):/project --env MICROROS_LIBRARY_FOLDER=extras microros/micro_ros_static_library_builder:humble

I will try it will docker later.

Currently, I have followed the instructions here https://micro.ros.org/docs/tutorials/advanced/create_custom_static_library/ to do the building.

In the last step,:
ros2 run micro_ros_setup build_firmware.sh $(pwd)/my_custom_toolchain.cmake $(pwd)/my_custom_colcon.meta

I ran into some issues like below:

Appreciate it if someone can tell me what's the root cause of this issue and how to resolve it.

More details like below:
