I'm trying to cross-compile ROS2 Humble itself for Raspberry Pi 3 Model B.
My board is not new, it has 32-bit CPU and 1Gb of RAM. I have installed Ubuntu 22.10 server on it.
I have failed to find binary ROS2 packages for it and now trying to build them from source.
However, building on the Raspberry directly often fails, because a compiler exhausts RAM and OS kills it. I have installed ros_cross_compile tool and now trying to cross-compile ROS2 on my laptop. However, this tool tries to download packages instead of building them and fails.
Commands
mkdir -p ros2_humble/src
cd ros2_humble
vcs import --input https://raw.githubusercontent.com/ros2/ros2/humble/ros2.repos src
ros_cross_compile . --arch armhf --os ubuntu --rosdistro humble
Here is the tail of their output

It tries to install the packages with apt instead of building them.
This command is written in the file cc_internals/armhf-ubuntu-humble/install_rosdeps.sh. I've tried to edit it, however, ros_cross_compile tool overwrites it, and I cannot find how to make it to use my own file instead of generating it.
I have tried to submit my customized install_rosdeps.sh with --custom-rosdep-script flag, but it didn't help.
