Issues with building the RTAB-Map for ros2 humble

[minato_99]

Hello matlabbe,

I am following https://github.com/introlab/rtabmap_ros link to install rtabmap (source) for for ros2 humble. My system is getting frozen whenever it starts building rtabmap_sync. I was wondering what could be the subtle solution.


Sincerely,

You may run out of RAM. The trick is to build less files in parallel. Like the example on "Build from source" section here, set

export MAKEFLAGS="-j1"

This will create only one compilation process per package. You can also limit the number of packages built in parallel with:

colcon build --executor sequential
or
colcon build --parallel-workers 1
