[ros-users] [Discourse.ros.org] [Next Generation ROS] How to set number of parallel jobs in ROS2 building?

[Dirk Thomas]

[quote="mlotfy, post:3, topic:3723"]
parallel build for each package is supported by the toolchain itself and that is what OP is asking about

Correct.

[quote="mlotfy, post:3, topic:3723"]
but parallel build for more than one package is not yet supported by ament
[/quote]

`ament build` has an option `--parallel` which also processes packages in parallel. There are known race conditions though (https://github.com/ament/ament_tools/issues/1450). We still use the feature on ci.ros2.org to speed up the builds. There is no configuration option to specify a limit for the packages processed in parallel.
