verbose makefile argument via cmake not working as expected

[PeterMitrano]

I would expect the following command to print verbose makefile output, as if I invoked make VERBOSE=1, but instead it does not print anything besides the normal colcon output.

colcon build --cmake-args -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON --packages-select Gazebo

Apologies if this is the wrong colcon repo!

If you have colcon-output installed by default you won't see any stdout output of the build process. Only stderr output is printed by default.

Have you looked in the log file (log/latest_build/Gazebo/stdout.log) if it contains the information you are expecting?

As an alternative you can change the output by passing e.g. --event-handlers console_cohesion+ to output all stdout output once a package finished. Or in the case you are building only a single package even stream the output when it comes in: --event-handlers console_cohesion+.

Yep, that's what I was looking for. Thanks!
