Can I enable verbosity in PX4 make output?

I am struggling to understand how various parts of the image are created.
Here are a few examples:

  1. How is builtin_list.[ch] created?
  2. How is the /etc/init.d/rcS file created?


I know I can set VERBOSE=1 and also make V=1; but is there any other tricks that can be used so that I can log the output of make and then see what’s actually being done?
Right now the best I can do is:
export VERBOSE=1; make V=1 2>&1 | tee make.out
Any suggestions? Is there any documentation that gives some detail on this?

You might get a better answer sooner on github.
There is a specific issue category for questions.

Thanks, I’ve never used this.
Are you talking about here: Issues · PX4/PX4-Autopilot · GitHub ?

The opening text in that “Issue: Support Questions” message box says:

We use GitHub issues only to discuss PX4 bugs and new features. For
questions about using PX4 or related components, please use PX4 Discuss.

I’ll post there and see if I get yelled at. :slight_smile:

It’s a build question so I don’t think they will mind.
Perhaps is will be a new build feature :-).

I feel your pain, but never thought to ask this question. Call me cynical, but the only accurate documentation also executes.

ROMFS/px4fmu_common/init.d[-posix] is the origin of /etc/init.d.

For built-in apps, see PX4-Autopilot/CMakeLists.txt at 4e3d944f58f0d60e072641fc60b426fbcfdad8ab · PX4/PX4-Autopilot · GitHub

I hope you get an answer for your general question.

ROMFS/px4fmu_common/init.d[-posix]is the origin of/etc/init.d

Yea I saw these. I ignored them because none were the same size as what is on my target; however, I just realized that they actually do match… the one on-target just has all empty lines and comments removed. Tx!

Thanks, I’ll have to dig into that. Shamefully I’m not much of a cmake expert (or ninja for that matter). :frowning:

If I learn anything from the github question, I’ll post it here for reference.

Well, cmake is so so you don’t have to know anything about ninja, except to set your makeprg alias to it.

Good luck!

The code in v1.12.0’s version (I’m stuck there for now) of that CMakeLists.txt file is substantially different. In both cases though they use the variable module_libraries which isn’t defined or used anywhere else. Where does that come from?
The fundamental problem I have (aside from needing to learn cmake) is that it appears that the builtin_list.h is created from the project-specific default.cmake file; however there are builtins in my running system that are not in that file and I need to understand where they came from (particularly sercom).

Replying to my own question just in case someone else may benefit…
dagar posted some good information here:
