Private library not finding one of other private libraries

It seems one of my private libraries doesn’t find the otheR.

I have 3 private libraries:

  • The tft private library provides some adapting and basic UI elements over the TFT_eSPI library (from repository).
  • The logging - another private library (maybe some day could go public), basically 2 headers that provide simple macros like LOG_ERROR etc adapting depending on platform (Pico/ESP/Arduino/AVR)
  • The utils private library, stuffed with few random utils

The tft is only used from main code. Both the utils and logging should used by both main code AND tft - problem is, the LDF only finds utils while in tft context.

I tried:

  • adding lib_ldf_mode = deep to platformio.ini, not much changes.
  • adding #include <logging.hpp> to both hpp and cpp file from - also doesn’t help (just errors in header instead of source file due to includes ordering)

Why utils works but logging not? Werid.

Can you show the folder / file structure where youre files are located?

If it isn’t enough let me know. I can also tree -d the directory, but it’s a lot of files.

Have you tried deep+ ?

It looks like this is from your picOOscilloscope repo?
If so, can you push the latest version to the repo?

Solution 1

Using deep+ works for me. Thanks for your help and dedication.

Solution 2

I was thinking: Maybe the issue is because there is logging.hpp in both main files (src folder) and the logging private library? However, it shouldn’t be a thing, since private library compilation context shouldn’t even include main files, no?

So, I just tried renaming the file into anything else - and it also helps (working on deep, and even default chain LDF mode (if #include from header file)).

Why?

Now question “why?” remains. Looks like LDF is a bit bugged? I am not 100% why… For sure it’s annoying and undesirable behaviour. For now I will leave this issue/topic open I guess.

I will update the repo in like hour when I finish current commit - I am trying to split code from src into few private libraries, with hope that will ease testing. Again thank for your help & interest.
