Linking completely breaks on 3.0.0(-rc1)

Board

Version

latest development Release Candidate (RC-X)

IDE Name

Arduino CLI

Operating System

Linux (rolling release, up-to-date)

Description

When building a project when using 3.0.0 (in order to make use of the new ledcAttach function) it seems to fail with linking the majority of functions.

I have attached verbose build logs (and the build command) compiling with 2.0.11 vs 3.0.0-rc1.

arduino-cli compile -v --export-binaries --libraries=editor/arduino --build-property compiler.c.extra_flags="-Ieditor/arduino/src/lib" --build-property compiler.cpp.extra_flags="-Ieditor/arduino/src/lib" -b esp32:esp32:esp32s3 editor/arduino/examples/Baremetal/Baremetal.ino

v3.0.0-rc1.buildlog2.txt
v2.0.11.buildlog.txt

Currently blocking: thiagoralves/OpenPLC_Editor#106

I have checked existing issues, online documentation and the Troubleshooting Guide

@rhysperry111 - It is not fully clear to me what is the issue. Please depict it further.

Arduino Core 3.0.0 has many breaking changes when compared to 2.0.x.
Most embedded project codes shall need to be changed in order to use the new 3.0.x Core.
There is some documentation about it:

https://docs.espressif.com/projects/arduino-esp32/en/latest/migration_guides/2.x_to_3.0.html

Regarding ledcAttach(), it is in the 3.0.x Core but not n the 2.0.x.

@SuGlider

It is not fully clear to me what is the issue. Please depict it further.

The project compiles and links perfectly fine in v2.0.x (apart from the ledcAttach bit, but that's expected), however under v3.0.0 it fails to even link things like micros() (part of the standard set of Arduino functions). I have attached debug logs of the compilation/linking process that further describe what is happening.

[SuGlider]

OK, so the issue happens when using arduino-cli compile -v --export-binaries --libraries=editor/arduino --build-property compiler.c.extra_flags="-Ieditor/arduino/src/lib" --build-property compiler.cpp.extra_flags="-Ieditor/arduino/src/lib" -b esp32:esp32:esp32s3 editor/arduino/examples/Baremetal/Baremetal.ino building process.

Reading the logs, I think that it would be good to clear all cache, compiled binary folders, etc and start a new fresh build for Core 3.0.0.

There are many changes in IDF, library folders and others that may be picking up remainings binaries from 2.0.14 and using it to link the 3.0.0 version.

[rhysperry111]

I've cleared as many caches as I can find, and also 2.0.11 isn't mentioned once in the verbose log so I don't think it's a problem with some old components being left behind.

maybe @me-no-dev may take a look into the logs and quickly see the issue related to using arduino-cli to build it...

[rhysperry111]

I'd provide the source files if I could, but the files OpenPLC generates tend to be a bit of a mess and scattered over a few locations

[me-no-dev]

You are overwriting some things that we use: https://github.com/espressif/arduino-esp32/blob/master/platform.txt#L66-L67

Just add those to your custom extra flags and it should be fine

[rhysperry111]

Holy crap you're a lifesaver <3

Thanks for solving the issue, it's genuinely appreciated

Is this worth mentioning in the migration guide since it seems to have changed behavior since the 2.0.x releases?

[me-no-dev]

Sure thing! @VojtechBartoska please make sure this ends up in the migration guide. cc @P-R-O-C-H-Y @lucasssvaz

Reopening to remind us that documentation update is needed.

I had open an issue about it... #9566

[VojtechBartoska]

Lets close both issues with new PR with docs update.
