Issue with library under MacOs VSCode when using multiple configuration file

Libraries

Dear,
I’m coding a multiple configuration files for Arduino dev. When building, I’ve got many error concerning libraries…
Please find hereafter the .ini file and my source file.

Thanks a lot for your support.

; PlatformIO Project Configuration File

;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags

[env]
platform = atmelavr
board = uno
framework = arduino
lib_extra_dirs = ~/Documents/Arduino/libraries
lib_ldf_mode = chain+

[env:projet2]
platform = atmelavr
board = uno
framework = arduino
lib_extra_dirs = ~/Documents/Arduino/libraries
build_src_filter = +</Users/florenttainturier/Fablab-Escape/fablabescape/Fabrication/EscapeMain-TestServo/src/projet2>

[env:projet1]
platform = atmelavr
board = uno
framework = arduino
lib_extra_dirs = ~/Documents/Arduino/libraries
build_src_filter = +</Users/florenttainturier/Fablab-Escape/fablabescape/Fabrication/EscapeMain-TestServo/src/projet1>

And one of my example test :slight_smile:

#include <Wire.h>

void setup() {
  Wire.begin(8);                // join i2c bus with address #8
  Wire.onRequest(requestEvent); // register event
}

void loop() {
  delay(100);
}

// function that executes whenever data is requested by master
// this function is registered as an event, see setup()
void requestEvent() {
  Wire.write("hello "); // respond with message of 6 bytes
  // as expected by master
}

Does the issue also happens, if you remove this line from all environments in your platformio.ini ?

There are also two issues with this code.
You missed to include Arduino.h:

#include <Arduino.h>

You need to pre-declare requestEvent before you can use it in setup():

void requestEvent();

void setup() {
  Wire.begin(8);                // join i2c bus with address #8
  Wire.onRequest(requestEvent); // register event
}

Here is the complete code:

#include <Arduino.h>
#include <Wire.h>

void requestEvent();

void setup() {
  Wire.begin(8);                // join i2c bus with address #8
  Wire.onRequest(requestEvent); // register event
}

void loop() {
  delay(100);
}

// function that executes whenever data is requested by master
// this function is registered as an event, see setup()
void requestEvent() {
  Wire.write("hello "); // respond with message of 6 bytes
  // as expected by master
}

You can keep the platformio.ini much simpler:

[env]
platform = atmelavr
board = uno
framework = arduino

[env:project1]
build_src_filter = +<project1>

[env:project2]
build_src_filter = +<project2>

File and folder structure:

.
├── include
├── lib
├── src
│   ├── project1
│   │   └── main.cpp
│   └── project2
│       └── main.cpp
├── test
└── platformio.ini

Note: please try to avoid lib_extra_dirs = ~/Documents/Arduino/libraries
This leads to problems with a probability of 99.9%.

Use lib_deps for external libraries: lib_deps — PlatformIO latest documentation

Dear @sivar2311 , thanks for your advice. I will try next week the setup (I have no more access to my laboratory for few days).

Note : Previously , I was using the same code but without multiple configuration and I was able to build my code.

Dear @sivar2311 Finally I succeeded to test something before leaving. I have modify my code with your proposal (thank you much).

Unfortunately, here are my new errors :slight_smile:

Can you share the complete project?
Upload on github or as zip via a file hoster.

Dear, please hereafter the complete doc.
Note : the original project is a fork and I am refactoring all the code. So sorry for the aspect of the repository.

You are using the wrong file extention!

Rename your source files from .c to .cpp.
