Compile error: Adafruit GFX libraries won't find Wire.h / SPI.h

See original GitHub issue

Hi, whenever I start a new project in Platform IO for ESP8266 or ESP32 using Adafruit GFX Library I get a bunch of compile errors. The libraries using Wire.h / SPI.h won’t find them, but they’re clearly there, I can use them in my main code.

_Sorry if this is the wrong place to report this issue, but I really don’t know if this is an issue with Adafruit GFX, ESP8266/ESP32 Platform in Plaform IO, Platform IO VSCode IDE, Platform IO Core or VSCode… I don’t want to spam all repositories with this. Already opened an Issue here: https://github.com/adafruit/Adafruit-GFX-Library/issues/307_

main.cpp

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

void setup() {
  Wire.begin();
}

void loop() {
  // put your main code here, to run repeatedly:
}

You don’t need to ignore them, you need to explicitly specify them as dependencies:

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
lib_deps =
    Adafruit GFX Library
    Wire
    SPI

Alternatively, you can add the following lines to your code so PlatformIO will detect dependencies automatically:

#include <Wire.h>
#include <SPI.h>

okay, so PlaformIO will detect that Wire/SPI etc is needed automatically if it is used in the main program, but not when used by libraries?

That’s true, that dependencies are probably hidden somewhere in the sources of external libraries, so the LDF is not able to detect them in default mode. You can control this behaviour by using other LDF modes https://docs.platformio.org/en/latest/librarymanager/ldf.html
