i've been trying to use and with PlatformIO for my "simple oled GUI". And i'm running into trouble including those libraries without any errors. Note that im a beginner in VScode and PlatformIO. Thanks in advance for any advice incoming :) Here is my code (not finished bcs of the issues):
#include <Arduino.h>
#include <Adafruit_SSD1306.h>
#include <Adafruit_GFX.h>
#include <Wire.h>
#include <SPI.h>
#define outputA 2
#define outputB 3
#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 64
#define OLED_RESET -1
#define SCREEN_ADRESS 0x3D
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
const int numpages = 3; //number of pages
int thispage = 0;
int counter = 0;
int aState = 0;
int aLastState = 0;
int textX0= 9;
int textY0 = 34;
int textX1 = 9; //default
int textY1 = 34; //default
int textY2 = 34;
int txtsize = 1;
void setup() {
pinMode (outputA,INPUT);
pinMode (outputB,INPUT);
Serial.begin (9600);
aLastState = digitalRead(outputA);
display.drawRect(4,22,121,19,WHITE); //Select rectangle
display.drawLine(7,42,1,1,848484); //Outline
}
void loop() {
aState = digitalRead(outputA); //Rotary encoder, saved into the "counter" variable
if (aState != aLastState){
if (digitalRead(outputB) != aState) {
counter ++;
} else {
counter --;
}
Serial.print("Position: ");
Serial.println(counter);
thispage = counter/2;
}
if(thispage < 0) {
thispage = numpages;
}else if (thispage > numpages){
thispage = 0;
}
textX0 = textX1;
textY2 = textY1;
textY2 = textY1;
if(thispage == 0){
textX0 = 6;
textY0 = 18;
textX1 = 9;
textY1 = 34;
textY2 = 56;
txtsize = 2;
}else{
textX0 = 9;
textY0 = 18;
textX1 = 9;
textY1 = 34;
textY2 = 56;
txtsize = 1;
}
display.setTextSize(txtsize);
display.setCursor(textX0,textY0);
display.setTextColor(WHITE);
display.print("menu1");
display.setTextSize(1);
display.setCursor(textX1,textY1);
display.write("menu2");
display.setCursor(textX1,textY2);
display.write("menu3");
display.print(thispage);
aLastState = aState;
display.clearDisplay();
}

I have consulted these errors with ChatGpt to no extent. I did everything this tutorial said, so i have g++, i can make a new project where and work, but i cannot use it with PlatformIO. I did edit the c_cpp_properties.json, but thats about it.
Here are the errors i have been talking about:

It looks like you are using an Arduino Uno or a similar devices. These devices do not have sufficient memory to implement the standard C++ string and IO classes. Thus, the Arduino people have created replacements that fit into memory.
So instead of std::string use String and instead of std::ostream use Stream (Serial is a Stream instance).
