Build Error when split code to multiple files

Hi everyone, i want to split my code to multiple files as helper functions like bellow and i want to specified 2 different main file when upload code to 2 board (esp8266 and arduino uno) :

image
image194×655 6.86 KB

the “constant.h” is where i define pin ports, “customlibs.h” and “extralibs.h” are where i include my own functions and extra library like:

#ifndef EXTRALIBS_H
#define EXTRALIBS_H

#include <Arduino.h>
#include <LiquidCrystal_I2C.h>
#include <Wire.h>
#include "constants.h"
#include <Servo.h>  
#include <Adafruit_Sensor.h>
#include<DHT.h>    

#endif // CUSTOMLIBS_H

here is my plaformio.ini file:

[platformio]

src_dir = ./

default_envs = esp8266

[env]

lib_extra_dirs = ./lib

[env:esp8266]

framework = arduino

platform = espressif8266

board = esp12e

lib_deps =

marcoschwartz/LiquidCrystal_I2C@^1.1.4

adafruit/DHT sensor library@^1.4.4

adafruit/Adafruit Unified Sensor@^1.1.9

build_src_filter = +<*>-<arduino.cpp>

[env:arduino]

platform = atmelavr

board = ATmega328P

framework = arduino

and i got this error when build:

 5 | #include <LiquidCrystal_I2C.h>
      |          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Please help me!!!

  1. u didnt paste all the error message
  2. src_dir = ./ is wrong → remove it
  3. lib_extra_dirs is deprecated and i think wrong in here → remove it
  4. for [env:esp8266] you have defined build_src_filter = +<*>-<arduino.cpp>, while you have not defined it for [env:arduino] → isn’t this obviously wrong?

thanks for replying, i edited my code like u said:
// platformio.ini
[platformio]

default_envs = esp8266

[env:esp8266]

framework = arduino

platform = espressif8266

board = esp12e

lib_deps =

marcoschwartz/LiquidCrystal_I2C@^1.1.4

adafruit/DHT sensor library@^1.4.4

adafruit/Adafruit Unified Sensor@^1.1.9

build_src_filter = +<*>-<arduino.cpp>

[env:arduino]

platform = atmelavr

board = ATmega328P

framework = arduino

build_src_filter = +<*>-<esp8266.cpp>

but i still throw errors:

that was full error message

Oh, I found out why there are the errors, because the librabry marcoschwartz/LiquidCrystal_I2C@^1.1.4 #include “Wire.h” but it cant found Wire.h in anywhere. I just removed that library because it is temporary unnecessary but do you have solutions to fix that ??

Wire.h is built into the Arduino core. If it can’t find it, best to verify that 1. you include the LiquidCrystal_I2C header file in your main code and 2. change lib_ldf_mode if neded.
