Can't build first PlatformIO project - Adafruit Watchdog problem?

#1

I’m converting a project I wrote in the Arduino IDE to PlatformIO, and running into problems. I’ve stripped the project down for an example to show that it won’t build. I think it’s due to the Adafruit IO Arduino library pulling in the SleepyDog library as a dependency, which isn’t being done in Arduino IDE?

Is there any way to force PlatformIO to not include SleepyDog, even though it’s listed as a dependency, since the code does work in Arduino IDE? Or do I need to do something else differently?

platformio.ini:

[common]
platform = espressif8266
build_flags = 
    -D VERSION=0.1.0
    -D DEBUG=1
lib_deps_external = 
    Adafruit SSD1306@^2.3.1
    Adafruit BME280 Library@^2.0.2
    Adafruit IO Arduino@^3.7.0
[env:esp12e]
platform = ${common.platform}
board = esp12e
framework = arduino
; Build options
build_flags = 
    ${common.build_flags}
    -D WIFI_SSID=\"myssid\"
    -D WIFI_PASS=\"mypassword\"
    -D IO_USERNAME=\"myusername\"
    -D IO_KEY=\"mykey\"
; Library options
lib_deps = 
    ${common.lib_deps_external}

main.cpp:

#include <Arduino.h>
#include <Adafruit_BME280.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include “AdafruitIO_WiFi.h”

AdafruitIO_WiFi io(IO_USERNAME, IO_KEY, WIFI_SSID, WIFI_PASS);

void setup() {

}

void loop() {

}

The build shows SleepyDog as a dependency for Adafruit IO:

|-- <Adafruit IO Arduino> 3.7.0
| |-- <Adafruit MQTT Library> 1.3.0
| | |-- <Adafruit SleepyDog Library> 1.3.2
| | |-- <Adafruit FONA Library> 1.3.8
| | |-- <WiFi101> 0.16.0
| | | |-- <SPI> 1.0

Then I start getting failed builds for SleepyDog:

Compiling .pio\build\esp12e\lib8c7\Adafruit SleepyDog Library\utility\WatchdogAVR.cpp.o

After lots more googling, it looks like you can just exclude the libraries in the platformio.ini file like this:

lib_ignore =
Adafruit SleepyDog Library
WiFi101
ESP32Servo
Ethernet
