ESP32 - Arduino framework giving error in WiFi library

iomkar · April 3, 2021, 10:11am

Hello,

I am using Node mcu 32s board of ESP32 for development in platform io using arduino framework.
However I am getting following error on including WiFi library .

Verbose mode can be enabled via `-v, --verbose` option

How to resolve this issue ? Please help

my platformio.ini : -

[env:nodemcu-32s]
platform = espressif32
board = nodemcu-32s
framework = arduino
lib_extra_dirs = ~/Documents/Arduino/libraries

This doesn’t look good. Can you use the project task “Advanced → Verbose Build” and post the “Dependency Graph” section?

iomkar · April 3, 2021, 10:33am

Hello,
This is my dependency graph.

maxgerhardt · April 3, 2021, 10:37am

This seems to be causing problems. Why is there a library called include and what’s in there?

I see two possible solutions here:

remove that C:\Users\Omkar Inamdar\Documents\Arduino\libraries\include folder after checking what stuff is in there
do not include your old Arduino libraries folder, declare all libraries per lib_deps, per-project.

The only actual non-built in library you seem to be using is the RTClib, so your platformio.ini should look like

[env:nodemcu-32s]
platform = espressif32
board = nodemcu-32s
framework = arduino
lib_deps =
     adafruit/RTClib @ ^1.12.5

iomkar · April 3, 2021, 11:02am

Hello Max,
changing platformio.ini as per your suggestion worked.
include was containing other arduino libraries and removing that has resolved the issue.
Thank you so much!

Omkar
