Board

esp32

Device Description

TTGO T8

Hardware Configuration

Build error

Version

other

IDE Name

idf

Operating System

Ubu 22.04

yes

Upload speed

doesn't matter

Description

Hey come on can't you set up a template for build errors

---

using git commit 090bc7242cfd597a370d5eb711618b1dd3a0bee8

Arduino as a component

I have

CONFIG_LWIP_IPV6=n

in my sdkconfig.defaults and everything worked fine till I added arduino as a component in esp-idf v5.1.2-691-g7380f96017

Now I cannot compile the project. Removing the abusing line in the settings resolves the issue.

---

I opening the issue here because the error occurs while building arduino-esp32

Sketch

doesn't matter

Upcoming Arduino 3.0.0 needs IPv6 support enabled.

[dizcza]

all right

this is really annoying since IPv6 use 7KB of RAM as described by Espressif documentation :
https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-guides/lwip.html#lwip-ram-usage

really no plan to make it optionnal ?
