Hi!

Trying yo apply changes in lwip library but I get an error (original error message in Spanish):

No se esperaba v6 en este momento. ---> Don´t wait V6 in this moment.

One hardly understands to which line of the Makefile this "v6" error refers to. This script is currently working with Linux. You are running windows, did you try to use WSL2 ?

I have in mind this option. I wil try.

Thank you!
