Why my program doesn't compile using LwIP?

I'm trying to compile my program, but it doesn't work due to an error probably related to LwIP includes.

I've found online that there's a problem with LwIP's errno file.

https://community.nxp.com/t5/Digital-Signal-Controllers/I-did-not-compile-quot-Hello-World-quot-cpp-code-in-MCUXpresso/m-p/983807

Doesn't fix my problem at all, the output is no different.

Anyone know's the solution?

UPDATE:

Seems to be the issue... anyone able to help me?

Hello @Jvan .10 it seems from picture that header file is not properly included in project.

If Its possible you can share your project folder here to try.

Just add <sys/errno.h> at the beginning like:

#pragma once
 
#include <sys/errno.h>
#include <string>
 
#include "lwip/udp.h"

<sys/errno.h> define ENOTSUP and more

(169) #define ENOTSUP 134 /* Not supported */
