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?

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 */
