Hello,

I'm working in MCUXpresso IDE 11.0.
I'm working in .cpp source file and generate a file with GNU C++ 11(-std=gnu++11) Standard toolchain.

I want to Build and compile basic hello world code with this toolchain.
I also try to modify Newlib and NewlibNano Library header but not solve my issue yet.

#include <iostream>

using namespace std;

int main()

{

cout << "Hello, World!";

return 0;

} Above code I want to compile.When I compile this code I got an error(Please find Attachment).

MIMXRT1062xxxxA_Project_CES_DEMO C/C++ Problem

How could I resolve this issue? Kindly give me a way.

I ran into this issue as well. The problem was that lwip's version of <errno.h> was being included instead of the standard c++ library version of <errno.h>. By any chance are you compiling with #include path's from lwip?

Yes,you are right.
When we create a new project at that time lwip/errno.h have only a single file include #include "lwip/errno.h".
So, our compiler finds errno.h in system file but not included in lwip/errno.h.

So, just replace following snippet from lwip/errno.h

#ifndef __ERRNO_H__
#define __ERRNO_H__
#include "lwip/errno.h"
#ifndef __error_t_defined
typedef int error_t;
#define __error_t_defined 1
#endif

#include <sys/errno.h>

#endif /* !__ERRNO_H__ */

Thanks for Support.
