Thanks a bunch! Checked library : with gcc it works, with g++ not, saing about undefs. I assume there need some C++ guards as usually inside of libwprinf.h ? Maybe forgotten extern "C" or something ?

Change the libwprintf.h header to:


#ifndef LIBWPRINTF_H

#define LIBWPRINTF_H



#include <stdio.h>

#include <stdarg.h>

#include <wchar.h>



#ifdef __cplusplus

extern "C" {

#endif



int swprintf(wchar_t *buffer, size_t maxlen, const wchar_t *fmt, ...);

int vswprintf(wchar_t *buffer, size_t maxlen, const wchar_t *fmt, va_list ap);



int fwprintf(FILE *fp, const wchar_t *fmt, ...);

int vfwprintf(FILE *fp, const wchar_t *fmt, va_list ap);



#ifdef __cplusplus

}

#endif



#endif

and it will work with C++ too.

As I code mainly in plain C I tend to forget such things.
