I've found a strange solution...
Now my rpogram looks like:
------------8<-------------
#include <iostream.h>
#include <_Complex.h>
int main(void) {
Complex j (0,1);
cout << "hello world!\n";
return 0;
}
------------8<-------------
The source code is no more portable.
Borland C/C++ doesn't have the "_Complex.h" header file and there is no
class with name "Complex" in "complex.h".
Watcom C/C++ has no the "_Complex.h" header file but have a typedef that
makes "complex" the same as "Complex".
What's going on?
:((((((((((((((((((((((((((((((((((((((((
I'm starting to think that:
- I'm a fool that understands nothing
- I'm an idiot trying to solve all the problems I ever encounter with DJGPP
- I try to use things used pretty seldom by other people, so I have problems
- I'm just unlucky
:((((((((((((((((((((((((((((((((((((((((
Please explain me the purpose of these include/header files from the
"djgpp/lang/cxx" directory:
------------8<-------------
// file name: //
// complex //
// Main header for the -*- C++ -*- complex number classes.
// This file is part of the GNU ANSI C++ Library.
#ifndef __COMPLEX__
#define __COMPLEX__
#include <std/complext.h>
extern "C++" {
#define __STD_COMPLEX
// ANSI complex types
typedef complex<float> float_complex;
typedef complex<double> double_complex;
typedef complex<long double> long_double_complex;
}
#endif
------------8<-------------
------------8<-------------
// file name: //
// complex.h //
// -*- C++ -*- backward compatiblity header.
// Copyright (C) 1994 Free Software Foundation
#ifndef __COMPLEX_H__
#include <complex>
#endif
------------8<-------------
------------8<-------------
// file name: //
// _Complex.h //
// This may look like C code, but it is really -*- C++ -*-
#ifndef _Complex_h
#define _Complex_h
// Use the ANSI complex number template.
#include <complex>
typedef complex<double> Complex;
#endif
------------8<-------------
