Hi Jacek,
I would actually recommend that you try to compile the header file and
provide a dictionary for Complex<double>. The main advantage is that
you would then be able to pass the Complex<double> object back and forth
from the interpreter to compiled code. [You have a problem when
the interpreter knows about an 'interpreted version' of the Complex<double>
class and the compiled code knows about a 'compiled version'.
Philippe.

Subject: Re: [ROOT] root(cint) and template
Hi,
Thanks for your help. Indeed, replacing Complex by Complex<...> helped.
Now I get (root 3.00/06, RH6.1/i386) :
root [0] {#include "Complex"}
root [1] Complex<double> a(1.0, 2.0)
root [2] a
(class Complex<double>)141923096
root [3] cout << a
Error: Unexpected EOF G__fignorestream():3 FILE:Complext.hxx LINE:144
Advice: You may need to use +P or -p option
((const int)0
*** Interpreter error recovered ***
The code in question is :
template <class _FLT> inline _FLT
real (const Complex<_FLT>& x) __attribute__ ((const));
// (a completely empty line 144 is here ...)
template <class _FLT> inline _FLT
real (const Complex<_FLT>& x)
{
return x.real ();
}
where (previously, in the same file) :
#if ! defined (__GNUG__) && ! defined (__attribute__)
#define __attribute__(foo) /* Ignore. */
#endif
What now ?
Thanks in advance,
Jacek.
P.S. What I try to do is to get the template version of Complex class in
ROOT. The original code is taken from the GNU ANSI C++ Library. It
was modified to make sure that the real and imaginary part are stored
in contiguous elements of a two element array. This eliminates any
padding between the real and imaginary parts, allowing the class to
be later mapped correctly onto packed complex arrays (I hope). Jacek.
