Hi there,
I'm trying to port the xmlbeansxx library
(sourceforge.net/projects/xmlbeansxx) under windows using "Borland C++
5.6.4". The thing is I am having trouble with the "enable_if"
construction. From the "config\compiler\borland.hpp", I know that the
bcc compiler do not support SFINAE trick and so the "enable_if" and like
constructions. In order to continue the port I have to modify the
"enable_if" implementation with something equivalent. Here is the code :
template
class cast_traits {
public:
TO operator ()(const FROM &from) const {
return (TO)(from);
}
};
class Ptr {
public:
template
static inline TYPE ptrFromThis(const boost::shared_ptr &from) {
TYPE n;
n.ptr = from;
return n;
}
};
/* (2) begin */
template
class cast_traits,
boost::is_base_and_derived
>
>::type
> {
public:
TO operator ()(const FROM &from) const {
TO r;
r.ptr = ptr_cast<typename TO::value_type>(from.ptr);
return r;
}
};
/* (2) end */
template
inline TO cast(const FROM &from) {
return cast_traits()(from);
}
My problem is with the "/*(2)*/" part of the code.
In the library code there is other constructions based on "enable_if"
but they are the same as the "/*(2)*/" example.
Thanks folks in advance. I'am really a newbie to boost (and templates)
and have no idea about a workaround.
PS: It is obvious that I will contribute the port to the xmlbeansxx project.
