solution for keyword "uuidof" of g++ ?

[William]

g++(mingw) doesnt support keyword "uuidof" on win32 platform ,
is there any solution to solve it ?

thanks !

Write your own, it isn't a standard C++ keyword or library function.

Off the cuff (not tested):

typedef std::string Uuid; // Whatever, this is just an example.

template< class T >
Uuid const& uuidFor()
{
return T::uuid(); // General.
}

struct A
{
static Uuid const& uuid()
{
static Uuid id const = "Aha!";
return id;
}
};

struct B {}; // Might be some existing class.
Uuid const uuidForB = "Bah!";
template<Uuid const& uuidFor<B>() { return uuidForB; }

int main()
{
using namespace std;
std::cout << uuidFor<A>() << std::endl;
std::cout << uuidFor<B>() << std::endl;
}

There is no "uuidof" in standard c++.

is there any solution to solve it ?

Since your question concerns something outside the scope of C++ as defined
by its standard, this news group is the wrong place for your question.
Maybe folks in a windows group might know.

Don't be blinded by the OP's mention of 'win32'.

UUIDs are used on all common platforms.

The problem of associating them with classes is a general problem easily
solved in standard C++, but then whoever invented the language extension
mentioned by the OP probably didn't find it easy or trivial.

No, we're not blinded by the win32 reference, we're OT'ing his query
about a Microsoft-specific language extension: namely that classes can
have an associated UUID, and there's a keyword -- not a function --
called "uuidof" to get said UUID.

it seems that 'wine' (a project to run window program on linux) has a way
to simulate 'uuidof'.
i am looking for this.

Top posting redacted. See the FAQ
http://www.parashift.com/c++-faq-lit...t.html#faq-5.4

That's still the MSVC compiler doing the uuid_of, and the fact that it's
compiler specific and NOT in the ISO Standard ISO/IEC 14882 makes it OT.

See http://www.parashift.com/c++-faq-lit...t.html#faq-5.9 for a
list of suggested newsgroups. In particular, since your question is
about g++, may I suggest gnu.g++.help?
