How can I solve below template partial specialization problems?

I want to specialize template when return type is void.

==========================================

template <char const*& T, class U, class X>
class CSpecialize
{
public:
CSpecialize(X (U::*pfunc)())
: m_pFunc(pfunc)
{
}

X (U::*m_pFunc)();
};

template <char const*&T, class U>
class CSpecialize<T, U, void>
{
public:
CSpecialize(void (U::*pfunc)())
: m_pFunc(pfunc)
{
}
private:
void (U::*m_pFunc)();
};

compiler error message is

error C2755: 'CSpecialize<T,U,void>' : non-type parameter of a partial specialization must be a simple identifier

I thought so. But since you can't compile it in VS 2005, you should consider alternative ways.

thank you for your attention.

however, If I follow your answer, I must change program design. T.T

unfortunately, It's a greate job to me.

We don't have an exact date yet - but I can say that it won't be in 2006.

I can confirm that this is a bug in Visual C++ 2005. The problem is in the code that checks that the usage of a non-type template parameter in a partial specialization is correct (specifically checking 14.5.4/9). The use of the '*&' as part of the type of the non-type template parameter confuses the compiler. I have a fix for the issue.

a workaround for this problem is:

template <const char *& Reference>
class StringReference
{
public:
static const char* ref()
{
return Reference;
}
};

template <typename T, class U, class X>
class CSpecialize
{
......
};

now instantiate CSpecialize the following way:
//global
const char *t;
// local
CSpecialize<StringReference<t, class_u, class_x> mySpecialisation;

It is not currently available (it only exists on one enlistment on my machine). The fix will probably first see the light of day as part of the Orcas release.

its great that MS admits bugs. i really love that.

i do wish we could get more frequent service packs. we (out here) are making our living dependent on the compiler. is there a rough time frame for ORCAS

BTW ..... great great product (VS2005)

thanks

vs 2005 cann't compile it but gcc 4.0 can do it !!!

Can anyone help me

Comeau can also compile it.

Perhaps you can do this (which at least compiles):

template <char const*& T, class U, class X>

class CSpecialize

{

public:

CSpecialize(X (U::*pfunc)())

: m_pFunc(pfunc)

{

}

X (U::*m_pFunc)();

};

template <char const*&T, class U>

class CSpecializeDerive : CSpecialize<T, U, void>

{

public:

CSpecializeDerive(void (U::*pfunc)()):

CSpecialize(((void)(U::*m_pFunc))pfunc)

{

}

private:

void (U::*m_pFunc)();

};

And is that fix available Or will it be included in a future service pack
