C++ template function problem, reply is appreciate!

[linarin]

How could I make this templates to work:

template<typename F,F f> //here f is non type template parameter
bool MethodProxy(int a,int b){ //could'nt change this function
return type and arguments.
return true;
}

template<typename F> //here F is a type of function object
void Def(F f){
static MyStruct global_methods[] =
{
{ "alert", JsProxyMethod<F,f> }, // error occur at here
NULL
} ;
//here do more works.
}

int alert(int a){
return 0;
}

int main(int argc,char* argv[]){
Def(alert); //when this function invoked, alert will be
executed.
return 0;
}



the error message is :
compiler complains that "f" not a valid argument and JsProxyMethod is
not a external linkage function.

There seems to be no use of 'F' or 'f' anywhere in this function. Are
you sure you need them?

return true;
}

template<typename F> //here F is a type of function object
void Def(F f){
static MyStruct global_methods[] =

What's 'MyStruct'?

{
{ "alert", JsProxyMethod<F,f> }, // error occur at here
NULL
} ;
//here do more works.
}

int alert(int a){
return 0;
}

int main(int argc,char* argv[]){
Def(alert); //when this function invoked, alert will be
executed.
return 0;
}



the error message is :

I am not sure it's possible to help you without seeing _real_ code
that produces that error message.
