Thread: Template function specialization

Hi folks.
The following code compiles fine with icc, however g++-3.3 issues "12: parse error before ';' token". What's wrong?

Code:

/*
 * simple test case for nested templates and template function specialization
 */

# include <iostream>

using std::cout;
using std::endl;

/**
 * Class template
 */ 
template< class T, int pT >
class A 
{
  public:
    static void function()
    {
        T::function< pT >(); // g++ does not like this line
    }
};

/*
 * Class with function template
 */
class B
{
  public:
    template< int pT > 
    static void function();
};

/*
 * For some reason, template function specialization may not occur in class definitions
 */
template< int pT > void B::function()
{
    cout << "unspecialized" << endl;
}

template< > void B::function< 0 >()
{
    cout << "specialized" << endl;
}


/*
 * Typedef to fake template function specialization in a class template
 */
typedef A< B, 0 > C;

/*
 * Putting it all together
 */
class D
{
  public:
    static void function()
    {
        C::function();
    }
};


int main() {

    D::function();

    return 0;
}

Code:

template< class T, int pT >
class A 
{
public:
	static void function()
	{
		T::template function< pT >(); //Now he likes it ;)
	}
}

Thank you so much

BTW - where does one get that syntactic knowledge? I've been looking in Stroustrup 3rd Ed and Deitel and Deitel 3rd Ed and I could not find anything in either book.

Danke, hab's jetzt in meiner englischen Version tatsaechlich auch gefunden.

Peinlich, peinlich.
