>Description:
gcc can't seem to generate the specialization in the example
code. It gives the error
simple.C: In function `int main()':
simple.C:25: no match for call to `(Tensor1<double>) (Index<'i'> &)'
KCC version 3.4 and IBM's Visual Age C++ v5.0 both compile
without complaints, so I'm reasonably sure that this is
allowed by the language.
If I get rid of either of the template<>'s, i.e. change
template <class T>
class Tensor1
to
class Tensor1
or change
template<char i>
double operator()(Index<i> &index)
to
double operator()(Index<'i'> &index)
then it compiles fine. But that doesn't give me the
functionality I need.
This may be a duplication of bugs 509, 72, and/or 45,
though they don't seem exactly the same.
>How-To-Repeat:
template<char i>
class Index
{
public:
Index() {};
};
template <class T>
class Tensor1
{
public:
template<char i>
double operator()(Index<i> &index)
{
return 2.0;
}
};
int main()
{
Index<'i'> i;
Tensor1<double> t1;
t1(i);
}
To compile, it's just
g++ simple.C
>Fix:
None known.
