The g++ compiler version and machine information are as follows:

Here is a simple testcase:
#include <ios>
template <typename T>
class A: public std::locale::facet
{
public:
const char* a1;
void f(){
a1 = std::locale::facet::_S_get_c_name();
//a1=_S_get_c_name(); <- this line also gives the same error.
}
};
int main()
{
A<int> obj;
obj.f();
}
Compiling the testcase with g++ compiler, I am getting the linking error:
/tmp/ccM4h5sR.o(.gnu.linkonce.t._ZN1AIiE1fEv+0x20): In function `A<int>::f()':
: undefined reference to `std::locale::facet::_S_get_c_name()'
collect2: ld returned 1 exit status
The problem is the static member function _S_get_c_name() which is declared in
the <bits/locale_classes.h> is not defined.
