The following code fail to compile under cygwin. The relevant error message is:
...: undefined reference to `Base::x'
collect2: ld returned 1 exit status
However if I change the statement "y=-x" to "y=x", then it compiles fine.
class Base
{
public:
virtual void f () = 0;
static const double x = 1;
};
class Derived : public Base
{
public:
Derived () {};
void f () { double y = -x; };
};
int main()
{
Derived foo;
return 0;
}
