Hi Mark & Tamas,
It is unlikely to be a problem with flags (-fPIC is for "position
independent code" so something that would come up at linking stage).
If you are getting zeros as the NULL template values the most likely
reason is that the template null hasn't been specialised for a type
that is being used. See the file:
ql/utilities/null.hpp
// BN: This is the un-specialised version which returns Type()
// which will be zero
//! template class providing a null value for a given type.
template <class Type>
class Null {
public:
Null() {}
operator Type() const { return Type(); }
};
// Specialised versions follow....
I suspect you need to add a specialisation for the size_t type since
on 64bit windows size_t is (I think) not the same type as unsigned
int.
Best,
Bojan
