The way to do it is to specify an explicit signature for the ctor and to
use %MethodCode...
typedef void *auto_ptr;
class Foo
{
public:
Foo(const char *) [(auto_ptr)];
%MethodCode
sipCpp = new sipFoo(some_static_method(a0));
%End
};
The only odd thing here is the auto_ptr typedef which is needed (although
never used in the generated code) because SIP needs to know a fundamental
type (but not necessarily the correct fundamental type) for every argument
of a C++ signature. I will change it so that the typedef isn't needed - but
it doesn't do any harm.
