Summary: Duplicate function with smart pointer + static overload
Initial Comment:
The following code (test.i) run with:
swig -c++ -python
generates a duplicate _wrap_C_f function in test_wrap.cxx. I'm using
version 1.3.31 compiled with g++.
Swig prints a warning "Declaration of 'f' shadows
declaration accessible via operator->()" if static void f(int) is
removed. Adding %ignore C::operator->; fixes the problem but disables
the smart pointer functionality.
test.i
------------------------------
%module test
struct A
{
virtual void f();
};
struct B {};
struct C : public B
{
A* operator->();
static void f();
static void f(int);
};
------------------------------
The method table looks like this:
static PyMethodDef SwigMethods[] = {
{ (char *)"A_f", _wrap_A_f, METH_VARARGS, NULL},
{ (char *)"new_A", _wrap_new_A, METH_VARARGS, NULL},
{ (char *)"delete_A", _wrap_delete_A, METH_VARARGS, NULL},
{ (char *)"A_swigregister", A_swigregister, METH_VARARGS, NULL},
{ (char *)"new_B", _wrap_new_B, METH_VARARGS, NULL},
{ (char *)"delete_B", _wrap_delete_B, METH_VARARGS, NULL},
{ (char *)"B_swigregister", B_swigregister, METH_VARARGS, NULL},
{ (char *)"C___deref__", _wrap_C___deref__, METH_VARARGS, NULL},
{ (char *)"C_f", _wrap_C_f, METH_VARARGS, NULL},
{ (char *)"new_C", _wrap_new_C, METH_VARARGS, NULL},
{ (char *)"delete_C", _wrap_delete_C, METH_VARARGS, NULL},
{ (char *)"C_f", _wrap_C_f, METH_VARARGS, NULL},
{ (char *)"C_swigregister", C_swigregister, METH_VARARGS, NULL},
{ NULL, NULL, 0, NULL }
};

}
fail:
