Anders,
thanks for testing :-)
AFAIK partial member spezialization on the return value of a method is
not supported with g++ 2.95.
Example (from synopsis-0.7/Cxx-API/include/Synopsis/Python/Object.hh)
// ...
class Object
{
// ...
public:
// ...
//. try to downcast to T, throw on failure
template <typename T>
static T narrow(Object) throw(TypeError);
// ...
};
template <typename T>
inline T Object::narrow(Object o) throw(Object::TypeError)
{
T retn(o.my_impl);
Py_INCREF(o.my_impl);
return retn;
}
// ...
template <typename T>
inline char Object::narrow(Object o) throw(Object::TypeError)
{
if (!PyString_Check(o.my_impl) || PyString_GET_SIZE(o.my_impl) != 1)
throw TypeError("object not a character");
char *value;
int length;
PyString_AsStringAndSize(o.my_impl, &value, &length);
return value[0];
}
// ...
So, I think the best is to make the port use gcc 3.3 on FreeBSD 4.x. Of
course it has to be checked whether synopsis compiled with gcc 3 works
with boehm-gc and python compiled with the system compiler (2.95.4).
I have uploaded an updated version of the port:
