Hi,
The correct usage of declspec export/import has fixed several problems. We
have now been able to narrow another runtime problem we see.
We have a base class, ACE_Reactor_Impl, from that we have derived
ACE_Select_Reactor_Impl (all in the ACE library). In our code we do:
this->select_reactor_ =
dynamic_cast<ACE_Select_Reactor_Impl *> (r);
if (select_reactor_ == 0)
{
errno = EINVAL;
return -1;
}
We now see that this->select_reactor_ is 0, so the dynamic cast fails.
When we print the typename or *r we get:
20ACE_Select_Reactor_TI19ACE_Reactor_Token_TI9ACE_TokenEE20ACE_Select_Reacto
r_TI19ACE_Reactor_Token_TI9ACE_TokenEE
ACE_Select_Reactor_T is a template derived from ACE_Select_Reactor_Impl. So,
we should be able to do a dynamic cast to AE_Select_Reactor_Impl. Could this
be a problem with rtti or again symbol exports?
Anyone an idea?
Danny, the cast is in Select_Reactor_Base.cpp, line 614. Reproducable by
running tests/Reactor_Exception_Test
