The MIPSpro problems are due to a hickup in is_base_and_derived.hpp.
Here is the relevant *preprocessed* piece of code:
template <typename B, typename D>
struct bd_helper
{
template <typename T>
static type_traits::yes_type check(D const volatile *, T);
static type_traits::no_type check(B const volatile *, int);
};
template<typename B, typename D>
struct is_base_and_derived_impl2
{
struct Host
{
operator B const volatile *() const;
operator D const volatile *();
};
static const bool value = sizeof(bd_helper<B,D>:: check(Host(), 0)) ==
sizeof(type_traits::yes_type);
};
And here is the error:
cc-1108 CC: ERROR File =
/u1/rwgrosse/rc_1_30_0/boost/boost/type_traits/is_base_and_derived.hpp, Line =
106
The indicated expression must have pointer-to-function type.
static const bool value = sizeof(bd_helper<B,D> ::check(Host(), 0)) ==
sizeof(type_traits::yes_type);
^
Findings:
- Replacing "sizeof(bd_helper<B,D> ::check(Host(), 0))" by "sizeof(int)"
leads to successful compilation.
- Removing the space before ::check doesn't make a difference.
MIPSpro is based on EDG 238. Are there known issues with "operator T"?
Ideas for a workaround are highly appreciated.
Thanks,
Ralf
