I am trying to port parts of boost to the Microware/Radisys OS9 platform. This is really an old embedded systems C++ compiler that has not been updated since about 1997. Anyways I can get shared_ptr to work and convert between convertible types. But when I try to compile anything out of type_traits library the compiler can't handle anything like:

typedef typename se_t::template type<T> helper; (line 156 in is_enum.hpp)

My compiler error is "expected an identifier" at ::template. I am guessing that I am out of luck, but is there any way to rewrite or simplify these kind of constructs?

I suspect that not much in Boost will work with such an old compiler. However, you can try replacing template with BOOST_NESTED_TEMPLATE. In Christ, Steven Watanabe

I fear you may be out of luck there - I can't think of any way to simplify that off the top of my head :-( If is_enum is just being used as a dependency to some other trait, and you don't actually care about enum types, then you could try hard coding is_emun to just evaluate to false for all types and hope for the best...
