In the Boost.Assign documentation, the following example of list_of() is given:
const list<int> primes = list_of(2)(3)(5)(7)(11);
However, I have tended to write this instead:
const list<int> primes(list_of(2)(3)(5)(7)(11));
This is causing problems with the Microsoft Visual C++ 2010 Beta 1 compiler. Using Visual C++ 2008, both lines compile fine but with 2010 Beta 1, the second produces the following error:
error C2668: 'std::list<_Ty>::list' : ambiguous call to overloaded function with [_Ty=int] could be 'std::list<_Ty>::list(std::list<_Ty> &&)' with [_Ty=int] or 'std::list<_Ty>::list(unsigned int)' with [_Ty=int] while trying to match the argument list '(boost::assign_detail::generic_list<T>)' with [T=int]
Is this:
a) My fault? Should I be using copy initialization rather than direct initialization?
Well, if it works more portably, then why not.
b) A problem with the 2010 beta compiler?
I really don't know. Try to ask a question on some newsgroup with some C++ gurus.
or c) A problem with Boost.Assign?
Well, I think Boost.Assign does everything it can. -Thorsten
