[asio] STLPort and std::vector<const Pod_Type>
Hi, STLPort doesnt seem to allow const-types as parameters to std::vector. It chokes in the std::allocator which define const_reference as const reference, making the two the same type. This creates multiple declarations for function-members: pointer address(reference __x) const { return &__x; } const_pointer address(const_reference __x) const { return &__x; } Is the STLPort right in this context or should something be done? This is making this code fails: std::vector<char> v(128); boost::asio::buffer(v); The problem is that even with non-const pod type boost::asio::buffer is instatiating std::vector<const char>. Thanks, -- Felipe Magno de Almeida
Forgot to mention that I'm using VC7.1, boost CVS, asio 0.3.6 and STLPort 4.6.2 -- Felipe Magno de Almeida

STLport 4.6.2 is pretty old, has not the best VC7.1 support and is considered a bad release (i.e. you should prefer 4.5.3 over 4.6, though that one doesn't have ). If you want to use STLport, please use the current 5.0 release. Uli

I believe that STLPort is correct. std::allocator<int const> isn't valid, and neither is std::vector<int const, A> because a const type is not Assignable.

Thanks for letting me know. I have just now removed the spurious overload from the CVS version. Cheers, Chris
