Re: [Boost-users] Declaring an iterators for std::list contain weak ptrs

Hello all,

I am pretty sure I am not getting something conceptually here, but can anyone shed some light please.

I am writing a template class which contains a std::list of weak_ptr<t1>

template<typename T1> class fred { private : typedef boost::weak_ptr<T1> MyPtr; typdef std::list<MyPtr> MyPtrList;

MyPtrList MyList;

public :

Return type missing here. void?

DoSomething() {

"typename" missing here.

MyPtrList::iterator pos;

for (pos = MyList.begin(); pos < MyList.end(); ++pos) { ...do stuff.. } } }

Now that looks fine to me, but the line where I declare the iterator fails with a

error: Expect ';' before 'pos'

and I don't know why - it seems fine to me.

Using boost 1.33.1 recent cross compiler to ARM.
