Hi, The compiler (g++ 3.4.2) gives me an error when i write: B b;
vector<A>elemA(2, b); B can be, for instance, a pointer to an integer, or a class. A is defined as: class A{ public: A(B b) {} private: A(const A&){} //!< disallow copying A& operator=(const A&){ return const_cast<A&>(*this);} //!< disallow copying }; The strange thing is that the constructor i am invoking is the public one not the private. The compilation is fine when B is an integer. The message of the compiler is: g++ -g -Wall -c main.cc -o main.o main.cc: In function `void std::_Construct(_T1*, const _T2&) [with _T1 = A, _T2 = A]': /usr/lib/gcc/x86_64-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/stl_uninitialized.h:194: instantiated from `_ForwardIterator std::__uninitialized_fill_n_aux(_ForwardIterator, _Size, const _Tp&, __false_type) [with _ForwardIterator = A*, _Size = long unsigned int, _Tp = A]' /usr/lib/gcc/x86_64-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/stl_uninitialized.h:219: instantiated from `_ForwardIterator std::uninitialized_fill_n(_ForwardIterator, _Size, const _Tp&) [with _ForwardIterator = A*, _Size = long unsigned int, _Tp = A]' /usr/lib/gcc/x86_64-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/stl_vector.h:194: instantiated from `std::vector<_Tp, _Alloc>::vector(size_t, const _Tp&, const typename std::_Vector_base<_Tp, _Alloc>::allocator_type&) [with _Tp = A, _Alloc = std::allocator<A>]' main.cc:33: instantiated from here main.cc:21: error: `A::A(const A&)' is private /usr/lib/gcc/x86_64-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/stl_construct.h:81: error: within this context make: *** [main.o] Error 1 Thanks in advance.
