Hi -

We used the ptr_container library under gcc and Linux. We are now porting our software to the Integrity OS and the Green Hills Multi C++ compiler. This compiler has the EDG front end. It cannot compile reversible_ptr_container.hpp.

I had to change this:

class reversible_ptr_container { private: BOOST_STATIC_CONSTANT( bool, allow_null = Config::allow_null );

typedef BOOST_DEDUCED_TYPENAME Config::value_type Ty_;

To this:

class reversible_ptr_container { public: typedef BOOST_DEDUCED_TYPENAME Config::value_type Ty_; private: BOOST_STATIC_CONSTANT( bool, allow_null = Config::allow_null );

The compiler complains that the typedef Ty_ is private, but it is used in the public part of the class where it should not be accessible.

Huh?

...

I believe, but am not completely sure, that technically the compiler is correct. We have noticed that this EDG front end is very picky (in a good way).

Private doesn't mean that the class's own functions can't use it.

In what context does the compiler complain?

Sorry I should have included the error. Compiling any code that uses any ptr_container produces the following message (well actually there are a few more): "C:\boost\boost_1_33_1\boost/ptr_container/detail/reversible_ptr_container.hpp", line 86: error #265-D: type "boost::ptr_container_detail::reversible_ptr_container::Ty_ [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator]" is inaccessible static Ty_* allocate_clone_from_iterator( Iter i ) ^ detected during: instantiation of class "boost::ptr_container_detail::reversible_ptr_container::null_clone_allocator [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator, allow_null_values=false]" at line 283 instantiation of "void boost::ptr_container_detail::reversible_ptr_container::null_policy_deallocate_clone(const boost::ptr_container_detail::reversible_ptr_container::Ty_ *) [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator]" at line 233 instantiation of "void boost::ptr_container_detail::reversible_ptr_container::remove(I) [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator, I=boost::void_ptr_iterator>::iterator, boost::ptr_container_detail::sequence_config>>::U>]" at line 240 instantiation of "void boost::ptr_container_detail::reversible_ptr_container::remove(I, I) [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator, I=boost::void_ptr_iterator>::iterator, boost::ptr_container_detail::sequence_config>>::U>]" at line 213 instantiation of "void boost::ptr_container_detail::reversible_ptr_container::remove_all() [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator]" at line 364 instantiation of "boost::ptr_container_detail::reversible_ptr_container::~reversible_ptr_container() [with Config=boost::ptr_container_detail::sequence_config>>, CloneAllocator=boost::heap_clone_allocator]" at line 162 of "C:\boost\boost_1_33_1\boost/ptr_container/ptr_sequence_a dapter.hpp" instantiation of "boost::ptr_sequence_adapter::ptr_sequence_adapter(const boost::ptr_sequence_adapter::allocator_type &) [with T=int, VoidPtrSeq=std::deque>, CloneAllocator=boost::heap_clone_allocator]" at line 45 of "C:\boost\boost_1_33_1\boost/ptr_container/ptr_deque.hpp" instantiation of "boost::ptr_deque::ptr_deque(const boost::ptr_deque::allocator_type &) [with T=int, CloneAllocator=boost::heap_clone_allocator, Allocator=std::allocator]" at line 42 of "Common\Ttnt\JtrsKeyTag.cpp" Regards, BN

To this:

class reversible_ptr_container { public: typedef BOOST_DEDUCED_TYPENAME Config::value_type Ty_; private: BOOST_STATIC_CONSTANT( bool, allow_null = Config::allow_null );

The problem is, I believe, that null_clone_allocater, as a nested class of reversible_ptr_container, has no special visibility to see the type Ty_, which is private in the outer class.

This makes sense. I guess a fix could be to make the class a friend, but I'm not keen on using this with templates. I guess I shuld simply use typedef typename Config::value_type* pointer; inside null_clone_allocator Thomas, can we fix this for 1.34? -Thorsten
