[boost] [shared_array] Conflict with Boost.TR1

From: John Maddock (john_at_[hidden])
Date: 2006-07-10 06:06:46

Not sure what we can do about this but:

#include <boost/shared_array.hpp>

doesn't compile when Boost.TR1 is added to the include path.  We've been 
through this before with shared_ptr.hpp and a solution was found, any chance 
of some magic here as well?  The alternative is for all the 
shared_ptr/shared_array code to include <boost/config/no_tr1/memory.hpp> 
rather than <memory> directly.  In fact the latter option is probably easier 
to maintain in the long run: the problem is sporadic, hard to reproduce 
(because it depends upon which headers are included and in which order), and 
even harder to track down :-(

Sorry, but there ain't no easy way....

Thanks,

John
