[unordered] 1.48 beta1 fails to compile with MSVC 2010 SP 1, error C2027: use of undefined type 'boost::type'
After trying out beta 1, I am seeing some failures with unordered containers, see attached file. Microsoft (R) C/C++ Optimizing Compiler Version 16.00.40219.01 for x64 The code compiles without problems under 1.47.0. Unfortunately, I cannot yet publish the source code that triggers this problem. Any hints where to start investigating this? -- /Johan.

Can you try something? Look in boost/unordered/detail/allocator_helpers.hpp for the line: #if !defined(BOOST_NO_SFINAE_EXPR) || BOOST_WORKAROUND(BOOST_MSVC, >= 1500) and change it to: #if !defined(BOOST_NO_SFINAE_EXPR) Unordered uses a bit of a hack on Visual C++ to implement some of the C++11 functionality. That change disables it and uses the less capable fallback implementation (which is actually a lot better now than it originally was, so using a hack seems less appealing).

Thankyou - yes, that solved the problem. The code now compiles as before. -- /Johan.

It would be great if this fix could be rolled into 1.48. Thanks, -- /Johan.

It should be, I'm waiting for the tests to run on the trunk testers. There are a couple of other changes to be merged and only one windows tester has run since the last change.
