Hi, Michel.
`#define BOOST_RESULT_OF_USE_DECLTYPE` is necessary to compile the above code. Without this, we have compiler errors (the oven library seems not fully compatible with new compilers yet).
I am Oven Library mantainer(now manager).
Good to know :)
C++0x lambda hasn't result_type typedef
Ah, this is the reason for the compiler error. Thanks for correcting me. (Cc'ing to Daniel) So, when using boost::result_of with C++0x lambda functions, we have to define BOOST_RESULT_OF_USE_DECLTYPE. This is a bit bothersome, and so I expect that, in the future, BOOST_RESULT_OF_USE_DECLTYPE gets automatically defined in compilers with N3276 support. Something like // boost/utility/result_of.hpp #ifndef #BOOST_NO_DECLTYPE_N3276 #define BOOST_RESULT_OF_USE_DECLTYPE #endif ? (BOOST_NO_DECLTYPE_N3276 is not yet included in Boost.Config.)
