I got these error compiling NT2 with proto trunk
/usr/local/include/boost-latest/boost/proto/detail/decltype.hpp:67:56:
error: 'M0' has not been declared
/usr/local/include/boost-latest/boost/proto/detail/decltype.hpp:67:1:
error: expected identifier before '~' token
/usr/local/include/boost-latest/boost/proto/detail/decltype.hpp:67:1:
error: expected ')' before '~' token
/usr/local/include/boost-latest/boost/proto/detail/decltype.hpp:67:1:
error: ISO C++ forbids declaration of
'BOOST_PP_REPEAT_1_BOOST_PROTO_MAX_ARITY' with no type
/usr/local/include/boost-latest/boost/proto/detail/decltype.hpp:67:1:
error: expected ';' before '~' token
Our code is :
#include <boost/config.hpp>
#include <boost/detail/workaround.hpp>
#if BOOST_WORKAROUND(BOOST_MSVC, >= 1600) && defined BOOST_NO_DECLTYPE
#undef BOOST_NO_DECLTYPE
#endif
#include <boost/proto/detail/decltype.hpp>
#define NT2_DECLTYPE(EXPR, TYPE) BOOST_PROTO_DECLTYPE_(EXPR, TYPE)
Is detail/decltype.hpp a no-go to reuse this way ?
As for why we do this, we have to fight against some MSVC bug w/r to
decltype that PROTO_DECLTYPE seemed to fix.
