I have this error on _MSC_VER 1400 (MSVC8?) so I was thinking to use:
#if BOOST_WORKAROUND(BOOST_MSVC,>= 1400) ... // Workaround wrapper for BOOST_CONCEPT_CHECK following your code below. #else ... // Original BOOST_CONCEPT_CHECK with no workaround. #endif
That is the general idea but I'd go with #elif BOOST_WORKAROUND(BOOST_MSVC, <= 1600) && BOOST_WORKAROUND(BOOST_MSVC, >= 1400) since I'm still hopeful that in the upcoming MSVC release the workaround won't be necessary.
template<typename T1, typename T2> struct requires_msvc10 { typedef typename T2::type type; };
template<typename T> struct relay_type_msvc10 { typedef T type; };
#define BOOST_CONCEPT_STRIP_PARENS(x) x #define BOOST_CONCEPT_TEST_SINGLE_REQUIREMENT(x) \ decltype(::boost::_requires_<void(*) (x)>::value)
I don't have `decltype()` (I think that is a C++0x feature...). What shall I use instead? Boost.TypeOf somehow? Can you please sketch the code without `decltype()`?
Actually the decltype isn't required at all. It is just a remnant of a previous attempt where without accessing ::boost::_requires_<>::value the compiler didn't seem to instantiate the _requires_ template. I should have double checked. I do not have Visual Studio 2005 (MSVC8) installed right now but on Visual Studio 2008 (MSVC9) it compiles when simply leaving out the decltype and ::value. Here is a link to a patchfile: https://svn.boost.org/trac/boost/attachment/ticket/4526/pathfile2.patch Have a nice day, Stefan
