Boost using MS Visual Studio 2010 - C2027
Hi! I've tried to build Boost using MS Visual Studio 2010, but I'm getting a C2027 error. Basically the problem is known and located as a problem of the MS compiler: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?Feedba... Is there still a workaround? Greets! Christofer Here comes the error....: 1>c:\projekte\boost\1.40.0\boost\bind\bind.hpp(1657): warning C4180: qualifier applied to function type has no meaning; ignored 1> c:\projekte\boost\1.40.0\boost\bind\bind.hpp(1691) : see reference to class template instantiation 'boost::_bi::add_cref<Pm,I>' being compiled 1> with 1> [ 1> Pm=FileTime<UTC> (__thiscall File::* )(void), 1> I=1 1> ] 1> c:\projekte\ps3controlmodule\productformattingasd\fileadmin.cpp(346) : see reference to class template instantiation 'boost::_bi::dm_result<Pm,A1>' being compiled 1> with 1> [ 1> Pm=FileTime<UTC> (__thiscall File::* )(void), 1> A1=boost::arg<1> 1> ] 1>c:\projekte\boost\1.40.0\boost\bind\bind.hpp(1691): error C2027: use of undefined type 'boost::_bi::add_cref<Pm,I>' 1> with 1> [ 1> Pm=FileTime<UTC> (File::* )(void), 1> I=1 1> ] 1> c:\projekte\ps3controlmodule\productformattingasd\fileadmin.cpp(347) : see reference to class template instantiation 'boost::_bi::dm_result<Pm,A1>' being compiled 1> with 1> [ 1> Pm=FileTime<UTC> (__thiscall File::* )(void), 1> A1=boost::arg<2> 1> ] 1> 1>Build FAILED.

This is not the same issue. The code in the bug report is incorrect (it passes one argument to &CTest::is_A instead of two). Your code seems correct. You might consider submitting a separate bug report against MSVC 2010.
Is there still a workaround?
One option is to use MSVC2010's own std::bind; another is to wrap the member function in mem_fn.
hi! ok.. - "wrap the member function in mem_fn. " can you give me some dummy code how to do that, or another hint... wrapping in case of packing it into another namespace or {..} ? 2009/11/3 Peter Dimov <pdimov@pdimov.com>

You now have boost::bind( &File::get_file_time, _2 ), right? Change it to boost::bind( boost::mem_fn( &File::get_file_time ), _2 ) and see if it helps. I hope it does. :-)
Hi Peter, it help for some of the errors, but one is still there: bind.hpp(1691): error C2027: use of undefined type 'boost::_bi::add_cref<Pm,I>' ------------------

ok, sorry! just putting some more "boost::mem_fn(" in the code already helps... - sorry for the question! 2009/11/4 Christofer Weßeling <c.wesseling@googlemail.com>

Are you sure using Beta 2 (only released a few days ago)?
