Boost using MS Visual Studio 2010 - C2027

[Christofer Weßeling]

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?FeedbackID=321192

Is there still a workaround?

Greets!

Christofer


Here comes the error....:

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.

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 {..} ?

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. :-)

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

ok, sorry! just putting some more "boost::mem_fn(" in the code already
helps... - sorry for the question!
