Unfortunately you left the message text in Chinese, so we do not know exactly what the problem is. Please translate to English before posting.

The errors are in the lines 546, 547, 548, 584, and 586 of SharedMemory.cpp where you are using the variable mxArray_tag. The type of that variable seems to be defined in line 83 of the include file SharedMemory.hpp.

See the MSDN error description for the errors (press F1 when the error number is selected in the output window or search online). The error C2027[^] tells you that the type of the variable is not known. The other errors are sourced by this one.

You should show us the definition of that variable or check it yourself. The reason may be another missing include file.

[UPDATE]
I googled a little bit and found that the missing mxArray_tag structure is defined in matrix.h (for Matlab versions up to R2010A). See http://undocumentedmatlab.com/blog/matlabs-internal-memory-representation/[^].

So including matrix.h may solve the error.

The key message is

C++

SharedMemory.cpp(546) : error C2027: Using undifined datatype 'mxArray_tag'
        c:\program files\matlab\r2012a\bin\SharedMemory.hpp(83) : please check  the annoucenment of 'mxArray_tag'

So you need to include the header for this data object.

BTW: Warnings arent errors....
