使用SharedMenory时的编译器错误。 CPP

当我运行如下文件来设置sharedmemory时，有很多编译器错误，如何解决？谢谢！Windows version: Win7 64bitsMatlab version: R2012acomputer: 4 coresCompiler: Microsoft Visual C++ 2008 SP1When I run the file as below to set up sharedmemory, there are many compiler error, how to solve it? thanks!SharedMemory.cppc:\program files\matlab\r2012a\bin\SharedMemStack.hpp(357) : warning C4267: '=' : if 'size_t' is transformed to 'int'，, data may be missedSharedMemory.cpp(125) : warning C4996: 'strcmpi': The POSIX name for this item is deprecated.

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.关键信息是The key message isSharedMemory.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' 因此，您需要包含此数据对象的标头。 BTW：警告不是错误....So you need to include the header for this data object.BTW: Warnings arent errors.... 这篇关于使用SharedMenory时的编译器错误。 CPP的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
