mex compile error: Unrecognized switch: -cxx

编译 mex 文件 a 时会出现上述错误。我将MATLAB2013与 mex 编译器一起使用：Microsoft SDK 7.1 。我希望编译器打印的以下调试信息可能有用：

Use the -help option for more information, or consult the MATLAB API Guide. 

C:PROGRA~1MATLABR2013ABINMEX.PL: Error: Unrecognized switch: -cxx

以下是 -cxx MEX 命令行选项的帮助：

Command Line Options Available Only on UNIX Platforms:
    -cxx
        Use the C++ linker to link the mex-file if the first source file 
        is in C and there are one or more C++ source or object files. This 
        option overrides the assumption that the first source file in 
        the list determines which linker to use.

如您所见，它说 -cxx 仅在 UNIX 平台上可用。我认为您无需做任何特别的事情即可在Windows上编译C++MEX;只需像以前一样称呼 MEX，但没有 -CXX。
