c++ - mex编译错误:无法识别的开关:-cxx

编译mex文件时，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：

vl_compilenn: * Compiler and linker configurations *
vl_compilenn:   intermediate build products directory:
C:\Dima  \Projects_C   \Libraries\matconvnet\matlab\mex\.build
vl_compilenn:   MEX files: C:\Dima\Projects_C\Libraries\matconvnet\matlab
\mex/
vl_compilenn:   MEX compiler options: -DNDEBUG -D__SSSE3__ -cxx
vl_compilenn:   MEX linker options: -lmwblas -lgdiplus
vl_compilenn: * Reading images *
vl_compilenn:   vl_imreadjpeg enabled
vl_compilenn:   image library: gdiplus
vl_compilenn:   image library compile flags:
vl_compilenn:   image library link flags: -lgdiplus
vl_compilenn: MEX: -outdir C:\Dima\Projects_C\Libraries\matconvnet\matlab
\mex\.build matlab\src\vl_imreadjpeg.cpp -c -DNDEBUG -D__SSSE3__ -cxx
Usage:
    MEX [option1 ... optionN] sourcefile1 [... sourcefileN]
        [objectfile1 ... objectfileN] [libraryfile1 ... libraryfileN]

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


C:\PROGRA~1\MATLAB\R2013A\BIN\MEX.PL: Error: Unrecognized switch: -cxx

最佳答案

这是-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。我认为您不需要做任何特殊的事情就可以在Windows上编译C ++ MEX。只需按原样调用mex，但不使用-cxx。
