问题
I'm currently running MS COCO MatlabAPI on WIN 10. I want to produce a file called gasonMex.mexw64. I have installed MinGW64 and simple Matlab .c file has been tested working.
I used
mex -v COMPFLAGS='$COMPFLAGS -std=c++11 -Wall' -largeArrayDims gasonMex.cpp
Verbose mode is on.
... Looking for compiler 'MinGW64 Compiler (C++)' ...
... Looking for environment variable 'MW_MINGW64_LOC' ...Yes ('C:\MATLAB\SupportPackages\R2016a\MW_MinGW_4_9').
... Looking for file 'C:\MATLAB\SupportPackages\R2016a\MW_MinGW_4_9\bin\g++.exe' ...Yes.
... Looking for folder 'C:\MATLAB\SupportPackages\R2016a\MW_MinGW_4_9' ...Yes.
Found installed compiler 'MinGW64 Compiler (C++)'.

So it seems that c++11 is included. But I still got the error of
