MEX compilation error of 64-bit mode

Hi,

I have Matlab 2017b and I have installed the latest minGW compiler. I manually set up the enviroment variable to point to this minGW folder. However, when I try to command compile a c file sfun_nInd.c

I got this:

>> mex sfun_nInd.c

Building with 'MinGW64 Compiler (C)'.

Error using mex

C:\Users\\models\sfun_nInd.c:1:0: sorry, unimplemented: 64-bit mode not

compiled in

/*

Any idea where to start to fix this?

Can you post the sfun_nind.c code? Is this message in the source code itself?

It's the same as sfun_atol.c in the demo folder. I just changed the first line of code to

#define S_FUNCTION_NAME sfun_nInd

and renamed the file name to sfun_nInd.c. This was a starter test and it failed. Thanks for the help.
