Invalid -MEX file mexw64.

Hello. I try to compile a mex file. I see error message like below.

"Invalid MEX File 'C:\...\myMEX.mexw64'".

Only this, no other message like " The specified module could not be found" or "myMEX.mexw64 is not a valid Win32 application" appears.

I can't find reason this issue happens.

My Matlab version is R2014a 64bit. And I run Matlab on Win 7 64bit. I use Visual Studio 2012.

Thank you.

Does the compile seem to work OK, and you just get errors when trying to run it?

Dear James Tursa.

Thank you for your comment.

I've compiled MEX file successfully. And get error when trying to run it.

[James Tursa]

Can you compile and run a very basic function? E.g.,

#include "mex.h"
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) {}

[Wangjin Jin]

Yes.

[James Tursa]

Then start building from that. Start moving code from myMex.c into this simple function and see if you can still compile and run.

[Wangjin Jin]

Thank you.

Hi I have use facial landmarks "find_face_landmarks", but during compile I got this massage: Invalid MEX-file '\Documents\MATLAB\find_face_landmarks-1.2-x64-vc14-release\interfaces\matlab\find_face_landmarks.mexw64': The specified module could not be found.
