I am trying to implement Matlab in a C ++ program. http://www.cl.cam.ac.uk/~sjeh3/wii/ The application uses gtk a wii mote lib and the Matlab Camera Calibration Toolbox ( http://www.vision.caltech.edu/bouguetj/calib_doc/ ) . It works great. I want to use the Matlab layout tools to create the graphics provided by the application. But I am having problems creating an application using the Matlab engine.
In main.cpp, I just added the code from the matlab engdemo.cpp example to the main function and included engine.h and mex.h. Even with examples like engdemo.cpp, this error always occurs:
mex: the link '"... mexa64"' failed.
Here are the console views:

I forgot to say that I wanted to use the Matlab engine, not my C ++ application in Matlab. perhaps it was not so clear. I do not think that the program will work as a mex file.
