Unable to locate an entry point

When I was trying to loading a MAT file from a C application, the application always failed with the error mesage appearing in the attached 'error.jpg'. Would you tell me how to rectify this error?

For further information, my path information in 'path.txt' is attached.

Are you using the MATLAB C API to read MAT file?

Can you share the C code that causes the error?

Also, can you share the MAT file that you are trying to read?

The error says invisible chars so I'm suspecting that there could be some unrecognizable characters somewhere.
