Error while loading library

Hi

After using loadinglibaray command.

% loadlibary(dll name, header file name) : Load a DLL into memory so that MATLAB can call it.
loadlibrary('Madlib', 'Madlib');

I got following error

Error loading library intermediate output follows.
The actual error is at the end of this output.

The code worked well in the order matlab version 2018, I am not sure if it's due to the newest version of matlab or maybe I need to set up extra things?

The file (Madlib) being loaded in this case should be corrct since they were used to work in the order version, any help would be appreciated

typedef unsigned char bool;

That would be a problem if bool was already defined as a datatype.

You should check your Madlib.h and consider removing that typedef .
