How do I use LOADLIBRARY in a deployed program generated from MATLAB Compiler?

I want to deploy a MATLAB program that uses LOADLIBRARY function, but LOADLIBRARY requires a compiler.

Is there anyway to I can deploy a program onto a computer that does not require install a compiler?

The compiler is not needed on deployed machine.

One can generate prototype files, and pack them using -a option together with MCC.

Here is an example:

At command line :

loadlibrary('shrlibsample','shrlibsample.h','mfilename','mylibraryfile');

This would generates all the prototype files , including a m file called "mylibraryfile.m", which provides LOADLIBRARY entry point.

This command would only need to be performed once.

In deployed program, you may use LOADLIBRARY in this way:

loadlibrary('shrlibsample', @mylibraryfile);

libfunctions('shrlibsample','-full');

The next step is to use MATLAB compiler to compile the program, you would need to include the prototype files in the project.

For example in a 64 bit MATLAB, you would need to include:

1.mylibraryfile.m

2.shrlibsample.dll

3.shrlibsample_thunk_pcwin64.dll

mcc -v -m out.m -a 'mylibraryfile.m' -a 'shrlibsample.dll' -a 'shrlibsample_thunk_pcwin64.dll'

out.m is the MATLAB program that uses LOADLIBRARY to load the file "mylibraryFile".
