Why do I receive an error when compiling a MATLAB graphics application?

I am having a problem compiling a stand-alone program that I wrote in MATLAB. The Engine of this file is a MATLAB function that calls a bunch of other files. I used the following MATLAB compiling command to create a stand-alone executable:

mcc -t -B  sgl filenames.m

I believe I have the C Math Library, C Graphics Library, and other MATLAB libraries installed. However, I keep receiving the following error message:

ERROR: undefined reference to '_mclMainhg'

This error occurs when the MATLAB C/C++ Graphics library is not properly installed.

You can verify if this is indeed the case by looking into the

$MATLAB/extern/examples folder

(where $MATLAB = the MATLAB root directory on your machine)

to see if a folder called "sgl" exists. If it does not exist, you do not have the MATLAB C/C++ Graphics Library and therefore will not be able to compile any MATLAB application that uses graphics.

You may purchase and install the MATLAB C/C++ Graphics Library product if you are using MATLAB 6.1 (R12.1) and earlier.

In MATLAB 6.5 (R13), the MATLAB Compiler tool is sold as an integrated product that includes the MATLAB C/C++ Graphics Library and the MATLAB C/C++ Math Library. Therefore, if you do not see the "sgl" folder in MATLAB 6.5 (R13), you will need to purchase and install the complete MATLAB Compiler product.
