MATLAB: Do I receive “mclcommain.dll not found” errors when I try to distribute the COM component created with the MATLAB COM Builder 1.0 (R13)

MATLAB Builder for COMmclcommainmclcommain.dllmglinstaller

I receive "mclcommain.dll not found" errors when I try to distribute my COM component created with the MATLAB COM Builder.

Best Answer

Either of the following two things may cause this error:

1) The package utility is not used to create a self-extracting and self-registering distributable component. For more information on this, refer to the Packaging section of COM Builder Users Guide.

Use the package utility to package and distribute the component.

2) MATLAB Com Builder is using a demo license of MATLAB Compiler, in which case MGLINSTALLER is not included with MATLAB Compiler. MGLINSTALLER is needed to install the run time libraries for the core MATLAB components.

Please note that you cannot distribute COM Builder components created using a Demo license of MATLAB Compiler. You must use the full version of MATLAB Compiler to distribute your component.

MATLAB: Do I receive a “Could not find the compiler ‘‘ on the DOS path.” error when building COM objects in MATLAB 7.0.1 (R14SP1)

This happens because Microsoft Visual Studio Compiler (MSVC) 9.0 is not a supported compiler for the MATLAB Builder for COM 1.1.2 (R14SP1).

A list of supported compilers for MATLAB 7.0.1 (R14SP1) may be found at the following URL:

 <http://www.mathworks.com/support/compilers/1601_70.html>

As a workaround, use either the MSVC 6.0 Professional Edition with MATLAB 7.0.1 (R14SP1) or uprgrade to MATLAB 7.7 (R2008a) to be able to use the MSVC 9.0 compiler.

MATLAB: Am I unable to distribute the stand-alone application built with the demo version of the MATLAB Compiler 3.0 (R13)

A demo version of the MATLAB Compiler 3.0 (R13) limits users such that they are not allowed to distribute their compiled stand-alone application. The full version of the MATLAB Compiler is necessary in order to distribute your compiled application to others.

There are two ways in which the demo version of the MATLAB Compiler differs from the full version:

First, the MGLINSTALLER, which normally resides in the following directory, does not exist in the Demo version of the MATLAB Compiler and Libraries:

$MATLAB/extern/lib/win32      (where $MATLAB is the root MATLAB directory)

The MGLINSTALLER is needed to distribute stand-alone applications to users who do not own MATLAB. This is not necessary in the demo version of the MATLAB Compiler because applications created with the demo version cannot be distributed.

Second, stand-alone applications created with the demo version of the MATLAB Compiler require a license file before they will run. This license file should be located in your $MATLAB\bin\win32 directory. That directory must be on the system path before any other installation of MATLAB.

If you install the stand-alone application on a system that does not have MATLAB, you will receive an error such as:

 Could not check out a license for CPP_Math_Library

 License Checkout Failed...

With the full version of the MATLAB Compiler, the generated executable does not check for any licenses. This is only used to prevent distribution of applications created using the demo version of the MATLAB Compiler.
