MATLAB: Doesn’t MCR add path with libmat.dll to PATH environment variable

libmat.dlllibmx.dllMATLAB Compilermcrpath environment

The MATLAB Compiler Runtime installer can be download here: http://www.mathworks.com/products/compiler/mcr/

The installer will add the following path to PATH environment variable where there is the DLL file mclmcrrt:

C:\Program Files (x86)\MATLAB\MATLAB Compiler Runtime\v81\runtime\win32

My question is why the installer don't add this path to PATH environment variable?:

C:\Program Files (x86)\MATLAB\MATLAB Compiler Runtime\v81\bin\win32

Under this path, there are libmat.dll and libmx.dll. These files are important DLL files, because C/C++ programs can dynamically link to them to access MAT files. It could be a good idea that MAT C/C++ programs can be easily deployed to some computers by simply installing the MCR if the MCR installer add the path with libmat.dll and libmx.dll to PATH environment variable. Isn't it?

It is because the Runtime Libraries (MCR) not only works for C/C++ projects, but also for standalone executable files generated using the MATLAB Compiler. The the standalones case, it should not need extra PATH variables. For anything extra (C/C++, Java, .NET ), you can add the required components for your project.

MATLAB: Is there a checklist to successfully deploy an application/ library on a system using MATLAB Compiler Runtime

MATLAB Deployment Checklist

===========================

Use this checklist to successfully deploy your application, component,

or library.

You can distribute a MATLAB Compiler-generated standalone application,

component, or library to any target machine with the same operating

system as the machine on which the application was compiled

(the "source" development machine).

For more information, see the documentation for the MATLAB Compiler at:

http://www.mathworks.com/access/helpdesk/help/toolbox/compiler/

1. Ensure that the MATLAB Compiler Runtime (MCR) is installed on target

   machines, and ensure you have installed the correct version. To verify 
   this, do the following: 
    A. Attempt to verify the MCR exists on your system.
    The MCR usually resides in these locations on these platforms:
    Operating System        Path to MCR
    ================        ===========
    Windows              C:\Program Files\MATLAB\MATLAB Compiler Runtime\v78
    Mac                  Applications/MATLAB/MATLAB_Compiler_Runtime/v78 
    Linux/Solaris        *** No predetermined installation location ***
                         Contact your system administrator.  
        NOTE: For information about the installation process and the MCR, 
              type "help MCR" or "help mcrinstaller" at the MATLAB 
              command prompt.

2. Add the MCR directory to the path specified by the target system's

   environment variable. 
    A. Locate the name of the environment variable to set, using the table 
       below:
    Operating System        Environment Variable
    ================        ====================
    Windows                PATH
    Linux                  LD_LIBRARY_PATH
    Solaris                LD_LIBRARY_PATH
    Mac                    DYLD_LIBRARY_PATH
    B. Set the path by doing one of the following:
        On Windows systems:
        * Add the MCR directory to the environment variable by opening a 
        command prompt and issuing the DOS command, specifying either 
        win32 or win64:
            set PATH=C:\Program Files\MATLAB\MATLAB Compiler Runtime\v78\runtime\{win32|win64};%PATH% 
        Alternately, for Windows, add the following pathname:
            C:\Program Files\MATLAB\MATLAB Compiler Runtime\v78\runtime\{win32|win64}
        to the PATH environment variable, specifying either win32 or win64, 
        by doing the following:
            1. Select the My Computer icon on your desktop.
            2. Right-click the icon and select Properties from the menu.
            3. Select the Advanced tab.
            4. Click Environment Variables.  
        On UNIX systems:
        * Add the MCR directory to the environment variable by issuing 
            the following commands:
        Linux
            setenv LD_LIBRARY_PATH
                <mcr_root>/v78/runtime/glnx86:

MATLAB: How to silently uninstall the MATLAB Compiler Runtime 7.16 (R2011b)

It is possible to uninstall the MATLAB Compiler Runtime (MCR) silently by following the steps mentioned below:

1) Navigate to the 'uninstall' folder at the installation location of the MCR. For example, the path to this folder for 32-bit MCR 7.16 is:

C:\Program Files (x86)\MATLAB\MATLAB Compiler Runtime\v716\uninstall

2) Open the 'uninstaller_input.txt' text file and initialize the 'mode' variable to 'silent' and uncomment the line by removing the '#' symbol in front of it.

3) Open Windows DOS prompt and navigate to the 'uninstall.exe' file. This file is persent in the 'bin\win32' (for 32-bit MCR) or 'bin\win64' (for 64-bit MCR) folder in the 'uninstall' folder mentioned in step 1 above. For example, the path to this folder for 32-bit MCR 7.16 is:

C:\Program Files (x86)\MATLAB\MATLAB Compiler Runtime\v716\uninstall\bin\win32

Note: This path will be different depending on the bitness of the MCR and the version of the MCR.

4) Execute the 'uninstall.exe' application present in thsi folder with the 'inputFile' flag by executing the following command on the Windows DOS prompt:

uninstall -inputFile "C:\Program Files (x86)\MATLAB\MATLAB Compiler Runtime\v716\uninstall\uninstaller_input.txt"
