MATLAB: Do I receive an error when running a standalone application compiled with MATLAB Compiler 4.10 (R2009a) on Linux

MATLAB Compilermccrun_magicsquarerun_magicsquare.sh

I have compiled my MATLAB file called 'mytest.m' into a standalone application on a Linux machine. I am trying to run the MATLAB generated script 'run_mytest.sh', which sets the environment variables and runs the standalone application, as follows:

 ./run_myapp_Linux32.sh  /home/username/MCR

However I get the following error:

 ------------------------------------------
 Setting up environment variables

 LD_LIBRARY_PATH is .:/home/username/MCR/runtime/glnx86:/home/username/MCR/bin/glnx86:/home/username/MCR/sys/os/glnx86:/home/username/MCR/sys/java/jre/glnx86/jre/lib/i386/native_threads:/home/username/MCR/sys/java/jre/glnx86/jre/lib/i386/server:/home/username/MCR/sys/java/jre/glnx86/jre/lib/i386/client:/home/username/MCR/sys/java/jre/glnx86/jre/lib/i386
 ./mytest: error while loading shared libraries: libmwmclmcrrt.so: cannot open shared object file: No such file or directory

The directory /home/username/MCR contains the MATLAB Compiler Runtime (MCR) Installation.

This enhancement has been incorporated in Release 2010a (R2010a). For previous product releases, read below for any possible workarounds:

The MATLAB Compiler generated run script, that is, 'run_mytest.sh' expects the path to the specific MATLAB Compiler Runtime (MCR) version. For example, use the following command to run the script:

 ./run_mytest.sh  /home/username/MCR/v710

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:

            setenv XAPPLRESDIR <mcr_root>/v78/X11/app-defaults
        Mac
            setenv DYLD_LIBRARY_PATH

MATLAB: What is the correct value for LD_LIBRARY_PATH on 64-bit Linux when using MATLAB Compiler 4.4 (R2006a)

There is an error in the documentation for MATLAB Compiler 4.4 (R2006a) with regards to the value of the LD_LIBRARY_PATH environment variable on 64-bit Linux platforms.

On a development machine, the documentation should read:

 setenv LD_LIBRARY_PATH 
         $MATLABROOT/sys/os/glnxa64: 
         $MATLABROOT/bin/glnxa64: 
         $MATLABROOT/extern/lib/glnxa64: 
         $MATLABROOT/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/native_threads: 
         $MATLABROOT/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/server: 
         $MATLABROOT/sys/java/jre/glnxa64/jre1.5.0/lib/amd64 
     setenv XAPPLRESDIR $MATLABROOT/X11/app-defaults

For a deployment machine, the documentation should read:

 setenv LD_LIBRARY_PATH 
$MCR_ROOT/$VER/runtime/glnxa64: 
$MCR_ROOT/$VER/sys/os/glnxa64: 
$MCR_ROOT/$VER/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/native_threads: 
$MCR_ROOT/$VER/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/server: 
$MCR_ROOT/$VER/sys/java/jre/glnxa64/jre1.5.0/lib/amd64:
 setenv XAPPLRESDIR $MCR_ROOT/$VER/X11/app-defaults

In the preceding example, $MATLABROOT and $MCR_ROOT represent the root directories of the MATLAB ($MATLABROOT) and MATLAB Compiler Runtime (MCR) installation ($MCR_ROOT) respectively. $VER refers to the version of MCR installed (for example, v73 or v74).
