MATLAB® Compiler™

C Standalone Application Target

Compiling the Application

This example takes an M-file, magicsquare.m, and creates a standalone C application, magicsquare.

1. Copy the file magicsquare.m from

   matlabroot/extern/examples/compiler
   

   to your work directory.

2. To compile the M-code, use

   mcc -mv magicsquare.m
   

   The -m option tells MATLAB Compiler (mcc) to generate a C standalone application. The -v option (verbose) displays the compilation steps throughout the process and helps identify other useful information such as which third-party compiler is used and what environment variables are referenced.

   This command creates the standalone application called magicsquare and additional files. The Windows platform appends the .exe extension to the name. See the table in Standalone Executable for the complete list of files created.

Testing the Application

These steps test your standalone application on your development machine.

Note   Testing your application on your development machine is an important step to help ensure that your application is compilable. To verify that your application compiled properly, you must test all functionality that is available with the application. If you receive an error message similar to Undefined function or Attempt to execute script script_name as a function, it is likely that the application will not run properly on deployment machines. Most likely, your CTF archive is missing some necessary functions. Use -a to add the missing functions to the archive and recompile your code.

1. Update your path as follows:

   Windows.  Add the following directory to your path.

   matlabroot\bin\win32

   UNIX.  Add the following platform-specific directories to your dynamic library path.

   Note   For readability, the following commands appear on separate lines, but you must enter each setenv command on one line.

   Linux

   setenv LD_LIBRARY_PATH 
   	matlabroot/sys/os/glnx86: 
   	matlabroot/bin/glnx86: 
   	matlabroot/sys/java/jre/glnx86/jre/lib/i386/native_threads: 
   	matlabroot/sys/java/jre/glnx86/jre/lib/i386/server: 
   	matlabroot/sys/java/jre/glnx86/jre/lib/i386:
   setenv XAPPLRESDIR matlabroot/X11/app-defaults
   

   Solaris 64

   setenv LD_LIBRARY_PATH 
   /usr/lib/lwp: 
   matlabroot/sys/os/sol64: 
   matlabroot/bin/sol64: 
   matlabroot/sys/java/jre/sol64/jre1.5.0/lib/sparcv9/native_threads: 
   matlabroot/sys/java/jre/sol64/jre1.5.0/lib/sparcv9/server: 
   matlabroot/sys/java/jre/sol64/jre1.5.0/lib/sparcv9: 
   setenv XAPPLRESDIR matlabroot/X11/app-defaults 
   

   Linux x86-64

   setenv LD_LIBRARY_PATH 
   	matlabroot/sys/os/glnxa64: 
   	matlabroot/bin/glnxa64: 
   	matlabroot/extern/lib/glnxa64:
   	matlabroot/sys/java/jre/glnxa64/jre/lib/amd64/native_threads: 
   	matlabroot/sys/java/jre/glnxa64/jre/lib/amd64/server: 
   	matlabroot/sys/java/jre/glnxa64/jre/lib/amd64:
   setenv XAPPLRESDIR matlabroot/X11/app-defaults
   

   Mac OS X

   setenv DYLD_LIBRARY_PATH 
   	matlabroot/bin/mac: 
   	matlabroot/sys/os/mac: 
   	/System/Library/Frameworks/JavaVM.framework/JavaVM: 
   	/System/Library/Frameworks/JavaVM.framework/Libraries
   setenv XAPPLRESDIR matlabroot/X11/app-defaults
   

   Intel Mac (Maci)

   setenv DYLD_LIBRARY_PATH 
     matlabroot/bin/maci: 
     matlabroot/sys/os/maci: 
     /System/Library/Frameworks/JavaVM.framework/JavaVM: 
     /System/Library/Frameworks/JavaVM.framework/Libraries 
   setenv XAPPLRESDIR matlabroot/X11/app-defaults 
   

   Note   If you are running a version of Intel Mac later than 10.3, use the bsh, rather than the csh, shell.

2. Run the standalone application from the system prompt (shell prompt on UNIX or DOS prompt on Windows) by typing the application name.

   magicsquare.exe 4              (On Windows)
   magicsquare 4                  (On UNIX)
   

   The results are:

   ans =
       16     2     3    13
        5    11    10     8
        9     7     6    12
        4    14    15     1

Deploying the Application

You can distribute a MATLAB Compiler generated standalone application to any target machine that has the same operating system as the machine on which the application was compiled.

For example, if you want to deploy an application to a Windows machine, you must use MATLAB Compiler to build the application on a Windows machine. If you want to deploy the same application to a UNIX machine, you must use MATLAB Compiler on the same UNIX platform and completely rebuild the application. To deploy an application to multiple platforms requires MATLAB and MATLAB Compiler licenses on all the desired platforms.

Note   MCRInstaller.exe has obsoleted the need for the function buildmcr or the creation of MCRInstaller.zip. See Replacement of MCRInstaller.zip and BUILDMCR Functionality for more details including complete file paths to all install programs.

Windows

Gather and package the following files and distribute them to the deployment machine.

UNIX

Distribute and package your standalone application on UNIX by packaging the following files and distributing them to the deployment machine.

Running the Application

These steps describe the process that end users must follow to install and run the application on their machines.

Preparing Your Machines

1. Install the MCR by running the MCRInstaller in a directory. For example, run MCRInstaller.exe in C:\MCR. For more information on running the MCR Installer utility, seeWorking with the MCR and Replacement of MCRInstaller.zip and BUILDMCR Functionality.

2. Add the following directory to your system path:

Note   For readability, the following commands appear on separate lines, but you must enter each setenv command on one line. On Windows XP, this directory is automatically added to your path.

Windows

<mcr_root>\<ver>\runtime\win32

Linux

setenv LD_LIBRARY_PATH 
	<mcr_root>/<ver>/runtime/glnx86: 
	<mcr_root>/<ver>/sys/os/glnx86: 
	<mcr_root>/<ver>/sys/java/jre/glnx86/jre/lib/i386/native_threads: 
	<mcr_root>/<ver>/sys/java/jre/glnx86/jre/lib/i386/server: 
	<mcr_root>/<ver>/sys/java/jre/glnx86/jre/lib/i386:
setenv XAPPLRESDIR <mcr_root>/<ver>/X11/app-defaults

Solaris 64

setenv LD_LIBRARY_PATH 
/usr/lib/lwp: 
<mcr_root>/<ver>/runtime/sol64: 
<mcr_root>/<ver>/sys/os/sol64: 
<mcr_root>/<ver>/sys/java/jre/sol64/jre1.5.0/lib/sparcv9/native_threads: 
<mcr_root>/<ver>/sys/java/jre/sol64/jre1.5.0/lib/sparcv9/server: 
<mcr_root>/<ver>/sys/java/jre/sol64/jre1.5.0/lib/sparcv9: 
setenv XAPPLRESDIR <mcr_root>/<ver>/X11/app-defaults 

Linux x86-64

setenv LD_LIBRARY_PATH 
	<mcr_root>/<ver>/runtime/glnxa64: 
	<mcr_root>/<ver>/sys/os/glnxa64: 
	<mcr_root>/<ver>/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:

	<mcr_root>/<ver>/sys/java/jre/glnxa64/jre/lib/amd64:
setenv XAPPLRESDIR <mcr_root>/<ver>/X11/app-defaults

Mac OS X

setenv DYLD_LIBRARY_PATH 
	<mcr_root>/<ver>/runtime/mac: 
	<mcr_root>/<ver>/sys/os/mac: 
	<mcr_root>/<ver>/bin/mac: 
	/System/Library/Frameworks/JavaVM.framework/JavaVM: 
	/System/Library/Frameworks/JavaVM.framework/Libraries
setenv XAPPLRESDIR <mcr_root>/<ver>/X11/app-defaults

Intel Mac (Maci)

setenv DYLD_LIBRARY_PATH 
   <mcr_root>/version/runtime/maci: 
   <mcr_root>/version/sys/os/maci: 
   <mcr_root>/version/bin/maci: 
   /System/Library/Frameworks/JavaVM.framework/JavaVM: 
   /System/Library/Frameworks/JavaVM.framework/Libraries 
setenv XAPPLRESDIR <mcr_root>/version/X11/app-defaults 

Note   If you are running a version of Intel Mac later than 10.3, use the bsh, rather than the csh, shell.

Caution   There is a limitation regarding directories on your path. If the target machine has a MATLAB installation, the <mcr_root> directories must be first on the path to run the deployed application. To run MATLAB, the matlabroot directories must be first on the path. This restriction only applies to configurations involving an installed MCR and an installed MATLAB on the same machine.

Executing the Application

Run the magicsquare standalone application from the system prompt and provide a number representing the size of the desired magic square, for example, 4.

magicsquare 4

The results are displayed as:

ans =
    16     2     3    13
     5    11    10     8
     9     7     6    12
     4    14    15     1

Note   Input arguments you pass to and from a system prompt are treated as string input and you need to consider that in your application. For more information, see Passing Arguments to and from a Standalone Application.

Note   Before executing your MATLAB Compiler generated executable, set the LD_PRELOAD environment variable to /lib/libgcc_s.so.1.
