MATLAB: Does the standalone application that calls SORTROWS not work on a machine that does not have MATLAB installed

MATLAB C/C++ Math Librarymexsortcellcharsortrowssortrowscstandalone

I have the following code:

function testexe
a=ceil(10*rand(3,10));
sortrows(a);

I compiled in MATLAB using the following command

mcc -m testexe.m -v

Now when I distribute and run my application, testexe.exe, along with the mglinstaller.exe, on a client machine that does not have MATLAB, installed I get the following error:

Failed to find MEX-File on path : sortrowsc.dll.

 EXITING

Sometimes the error is referring to another MEX-file sortcellchar.dll.

This is a bug in the MGLINSTALLER with the C/C++ Math Library 2.2. This problem has been fixed in MATLAB C/C++ Math Library 2.4 (R13).

If you are using a previous version, see the information below:

This error occurs because the client computer does not have the MEX-file sortrowsc.dll. This MEX-file does not come packaged with the mglinstaller. In order to distribute a stand-alone application that calls sort rows, sortrowsc.dll and/or sortcellchar.dll, must also be distributed. The libraries can be placed in the same directory as the executable or in the bin\win32 directory created by the MGLINSTALLER.

MATLAB: Do I receive a linking error about mclInitializeApplication_proxy and mclmcrInitialize_proxy when I compile the driver application that calls a C++ shared library compiled using MATLAB Compiler 4.10 (R2009a)

This error may occur only with MATLAB Compiler 4.8 (R2008a) or later versions because of changes that have been introduced in mclmcrrt.h and mclmcr.h, which impose the requirement that mclmcr.h always be included after mclmcrrt.h for the pre-processing stage.

In the attached driver application, the following code is found on Lines 1-2:

#include "mclcppclass.h"
#include "Test.h"

Here, mclcppclass.h (found in the <matlabroot>/extern/include directory) in turn includes mclmcr.h.

Also, in the generated Test.h file, the following code can be found:

#include "mclmcrrt.h"
#include "mclcppclass.h"

This results in mclcppclass.h being included before mclmcrrt.h, thus causing a symbol resolution issue for the identifiers mclInitializeApplication_proxy and mclmcrInitialize_proxy.

In order to resolve this issue, change the order of the header files in mydriver.cpp to the following:

#include "Test.h"
#include "mclcppclass.h"

Also, since Test.h already includes mclcppclass.h, you can entirely avoid including this header file in your driver application.

MATLAB: Do I get the error “cannot find ***.dll” when I distribute a stand-alone application to a Japanese Win2000 PC using the MGLINSTALLERr

There is no Japanese version of the MGLINSTALLER. The problem occurs because the current MGLINSTALLER does not include a DLL called

 comp_ja.dll

in the $MATLAB\bin\win32.(where $MATLAB is the MATLAB installation directory). This is needed for Japanese PCs.

Therefore, the resolution is to copy this file, comp_ja.dll, into the bin/win32 directory created by the MGLINSTALLER.
