MATLAB: Does the application compiled with MATLAB Compiler 4.2 (R14SP2) fail with a segmentation violation

aloneenviromentMATLAB Compilersegvstandstandalone

When I run a compiled application, a segmentation fault occurs with the following call at the top of the stack trace:

 Stack Trace:
   [0] libmwmpath.so:mpCombinePathName~(0x411d5280, 0, 0x411b3740 "toolbox_cache-7.0.4-glnx86.xml", 0) + 32 bytes

This bug has been fixed in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:

This error occurs when the HOME environment variable is unset. This environment variable is generally set for a user's home directory, but may be unset by setup and teardown scripts used for batch applications.

To work around this error, set HOME to a valid user's home directory or a directory accessible by the user account running the application

This bug has been fixed in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB Compiler 4.2 (R14SP2) in the way that MATLAB crashes when running a compiled application if the user's HOME environment variable is unset. This issue is being considered for a future release.

To work around this issue, set the HOME environment variable before running your compiled application.

MATLAB: Do I get the run-time error “Failed to find MEX-file on path” when I execute a stand-alone program created using MATLAB Compiler 2.3 on Linux or Solaris

This problem has been fixed in the MATLAB Compiler 3.0 (R13).

For previous versions, the files available for download from the bottom of this page can be used to fix this problem for both Linux and Solaris platforms.

The files you will need to implement this fix are as follows:

$MATLAB\bin\$ARCH\libmatlb.so
$MATLAB\bin\$ARCH\libmatlb.csf
$MATLAB\extern\lib\$ARCH\mglinstaller

(where $MATLAB is your root MATLAB directory and $ARCH is the appropriate architecture for your system)

Please do the following:

1. Save copies of your current files
2. Put the new files in the appropriate directories
3. Recompile your code
4. Redistribute the newly built executable code using the new MGLINSTALLER

Note that the above files have not been fully tested.
