Why do I receive unresolved symbol errors when running a stand-alone application generated by MATLAB Compiler 4.0 (R14) on my HP-UX machine?

On my HP-UX machine, I have used the MATLAB Compiler's MCC command to successfully generate a stand-alone application. However, when I run the application from my system command shell, I receive the following fatal errors:

/userName/matlab/releases/release_4.2Beta/compile>./loop

/usr/lib/dld.sl: Unresolved symbol: sem_post (code) from /userName/matlab/MCR/v72/bin/hpux/libut.sl

These errors generally indicate that the LD_PRELOAD environment variable has not been set correctly.

If the machine running the application has MATLAB installed, LD_PRELOAD can be set correctly using the following command at your system command shell:

 setenv LD_PRELOAD   <matlabroot>/sys/java/jre/hpux/jre1.4.1/lib/PA_RISC2.0/server/libjvm.sl

where _matlabroot _refers to the MATLAB installation directory, which can be determined by entering

 matlabroot

at the MATLAB Command Prompt.

For more information on environment configuration for stand-alone applications running on machines that have MATLAB installed, enter the following at the MATLAB Command Prompt:

web([docroot,'/toolbox/compiler/ch04standalone5.html#995872'])'

If the machine in question does not have MATLAB installed but rather has the MATLAB Component Runtime (MCR) libraries installed, the following command will correctly set the LD_PRELOAD environment variable:

 setenv LD_PRELOAD
 <mcr_root>/<ver>/sys/java/jre/hpux/jre1.4.1/lib/PA_RISC2.0/server/libjvm.sl

where _mcr_root _refers to the MCR installation directory, and <ver> refers to the MCR version.

For more information on environment configuration for stand-alone applications running on machines that have the MCR libraries installed, enter the following at the MATLAB Command Prompt:

web([docroot,'/toolbox/compiler/ch04standalone7.html#995938'])
