Hi,
I compiled a matlab (R14) application with mcc (with options -R -nojvm -R -nojit -R -nodisplay) to obtain a standalone application.
I generatad the MCR installer and installed the application and the installer on a ubuntu 8.04.2 machine .
I run the stand-alone application from the command line successfully, but I would like to call the application from a php script with a system call (I tried it sucessfuly on a fedora 8 machine) .
I added the LD_LIBRARY_PATH and PATH pointing to the right paths in /etc/apache2/envvar and added PassEnv LD_LIBRARY_PATH PATH to /etc/apache2/mods-enabled/php5.conf and restarted apache.
When I call the application from my php script I get a segmentation fault (see below - I cut and pasted from the html page as I was not able to reproduce the error from the command line) - and the string "segmentation fault" is the only information I get from the error.log file). Do you have any hints ?
Could the problem be related to the fact that the ubuntu machine ia a virtual machine?
Thank you for your help.
