On trying to start Maestro I get this error. What does it mean?

schrodinger_dir: error while loading shared libraries:
/home/schrodinger/maestro-v90111/lib/Linux-x86/libifcore.so.5: cannot restore segment prot after reloc: Permission denied

This message is usually produced because the SELinux security settings are enabled, and these settings prevent Maestro from loading. If you do not get the "Permission denied" message when you log in as root and start Maestro, the problem is most likely the security settings. The library listed in the error message can depend on the particular Linux that you are running.

The first solution is to disable the SELinux security settings, by logging on as root and issuing the following command:

setenforce 0

This command turns off the SELinux security until the machine is rebooted. To turn off the settings permanently, log on as root, open /etc/sysconfig/selinux in a text editor, and ensure that you have the following line in this file:

SELINUX=disabled

If you do not want to disable SELinux security, you can run one of the following commands:

chcon -t texrel_shlib_t `find $SCHRODINGER -name \*.so\*`

or

find $SCHRODINGER -name \*.so\* | xargs chcon -t texrel_shlib_t

If the first of these doesn't work, the second should. These commands must be run when logged in as the user who installed the software, with $SCHRODINGER defined.
