3M MT7 manual HotplugDir

44 3M™ MicroTouch™ Software MT 7 User Guide

HotplugDir

Refer to the symbol UdevDir for details.

InitDir

The MT 7 for Linux® software uses an init script, T WDrvStartup, to start and stop the touch driver. Normally, this runs at run level 5. If your init scripts are located in a directory other than /etc/init.d or /etc/rc.d, then set InitDir to the appropriate path.

JavaBinDir

Set this symbol to the path of the Java® runtime en vironment (JRE). This is needed to run the MT 7 Control Panel. If not set, the control panel will use the system’s default “java” program.

LibDir

The MT 7 for Linux® software uses several shared ob jects. The Install script links these into /usr/lib. If your system's libraries are elsewhere, change this variable to point to the correct path. This directory is mandatory and the software cannot run without its libraries in a common library directory.

LSBDir

An init script must adhere to a variety of conventions. Some conventions use files, such as function, in the script directory. The variable InitDir handles these cases.

Some LSB-compliant systems require access to a file 'init-functions' normally found in /lib/lsb. If you have an LSB system and the init-functions file is not in /lib/lsb, you need to change the value of LSBDir.

SEDir1 and SEDir2

Some of the shared objects in the MT 7 for Linux® s oftware require access to objects secured by SELinux. If the Install script detects SELinux, it assigns a security type to some shared objects. The script inspects the directories /usr/selinux/booleans and /selinux/booleans to determine if SELinux is active. If your SELinux is in a directory other than these, change the definition of one of these variables.

SEGivePermission

If the Install script detects SELinux, it assigns the security type texrel_shlib_t to some shared objects. If this is not appropriate for your system, edit the script and change this variable.

UdevDir and HotplugDir

The MT 7 for Linux® software supports hot plugging of USB controllers through either the udev or the hotplug systems. Older versions of Linux® used the hotplug system. The udev system replaced hotplug. It is on most current distributions. The Install script checks for udev support first. It assumes that the udev support files are in the directory /etc/udev/. If udev resides elsewhere, change the definition of UdevDir to the appropriate path.
