When starting scripts from within PresSTORE, e.g. to create previews or per-job-scripts, the use of environment variables may differ from the standard expectations:

On Linux and Solaris, the environment variables from the caller of the start-server script are copied, but the following variables are modified:

• LANG="en_US.UTF-8"
• LC_TIME="C"
• LEXXDIR is set to the PresSTORE home folder
• LD_LIBRARY_PATH is extended
  

On Mac OS X, PresSTORE is called by the launch deamon (also when start-server is called manually), but  the following environment variables are changed:

• LANG="en_US.UTF-8"
• LC_TIME="C"
• DYLD_LIBRARY_PATH="/usr/local/aw/bin"
  

Starting with PresSTORE 4.3.7, the variable DYLD_LIBRARY_PATH will include the previous value of the environment of the start-server call. This means the DYLD_LIBRARY_PATH can be preset with the /etc/bashrc file. Note that each start-server call will overwrite the plist file that controls the environment when running under launch deamon control.

On Windows, PresSTORE is called as a service and takes over the environment of the service controller. The start mechanism does not change environment variables.

The easiest way to make environment variable reflect specific values in a script called from within PresSTORE is to set them at the beginning of the script itself.
