[Lazarus] System variables visibility

[John Landmesser]

Hi,

i developed an application ( Linux ) that need to know where 
$ORACLE_HOME points to.

The only way was to start my app with a shell-script, defining:

#! /bin/bash
export ORACLE_HOME=/usr/lib/oracle/....

# run my app
Lazarus_Oracle_app

Had no success defining this variable in bashrc or profile.

But why do i have to define this in my start-script?

Annotation:
perhaps i have to search the sources of ZeosLib, that i'm using because 
of german Umlauts-problems in OracleConnection

Thanks for tipps!!
