QTDIR Environment Variable problem

zombyLINUX · 03-28-2004, 10:35 PM

I have installed qt3 on my laptop machine running SuSE 9.0 with KDE 3.1
windowmanager.

I have a simple project in a direatory called QtWindowWithButtons that
just makes a Qt window with three buttons.

I am able to run qmake and when i run make it cannot find the header
files. This is of course is an include problem. I know that Qt Makefiles
use a QTDIR environment that specifies qt directory...in my case being
/usr/lib/qt3. However, if i say QTDIR=/usr/lib/qt3 and then echo $QTDIR
in Konsole, I get /usr/lib/qt3. This is as expected, but when i type
qmake, then make it uses /include instead of /usr/lib/qt3/include.

This is because i forgot to export QTDIR.

So I did that and it worked fine, however when I reboot of course the environment variable is no longer set. I guess my qeustion is, is there a way to permanently set environment variables. I know that I can modify my .bashrc file to set it whenever I open up a Konsole. But on system boot up, is there like a registry that I can change to set an environment variable. Like the Windows Registry???

Please provide any advice on this matter...

/etc/profile.d/qt.sh

Code:

#!/bin/sh
# Environment variables for the Qt package:
if [ -d /usr/lib/qt3 ]; then
  QTDIR=/usr/lib/qt3
else
  exit
fi
if [ ! "$CPLUS_INCLUDE_PATH" = "" ]; then
  CPLUS_INCLUDE_PATH=$QTDIR/include:$CPLUS_INCLUDE_PATH
else
  CPLUS_INCLUDE_PATH=$QTDIR/include
fi
MANPATH="$MANPATH:$QTDIR/doc/man"
PATH="$PATH:$QTDIR/bin"
export QTDIR
export CPLUS_INCLUDE_PATH
export MANPATH

I had to create the qt.sh file and put it in that directory. Do I need to set up some link to source that shell script when my machine boots. Because I rebooted and no QTDIR was defined. I tested using echo $QTDIR. Maybe I am just missing something...

You'd have to make it executable ...

Code:

# Append any additional sh scripts found in /etc/profile.d/:
for file in /etc/profile.d/*.sh ; do
  if [ -x $file ]; then
    . $file
  fi
done

This is how the files in /etc/profile.d get started...
if it's executable it'll be run for any shell.

Cheers,
