Installation Instructions for Linux Systems
===========================================
1. Install Eclipse 3.3.2 or higher
2. Install Eclipse C/C++ CDT Plugin 4.0 or higher
3. Download the Qt Eclipse Integration package corresponding to your
Linux distribution
4. Find your eclipse/plugins folder
If you installed Eclipse to e.g. /usr/local in step (1.), you will
find the directory /usr/local/eclipse/plugins there.
If you used the package management system of your Linux distribution
to install Eclipse, this directory might possibly be
/usr/lib/eclipse/plugins.
5. Unpack the package
Go to the location where you found the eclipse/plugins directory
(i.e. /usr/local or /usr/lib in the examples in step (4.) ) and
untar the package, e.g.
cd /usr/local
tar xzf ~/Downloads/qt-eclipse-integration-linux.x86-<version>.tar.gz
You might need to be the root user to do that.
6. Start Eclipse with a clean configuration
It is highly recommended by us to start Eclipse once from the
command line with
eclipse -clean
after you unpacked the Qt Eclipse Integration plugins and feature.
This will not change anything in your workspace but will clear
Eclipse's caches.
Uninstallation Instructions for Linux Systems
=============================================
1. Remove the installed plugins and feature
Go to the location where you installed the Qt Eclipse Integration
package, e.g. /usr/local/eclipse or /usr/lib/eclipse, and remove all
files/directories in plugins/ and features/ that start with
com.trolltech.qtcpp
cd /usr/local/eclipse
rm -r plugins/com.trolltech.qtcpp*
rm -r features/com.trolltech.qtcpp*
2. Restart Eclipse with a clean configuration
It is highly recommended by us to start Eclipse once from the
command line with
eclipse -clean
after you removed the Qt Eclipse Integration plugins and feature.
This will not change anything in your workspace but will clear
Eclipse's caches.
Upgrading Instructions for Linux Systems
========================================
If you want to upgrade your Qt Eclipse Integration installation we
highly recommend to first uninstall the older version:
1. Remove the older installed plugins and feature
Like described in step (1.) of the 'Uninstallation Instructions'.
2. Install the newer Qt Eclipse Integration
Like described in 'Installation Instructions'.
3. Restart Eclipse with a clean configuration
Like described in step (2.) of the 'Uninstallation Instructions'.
