64 Bit Jungle

I’ve been checking out the recently released Eclipse 3.4 (Ganymede), and so far so good. I’ve managed to get PDT (for PHP Development) and SQL Explorer installed and running successfully, so I’ll be doing some testing to see how it compares to Europa, which I have been using for some time. Thankfully, installing plugins is much easier with Ganymede - this is how I got it set up an configured.

IMPORTANT NOTE: This installation configuration currently relies on Integration builds of both PDT and DLTK, since the current Stable builds of each are not currently supported under Eclipse 3.4. I will update this tutorial as support becomes available, but if you are not comfortable installing Integration builds, please see my previous tutorial on setting up a PHP IDE in Eclipse Europa: “64 Bit Eclipse: Linux Installation, including PDT, WTP (WST), ATF, and MySQL (SQL Explorer Plugin)“.

Install Eclipse

Installing Eclipse is a pretty easy task - just head over to http://www.eclipse.org/downloads and download the latest version of “Eclipse Classic” (direct link to 64 bit version). I downloaded the file to my desktop, and once finished, opened up a Terminal window, extracted the archive, and installed Eclipse into the /opt directory:

cd ~/Desktop
tar -zxvf eclipse-SDK-3.4-linux-gtk-x86_64.tar.gz
sudo mv eclipse /opt/ganymede

I installed into /opt/ganymede since I already have Europa installed in /opt/eclipse.

That’s all there is to installing Eclipse. It can be run (for now) via the Terminal:

cd /opt/ganymede
./eclipse

Installing PDT

As mentioned above, the latest Stable build of PDT is not yet supported in Eclipse 3.4, and since only PDT 1.0.x is available via the Update Site, it’s necessary to download the 2.0.x Integration Build from the PDT Website (see this thread at pdt-dev for more information). The same goes for DLTK (Dynamic Languages Toolkit) upon which PDT depends - only the Integration Build may be installed with Ganymede.

Firstly I downloaded DLTK, from http://download.eclipse.org/technology/dltk/downloads - click on the Integration Build download link, and grab the Core Frameworks archive (direct link to current version - Integration Builds are likely to change frequently, so best to visit the main doanload page). Next, grab the PDT archive from http://download.eclipse.org/tools/pdt/downloads/ (click on the 2.0.0 Integration Build link, then grab the PDT Runtime archive - direct link). Don’t worry about the requirements and handy extras.

Once downloaded, again to my Desktop, I created a couple of temporary directories, and unziped both archives into their respective new homes:

mkdir pdt dltk
mv org.eclipse.php_feature-I20080722.zip pdt
cd pdt
unzip org.eclipse.php_feature-I20080722.zip pdt
cd ~/Desktop
mv dltk-core-I-I200807291021-200807291021-incubation.zip dltk
cd dltk
unzip dltk-core-I-I200807291021-200807291021-incubation.zip

Now the Eclipse Update manager can be pointed to these “local sites”. I fired up Eclipse once again, and navigated to the Update Manager: Help -> Software Updates. Once open, I clicked on the Available Software tab, and added the new sites - click on Add Site, click Local, and navigate to ~/Desktop/pdt/eclipse. Click OK, and repeat for ~/Desktop/dltk/eclipse. Now there should be two more sites (”/home/username/Desktop/pdt/eclipse” and “/home/username/Desktop/dltk/eclipse”) in addition to “Eclipse Project Update Site” and “Ganymede” (or “http://download.eclipse.org/releases/ganymede”). Expand each of the two new sites, and select the lowest leaf in each tree - “PDT Feature” and “Dynamic Languages Toolkit”.

PDT is also dependent upon the Graphical Editing Framework (GEF), so expand the Ganymede tree, then “Graphical Editors and Frameworks” and select the “Graphical Editing Framework GEF” option.

Don’t click “Install” quite yet - there are a few other additional things to select for a full Web Application Development IDE.

Web Application stuff

Expand the main Ganymede tree, and “Web and Java EE Dvelopment”. I personally selected:

• Eclipse XML Editors and Tools
• Javascript Developer Tools
• Web Developer Tools
• Web Page Editor

You may want more, or less. Almost there…

Database Integration

Expand Database Development, and select Data Tools Platform Enablement and Data Tools Platform SQL Development. These are required for setting up a connection to MySQL later.

OK, click Install! Go and make a brew, or coffee - this may take some time.

Once everything has been downloaded and installed, restart Eclipse.

SQL Explorer Plugin

I find SQL Explorer is a great little plugin to use as a DB GUI. To install it, I downloaded the latest version to my Desktop, and extracted the files.

cd ~/Desktop
mkdir sqlexplorer
mv sqlexplorer_plugin-3.5.0.RC5.zip sqlexplorer
cd sqlexplorer
unzip sqlexplorer_plugin-3.5.0.RC5.zip

As with the PDT and DLTK plugins, to install is just a simple case of adding a new Local site to the Eclipse Update Manager, and selecting the plugin to install. So, open up the Update Manager - Help -> Software Updates, and select the Available Software tab. Add new site, click Local, navigate to ~/Desktop/sqlexplorer, click OK, etc. Once the site is added, expand the new SQL Explorer, select the lowest level leaf, and click install.

Once installed, restart Eclipse. Some configuration is still required to get SQL Explorer linked up to a MySQL Database, which I have covered in a previous tutorial: Eclipse PDT and MySQL - SQL Explorer Plugin. It’s pretty simple, and just involves downloading the Java Connector for MySQL, and pointing Eclipse to it.

ATF (AJAX Toolkit)

Unfortunately, ATF is not yet supported in Ganymede - I’m keeping track of it, however, and will update this tutorial as soon as support is available. In the mean time, check out the current status at atf-dev.

Debugging PHP with Xdebug

The information in my previous tutorial, Debugging PHP Applications with Xdebug and Eclipse PDT, can still be applied to Ganymede.

Hope that helps.

NOTE, 04/08/08: This tutorial covers Eclipse Europa. If you would like to install the latest version of Eclipse 3.4 Ganymede, with PDT and SQL Explorer, take a look at my latest Tutorial: “64 Bit Eclipse 3.4 (Ganymede) IDE with PDT and SQL Explorer - Full PHP/MySQL Web Application IDE“.

I had tried once before to install the x64 (64 Bit) version of Eclipse IDE, about 8 months ago, but found it to be somewhat buggy and unstable. In the interim, I’ve been using the 32 Bit version of Eclipse PDT for my development stuff. Earlier this year (21/02/08) a new version of Eclipse 64 Bit was released, so I gave it a go today. So far, so good!

Unfortunately, there’s no 64 Bit PDT all-in-one, but I managed to install a 64 Bit equivalent by cobbling together the relevant packages available by using the Eclipse Update Manager system, after initially installing the latest version of Eclipse Classic 3.3.2 64 Bit.

I wanted to keep everything (or as much as possible) 64 Bit, so I also download and installed the 64 Bit JRE, which can be downloaded here (or use the direct link to the bin file). The method for installing the 64 Bit JRE is the same as the 32 Bit version - after the file downloaded to my desktop, I opened up a new Terminal Window (Applications -> Accessories -> Terminal), traversed to the directory I wanted to install it into, moved the file, made it executable, and ran it to install:

cd /usr/java
sudo mkdir 64
cd 64
sudo mv ~/Desktop/jdk-6u5-linux-x64.bin /usr/java/64/
sudo chmod a+x jdk-6u5-linux-x64.bin
sudo ./jdk-6u5-linux-x64.bin

If the “java” directory doesn’t exist, it needs to be created first:

sudo mkdir /usr/java

listing the directory

ls

should return

jre1.6.0_05

which is the directory containing the necessary Java binaries.

As with my previous 32 Bit installation, I wanted Eclipse to be installed in the /opt directory:

cd /opt
sudo mv ~/Desktop/eclipse-SDK-3.3.2-linux-gtk-x86_64.tar.gz /opt
sudo tar -zxvf eclipse-SDK-3.3.2-linux-gtk-x86_64.tar.gz

then rename the eclipse directory:

sudo mv eclipse eclipse64

I also needed to get the newly installed Eclipse to run with the newly installed JRE - by default, the eclipse executable in the directory will try and detect Java and use whatever it finds, so I created a shell script:

cd eclipse64
sudo gksu gedit eclipse.sh

containing the following:

#!/bin/bash
PATH=/usr/java/64/jre1.6.0_05/bin:$PATH
/opt/eclipse64/eclipse

Now instead of running the eclipse executable, I run eclipse.sh (make sure it’s executable)

sudo chmod 755 eclipse.sh

before running

/opt/eclipse64/eclipse.sh

PDT and WTP Plugins

The first time I ran the new 64 Bit version, everything went well - it was fast, and seemed stable, so I went ahead and started installing all the additional plugins I needed (and still need…). Goto Help -> Software Updates -> Find and Install, and select “Search for new features to install”.Click on “New Remote Site” for each of the following:

• Name: PDT, URL: http://download.eclipse.org/tools/pdt/updates/
• Name: WTP, URL: http://download.eclipse.org/webtools/updates/
• Name: GEF, URL: http://www.eclipse.org/gef/updates/
• Name: EMF, IRL: http://www.eclipse.org/modeling/emf/updates/

Actually, there are only a couple of components required from the GEF (Graphical Editing Framework) and EMF (Eclipse Modeling Framework) packages to satisfy dependencies - WTP (Web Tools Platform) requires a package from GEF, and GEF from EMF…

After adding these, click on Finish - the Update Manager will then query any mirrors for the latest versions of the plugins. Once it has finished, a dialog appears, where it is possible to select the plugins to download and install. First, I selected PDT - the Update Manager then informed me that PDT requires files from WTP, so I tried clicking the “Select Requires” button, hoping that it would sort out the dependencies on my behalf. Unfortunately, nothing happened… So, I selected WTP manually, then expanded GEF -> Eclipse SDK R3.3.1 and Selected Graphical Editing Framework 3.3.1v20070814, then expanded EMF -> EMF SDK 2.3.2 and selected Eclipse Modeling Framework (EMF) - org.eclipse.emf.ecore 2.3.2v200802051830… I could then click “Select Required” to get the last few residual required dependencies… Phew…

Actualy, it still bugged me for dependencies for Java Persistence API contained in WTP, but by that stage I really couldn’t be arsed going through the process of adding more stuff to the Update Manager and potentially having to search for further dependencies, so I just deselected the three Java Persistence API files contained in WTP.

OK, with the dependencies sorted, I clicked Next, accepted the agreements, finished, and went to make, and drink a brew (that’s Tea) while the Update Manager downloaded and installed the requested stuff.

MySQL: SQL Explorer Plugin

Once everything had downloaded and installed, I restarted Eclipse. Everything looked good! Great, in fact. But I also wanted to install a few more plugins, including the MySQL SQL Explorer Plugin - which additionally requires, and depends on Eclipse DTP (Data Tools Project). Eclipse DTP has to be downloaded and installed manually, since there is no automated Update Site. So, I downloaded dtp_1.5.2_022008.zip to my Desktop, and set about extracting and installing the files:

cd ~/Desktop
mkdir DTP
mv dtp_1.5.2_022008.zip DTP
cd DTP
unzip dtp_1.5.2_022008.zip
cd eclipse
sudo cp -R features plugins /opt/eclipse64

If Eclipse is open, restart it. With the DTP installed, I could set about installing the SQL Explorer Plugin. The instructions for installing and configuring the SQL Explorer Plugin can be found in my previous article - Eclipse PDT and MySQL - SQL Explorer Plugin, since I don’t want to regurgitate information, just follow the link if you need to install it, and come back when it’s done.

Note: Actually, now I had the DTP installed, I could download and install the additional Java Persistence API in WTP! Same method: Update Manager, select WTP etcetera, etcetera…

ATF: AJAX Framework Toolkit

Once the SQL Explorer Plugin was installed, I had one final plugin - ATF (the AJAX Toolkit Framework). This can be downloaded as a Site Archive, and the zip file added to Eclipse’s Update Manager. Once downloaded, I opened the Update Manager in Eclipse (Help -> Software Updates -> Find and Install), and clicked on “New Archived Site”, to add a new locally archived site, calling it ATF, and pointing it to the freshly downloaded atf-incubation-SiteArchive-0.2.3M4-v200709141050.zip file. I discovered, however, that the site.xml file contained within the zipped site archive is somewhat out of date and the pointers within are directed to the wrong download locations, so I had to manually locate the additional dependent plugins - Mozilla XULRunner, and Mozilla JS. They can both be added as New Remote Sites to the Update Manager, by clicking on the “New Remote Site” button, and adding the following information:

• Name: Mozilla JS, URL: http://ftp.mozilla.org/pub/mozilla.org/js/eclipse/
• Name: XULRunner, URL: http://releases.mozilla.org/pub/mozilla.org/xulrunner/releases/1.8.1.3/contrib/eclipse/

The previously used EMF plugin is also required to satisfy a couple of dependencies, so I selected the ATF, Mozilla JS, XULRunner, and EMF plugins from the list, and clicked Finish. Once the “updates” were found, I selected XULRunner, Mozilla JS, ATF (I deselected the ATF -> Mozilla JS component though, since an updated version was to be downloaded and installed from the Mozilla Server), and also selected the required EMF components. Click through Next etc. to download and install. Once completed, I restarted Eclipse.

In the Window -> Preferences menu by the way, AJAX toolkits such as Script.aculo.us can be added to the ATF module.

Et Voila! I now have a working Eclipse 64 Bit version up and running! Finally!

Oh, if you want a desktop icon, just create a file on your Desktop called Eclipse.desktop,

cd ~/Desktop
gedit Eclipse.desktop

and add the following:

[Desktop Entry]
Categories=;
Encoding=UTF-8
Exec=/opt/eclipse32/eclipse.sh

Icon=/opt/eclipse64/icon.xpm
Icon[en_US]=/opt/eclipse64/icon.xpm
