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.

Update 12/04/08: I have now successfully installed the x64 version of Eclipse - see 64 Bit Eclipse: Linux Installation, including PDT, WTP (WST), ATF, and MySQL (SQL Explorer Plugin) for a step by step guide, or continue reading this article if you want to install the 32 bit version.

32 Bit installation

I went through several different methods of installing the Eclipse IDE on my Ubuntu system. I tried the obvious first - installing via the Synaptic Package Manager, but found it a bit of a pain to install any plugin packages I downloaded (I also use WST and SqlExplorer in addition to PDT). So, I uninstalled, then tried the 64 Bit version of the SDK (which at the time was pretty buggy, and unstable), in the hope that I’d be able to plug in a 64 Bit version of the PDT, which I soon found doesn’t exist yet! So, I finally settled for installing the 32 Bit version of Eclipse PDT, which enabled me to install the plugins too.

In order to install and run this successfully, I first downloaded the 32 Bit Java Runtime Environment installer “Linux (self-extracting file)” from http://www.java.com/en/download/linux_manual.jsp (or direct link to the file), and saved the jre-6u3-linux-i586.bin to my desktop.

Once the file downloaded, I opened up a Terminal (Applications -> Accessories -> Terminal), and typed

cd /usr/java

(if the java directory doesn’t exist, it need to be created:

sudo mkdir /usr/java
cd /usr/java

I also wanted a 64 bit version of the JRE installing, so within the /usr/java directory, created two more sub directories:

sudo mkdir 32
sudo mkdir 64

then copied the newly downloaded JRE installation file from the desktop to the /usr/java/32 directory, and made the file executable:

cd 32
sudo mv ~/Desktop/jre-6u3-linux-i586.bin /usr/java/32/jre-6u3-linux-i586.bin
sudo chmod a+x jre-6u3-linux-i586.bin

then execute the binary:

sudo ./jre-6u3-linux-i586.bin

Accept the terms, and so on and so forth… When it says “Done”, it’s, well, done!

ls

should return:

jre1.6.0_03

Note: If you download a newer version of JRE, then you’ll need to change the above commands containing “jre-6u3-linux-i586.bin” to “jre-6u<version>-linux-i586.bin” where <version> is 3, 4, 5 etc.!

Now for Eclipse. I downloaded the latest version from http://download.eclipse.org/tools/pdt/downloads/ (the current stable version is R20080103) - I click on the link for the latest release, and downloaded the pdt-all-in-one-R20080103-linux-gtk.tar.gz file to the desktop. Once it finished, I went back to the terminal, and entered the /opt directory, moved the Eclipse package to the /opt directory, and extracted the new files:

cd /opt
sudo mv ~/Desktop/pdt-all-in-one-R20080103-linux-gtk.tar.gz /opt
sudo tar -zxvf pdt-all-in-one-R20080103-linux-gtk.tar.gz

This extracts the Eclipse IDE into a directory called, oddly enough, “eclipse”. However, I’m experimenting with the 64 bit version too, so I changed the directory name to eclipse32:

sudo mv eclipse eclipse32

As it was, Eclipse wouldn’t run, since it doesn’t know where to find the JRE I’d just installed, so, I had to create a small shell script in order for it to run correctly:

cd eclipse32
gksu gedit eclipse.sh

This opened up a text editor, with a blank file called “eclipse.sh”. The shell script is:

#!/bin/bash
PATH=/usr/java/32/jre1.6.0_03/bin:$PATH
/opt/eclipse32/eclipse

PATH=/usr/java/32/jre1.6.0_03/bin:$PATH should point to the bin directory of the previously installed.

The script also needed to be executable:

sudo chmod 755 eclipse.sh

and I also changed the ownership of all the files and directories to my username:

sudo chown -R username:group *

That was pretty much it - I could run Eclipse by opening a Terminal window and running

cd /opt/eclipse32
./eclipse.sh

which got a little tiresome after the first time, so I created a menu item (System -> Preferences -> Main Menu) which pointed to /opt/eclipse32/eclipse.sh, and even included the png Eclipse logo for the icon

Any plugins can be downloaded, and extracted into the relevant directories - or, installed by the Eclipse Update Manager.

I’ve recently written a post on “Eclipse PDT and MySQL - SQL Explorer Plugin“, for anyone who needs to set up MySQL connections in Eclipse.
