Running Google Web Toolkit (GWT) & Eclipse plugin on Debian 64bit
GWT is a very interesting project. You can find a lot of useful plugins and an active community. The main issue is that you can’t run GWT and its Eclipse plugin in a pure 64bit environment.
Here’s my problem: my laptop was a pure 64 bit environment. (Trust me, it was not easy to keep it so “pure” in its 2 years of life)
To run GWT on Debian 64bit, I had to follow the steps mentioned on this GWT issue forum: http://code.google.com/p/google-web-toolkit/issues/detail?id=135#c57. For your convenience, I’ve included the steps below:
// Install 32bit java
* sudo apt-get install ia32-sun-java6-bin
// Configure Eclipse Galileo (Not sure about other versions of eclipse)
* In eclipse goto: Window -> Preferences.
> Expand Java,
> Click on “Installed JREs”
* You’ll see your current JDK in here (mines was openjdk, my 64bit JDK)
> Click “Add”
* I selected “Standard VM”
> Click “Next”
* In the JRE home field, paste in: /usr/lib/jvm/ia32-java-6-sun
> Click “Finish”
* You’ll see your new JRE added to the list in the preferences.
> Keep the 64bit one selected
> Click “OK” to exit from the preferences window
Thats the JRE added, now we need Google Web Toolkit to use it. (Not sure this is 100%
* After creating a new project,
> Right click the project in the navigator
* Goto Google -> Web Toolkit
> Click on “Run/Debug Settings”
* Click on the JRE tab
> Select “Alternate JRE” button
> Choose “ia32-java-6-sun*****” from the dropdown box
> Click “OK”, and “OK” again for the “Project Properties window”
The apt-get install of ia32-sun-java6-bin installed ia32-libs, that contains shared libraries compiled for ia32. However, that was not enough. I was still getting a fatal error with libgtk2.0-0 (not found).
The final step, not listed in the link above, is this:
apt-get install ia32-libs-gtk
Now it works, with some warning, but nothing dangerous 🙂
