GWT Hosted Mode on 64 Bit Ubuntu

As far as I know this still works (for GWT 1.7) but has become obsolete with the release of GWT 2.0!

Here’s how I got GWT 1.7 Hosted Mode to work on my 64 bit Ubuntu Karmic Koala 9.10 laptop. These instructions should also work on Jaunty (9.04)

1. Install ia32-sun-java6-bin:
   

   sudo apt-get install ia32-sun-java6-bin

2. Make sure the default Java installation remains the 64 bit one
   

   sudo update-java-alternatives --set java-6-sun

3. Download libstdc++5 for IA32 from Jaunty repos: http://archive.ubuntu.com/ubuntu/pool/universe/g/gcc-3.3/libstdc++5_3.3.6-17ubuntu1_i386.deb
4. Extract the libstdc++.so.5 file
   

   dpkg-deb --fsys-tarfile libstdc++5_3.3.6-17ubuntu1_i386.deb  | tar -O --extract './usr/lib/libstdc++.so.5.0.7' > libstdc++.so.5

5. Move the extracted file to /usr/lib32
   

   sudo mv libstdc++.so.5 /usr/lib32

6. Run
   

   sudo ldconfig

7. Start GWT:
   

   JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun mvn gwt:run
