GWT Hosted Mode on 64 Bit Ubuntu

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)

source: from this blog

1. Install ia32-sun-java6-bin:
   
   1. sudo apt-get 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
   
   1. sudo update-java-alternatives --set java-6-sun

   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
   
   1. 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

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

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

6. Run
   
   1. sudo ldconfig

   sudo ldconfig

7. Start GWT:
   
   1. JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun mvn gwt:run

How to change the Ubuntu Loading screen

Both have to be ran otherwise the change you make with step one will not take effect.

convert .wav to .row

Digg Inside *.dmg File

That being said - .dmg files are just compressed files, and you CAN access them - although it probably won't be of much use since you still won't be able to run the binaries enclosed within. Go to this web site, and download dmg2img source code. Now, you will need the build-essential package in order to compile from source code, so open up a terminal and type:

Code:
sudo apt-get install build-essential

Now, you need to compile dmg2img. In the terminal, use 'cd' to get to wherever the source code archive downloaded to, then:

Code:
tar -zxvf ./dmg2img.tar.gz
cd dmg2img
make all

Once that's done, use the following commands to convert, then mount, the .dmg file:

Code:
./dmg2img -i /path/to/dmg_file_to_convert.dmg -o /path/to/img_file_to_output.img
sudo modrobe hfsplus
sudo mount -t hfsplus -o loop /path/to/img_file.img /mount_point

Now you need to change to the mounted directory, and you'll be able to see the files contained in the .dmg file:

Code:
cd /mount_point
ls

Hope that helps! At least you'll be able to see what's inside the .dmg file.

If you can find Mac software which is open source, you me able to compile a version so that it runs on Linux.

Remove MBR using dd command
