The ADB command could not be found:

Ubuntu 12.04 64-bit settings compatible with 32-bit implementations
Ref:http://www.2cto.com/os/201210/159883.html

My Configure is as follows:

1. **newwork setting:etc/apt/apt.conf
2. Sudo echo "Deb http://archive.ubuntu.com/ubuntu/raring main restricted universe multiverse" >/etc/apt/sources.lis T.d/ia32-libs-raring.list
sudo apt-get update

3. sudo apt-get install Ia32-libs
4. LIB32Z1 lib32ncurses5 lib32bz2-1.0
sudo apt-get install lib32z1
sudo apt-get install lib32ncurses5
sudo apt-get install lib32bz2-1.0

5. **sudo apt-get Install libc6:i386 libgcc1:i386 gcc-4.6-base:i386 libstdc++5:i386 libstdc++6:i386
sudo apt-get install G++-multilib

6 finally OK

sudo apt-get Remove * * * *
