How to install ia32-libs in Ubuntu 14.04 LTS (Trusty Tahr)

I got it finally! Here is my way, and I hope it can help you :)

sudo apt-get install libc6:i386
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs
rm /etc/apt/sources.list.d/ia32-libs-raring.list
apt-get update
exit
sudo apt-get install gcc-multilib

I don't know the reason why I need to install these, but it works on my computer. When you finish installing these packages, it's time to try. Oh yes, I need to tell you. This time when you want to compile your code, you should add -m32 after gcc, for example: gcc -m32 -o hello helloworld.c. Just make clean and make again. Good luck friends.

PS: my environment is: Ubuntu 14.04 64-bit (Trusty Tahr) and GCC version 4.8.4. I have written the solution in my blog, but it is in Chinese :-) - How to compass 32bit programm under ubuntu14.04.
